GinTai 8-Pin GPU Female to PCI-E 8-Pin Male Graphics Card Power Extension Cable (GPU to GPU) Adapter for NVIDIA Tesla K80 M60 M40 P100 030-0571-000 (4-inch; 10cm)

Works to connect two (2) PCIe 8-pin power cables to one (1) CPU 8-pin for the GPU. If you want to be extra safe, remember to use two separate PCIe 8-pin power cables, instead of one PCIe cable with two ends.

Took a little extra pressure to plug it in but I got a nice "click". This uses 2 of the same cards that you would plug into a normal video card like a 3090 etc.

We have to keep these cards around at work for regression testing, but any modern server that can accept a GPU is using the power connector for the P100, V100, A100, H100 style GPUs (which is what the "combined" end is). I was able to plug these into the motherboard and just use "half" of the connection to power these cards. Not the intended use but works great for our weird edge case.

Everything linked right up, power connectors were correct. So happy to have found the right power cable for this thing.

It works.

I only needed one but I bought two just to have an extra. One came with a bad crimp. Can't complain much for the price, so I didn't even bother to return it.

I'm sure the product works fine, but the exposed length of cable is just under 8.5cm, not the 10cm I expected which would have been just enough to hide the pcie cable plugs behind a gromet.Likely a return as this is almost double the price of the 8cm cable I originally got for my M40.
