Solved Is current PSU not enough? Tags: Power Supplies Components Last response: August 24, 2012 11:49 PM in Components Share CoderX71 August 19, 2012 11:21:36 PM Hi All, Recently I built the following system, some parts were from my previous build namely HDD, Case and PSU. New Parts: Intel Core i7 3930K G.Skill 16GB (4x4GB) DDR3 Kit, PC-12800 (1600Mhz), RipjawsZ, 9-9-9-24-2N Asus Rampage IV Formula, X79 Gigabyte 7970 3GB x 2 (Crossfired) Cat 12.8 3 x 23” Samsung LCDs (5760x1080) Existing Parts: 2 x WD 500GB HDD 1 x OCZ Agility 3 120GB 1 x OCZ Agility 3 240GB Thermal Take tough power 850W Raven II case OS Win 7 64bit Pro Now the the issue I have is the system locks during gaming, usually after about 15 min or so. I can't even use the reset boutton on the case, I have to physically cut the power. With general apps like Firefox for example I'm getting corruptions in the text and then a black viewing area, with IE9 I'm only getting corrupted text. With 2 x HDDs, 2 x SSDs, 2 x 7970s and 4 x 120 fans running, do I need beefier PSU?

My guess is that it's a driver issue. Failing that, possibly one or both of the GPU's themselves is faulty (or dying, even if they are new). m 0 l dudewitbow a b ) Power supply August 19, 2012 11:43:07 PM did you do a clean install of windows when you transfered the storage over? m 0 l Related resources Will my current PSU be enough for my new system? - Forum Is my PSU big enough? - Forum System Freezing - Forum Rampage III System Build Input Wanted - Forum Help me modify my new system - Forum Can't find your answer ?
