Right idea, wrong value. 8 ohms on a 5 volt rail will only pass 600mA,
about 3 watts. Generaly PC power supplies need about 30% of the rated load
on the lowest output voltage to produce regulation. The one I have here is
rated for 18 amps on the 5V rail so you would need about a 1 Ohm reistor
(or slightly less) to force it into regulation.

Newer ATX supplies need the draw on the the 3.3 volt rail. 0.5 to 1 ohm
should suffice here.

ATX is easy enough to power up. There should be one green wire, short it to
any black (ground) wire and the supply should power up just fine. (mine
does :o)
