Many of the cheapo PSU's 'rate' their wattage much higher than they can actually sustain. When I built my dev machine at work, I used a cheapo 750watt PSU that we stock for replacements on customer machines. I burned out 3 or 4 of those before deciding that the swap time and associated hassle justified buying a good one. I've had excellent luck with both thermaltake and antec PSU's and the new 80plus certified PSU's run really cool and quite (a nice side effect).
