Re: COMPUSA 250 watt ATX power supply
Pretty cool.

On you next mod consider this.
If you double the silicon [not by capacity, but by component count] you reduce the TOTAL heat loss [dissipation] by something like 2/3-3/4.
What I mean is:
If you have some diode w/10 amps going through it at it's disipating 20 watts....
Two of them in parallel passing the 5 amps each [still 10 amps total] will dissipate something like 4 watts each [8 watts total].
Works similar for rectifiers and mosfets.
That little trick is how PSUs like the FSP Epsilon 700FX [I think you've seen one] can get away with such small heatsinks.
