My GPU has x2 6-pin PCI-E connectors, but I only have 1 6-pin PCI-E

Mobilizer · Dec 1, 2015

I am using an R9 380 4GB and a Seasonic G Series 550W PSU. It only comes with 1 PCI-E connection for the GPU.

I didn't plan to overclock because I'm using an i5-4460 on an H97 MOBO anyway. Will the single PCI-E connection work? Do I buy a x2 PCI-E cable at Microcenter?

Another option would be to use 2 seperate PCI-E cables to power the same GPU. Will that work too?

Connecting a single one will not work. You will definitely have issues. Having an additional connector will help however, so you can buy the required converter to make it work.

Hey thanks. Just updated my question asking if I can use two separate PCI-E cables and you just answered it. Thanks.

(bonus question: will there be a voltage difference if I stick with two separate cables? in other words, is there any cons to using 2 cables instead of one?)

There won't be any real difference, as long as the power supply is able to handle the load of the card. I don't see why yours shouldn't be able to.
