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.

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??
