What is a good brand of power supply unit?

I have seen several, Logisys, Thermaltake, Enermax to name a few.

Money is an issue. 

ThanksHow many watts ?
How many dollars ?I suppose in the 500 - 600 watt range.

Maybe $30.00 - $50.00.

I have seen these brands new, on eBay for this dollar amount.

Of course the Logisys was cheaper than that.

I just want something reliable.

Thanksyou will not find any reliable brand name brand PSU's 500-600W for $50. however, if you do find a deal on ebay, look for corsair, OCZ, or thermaltake. the cheapest brand PSU i would get would be earthwatts, antec's brand of PSU's. there is nothing special about them but apparently they are QUITE reliable.

personally, i would get a corsair, but they do tend to be a bit on the more expensive side.Thanks, there seems to be several Thermaltakes on eBay.Try MicroCenter's online store...
They have the OCZ StealthStream 500W on sale this month for $50 BUCKS...reliable and quiet.
I have used these in the PAST 3 builds i've done and grabbed a SPARE one for inventory...
