What happens if only 1 of the 2 8-pin pci-e connectors are used on a gpu?

[turkishjedi21]

I have a gtx 1070, and I only habe 1 pci-e 8 pin connector. This problem will be solved tomorrow when I receive a dual mole to 8 pin pci-e connector. Anyway, I was just wondering what would happen if I only used 1 of the 2 pci-e 8 pin connectors on my evga gtx 1070 ftw

make and model of power supply?

if your power supply does not have the proper pcie cables, you need a new power supply that does.

would be a shame to blow up you nice new card


the only adapter type you should use is a dual 6-pin to single 8-pin adapter

You need to use both 8 pin connections. You also should not use a molex to 8 pin adapter.

If your PSU does not have the necessary connections its a great sign it is not suited to run the card. Do not attempt to run it.

Whereas the one 8 pin (150) and PCI slot (75) can pull 225 watts which is theoretically sufficient for a 1070, I'd wouldn't do it. I also wouldn't use adapters.... while theoretically feasible, had enough boxes appear on my workbench when users bought low quality adapters, or overloaded a PSU rail. A PSU designed to provide the appropriate amperages over each rail is the only solution I can recommend.

that's my power supply. I know it barely has eno ugh wattage for the gpu along with every other component in my system (is 4590, 8gb ram, 2 har drives), but I really don't have the money to upgrade it at the moment

Listen to JackNaylorPE on this one. The PCIE connectors are designed to do one specific job that a molex cannot do. I know you don't have the money right now but think about having to buy a PSU and another 1070 when the molex adapter damages your card by sending non-uniform power to the GPU during gaming. It might not fail right away, but the cost of a new card is greater than that of a new power supply.

Alright. I'm not very patient in terms of getting new things, but if it means saving 500 dollars, I'll do it. Thanks guys
