Hi my current 750w PSU fan is dying, the PSU fan sometimes stops and shuts down my system due to it overheating. I believe my current wattage of the PSU is a little too much for my system and I could do with a lower wattage PSU.

My budget is 55 dollars or under.

Thanks.

1055t Phenom 2
8 GB DDR3 RAM
HD5770 Radeon
2 Case Fans
2 Optical drives
2x 1TB 7200 RPM harddisks
case lighting.

Overkill wattage on a psu will not make a difference... however, underwattage will. Sometimes, PSU's die... it is a simple fact ... If you are going to buy a new psu, check into rosewill psu's they are a quality power unit that will fit a budget. Like this one for starters

With that system, you could make do with a good 500 no problem. Maybe even a 400. My quad-core QX9650 overclocked from 3.0 to 3.8GHz, northbridge overclocked from 333 to 380, and GTX 580 overclocked to 1100mV, 900/2340 only pulls 460 from the wall at full GPU and CPU load (Prime95 and Furmark), which means the components are only getting 420ish. 400 should do you fine, I would imagine.

55 bucks is a strict limit though. You can get a Corsair Builder series 430 for under $50 right now, and I don't know too much about that particular PSU line.

Should be a decent power supply, but you might want to wait for some experts to chime in before you make any decisions.

Excellent choice.

400w is plenty; just make sure it's a quality unit (like this one).
