Recommended power supply for AMD Radeon HD 7970 ?

post #1 of 13
Thread Starter 
Any recommended Watts for a PSU for use with an AMD Radeon HD 7970?
post #2 of 13
500W is recommended by AMD (http://www.amd.com/us/products/desktop/graphics/7000/7970/Pages/radeon-7970.aspx#2) but if you want to overclock then I'd go for 650W. 850W if you're considering X-fire in the future

^^^ Any high quality 500W-600W PSU will work fine for a single 7970. There's a sticky in the OCN Power Supply forum with specific recommendations. Here is a direct link:

500-600 Watt will be fine, as long as it's a quality unit.

The current PSU that I  am using is http://www.bequiet.com/en/powersupply/251 and the system I want to power with it is http://pcpartpicker.com/p/18vuM.  Would I be able to use this PSU with this system without any problems when the system is under load?

Yes, it'll be more than enough.
