What is the required PSU for a GTX 660 (non TI)?

[bingaloman]

I searched online and at newegg and the EVGA non ti GTX 660 says it recommends a 450W PSU but then when I looked at the Zotac GTX 660 it says it recommends a 600W PSU.

Should all the GTX 660 recommend the same PSU wattage or does the Zotac one just use more power or something?

Thanks!

Depends how power hungry your other parts are too but you can probably run a GTX 660 off a good quality 450W+ unit. A Corsair CX430 may suffice, I run a 7870 off an Antec 520W and I have no problems. Not to mention my CPU guzzles energy compared to a modern Intel.

Yea Im asking about the Zotac GTX 660 though, it says it recommends 600W, where the EVGA GTX 660 says 450W.
Shouldn't they be the same?

A good quality 450W should suffice. You definitely don't need a 600W.
