My system keeps rebooting during time loop transitions in Deathloop with a Huntkey Blizzard T620 Snow. How do I fix this lag?

The moment the screen went black and the PC rebooted, I knew my PSU's transient response was failing. Looking at the logs, during the transition effects of the time loop, the total system power draw spiked from 320W to 580W in about 0.1 seconds, causing the 12V rail on the Huntkey Blizzard T620 Snow to dip to 11.4-11.6V. I tried swapping in high-end modular cables first, but the crashes kept happening randomly, which was incredibly frustrating. I then went into the motherboard power settings, changed the Load-Line Calibration (LLC) from Auto to Medium, and disabled deep CPU sleep states. Monitoring with a professional multimeter, the voltage ripple shrank from 0.6V to under 0.1V, and the system survived three consecutive loop transitions without a hitch. When I first pushed LLC to the maximum setting, I noticed a high-frequency coil whine during idle, so I backed it off to Medium for a cleaner signal. The PSU fan stayed between 900-1100 RPM with a chassis temp of 35-40°C. After four hours of OCCT stress testing, I've confirmed zero reboots. Power delivery is finally sorted.
