I'm building a pc, which includes a radeon 7870. The manufacturer recomends a 500w, but the psu calc on Cooler Master recomends just over 350 watt. I was going to buy a 430watt, because that's the cheapest modular one I can find.
My parts:
AMD A10-6800K
MSI FM2-A75IA-E53
Crucial Sport 8gb 1866
Sapphire Radeon HD 7870 GHZ edition
1 WD blue hard drive, 1tb
Some slop of a dvd/cd drive
Cooler Master gemini slim cooler thing...(forgot the exact parts #)
Cooler Master Elite 120
(AND I DON'T WANT ANY FRIGGEN CRAP ABOUT USING THE A10!)
