The best uninterruptible power supply for most gaming PCs in this group is the GOLDENMATE 1000VA/800W Lithium UPS, because its listing pairs a pure sine wave output with a 230Wh LiFePO4 battery, eight outlets and a color LCD, which suits modern power supplies with active power factor correction. A UPS, or uninterruptible power supply, is a battery box that keeps your PC running for a few minutes during a blackout so you can save and shut down safely. If your rig draws a lot of power, the 1500VA models from APC and Vertiv offer more headroom, while the 600VA and 650VA APC units are only meant for modest systems, routers and consoles.

Which One Is Right for You?
| If you… | Choose |
|---|---|
| own a power supply with active PFC and want a pure sine wave on battery | GOLDENMATE 1000VA/800W Lithium (White) |
| want the same lithium unit to blend in with a dark desk | GOLDENMATE 1000VA/800W Lithium (Gray) |
| run a mid-to-high-end gaming tower plus monitor and need extra headroom | APC BX1500M 1500VA/900W |
| prefer a line-interactive 1500VA unit with AVR and user-replaceable batteries | Vertiv Liebert PowerUPS 200 PSA6E-1500LVT |
| only need to keep a modem, router and a small PC or console alive | APC BE600M1 600VA/330W |
| run a basic office PC or NAS that draws little power | APC BE650G1 650VA/390W |
Three numbers decide the choice: how many watts your equipment draws, what waveform the UPS makes on battery, and how long you need it to run. Add up the watts first. The VA figure is the apparent power figure, and the watt figure is the usable power, so always check the wattage against your real load. A UPS is meant to give you a few minutes to save work and shut down, not to extend a gaming session through an outage.

View on AmazonAll 6 Picks in Detail
1. APC BX1500M 1500VA/900W – Best for a Mainstream Gaming Tower
As an Amazon Associate we earn from qualifying purchases at no extra cost to you.
The APC BX1500M listing describes a 1500VA, 900W battery backup and surge protector with 10 outlets and a 789 joule surge figure. That 900W capacity gives room for a gaming tower, a monitor or two, and networking gear. APC’s own specifications and retailer pages describe it as a line-interactive unit with automatic voltage regulation and a simulated sine wave output on battery. Simulated sine wave is fine for most devices, but a small number of power supplies with active PFC may react poorly to it, so check your PSU’s documentation if you own one. The battery is a sealed lead-acid type that APC lists as replaceable.
- Capacity: 1500VA/900W, per the listing
- Outlets: 10, per the listing; the split between battery-backed and surge-only outlets: confirm on listing
- Surge protection: 789 joules, per the listing
- Waveform on battery: simulated sine wave per retailer specifications; confirm on listing
- Battery: sealed lead-acid, replaceable; runtime depends on load, confirm on the runtime chart
Pros:
- Large wattage headroom for gaming PCs
- Plenty of outlets for peripherals
- Replaceable battery extends service life
Cons:
- Simulated sine wave may not suit every active PFC power supply
- Heavy and deep for a small desk
Compared with the Vertiv 1500VA unit, it offers two more outlets, a higher wattage figure in the listing and a stated surge figure, so the Vertiv’s appeal rests mainly on its brand, AVR design and warranty terms rather than on raw capacity. If you pick this unit, plug the PC and monitor into the battery-backed outlets, keep the printer and speakers for the surge-only outlets, and connect the USB cable so Windows can shut the PC down automatically.
2. APC BE600M1 600VA/330W – Best for Networking Gear and Light Loads
This APC unit is rated 600VA/330W, with a 490 joule surge figure and USB charging ports, and the listing points to computers, routers and NAS devices as typical loads. At 330W, it is a poor match for a modern gaming tower with a powerful graphics card, because the PC alone can draw more than that under load. Where it fits is a modem and router that must stay online, a small-form-factor PC, a console or a work laptop. Treat it as light-duty protection and read the wattage limit before you plug in anything big.
- Capacity: 600VA/330W, per the listing
- Surge protection: 490 joules, per the listing
- USB: charging ports, per the listing
- Outlets: count and battery/surge split not in the visible title, confirm on listing
- Waveform on battery: confirm on listing
Pros:
- Compact enough for a shelf or desk corner
- USB charging ports are handy for phones
- Good fit for network equipment
Cons:
- 330W is too low for most gaming desktops
- Short runtime when loaded near its limit
It sits one step below the BE650G1 in this list on wattage, so it is only the better pick when you value the USB charging ports and a smaller body. Because it is small, it also works well as a dedicated unit for the network closet, keeping a modem and router online so you can still reach online services or save a cloud game when only the PC loses power.
3. Vertiv Liebert PowerUPS 200 PSA6E-1500LVT – Best for a 1500VA Line-Interactive Unit
Vertiv lists this model as a 1500VA, 850W line-interactive UPS with AVR, eight outlets and USB. Vertiv’s specification pages describe it as an Essential model in the PowerUPS 200 series, with a user-replaceable lead-acid battery, LED indicators in place of an LCD and a simulated sine wave. AVR, or automatic voltage regulation, corrects low or high mains voltage without switching to the battery, which saves battery wear during brownouts. At 850W, it covers a mid-range gaming tower and a monitor, with less spare capacity than the 900W APC.
- Capacity: 1500VA/850W, per the listing
- Topology: line interactive with AVR, per the listing
- Outlets: 8, per the listing; the battery-backed count is listed by the maker as six, confirm on the product page
- Battery: user-replaceable lead-acid per maker pages; confirm on listing
- Display: LED indicators on Essential models; confirm on listing
Pros:
- AVR handles brownouts without draining the battery
- User-replaceable battery
- Professional-grade brand in the UPS market
Cons:
- Simulated sine wave on battery
- Fewer battery-backed outlets than total outlets
Next to the APC BX1500M, it has a slightly lower wattage and fewer outlets, so it is the pick for people who prefer the brand or its warranty terms. Read the maker’s runtime chart for your load, since the published figures differ between retailers, and note that Essential models use LED indicators rather than a color screen.
4. GOLDENMATE 1000VA/800W Lithium (White) – Best for Pure Sine Wave and Long Battery Life
The GOLDENMATE listing describes a 1000VA/800W lithium UPS and surge protector with pure sine wave output, eight outlets, a color LCD and a 230Wh LiFePO4 backup battery. Pure sine wave is the cleanest waveform, and it is the safest choice for power supplies with active PFC. LiFePO4, or lithium iron phosphate, batteries generally last more charge cycles than sealed lead-acid batteries and weigh less. The 230Wh capacity is modest, so expect a few minutes at heavy load rather than a long outage ride-through. This is the version in white.
- Capacity: 1000VA/800W, per the listing
- Waveform: pure sine wave, per the listing
- Battery: 230Wh LiFePO4, per the listing
- Outlets: 8, per the listing
- Display: color LCD, per the listing
Pros:
- Pure sine wave suits sensitive power supplies
- Lithium battery has a long cycle life
- LCD shows load and status
Cons:
- 230Wh limits runtime at high loads
- Battery replacement options and availability: confirm on listing
Compared with the APC BX1500M, it has less wattage but a cleaner waveform and a longer-lived battery chemistry, which is the trade this pick represents. Lithium units also tend to be lighter than lead-acid boxes of similar capacity, which makes them easier to place on a shelf or under a desk, but confirm the weight and dimensions on the product page.
5. GOLDENMATE 1000VA/800W Lithium (Gray) – Best for the Same Design in Gray
This listing is the gray version of the same GOLDENMATE lithium UPS: 1000VA/800W, pure sine wave, eight outlets, a color LCD and a 230Wh LiFePO4 battery. Nothing in the visible title distinguishes it from the white model apart from the color, so the specifications and advice are the same. A gray finish tends to blend with dark desks, monitors and cases, which is the only reason to choose it over the white one. Confirm the model number on both pages to be sure they match before ordering.
- Capacity: 1000VA/800W, per the listing
- Waveform: pure sine wave, per the listing
- Battery: 230Wh LiFePO4, per the listing
- Outlets: 8, per the listing
- Color: gray
Pros:
- Pure sine wave output
- Lithium battery chemistry
- Color suits gaming setups
Cons:
- Same limited runtime as its twin
- Wattage may not cover a high-end graphics card build
It is identical in design to the white model, so choose by color and whichever listing is easier to buy. If you plan to buy two units, for instance one for the PC and one for networking equipment, mixing colors changes nothing about performance.
6. APC BE650G1 650VA/390W – Best for Light PC Loads and Office Gear
The APC BE650G1 is a 650VA/390W battery backup with surge protection, aimed at PCs, office electronics and NAS devices. It is a step up from the 600VA model, but 390W is still modest. It makes sense for a router, a modem, a NAS and a low-power PC, or a small console setup. For a gaming PC with a high-end graphics card, it would likely be overloaded, so use it only if your measured draw is well below its limit.
- Capacity: 650VA/390W, per the listing
- Use cases: PC, office electronics and NAS, per the listing
- Surge protection: included; joule figure not in the visible title, confirm on listing
- Outlets: count not in the visible title, confirm on listing
- Waveform on battery: confirm on listing
Pros:
- Compact class of protection
- Suits network gear and NAS devices
- Well-known brand
Cons:
- Wattage is too low for most gaming desktops
- Short runtime near its limit
Compared with the BE600M1, it adds roughly 60W of capacity but drops the USB charging ports named in the other listing. It is also a reasonable second unit for a streaming or capture PC that sits beside a main rig, as long as the combined load stays comfortably under 390W.

How We Chose These
This guide is built from research into listing details and maker documentation. We started with the six UPS models in the current catalog set and read each listing title and specification field for VA and watt figures, outlet count, surge protection, battery type and waveform. We then checked maker and retailer specification pages for APC and Vertiv to understand the topology, waveform and battery details, and we flagged details that differ between sources. We favored models whose wattage fits a gaming PC, whose waveform suits modern power supplies, and whose listing states clear numbers. Where a detail was missing, we ask you to confirm it on the product page.
What to Look For
Watts, VA and sizing for a gaming PC
Every UPS shows two ratings: volt-amps (VA) and watts. Watts are what count for sizing. Add up the maximum draw of the PC, monitor and anything else you plug into the battery outlets, then keep the total below about 80 percent of the UPS wattage so the unit is not running at its limit. A gaming tower with a high-end graphics card can draw several hundred watts under load, so a 330W or 390W unit is easy to overload. Your power supply’s wattage label is the maximum it can deliver, not what it draws all the time, so a 750W supply in a mid-range build often draws far less. A plug-in power meter gives the most reliable number.
Simulated versus pure sine wave
When the grid fails, a UPS creates AC power from its battery. A pure sine wave output is a smooth curve that matches utility power. A simulated, or stepped, sine wave is cheaper to make and works for most electronics, but some power supplies with active power factor correction may buzz, reset or shut off on it. APC’s retailer specifications list the BX1500M as simulated sine wave, and Vertiv’s pages list the PSA6E-1500LVT the same way. The GOLDENMATE listing advertises pure sine wave. If your PSU maker recommends pure sine wave, or you own a premium PSU, treat that as a deciding factor.
Topology, AVR and battery type
Line-interactive UPS units, like the APC BX1500M and the Vertiv model, include AVR, which boosts or trims the voltage to correct sags and surges without using the battery. That extends battery life in areas with unstable power. Battery chemistry matters too. Sealed lead-acid batteries are common and replaceable, but they usually need replacing every three to five years. LiFePO4 batteries can last more charge cycles, and weigh less, but they cost more and may not be user-replaceable. Check how the maker handles replacement.
Runtime, outlets and safety
Runtime depends on the load and the battery size. As a rough rule, battery watt-hours divided by load in watts gives the hours before efficiency losses, so a 230Wh battery supporting a 300W load lasts well under an hour in theory and less in practice. Use the manufacturer’s runtime chart. Plug the PC and monitor into the battery-backed outlets and printers into surge-only outlets, and never plug a laser printer or space heater into a battery outlet. Do not daisy-chain a power strip or another UPS into the unit. Keep vents clear, avoid hot enclosed spaces, and stop using a UPS that smells hot, swells or shows a fault light.
USB monitoring and automatic shutdown
Most UPS units include a USB data port, separate from any charging ports, that lets the PC read battery status. Windows can use it to start a shutdown when the battery runs low, and maker software adds event logs and alerts. Set the shutdown threshold so the PC closes games and saves files while plenty of charge remains, rather than waiting for the last minute. Check the setup by pulling the wall plug briefly, with your work saved, and watch that the PC stays on and the warning appears. Also set a reminder to repeat the check every few months, since batteries lose capacity gradually and a unit that once gave ten minutes may later give much less.
Worked example
Say your PC draws about 450W while gaming and your monitor draws 40W, so the total is roughly 490W. At 80 percent loading, you need a UPS rated at least 610W. A 900W or 800W unit has comfortable headroom, while a 390W unit would trip into overload. Connect the UPS to your PC with the USB cable and enable the shutdown setting in Windows so the PC saves and powers down on its own after a few minutes of outage.
Questions
Do I need a UPS for a gaming PC?
It is not required, but a UPS protects against brief power loss and voltage swings that can corrupt files or interrupt a save. It gives you time to shut down cleanly rather than losing work.
How long will a UPS run my PC during an outage?
Usually only a few minutes at heavy load, longer at light load. The goal is a clean shutdown, not continued gameplay, so check the runtime chart for the wattage you actually draw.
Is simulated sine wave safe for my power supply?
Many power supplies run fine on it, but some active PFC models can misbehave. Check your power supply’s manual or choose a pure sine wave UPS if you want to avoid the question.
What does the joule figure mean?
Joules measure how much surge energy the protection circuit can absorb before it wears out. A higher number generally suggests more capacity, but it is only one part of protection quality.
How often should I replace the battery?
Sealed lead-acid batteries typically last about three to five years, depending on heat and use. Replace the battery when the UPS reports a fault or the runtime drops sharply. Follow the maker’s instructions for safe replacement and recycling.
Can I plug a laser printer into a UPS?
It is best not to. Laser printers draw large bursts of power that can overload a UPS. Use a surge-only outlet if one is available, or plug the printer into a separate surge protector.
