Default 2 PSU's in a single PC (is it possible?)

Hi,

I just had a wierd thought and since I dont know much about this subject I thought I should ask some people.

Is there any reason why not to use 2 PSU's in a single PC with one running almost the whole system and the other just connected to the graphics card(s) only?

It would seriously cut down prices if I only need to buy a small extra PSU rather than a huge one if this would work.

Hey tedstokes,
Welcome to T.F.!

Yes, it's possible. But it's unnecessary like vernong said. You're better off buying one, that will handle everything in your system, which isn't very expensive. What PSUs were you thinking of buying? IMO, this PSU should run mostly everything with no problems:

very bad idea, depending on the card.

when I did it with my 79GT, the 2nd PSU powered stuff on the motherboard though the PCI-E bus if the main PSU was off and the 2nd one on. This can damage your graphics card because of excess current being pulled through the traces.

I heard that the X1900s were OK with it, but I still wouldn't do it again.

If you really want dual PSUs, use one to power the opticals, HDDs, fans etc, and the other to power CPU, mobo, GPU.

I think the Thermaltake Mozart tx and the stacker have mounting spots for two PSU's. Thermaltake also makes Smaller PSU's that fits into a CD drive bay that I are designed to just power Graphics cards.

If you want something just power a graphics card safely and reliably, then this is it.
