A power cut can turn a long render, game save, or work document into a recovery exercise before you even reach the wall switch. The right UPS gives your computer enough time to stay stable, save files, and shut down cleanly instead of dropping power without warning. Our Best best ups for pc guide covers compact backups for a single desk as well as larger units for demanding desktops, NAS devices, and full home offices.
The important differences are not just the VA and watt figures. Outlet layout, pure sine wave output, automatic voltage regulation, battery chemistry, runtime, and replaceable batteries all affect how useful a UPS will be after it sits quietly under your desk for months.
For most people, the APC BR1500MS2 is the strongest all-around pick, while the other nine cover smaller desks, higher-efficiency lithium designs, and more modest computer setups.

1. APC BR1500MS2: Best Overall
Pros
- 900W capacity handles demanding desktop systems
- Pure sine wave output suits modern PC power supplies
- LCD shows runtime and watt draw
- USB C and USB A charging ports
- Six battery-backed outlets
Cons
- Heavy at 27.55 pounds
- Larger than compact desk UPS units
- Fan and alarm behavior may matter in quiet rooms
Best for: anyone who wants clean backup power for a powerful PC, monitor, router, and storage devices.
The APC BR1500MS2 is the UPS we would choose for a serious desktop because it covers the parts that are easy to overlook. It has enough headroom for a 900W load, six of its 10 outlets provide battery backup, and the pure sine wave output is a sensible match for modern computers with Active Power Factor Correction power supplies. It feels designed for a complete workstation rather than just a tower and one screen.
The LCD is especially useful. It shows remaining runtime, current watt draw, and battery health, so you can see whether your setup is lightly loaded or already close to the limit. The advertised runtime reaches 73 minutes at a 100W load, though a gaming PC or workstation pulling substantially more power will run for less time. That distinction matters. A UPS is mainly there to bridge a short interruption and give you time to save work, not to operate a powerful computer indefinitely.
APC adds automatic voltage regulation, which corrects low or high voltage without immediately using the battery. That can preserve battery runtime during brownouts and reduce unnecessary cycling. Coax and Ethernet surge protection extend coverage beyond the AC outlets, while the front USB C and USB A ports let you charge small devices without taking up a protected outlet.
The main weakness is physical. At 27.55 pounds and 14.49 inches long, the BR1500MS2 needs a deliberate home under or beside the desk. The APC BX1500M is similar in capacity and gives you the same total outlet count, but the BR1500MS2 is the better fit for modern PCs because it adds pure sine wave output and a more informative display. Choose this model if your computer has an expensive graphics card, a NAS, or several displays. Skip it if you only need to protect a small office PC and router.
2. APC BX1500M: Best for Larger Offices
Pros
- 1500VA/900W capacity
- Up to 68 minutes at a 100W load
- Ten outlets with five battery-backed positions
- Automatic voltage regulation
- Replaceable battery
Cons
- 24.25-pound chassis takes up desk-side space
- Output is not listed as pure sine wave
- No front USB C charging described
Best for: a home office with a computer, monitor, router, NAS, and several peripheral devices.
The APC BX1500M makes sense when the problem is not just protecting a PC, but keeping an entire work area organized during an outage. Its 1500VA/900W capacity matches the BR1500MS2 on paper, and the 10 outlets are split between five battery backup positions and five surge-only positions. That leaves room for a computer and monitor on battery while printers, speakers, lamps, or other less critical equipment use surge protection only.
Its runtime claim is up to 68 minutes at a 100W load. As with every UPS, that number changes with the connected load, but it shows the BX1500M is intended to keep lower-power office equipment running for more than a quick shutdown window. Automatic voltage regulation handles low voltage from 88V and trims surges of plus or minus 13 percent without draining the battery. That is useful in homes where voltage dips are more common than full blackouts.
The BX1500M also includes coaxial and Ethernet surge protection. Those connections can be overlooked when people protect only the power cable, particularly with a modem, router, or NAS nearby. The user-replaceable battery is another practical advantage. A UPS becomes much less useful when its battery ages, so the ability to replace it without replacing the whole unit matters for a long-lived office setup.
The BR1500MS2 is a better choice for a high-end PC that specifically benefits from pure sine wave output, and its display provides more immediate information. The BX1500M is the calmer choice for a mixed office because it has clear outlet separation and strong voltage management. It is large, heavy, and less feature-rich at the front panel, so small desk owners should look at the APC BE650G1 instead.
3. GOLDENMATE 1000VA/800W White: Best Lithium 800W Model
Pros
- 800W pure sine wave output
- LiFePO4 battery rated for over 10 years and more than 5000 cycles
- Eight battery-backed outlets
- LCD panel shows battery and power conditions
- Buzzer can be muted
Cons
- Cooling fan activates during heavy battery use
- Requires suitable ventilation
- No runtime figure is provided in the listed features
Best for: a modern desktop or workstation owner who wants lithium battery chemistry and pure sine wave output.
The GOLDENMATE 1000VA/800W White stands apart from the APC models through its LiFePO4 battery and eight battery-backed outlets. That outlet arrangement is convenient if nearly everything on the desk needs to remain active during an outage. There is no need to decide which of several accessories belongs on a surge-only outlet, although the total load still needs to stay within the 800W rating.
The pure sine wave output is a good match for desktop power supplies, workstations, network devices, and telecom equipment. GOLDENMATE lists a battery lifespan of over 10 years and more than 5000 charge cycles. Those figures describe the battery design rather than guaranteed runtime for a particular computer, and the product listing does not provide a runtime figure at a defined load. The LCD helps fill that practical gap by showing current battery and power conditions.
A built-in battery management system monitors the battery, while the cooling fan is specified below 50 dB. The fan activates when the system detects heavy battery usage, so it should not be treated as a completely silent unit in a long outage. The buzzer can be muted with the switch below the LCD, and the safety system stops charging or discharging when limits are exceeded.
Compared with the GOLDENMATE 1000VA/600W models, this version gives a PC more wattage headroom. The GOLDENMATE 1500VA/1000W goes further still, but it is a better fit for especially demanding setups. The white 800W model is a strong middle ground for a workstation, though its 12.99 inch length and need for open ventilation make it less suitable for a cramped cabinet. Anyone buying it should verify the household outlet voltage, since the unit is designed for 90V to 140V AC input.
4. APC BE650G1: Best Compact APC
Pros
- 650VA/390W capacity suits modest PC systems
- Up to 29 minutes at a 100W load
- Eight well-spaced outlets
- Four battery-backed outlets and four surge-only outlets
- Replaceable battery and muteable alerts
Cons
- 390W limit is unsuitable for powerful gaming PCs
- No LCD runtime display
- Unusual wide, low chassis may not suit every shelf
Best for: a compact office computer, router, external drive, or NAS setup.
The APC BE650G1 is the sensible small-system pick because it does not pretend to be a workstation UPS. Its 650VA/390W capacity is aimed at modest computers, Wi-Fi equipment, modems, external drives, and NAS devices. For that role, the eight well-spaced outlets are more useful than a large capacity number that leaves a small desk with a bulky box.
Four outlets provide battery backup and surge protection, while the other four provide surge protection only. The split is easy to understand: put the computer, monitor, and networking equipment on the first group, then use the remaining outlets for speakers or other gear that does not need to stay powered. At a 100W load, APC lists up to 29 minutes of runtime, giving a low-power setup time to save work and shut down.
The BE650G1 uses status indicators and muteable audible alerts rather than an LCD. That keeps the interface simple, but it means you will not get a live watt reading or a precise runtime estimate from the front panel. The battery can be replaced with APC’s RBC17 model, which is important for an appliance intended to protect a NAS or home office over several years.
The APC BE600M1 is smaller and lighter, but it has only 330W of capacity and five battery-backed outlets. The BE650G1 is the better choice if you need a few more connections and can accommodate its 11.18 inch width. It is not the right UPS for a gaming tower with a high-power graphics card. For that, move up to the APC BR1000MS or BR1500MS2.
5. APC BR1500MS2: Best Pure Sine Wave Capacity
Pros
- Pure sine wave output
- 1500VA/900W capacity
- Active PFC compatibility
- Six battery-backed outlets
- LCD with runtime and load information
Cons
- Large and heavy
- Battery replacement is an eventual maintenance task
- The high capacity is unnecessary for a small PC
Best for: a sensitive or power-hungry PC that needs clean output and useful shutdown time.
The APC BR1500MS2 appears twice in the supplied product set, so this section covers the same model and same listing as the first pick rather than treating it as a different UPS. Its distinction here is the pure sine wave output. That is the feature to focus on if your desktop uses an Active PFC power supply or if you want the cleanest match to utility-style power.
With 900W available, it has substantially more room than the 600W APC BR1000MS and the 390W BE650G1. The six battery-backed outlets can handle a tower, displays, router, and storage, while four surge-only outlets leave room for devices that do not need outage runtime. The LCD displays minutes of runtime and current watt draw, which makes it easier to identify an overloaded setup before a real outage exposes the problem.
Automatic voltage regulation keeps the battery from being used for every small voltage swing. The BR1500MS2 also protects coax and Ethernet lines, includes USB C and USB A charging, and supports a replaceable APCRBC163 battery. A three-year warranty is listed among its features. These are practical details for a UPS that may spend most of its life unnoticed.
The weakness remains the same: this is a substantial 27.55-pound unit. A smaller computer does not gain much from carrying that extra capacity, and the APC BR1000MS is easier to justify for a typical desktop with a few peripherals. Choose the BR1500MS2 when your PC load, storage equipment, or monitor count makes 900W capacity useful.
6. GOLDENMATE 1000VA/600W White: Best Lithium 600W Model
Pros
- LiFePO4 battery with over 10 years of listed lifespan
- Pure sine wave output
- Eight battery-backed outlets
- LCD status panel
- Battery management and safety controls
Cons
- 600W capacity limits powerful desktops
- Fan activates during heavy battery use
- No defined runtime figure in the listed features
Best for: a home office PC, network setup, or moderate workstation that benefits from lithium battery chemistry.
The GOLDENMATE 1000VA/600W White is built around longevity rather than maximum computer capacity. Its LiFePO4 battery is listed with over 10 years of use and more than 5000 charge cycles, while the pure sine wave output is suited to computers, workstations, network devices, and telecom equipment. That combination makes it more interesting than a basic small UPS for a desk that needs protection every day.
All eight NEMA 5-15P outlets provide surge protection and battery backup. That is simpler than the mixed outlet layout on the APC units, though it also makes load management more important. The computer, screen, router, and external drives can all remain on battery, but their combined demand must stay within the 600W rating.
The LCD reports battery and power conditions, and the built-in battery management system is intended to stop charging or discharging when limits are exceeded. The cooling fan remains below 50 dB according to the listed feature, but it activates during heavy battery usage. The buzzer can be muted from the multifunction switch. These controls are useful, but the product does not state a runtime at a particular load, so do not assume the capacity number translates directly into minutes.
This model is lighter than the APC BR1500MS2 at 10.58 pounds, making it easier to place beside a desk. The GOLDENMATE 1000VA/800W White is the better pick for a more demanding PC, while the 600W model suits office desktops and midrange systems. Check that it has open airflow and a standard 110V household connection before installation.
7. GOLDENMATE 1000VA/800W Gray: Best Gray Lithium Model
Pros
- 800W pure sine wave output
- Eight battery-backed outlets
- LiFePO4 battery rated for over 10 years
- LCD provides power and battery information
- Muteable buzzer
Cons
- Heavy cooling may be audible during battery operation
- Requires ventilation
- No stated runtime at a specific computer load
Best for: a workstation owner who needs 800W capacity and prefers the gray finish.
The GOLDENMATE 1000VA/800W Gray is functionally the gray counterpart to the white 800W model. Its reason to exist in this list is straightforward: it provides a pure sine wave, 800W output with eight battery-backed outlets in a lithium UPS chassis. That gives a workstation more headroom than the 600W GOLDENMATE models without moving all the way to the 1000W unit.
The LiFePO4 battery is listed for over 10 years and more than 5000 charge cycles. That chemistry is suited to users who want a UPS that can remain in service for a long time, especially when the unit is used to protect a computer and network equipment rather than only a single tower. The listing also describes protection from outages, voltage drops, spikes, fluctuations, and surges.
The front LCD provides live battery and power information, while the battery management system monitors operation and can halt charging or discharging when limits are exceeded. The cooling fan is specified below 50 dB and turns on during heavy battery usage. That is a sensible safety feature, but the gray model should not be installed in an enclosed cabinet simply to keep it out of sight.
The APC BR1000MS offers a defined runtime figure and more outlets, though it has a lower 600W capacity. The GOLDENMATE 1000VA/800W Gray is more compelling when battery longevity and pure sine wave output matter more than a precise runtime estimate. It weighs 12.35 pounds and is 12.99 inches long, so it remains manageable beside a desk. Confirm that your supply falls within its listed 90V to 140V AC input range.
8. GOLDENMATE 1500VA/1000W: Best Lithium Capacity
Pros
- Highest listed capacity at 1500VA/1000W
- Pure sine wave output
- LiFePO4 battery
- Communication port supports automatic computer shutdown
- USB C and USB A charging
Cons
- Only eight outlets
- Battery cycle claim is lower than the 1000VA GOLDENMATE models
- Generator compatibility has important limitations
Best for: a high-load workstation, NAS, or computer setup that needs 1000W capacity and lithium battery technology.
The GOLDENMATE 1500VA/1000W is the capacity leader in this group. It is the model to consider when a powerful desktop, several displays, storage, and networking equipment push beyond what a 600W or 800W UPS should handle. Pure sine wave output makes it appropriate for computers, workstations, network devices, and telecom equipment.
Its eight NEMA 5-15P outlets all provide battery backup and surge protection. That is fewer total outlets than the APC 1500VA models, but every position is available for equipment that needs to remain powered. The communication port and included USB cable can connect to a Windows PC, Mac, or NAS, allowing compatible equipment to begin a safe shutdown during an outage. That feature can prevent file corruption when nobody is nearby to intervene.
The LCD shows current battery and power status, and the display turns itself off after 90 seconds of inactivity. Separate controls manage the screen and buzzer, including a mute setting that can remain active until the UPS is powered on again. Two front charging ports, one USB C and one USB A, provide a total of 10W for small devices.
The battery is rated for over 10 years and more than 3000 charge cycles, which is still a substantial maintenance-free lifespan but a different claim from the 5000 plus cycles listed for the smaller GOLDENMATE units. The unit weighs 11.02 pounds, and its cooling fan is specified below 50 dB. Pay close attention to the generator warning: generator-supplied power may not meet the required voltage, frequency, waveform, or grounding conditions. This is the right pick for a demanding fixed setup, not a general-purpose generator companion.
9. GOLDENMATE 1000VA/600W Gray: Best Gray 600W Model
Pros
- 600W pure sine wave output
- LiFePO4 battery
- Eight battery-backed outlets
- LCD monitoring
- Compact 10.58-pound design
Cons
- No specified runtime at a defined load
- Fan operates during heavy battery use
- 600W capacity is not suited to top-tier gaming systems
Best for: a moderate desktop and networking setup in a gray-finish lithium UPS.
The GOLDENMATE 1000VA/600W Gray shares its core design with the white 600W model, including the LiFePO4 battery, pure sine wave output, LCD panel, and eight battery-backed outlets. The practical distinction is the finish, so the choice between them is mainly about how the unit fits the surrounding equipment. Both are aimed at computers, workstations, network devices, and telecom equipment rather than very high-draw gaming rigs.
The lithium battery is listed for over 10 years and more than 5000 charge cycles. That makes the model attractive for a desk where the UPS is expected to remain installed and ready without regular battery replacement. Its battery management system continuously monitors conditions and can stop charging or discharging when limits are exceeded. A low-noise fan operates below 50 dB in the listed specifications, though it activates when battery demand is heavy.
All eight outlets provide both surge protection and battery backup. That is convenient for a computer, display, router, modem, and external storage, but it removes the APC style of separating critical and noncritical equipment. You need to watch the combined draw yourself. The LCD gives useful battery and power information, yet the supplied features do not state how many minutes the UPS provides at a specific load.
The APC BE650G1 is a better compact option for a smaller system with a defined 100W runtime figure, while the GOLDENMATE offers pure sine wave output and a longer-lived lithium battery design. Its 10.58-pound weight is reasonable, but the 12.99 inch length still calls for a clear spot with ventilation. Choose the gray model when those features fit your system and the 600W ceiling leaves comfortable headroom.
10. APC BR1000MS: Best Mid-Size Pure Sine Wave
Pros
- 1000VA/600W pure sine wave output
- Up to 42 minutes at a 100W load
- Ten outlets with six battery-backed positions
- LCD shows runtime and watt load
- USB C and USB A charging
Cons
- 22.44-pound chassis is heavy for a 600W model
- Tall 14.5-inch design needs careful placement
- Battery is replaceable but not maintenance-free
Best for: a desktop PC with several peripherals that needs pure sine wave output without moving to a 900W model.
The APC BR1000MS fills the space between compact APC units and the large 1500VA models. It provides 1000VA/600W pure sine wave output, six battery-backed outlets, and four surge-only outlets. That is enough to protect a tower, monitor, router, and storage while leaving the remaining connections for peripherals that do not need battery power.
APC lists up to 42 minutes of runtime at a 100W load. A computer drawing more power will reduce that figure, but the stated test point gives a useful sense of how a light office setup may behave. Automatic voltage regulation boosts low voltage and trims high voltage without immediately switching to battery. Coaxial and Ethernet surge protection add coverage for connected network equipment.
The angled LCD shows remaining runtime, power load in watts, and system status. The front USB C and USB A ports share a 5V/3A output, so phones and tablets can charge without occupying a protected AC outlet. A replaceable APCRBC160 battery helps extend the usable life of the UPS, and the pure sine wave output is a better match for modern computer power supplies than a basic simulated waveform.
The BR1000MS is unusually heavy at 22.44 pounds and stands 14.5 inches high. The GOLDENMATE 1000VA/600W models are much lighter and use LiFePO4 batteries, but they provide no stated runtime at a defined load and have eight rather than 10 outlets. Choose the APC when its runtime display, outlet count, and familiar voltage management matter more than weight. It is a strong choice for a conventional desktop with several accessories.
How to choose best ups for pc
Choosing among the Best best ups for pc models starts with the computer's actual power needs, then moves to the quality of the output and the equipment you want to keep alive.
Watt capacity
VA describes apparent power, while watts describe the load the UPS can actually support. For a PC, the watt figure is the more useful limit. A 390W unit such as the APC BE650G1 suits a modest office computer, but a gaming tower and monitor can make a 600W UPS feel restrictive. Leave headroom rather than sizing the unit right against the computer's expected maximum.
Pure sine wave output
Pure sine wave output more closely matches utility power and is particularly sensible for modern PCs with Active Power Factor Correction power supplies. The APC BR1000MS, APC BR1500MS2, and the GOLDENMATE lithium models list pure sine wave output. A smaller basic UPS can still be appropriate for a simple office setup, but sensitive or powerful systems deserve the cleaner waveform.
Runtime
Runtime depends on the connected wattage, not just the UPS capacity label. The APC BE600M1 lists 23 minutes at a 100W load, the BE650G1 lists 29 minutes, the BR1000MS lists 42 minutes, and the larger APC models list more than an hour at 100W. Those figures are useful reference points, but a computer under heavy load will reduce them sharply.
Buy enough capacity to save your work and shut down cleanly, not enough to pretend a UPS is a whole-house generator.
Outlet layout
Count the devices that need battery power, not just the number of plugs on the rear panel. The APC models divide outlets into battery-backed and surge-only groups, while the GOLDENMATE models listed here provide battery backup and surge protection across all eight outlets. Network equipment, external drives, and a monitor may all need battery support if you want the computer to remain useful during an outage.
Battery chemistry and replacement
Traditional lead-acid batteries are replaceable in the APC models, including the BE600M1, BE650G1, BX1500M, BR1000MS, and BR1500MS2. The GOLDENMATE models use LiFePO4 batteries and list long service lives with thousands of charge cycles. Lithium designs can reduce maintenance, but the product's stated runtime and capacity still matter more than chemistry alone.
Voltage management and shutdown control
Automatic voltage regulation corrects brownouts and surges without using battery power for every fluctuation. A communication port can also let a computer or NAS initiate a safe shutdown. That is especially useful for unattended systems. If a desktop stores important files, connect it to the UPS through the appropriate communication cable and configure its shutdown behavior.
For a broader look at the component that feeds power to the computer itself, how to match a supply to the rest of your PC is a useful companion consideration. Cooling also affects the whole system, and how much airflow a desktop really needs can help when placing a UPS near a warm computer.
Frequently asked questions
What size UPS does a gaming PC need?
That depends on the computer's maximum draw, the monitor, and any storage or networking equipment connected to it. A 600W UPS may suit a moderate system, while a powerful gaming PC is better matched with the 800W, 900W, or 1000W models here. Check the system's power requirements and leave headroom for startup and load spikes.
Is pure sine wave important for a PC?
Pure sine wave output is a sensible choice for modern PCs, especially those using Active Power Factor Correction power supplies. It can provide a closer match to utility power than a basic simulated waveform. The APC BR1000MS, APC BR1500MS2, and GOLDENMATE models in this roundup list pure sine wave output.
Can a UPS keep my computer running during a long outage?
It can, but runtime falls as the connected load rises. The listed runtime figures for the APC units are based on a 100W load, so a gaming computer under heavy use will run for much less time. The main purpose is to prevent an abrupt shutdown and give you time to save files or let software shut down safely.
Should the monitor connect to the battery-backed outlets?
Yes, if you need to keep using the computer during an outage. Connect the computer, monitor, router, and essential external storage to battery-backed outlets. Speakers, printers, and other noncritical accessories can use surge-only outlets when the UPS provides them.
Do UPS batteries need replacement?
Lead-acid batteries eventually need replacement, even if the UPS itself remains functional. APC lists user-replaceable batteries for its models in this roundup. The GOLDENMATE units use LiFePO4 batteries and list long service lives, though any battery system should be monitored for warnings, swelling, unusual noise, or other abnormal behavior.
Can I put a UPS in a cabinet?
Only if the cabinet provides adequate ventilation and the product's safety requirements allow it. The GOLDENMATE models use cooling fans that activate during heavy battery usage, and their instructions warn against high-temperature or enclosed environments. Keep the UPS in a clear, dry location with room for airflow.
Can a UPS protect a router and NAS as well as a PC?
Yes, provided the total connected load stays within the watt rating and the devices use the correct outlets. The APC models specifically list routers, modems, external drives, and NAS systems among their intended equipment. A communication connection can also help a compatible NAS shut down safely during an outage.
The bottom line
The Best best ups for pc pick is the APC BR1500MS2 because it combines 900W capacity, pure sine wave output, automatic voltage regulation, a useful LCD, 10 outlets, and USB C charging. It is the model to buy for a demanding desktop, NAS, and full workstation, provided you have room for its heavy chassis.
The GOLDENMATE 1500VA/1000W is the better alternative for someone who wants the highest capacity in a lithium UPS, while the APC BE650G1 is the more sensible choice for a small computer and router. The GOLDENMATE 1000VA/800W models sit between those extremes with pure sine wave output and long-life LiFePO4 batteries.
If you are undecided, choose the smallest model that leaves clear wattage headroom and enough battery-backed outlets for every device you need to shut down safely.
