I just built my PC and I was wondering if my PSU is dangerously low in terms of wattage to support to SLI GTX 580's.
ASUS MAXIMUS IV EXTREME P67 Mobo
i7 2600K OC @ 5.0Ghz
8GB DDR3 1600Mhz Ram
OCZ 240GB SATA III SSD
WD 2TB 7200RPM SATA III HDD
SONY CD/DVD Reader/Writer
ZALMAN 165mm CPU Cooler 2x ZOTAC AMP! 1.5GB GTX 580 OC'd Clock/Shader Clock COOLER MASTER Silent Pro RS850-AMBAJ3-US 850W ATX12V v2.3 / EPS12V v2.92 SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Do I have to upgrade to 1000W to support the above requirements?
