Is my PSU big enough? Tags: Power Supplies Components Last response: August 21, 2012 11:36 PM in Components Share CoderX71 August 19, 2012 11:10:04 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 LCD monitors (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 HDDs, 2 SSDs, 2 7970s and 4 120 fans running, do I need beefier PSU? More about : psu big jemm a b ) Power supply August 20, 2012 12:48:36 AM Unless your PSU is faulty it is enough. What are the temps while playing games? m 0 l clutchc a c 152 ) Power supply August 20, 2012 2:05:00 AM Although I prefer single rail PSUs, there is nothing wrong with that PSU powering a pair of 7970s. You should have room to spare... depending on what other power hungry components you have in the system. http://www.thermaltake.outervision.com/ m 0 l Can't find your answer ? Ask !
