Had my workstation opened up to diagnose some bad RAM (eventually realized this is what was making the OpenCore installation unstable), and figured I'd shorten up the HDPlex cables a bit.
I didn't have any male ATX pins, so I could only modify the inlet section (fine, as it was the longer of the two). Made a totally new EPS connector—and I'm glad I did, because the double crimps on the DC-ATX 4-pin end were pretty bad (the pins didn't cover or grip the insulation at all).
Ended up putting in a new SSD (WD SN750), and installing macOS Big Sur. Humming along just fine, but waiting on Corsair to respond to an RMA for the bad DIMM.
