You mean PCI-e 2.0 x1 slots? If they are PCI-e too, then yes, but You would need riser cables to connect PCI-e x16 card to PCI-e x1 slot (Riser with x16 female and x1 male)

I would suggest using risers x16--> x16 too on those 3 x16 slots aswell.

Hi,

Yeah, meant PCIe 2.0 x 1 slots. Im going to buy some risers this weekend. Does the risers I need have to be powered riseres? For either the PCI-e x 16 or PCI-e x 1 slots? I plan on having 3 gpus connected via PCI-e x 16 and 1 connected via PCI-e x 1.

I saw people recommending powered ones, why? I don't know, if someone could explain it I would be gratefull

Yes, of course it is possible, I would even recommend that -> if one breaks You still have another working, and 2x 750 are way cheaper and easier to access than one 1500W. At least at my place.

Thank you for the reply. I am about to buy another power supply, but wanted to check that it would work first. How does it work, do you just switch on one PSU and then switch on the other PSU?

How about the motherboard. Can you have 3 cards connected via PCIe x 16 and 2 cards connected via PCI2.0 x1 slots?

Thanks.

Hi,

Im just wondering if its possible to have 2 Power Supplys connected to one rig?

For example, if I had 2 850w PSU's. Could I have one of them connected to 2 gpu's and the other connected to 2 GPU's plus the mobo and HDD? If so, how does this work and how would I go about it?

How to do that? Just plug 2 cards to first PSU, and rest to 2nd ^^

Also, I have just purchased an AS Rock 970 Extreme 4 Mobo, which has 3 PCIe x 16 slots and 2 x PCI Express 2.0 x1 slots. Is it possible to have 3 gpus connected to the PCIe x 16 slots and then another one or two connected via the PCIe 2.0 x1 slots? Or would this be to many gpu's for the motherboard?

Any advice would be very helpful.

Thanks.
