i keep reading mixed things about PSU's, some people say 600w is enough, 700w is enough for just about anything, and then people saying you need alot more. i want to be able to do moderate to heavy overclocking as well with this build.
a 450W will power this system stock, so I'd shoot for a 650 or 750 if you indeed intend on heavy overclocking. Shoot for a quality PSU over pure wattage. Of the two you have there I'd go antec for the gold efficiency rating
I use the 750W version and I'm very happy with it, it handled a faulty power cord failing at work and a power loss every once in a while due to our amazing florida power surges. EVGA also makes an individually sleeved cable kit which is FANTASTIC if you're not ready to do the sleeving yourself. You can definitely get cheaper ones that will work, but with a 10 year warranty and my personal experience, I wouldn't mind spending a little more for this PSU if I could do it over again.
