I placed an order for XFX 7950 Doubld D(not black edition) but I am getting some varying information on the PSU requirement. The GPU manufacturer is stating minimum of 500 watts but some review sites are recommending 700+ watts. My PSU is Seasonic 620 watts.
Here's my complete system set up:
CPU: i5-3570k overclocked to 4.4Ghz
Cooler: Hyper 212 EVO, single fan
Mobo: Gigabyte z77x-D3H
RAM: Crucial 8GB(2 sticks) 1600 DDR3 CL8
Case: Antec One. 5x 120mm case fans. No case lights. 1 DVD-RW drive. 1 PCI wireless card.
Hard drive 1: Crucial M4 128GB SSD
Hard drive 2: Seagate Barracuda 7200RPM 2TB
GPU: XFX Double D FX-795A-TDFC Radeon HD 7950 3GB
PSU: SeaSonic M12II 620 Bronze 620W
I do plan on overclocking the 7950.
Does my PSU have enough power for all this?
