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 much wattage would I need from a PSU for my build?

specs:
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. :)

Oh, I forgot to mention, I live overseas, so my only options would be the Antec VP550P, EA500 Platinum, Seasonic S and M2II's, Corsair VX and CX 500s, and some Cooler Master Silent Pros and Thermaltake PSUs. Prices @ newegg, ncix, or any other stores in the US won't apply to me, but thanks for mentioning them. :)

your system doesen't require more than 400 watt tpd on super extreme power consumtion i added more watt when calculating just incase.
dont go with more than 550.
he did nothave a clear explanation because a good 700 watt costs nearly twice the money than a 500 watt.and he is probbly unexpirienced.your friend sudgested good ;)

Of the ones you mentioned, I'd go for the Seasonic. But all you need is 500W, the guy who says you need 700W is just plain wrong.
