How much PSU wattage would I need for my build?


Oct 22, 2013
Hello. I'm new to the forum and I've read so many stuff about computers in general here. I'd like to ask how mcuh wattag I would need from a PSU for my build?

Intel Core i5 3570 non-k
Cooler Master Hyper 212 Evo
Asrock Z77 Pro3
Gskill Ripjaws X 8GB RAM
Inno3D GTX 760 iChiLL HerculeZ 3000
a cheapo DVD-RW

I was getting inclined to get a 500 watt PSU as my friend suggested, he has almost the same exact components and it has been sufficient for him. The guy at my local PC store said I need 700 watts, I asked him why? I'm not going to SLI, and i'm not going to OC. He can't give me a clear explanation, he just insisted on it. Can you guys help me out? Thanks. :)
