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.

If you can see this, you have WAY TOO much time on your hand. Or you're a mod going through my sig. But if you do, copy and past this in your sig.

3amps I believe, I have one here that says 30 amps under +5v and 12 amps under +12v

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