My system keeps rebooting during heavy spell effects in Nightingale with a Huntkey Blizzard T600. Why is this happening?

Whenever I trigger massive AOE attacks, the screen just goes black and the whole rig restarts, which is a total nightmare for losing game progress. I dug into the logs and found that this T600 unit suffers from a 120-180mv voltage drop on the 12V rail during transient peaks, triggering the motherboard's OCP. I initially tried swapping to higher-gauge power cables, but that was a waste of time; the crashes still happened every 40 minutes. I eventually went into the BIOS, navigated to Advanced, then Power Management, and switched the mode from Auto to High Performance while disabling C-State deep sleep. Using an oscilloscope, I saw the erratic ripple curve flatten out to 30-50mv, and the system finally stayed up for 12 hours straight. Disabling power saving bumped my idle draw by 15W, but a quick tweak to the CPU offset voltage balanced it out. Now the PSU fan sits at 1100-1300 RPM with temps between 42-48℃. Everything is saved and stable now.
