Once you’ve spent the time and resources to build a worthy gaming machine, you’ll want to protect your investment any way you can. Eaton’s 3105 UPS is a good place to start.

The 3105 has four outlets with battery backup plus surge protection and four additional outlets with surge protection only. On the side are two telephone line plugs. The small design makes the 3105 ideal for placement under a desk, though it can also be wall-mounted. This UPS features a series of alarms that alert you of the UPS’ status, such as low battery or overload.

We tested the 3105’s 700VA model, which is rated at a capacity of 420W. We monitored the wattage our machine pulled and simulated a power outage by unplugging the UPS and recording the amount of time the battery backup kept the system running.

During light use (browsing the Internet, listening to music, and losing at a game of solitaire), our test machine pulled approximately 320W. When the power went out, the 3105 was able to keep our system running for 7:18 (minutes:seconds), which was plenty of time to save work and shut down the computer properly. Under heavy use (shooting innocent sea animals in Crysis), our test machine pulled 85Wmore than the 3105’s rated limit. At full capacity, Eaton states that the 700VA model will last a maximum of three minutes, and in our overloaded test, the UPS was able to run our game for 2:01.

Even under a heavy load, the 3105 UPS was a tough performer. And with the reassurance that the included surge protection offers, this UPS is a must-have if you’re serious about protecting your most prized possession.
