I have 2 PSU's 850W and 750W 1 motherboard and 4 cards 280x GPU's. I would like to connect 2 of the GPU's to a second PSU. So it means 2 cards are powered by PSU A. and 2 by PSU A via the motherboard and PSU B via the 8 and 6 pin connectors.

Will that be OK? Because I heard that you shouldn't connect a GPU to 2 seperate PSU's.

Do I have to buy powered raisers for the 2 GPU's?
