Would the power supply from my old computer be OK to use for matching Mosfet's? Too noisy ?
Thanks,

what is the specifications? Volts/Amp
I do not think noise is any trouble.
It is not as much noise in them as you might think.

Your PC power supply requires a minimum load to "regulate" the output.
Just buy an Heathkit IP27 on EBay -- more than adequate for the task.

minimum load
Just put a 5ohm 5W resistor across the 5V output and that will take care of the 1A minimum load. The other outputs usually don't have a minimum load. I used a computer power supply with just that resistor for a few years, and It worked great. Now I am building a diy power supply from my SOZ. (I couldn't take the heat so I built a pair of zen's)
The output ground, case and input ground are all tied together so don't try chaining unmodified supplies. (Yes I have stacked these things)
