No.

A "good one" is a PSU with adequate power for your particular requirements, from a reliable manufacturer.

You can all finds of lousy PSUs that have good specifications on the label. The specs for those PSUs mean very little because you don't know if the specs are true. And even if "true", under what circumstances were they measured? 840 watts for 10 seconds, then fails? 840 watts in a highly refrigerated room?

And you need to pay attention to TOTAL power. A PSU that has two 12 volt rails at 35 amps each may be able to supply only 700 watts total at any time.

i purchased the corsair h60 and my cpu temp has not gone over 53C, I've had less crashes, but a few still linger around. I've chosen the Seasonic X750 Gold, its at least 100 w over my required. I'm ordering it next monday

Just a heads up. I noticed we were having PSUs die on us fairly regularly and the culprit eventually was traced to an unstable (?) wall socket. What clued us in was the bulbs for the light on the wall the socket was on seemed to flicker randomly and also kept dying and needing to be replaced in very often (3-4 months per bulb). Moved the computer to a different outlet, hey presto, no more problems. Bad wiring I guess.

Yeah I've had that issue in an older house I lived in, our apts were built like 3 years ago so that's ruled out. I did get my psu installed yesterday, it finally arrived I've come the conclusion I need a bigger case though, but it all fits and so far so good, 2 days no bsod.
