I would prefer to spend in the 100-125 dollar range. Thanks.
Your rig would need more than 550VA. You are looking at 1200VA and above. Actually VA rating is not that important as long as your PSU is modern and supports Active Power Factor Correction (Active PFC). 1200VA and above is usually rated at 700+ Watts.
Let's see, 2600K and 2 x GTX 580, and a 550VA UPS usually only provides ~300 Watts of output. Clearly not enough to power to your rig. Don't forget you need to also factor in some extra wattage for the monitor and for the wattage PSU wasted due to efficiency lost (some extra 40W to 50W).
The UPS you picked won't even last a minute during blackout. You really missed your chance. Back then Newegg did a Black Friday deal with Cyberpower 1350VA 810W for $119.
Furthermore I typically recommend people to get an UPS with pure sinewave output. Some PSUs are very picky and regular UPS won't work with them.
Although I recommend go even higher and get 1500VA 900W version.
So borrow some money.Edited by trumpet-205 - 12/6/11 at 12:18pm
