Is this Power Supply enough for my specs?

Is my Hyper 580 enough for my setup, I'm only asking because my pc locks up when booting up at the Asus logo or Windows bar loading screen. I have tried different stuff and I just wanna make sure that my power suppy is not the problem. Like I said I have tried different things and my pc would work for a few days and it would start locking up again. It's not a temp issue cause I have a very good case with 5 case fans with the A/C in the house running most of the time. My temps average from 32-38c, plus my system is not overclocked, except for my video card which came factory overclocked. As of now I use my pc and when it locks up I make a change in bios (ram timings, voltage, etc) or I'll turn it off, unplug power and turn on again. I have the most recent bios update for my motherboard, I've reset bios, checked connections, ran memtest and other utilities. I've set everything in Bios to Auto and also tried manually but so far - can't figure out what the problem is. I tried another memory but always wondered what if the problem is my power suppy. What do you guys think?
