So I have the Ultra LSP 650w Power Supply, I'm fairly certain that it meets the requirements for both the i5 4670k, and the ASUS GTX 770 but I'm concerned with the single rail only putting out 38A. It has both the 6 and 8 pin requirements, but I feel like I'm missing something.
Should I be concerned and upgrade to something else? Or am I being paranoid?
Ya, the unit you have only has 38 amps on the 12v. I would go with something over 50 imo. Like smorizio said go with Corsair. They have decent prices and good units. The one he linked is not bad at all.
