Many PC PSUs (not all) require a base load on the 5V rail to work properly. Connecting an old CD drive or a 12V light bulb (into the 5V rail, see picture) are well proven methods to get this load.
Wether you need a base load or not has to be tried. If even tiny loads on the 12V rail cause the PSU to turn off, a base load is required. Also, a base load never hurts.

Hello Guys. I have sucessfully connected and shut down my atx power supply, but I have one problem: my ramps is powered trough USB and the atx. When I switch off the atx with m81, it turns off, but my Ramps has power trough the USB connection from my PC. the problem is: When I disconnect the USb cable, the atx ist switching on for ~1s, and immediatly switching off and the back on and so on. Until the capacitors in the atx are empty, then it stops. What can i do? Is it because of the pull up?
Thanks!
Dominik
