Hey guys, this will be my first upgrade for my pre-built gaming desktop. I have looked around online (specifically Amazon bc I have a gift card) and am considering these two. I am on a budget and am just confused with this talk of "pins" when it comes to a psu, and the extra voltage and such. I think my cpu is sufficient being a i5-3350p. so here are thoughts. I would be grateful to hear yours.
