I'm thinking about building a new computer. My specs will be Core i5 3570K, ASRock
Z77 Extreme4, 4 to 8 gigs of RAM,gtx 560ti and a 500gb hard drive. I'm just wondering how big of a power supply i need. I may in the future run a sli setup with this, so a power supple capable to that and some overclocking as well. Any recomendations on my build will be greatly appreciated!
