I'm making a Youtube video for one of my viewers for building his $500 budget gaming build. consisting of an i3-3220 and Radeon 7770. I'm trying to choose between 2 equally priced power supplies and not sure which one to choose? The Corsair VS-450 is 450W and has a single 12V rail with 33A. The Antec VP-450 has dual 12V rails with 18A on each... don't know? To my understanding, I should be looking at a single 12V with the highest amperage... but I could be wrong?
