Question Question about PSU cables

[EnchiladaBradda]

I recently purchased the tuf gaming 1000 watt 80 plus gold power supply along with my 7900 xtx. The 7900 XTX has ×2 8 pin connections that need to be powered. This power supply came with 1 8 pin pcie connector, and another that looks just like one, but one end has 7 pins instead of 8. As in, 1 of the cavities that normally has a pin, doesn't. Is this normal? Will this properly power my GPU?

From what I can see, your PSU should have shipped with 3 6+2 PCIe cables.

It seemingly didnt. It DOES also have a cable that is 12 pins for the side that plugs into the PSU and the other side is x2 6+2 cables. Is that one cable sufficient?

a 1000W PSU with just one 8 pin connector... Highly unlikely.

The cable datasheet shows that it does have 2x8 pin cables.

Yes.

To be clear, it came with other "8 pin connectors) but 2 of the 3 included only have 7 actual pins on the side that plugs into the PSU

 

[EnchiladaBradda]

Yes.

Oh. So that's good then? Just that one cable? Well cool. Thanks. Unsure why 2 of these 3 cables have only 7 pins on one side though

If you zoom in a bit into the cable specification PDF i attached, you can see the "PCIE CABLE 1 to 1 x2" That's the 2x6+2 cables. And yes its sufficient

 

[EnchiladaBradda]

not just one cable. i don't think it will be sufficient. 2 of them are included with the PSU. use both.

This is why I'm confused. It only needs 18 pins total in the power supply. This single cable has 18 pins on one end (comprised of x2 6+2) and 12 pins on the other end which plugs into the power supply. So why would I need a 2nd cable if I have all pins accounted for on the end that plugs into the GPU?

Sorry, 16 pins total for GPU not 18

Oh, my bad, yes that cable should work fine. I thought you were going to plug just one 8 pin cable.

Oh OK. Well sweet. Thanks
