UPS for a gaming computer - unsure on where to start

Hi all,

I am looking to purchase a UPS for my gaming computer to combat the weekly brownouts in my area. I am unsure on where to start looking and how to select the proper UPS for my needs. Below are some of the specs for the PC:

Intel Core i7-3770K - not overclocked
MSI GTX 580 Lightning Xtreme - not overclocked
ASUS P8Z77-I Deluxe
Corsair AX750 PSU
1 23 inch LED monitor

I am not looking to run this computer on battery when the power goes out, I would just like to prevent the computer from shutting down during brownouts. If there is an extended period of no power, I will shut the computer down and wait for the power to return.

Thanks for any advice and possible recommendations on some specific units that I should take a look at.

Based on your system configuration this one should give you around 6 minutes of battery runtime if your system is in full use at the time of a power interruption event. It has automatic voltage regulation to handle voltage sags or spikes. You'll need a pure sine wave UPS that can properly handle the Corsair AX750's active PFC circuit. X-bit labs tested the Corsair AX750 on a UPS that outputs a simulated sine wave and the UPS would not switch over to battery operating mode during a power interruption event.

Thanks for the replies guys. I've read those articles Jack, they were very helpful. I also did a little investigation work and discovered that those CyberPower units do not actually output a pure sine wave, even though they say that they do.

I've limited my search down to two UPS units now:


I am kind of hesitant to purchase the SMC1000 because it only has an output of 600 watts. I know that my computer does not use that much wattage during full load but the difference between the two units is only 90 dollars.

What do you guys think?

Either of them will be fine!

Thanks for the replies guys, I've spoken with several representatives from APC and they all recommend the SMC1000 as the most cost efficient choice and the SMC1500 as the optimal choice. I believe that I will purchase the SMC1500 just in case I decide to upgrade my computer down the line or add anything else to the UPS.
