Greetings, I recently built a gaming PC with the following specs: Intel Core i7 3930x extream Gigabyte UD5 LGA 2011 MoBo 24gb DDR3 2 GTX 780's in SLI Corsair H100i cooler Thermaltake Toughpower 1350w PSU Thermaltake full ATX chas. I put this system on a Cyber Power (true sinewave) 600w UPS and to my surprise it shut off on me right when I loaded the video cards with crysis 3. I plan on sending that UPS back to Newegg and purchase the CyberPower 900w unit. My PSU is an active PFC type, so I am very limited in finding a UPS that is over 900w with sinewave tech. that wont break my wallet. My question is, Will the 900w UPS work when my system is at full load? I do not know what I am drawing from the wall at idle. Thanks guys.
