Dual PSU setup

post #1 of 5
Thread Starter 
Okay, at the moment I am using a 400W, 28A->5V, 15A->12V, to power an i5-2500K, one HDD, and the motherboard.

I have a 6870 HAWK, but I'm sure it wont work on the above supply (its a generic OEM one, my GS500 died). Im thinking of using my other PSU to power the 6870 via it's molex connectors.

The PSU for the GPU is 300W, 15A on the 12V rail.

Would it work?

And no, I can't 'get a new one' :/

Thanks! biggrin.gif

It'd work, but it'd be kind of complicated. You'd have to do the paperclip trick to make the second power supply do anything

You could do it for the short term, but I would get a bigger power supply as soon as you can

I know how to get it working, but is it safe?

Thanks for your time, you're absolutely right about the new one. I don't haz money tho frown.gif, where I live even a mediocre power supply (ODIN 720W) is about $160. I'd have to wait until feb to get one from the internet.

It'd be safe as far as I know, I've just always understood that video cards work better with pci-e connectors when they're available

That will work but please read thru to understand the basics before doing that or it will give more issues rather than a solution;
