There are a lot of choices, even lower priced ATX power supplies like the Sparkle brand will last years. You would be hard pressed to find one that won't last a couple of years at least.
Now you want to go high end get something like a Power and Cooling supply from http://www.pcpowercooling.com/
Does anyone have a reccomendation for a good 450W ATX power supply, I blew mine and am wondering if anyone has any ideas on a good quality PSU over a cheap one that will last for about 2 weeks and then blow up.
