That was certainly one of the better links of modding PC supply for bench use.
I like the fact that he shows you can get Voltages other than 5/12/3.3 etc by using the differences between pos & neg voltages...nice one.

I've used many PC supplies over the years for a quick resource for +5v/+12v at several amps with no probs.

I NEVER found a need to provide a load-resistor, as my electronics being powered was enough load.
I can see the advantage that running a few I.C's on a protoboard might require the power-resistor to load the switchmode into operation.

With the ever falling price of PC supplies, 2nd hand or NEW this is a handy project for the pinny-hobbyist.

Cool stuff !
