Is it bad for a computer power supply to be switched on without a load?
I know it's possible to start the power supply, i get loads of power
supplies in
from returns but i don't want to chance blowing a mainboard up
(i could hook an old cd rom drive up to put a load on 5 and 12v but
would like to avoid clutter.)

Just build a dummy load with a bunch of resistors or so.
If you connect green and black, an ATX power supply will switch on

That depends on the color of cables the PS maker felt like using.
You should learn where on the power connector those two leads are instead
of relying on the PS maker following a particular color scheme.
