Title: Running different PSU on single mobo
Post by: revvv on December 22, 2013, 10:45:58 AM
Hey guys,

I have some PSU to use and I would like to use them to power my GPUs on a single mobo. How do I make them work together?

Use the paperclip trick  http://www.youtube.com/watch?v=u0OKmIuNtmI (http://www.youtube.com/watch?v=u0OKmIuNtmI)

Connect them to the same power bar, turn them on at the same time.

+1 for the paperclip.

Green and Black. That's all you need to remember.

Thanks guys just a question lets say I have 6 GPU.
With one PSU I connected 3 GPU and Mobo etc, another PSU I power other 3 GPU. When I turn on the PSUs should I be careful to turn them on at the same time? If I delay for a second??

I'd either wire them together so they both turn on at the same time automatically, or turn on the GPU-only supply first (but with as short a delay between the two as possible). I've never had a bad boot on a jerryrigged system using these methods.

I am thinking this is motherboard dependent...i couldn't get this to work on mine.  I would suggest that if you want the least amount of headaches stick to one psu.
