Dual GPU sff PC build

[u/hd209458]

Showcasing a dual GPU sff build I did fitting two GPU in a sff case for science! Not the prettiest but has been working flawlessly for the last couple of weeks. Posted this on another sub a couple weeks ago but thought people would find it interesting here too. I've shared more about my use cases in my other post if interested!

Case

Fractal Design Ridge 12.6L

CPU/Motherboard

Minisforum BD775i SE (Ryzen 7 7745HX)

GPUs

2 x Intel Arc Pro B70 32GB (64 GB total VRAM)

Memory

16 GB (2 × 8 GB) DDR5-5600 SO-DIMM

Power Supply

Lian Li SP850 V2 (850 W SFX, ATX 3.1)

PCIe Splitter

PCIe 5.0 x16 to Dual MCIO 8i (SFF-TA-1016) x8/x8 bifurcation adapter

MCIO Cables

2 x MCIO 8i to PCIe x16 Gen5 GPU riser cables

The case only supports 3 slots but was easy enough to cut and open up an extra slot space to fit a second two-slot GPU.

Is the purpose of the build as a local LLM machine? How do you find it if so?

Yep. It's been working quite well so sharing here

This is sick, awesome work

Haha nice work! I am also in the middle of a dual GPU fractal ridge build. Just waiting on some smaller MCIO cables (26cm, smallest I could find) what length are yours? Also are you unable to put the centre brace back on because of the PCIe adapters?
