Hey guys. I've tried researching about getting into using an SFX12V PSU for my next build:

I had the Silverstone ST45SF-G 450W Gold Rating 80 PLUS: The manufacturer states it has 37A available on the 12V Rail.

While researching the required amps needed for top tier graphic solutions, such as GTX 770 and HD 79X0 cards, I saw that GTX 770, HD 79X0 cards need 42 A, 25-31 A respectively.

If I plan to OC an i5 4670K to 4.5GHz, what is the best card that will not run over this PSU's 37A rating?

Else, if I do't OC the i5 4670K, what would be my best option then?

Any help is appreciated!
