Cheapest PSU for AMD FX-8350 and AMD Radeon HD 7970? With KILL-A-WATT the wattage was roughly 600W (580W-595W)

with FurMark and Prime95 running at the same time). Would Corsair TX650W or XFX PRO 650W be enough? What's better? I'm

not a PSU Guru so I don't know which to choose or if it will be good enough. I will play Battlefield 4 in the future. The rest of my

specs will be:

ASUS M5A97 R2.0

AMD FX-8350 4.0GHz

Corsair Vengeance Blue 2×4GB DDR3 1600MHz

Sapphire Radeon HD 7970 3GB GDDR5 Boost Edition

Zalman Z5 Plus

Western Digital Caviar Blue 1TB

I won't overclock anything, the system draws 580W-595W when AMD FX-8350 is manually overclocked to 4.2GHz, so I should

expect 550W power draw? (If that's true, I will buy a Seasonic S12II 620W instead of a more expensive TX650W or XFX650W.

The Seasonic 620W PSU is easily enough for your setup. You shouldn't need to upgrade to another PSU.

Seasonic S12II 620W and Corsair Builder Series CX750W are at the same price at my place, shouldn't Corsair Builder Series be better?
