750w PSU enough for SLI 770's

[Moethedirt]

I am thinking of getting a used 770 for a new pc I'm building. The other specs will be:
I5 3570K
8GB Corsair Vengance1600MHZ Asus P8Z77 V-LK
Western Digital Caviar Blue 1TB
EVGA 750W Supernova.
Xigamatek-Gaia
Haf 912

So If I get the 3570k (All this is used) to 4.2-4.5 Ghz would 750W be enough for another 770 say in a year.

Should be more than enough.

I would definitely use this calculator:

This will help you determine whether you need a better power supply. Personally for 2 770s I like to play it safe and get a 1000w power supply just so you have plenty of overhead. However I think you may be able to get away with 750w if it is bronze certified efficiency or better

850W is a better bet for 2 - 770's.

I have 2 770s and I'd reccomend 850w where you're overclocking.
