Antec. I have had, over the last decade, much better luck with the PSU's I can get for $20-$40 from the importers than I ever had with Antec. Every Antec I ever bought was in the recycle bin by the time the so-called warranty was used up, or within a couple of months later from low voltage output. I have 4 HD's totalling 3.5TB in this system, and the 350 watt hi-pro brand psu in it is at least 2 years old & still running great, and its voltages have not faded a bit in that 2+ years. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
