What type of connection does this cable support?

This male-to-male cable connects a PSU 8-pin (EPS/ATX) connector to a GPU PCIe 6/8-pin port. It is designed specifically for powering GPUs, not CPUs.

How do I verify my PSU’s compatibility?

Confirm the connector shape matches and verify the PSU pinout (Pins 1-4 = 12 V, Pins 5-8 = Ground). When unsure, check your PSU’s documentation or contact the manufacturer.

Why doesn’t it power my GPU even though it fits?

Some PSUs have different pinouts, so a physical fit does not ensure electrical compatibility. Always verify the pinout before purchase.

What should I do if it doesn’t work?

1)Ensure using the correct ports (EPS/PCIe labeled).

Replacing messy pigtails

Works good. Was using pig tails for my 7800XT. 2 of these gave me the needed power

Works perfectly to replace Y split GPU cable.

I needed another cable for my GPU, as I heard there were problems with the split cable that came with my PSU. It works just well and it functions as intended. The cable is made out of good material and it looks and fits perfectly. I didn’t have to worry about spending a lot on it either, so it was a good price for what I got.

Doesn't fit Corsair Type 4 power supply

I have a Corsair RM850x (uses Type 4 cables) and this cable will not connect to it. I'm connecting to the 8-pin EPS/PCIe connector on the PSU and it feels like one or two pins just won't fit (they all fit part way, but won't fully connect). And yes, I'm connecting the "PSU" side of the cable to the power supply, not the PCIe end.I tried multiple EPS/PCIe connectors on the power supply and none will fit the cable. My original Corsair cables fit all of them fine.

The quality looks good.

The quality of it looks good and it's what I have been looking for, can't seem to find it any where. Only question is from the pictures on the site and what I have seems different. One of the holes for the PSU have double wires in it and one of the other has nothing in it. My other ones don't look like this. Anyone else have this issue?

Works as intended

It fits perfectly on my card. Is a high quality cable. It is kind of tight on the plug on my power supply. I got it to work though I haven't had any issues.
