PSU for graphics

[x2 3600 rules sazakky]

Is it possible to run a normal computer psu and dedicate it to a graphics card. If I did that, how could i make it work and how could I switch on the psu without connecting the psu to a motherboard.

No and yes...
A "normal computer PSU" is switched by the MB, so the answer is no.
Thermaltake makes a dedicated PS for the graphics cards... Power Express 250W, so yes, you can have a dedicated PSU.

you know...this is a really really cool idea. I'd have never thought of that. Although I find it rediculous that video cards need so much dedicated power, I find the prospect of offloading your video crd from your main PSU (so you don't have to fork over the bux for a new one) a very interesting and well thought out idea. This would definately be the end of the question "so I need a new PSU to run my new HD2900XT?" the answer is yes, but only a small $45 unit.

I think you would almost have to go with a specialized PSU like the one Blain linked. I don't know of too many computer cases that have backplane cutouts for two standard PSUs.

There are a few around.

Hmm i have friends who have done this by messing around and "tricking" a regular power supply into thinking its connected to the mobo... I don't know exactly how they did it, but it involved a bunch of jury rigged cables and manually triggering the extra PSU simultaneously with booting the computer.

This should work for what you have in mind.
