How can I connect my second gpu that needs a 6 pin pcie when I doesnt have another one?

ryanabdulah · Aug 10, 2018

My power supply is Antec High Current Gamer HCG-620M, 80 PLUS BRONZE, 620 Watt Modular Power Supply.
I used it to connect my first gpu but now I need another 6 pin to connect to my gpu but I dont have one. I have free 10 pin ports on the power supply itself labeled PCIE/HDD. Which cable can I buy to make it work and how?

Hi Ryan,

You can start by telling us what GPUs you are trying to connect and what CPU you have so we can tell you if you've got enough power to run it all.

I know you said you dont want to SLI, but you wont be able to anyway as the 1060 does not support SLI.
How many monitors do you want to connect?

You need a new Psu with 4 x pci express cables.

Still don't see why you need a 1060 ?

Your 1070 has 2 x displayport & 2 x hdmi 2b ports.

You seem to have the budget for a PSU that has more power and enough cables.
