8 Pin CPU to GPU

sonnytbh · 8 Apr 2021 at 11:57

Hi all,

I've read some conflicting information about using the CPU4+4 output on my PSU for GPU connection.

Does anyone know if its possible to use a PCI-E 8 Pin cable to connect a GPU on the 8 pin port marked "CPU" on the PSU? I have used all of the GPU ports and would like to connect another GPU in the future.

PSU:
SuperFlower 850W Leadex Titanium PSU

Thanks!

No, even if the pinout was the same, the gpu cables at the PSU end won't fit into the cpu slot, the pins are shaped differently from what I can see, which is probably because the pinout isn't the same, and I wouldn't want to try to get an adaptor either, it's just not worth the risk.

Is the CPU slot even empty on the PSU? I would have thought the 8 pin CPU connector is required to be connected to the motherboard anyway?

Thanks for your reply, the PSU has 2 x CPU outputs, 1 is in use obviously and the other is spare.

Thanks, I opted to buy a new PSU in the end with some extra GPU ports. I'd rather not risk it with components being so expensive. Shame to have to go from Titanium PSu to Gold though but needs must.

This will result in genuine hardware death afaik.

Much easier to take a SATA/Molex connector and use a converter.

I've seen so many people say that SATA to PCie is a big no, no. I'm definitely avoiding it.
