PSU used in my AMD 7600X as well as 7950X PC is:
"Mining Zumax ZU 1850W ATX nonModular"

Cables and power supply connectors:

  • 8 cables with 6 + 2pin connectors (on each braid of 2 connectors, all-16 PCs)
    (4 long, 4 short)
  • 3 cables with SATA connectors, Molex
  • 1 cables for connecting to the motherboard.
  • 1 cables for connecting the processor.

I did simply cut a hole into both PC cases where the PSU cables leave PSU inside PC.
4 long and 1 short 8pin cables leave the PCs this way, allowing to power 5 GPUs outside for now.
One GPU is plugged into 7600X PC x16 PCIE slot and powered with one of the remaining 3 short 8pin cables.

I added two Instinct MI50s from basement, and unplugged my (only) 32GB Instinct MI50 GPU from x16 PCIE slot inside PC and connected outside as well.
This is system working.

All 4 long and 4 short GPU power cables of Zumax 1850W PSU are now in use.
4 long, 1 short and 2 cables with 2× SATA and 2× Molex each leave PC through side hole in PC case.
SATA splitter cable leaves PC back together with remaining 3× GPU power cables.

The 4 Molex connectors are used to power the 8 BBQ fans.
The Riser modules are powered with 8 SATA connectors.
I had to replace the 4× Riser card with a 6× Riser card, one x1 adapter plugs into x16 slot now:

After some recabling, now the visible GPU UUID order corresponds to OS view:

The 32GB Instinct MI50 keeps outside being slower than the other MI50s.
