Why does my Huntkey T620 Snow keep rebooting in FF XV?
Whenever I unleashed massive magic attacks, the whole system would just black out and reboot without any warning, which is a total nightmare for any serious build. I dug into the logs and found that the 12V rail on the Huntkey Blizzard T620 Snow was swinging wildly between 11.4V and 12.6V when transient power spikes hit 650W, triggering the Over Current Protection (OCP). At first, I tried swapping out the power cables, but the system still crashed within ten minutes—a complete waste of time. I eventually dove into the BIOS and switched the CPU load-line calibration from Auto to L2 mode, while also replacing the single daisy-chained GPU cable with two independent PCIe cables. Monitoring with a multimeter showed the voltage drop tightened from 0.8V down to a manageable 0.2V. I actually overshot the first adjustment, causing temps to spike to 88℃, so I had to dial the offset back to +0.02V to find the sweet spot. Now the PSU fan chills at 1100-1200RPM and it's whisper quiet. After a four-hour stress test with zero reboots, the power delivery is finally sorted.
