Using a Computer PSU without a computer

connect a 2A load on the 5v leads
Hello, I'm wanting to use a computer PSU as a PSU. The one I've just bought doesn't work. I'm assuming that's because it needs a computer. So.... what does the motherboard do, maybe connects the grey to the green, or the purple to ground, or...does anyone know please??

Easy, jumper the green wire to ground to start the SMPS. Since you have no power good signal coming back, the jumper will have to stay as long as you need the supply on. You also must pull some minimum current from the supply for it to achieve regulation. 2 amps should do nicely
Thanks very much. Power supply working fine.

I sincerly hope you're not a bomb technician (just joking ~:-).
