But my question is. Is a 800 wattage power supply enough for CrossFireX HD 7970? Some people say HD 7970 will use 249W at full load. So ~500W for CrossFireX right?
I've tried to find a Power Supply calculator but I couldn't find one on the internet. So I thought. Let's ask the awesome people at Tomshardware - So. Should 800W (Cooler Master Silent Pro Gold 800W, 80 PLUS Gold) be enough for:
Okay, So this one should be good for the 2 HD7970 in Crossfire?
I can also get the: COOLER MASTER Silent Pro Gold Series RSA00-80GAD3-US 1000W ATX 12V v2.3 / EPS 12V v2.92 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply - http://www.newegg.com/Product/Product.aspx?Item=N82E168... for even less money (and it's 80 GOLD too)
