Using 2 PSU on 1 computer ( Second PSU turns itself off when under load)

6

I have followed the guides on the internet, in short to start the second PSU short the green wire on P1 with a black ground wire and the PSU will start.

This works, my second PSU does start. But if i attach any harddrives to it it turns itself off after 1-2 seconds. If i only connect fans or nothing it will remain running.

If it mathers the PSU is from colermaster. They're both ATX powersupplies, and i have tried to use 2 different ( But same brand/model) PSU as the second PSU.

4My quick recommendation would be to avoid all of this by buying a much larger single power supply. – Troggy – 2010-07-13T17:46:55.387

Instead of just jumping it out, you could try this adapter cable.

2It shutting off under load sounds like a loose connection or bad PSU to me. I have this configuration working at my house. – RobotHumans – 2011-06-27T18:34:25.387
