This is a headless GPU from Nvidia the CMP-70HX. Originally designed when crypto mining was still hugely done on GPU, since outclassed by modern Tesla setups offered by Nvidia such as A10, P10, Blackwell, etc.
Requires up to 250W this thing is hungry, 2x 8pin PCI connectors. Triple fan design, this also takes 3 slots in the case. Again, there are no display outputs here; Speeds comparable to a laptop Nvidia 3070Ti GPU. There are patched drivers allowing you to render using the GPU, and output display to another output such as onboard video or another, separate card. Guys name is Dartraiden on github, making patched drivers
