power trips


Not in the psychological sense..



Well I have this power suppy, dvd-rom, hard disk, graphics card and motherboard all out of the chassis sitting on a piece of cardboard. The problem was that after a few seconds of turning the pc on the electricity supply would just trip. To get it going again I'd have to unplug and replug in the power cable.



I tried changing the graphics card and ram - no difference.

I tried another HD and dvd-rom and this time the power cuts only if the HD is plugged in with the dvd-rom, but seemed to work fine if just the dvd-rom was plugged in.. logically that seems like a problem with the power supply as though it can't take the HD as well as the dvd-rom, but that's new too.



I tried a sata HD but I just cannot get that to be recognised, and like I said the IDE hd just trips the power sup..



Any ideas? I hope it isn't the motherboard or cpu...



Thanks in advance.

+12V@12A is very low for a modern PSU. Sounds like it's time for a more powerful one.
