Is this accurate:
You are having random reboots that you believe are tied to the Corsair Link software and AX1200i reporting incorrect 12V rail amperage?
Not quite, but close. The reboots are not random, they only happen if I have multi-rail OCP enabled in Corsair Link, and only if a PCIe rail over-reads.
There are two separate, but related problems:
Problem 1: I am getting incorrectly reported 12v (PCIe) rails, which overread by a large amount. The same problem as in the linked videos. This problem has persisted across software reinstalls/upgrades, and has persisted with a new RMA PSU and link dongle.
As long as I don't try to enable multi-rail mode, this causes no other problems. I can use the PSU as a single-rail PSU and the system is stable. I cannot however enable multi-rail mode, because if I do (by checking the OCP tickboxes in the link software) then I get;
Problem 2: The next time the rail in question over-reads (eg. exceeds the set OCP trip point) the PC will reboot. (it's an instant reboot straight to a black screen then the BIOS, just as though the reset button on the case had been pressed).
JonnyGuru has replied in the thread on the Corsair forum, saying that OCP would not cause a reboot, only a hard shutdown that required power-cycling the PSU itself to reset. Now I agree that is what should happen, however I get reboots when this happens.
I don't get reboots any other time - it's definitely only happening when multi-rail OCP is enabled and when a rail over-reads. More details in the thread on your forum.
