You'd need an adaptor that links the two purple (I think it's purple at least) wires on the 24pin ATX, so that the second PSU can power on with the first.

You'd also need to make sure that both PSUs have their minimum load placed on all rails (usually about 1-1.5A per rail), which if you are just powering peripheral devices with the second PSU will be tricky to do, as most peripherals only use the 12v rail.

But if these things are taken into consideration, yes, you can link and run two PSUs on the same computer.

PS. If you are doing this with cheap PSUs, I'd strongly recommend not doing this and just buying one decent PSU.

Its the green wires, but here is what you need http://www.frozencpu.com/products/5637/ ... Cable.html

Would suggest the board and video card on one PSU, everything else on the other. This is how the Antec NeoLink is setup

Yes you are right. I am forgetting about doing that and going to buy a TT 500 or 450.
