My Huntkey Blizzard T600 Snow keeps triggering a reboot during Apex ultimates; how do I fix it?

Every time I unleashed a full barrage in the final ring, my PC would just black out and reboot without warning. It was so frustrating I almost threw my mouse across the room. Even though the rated wattage of the Huntkey Blizzard T600 Snow is sufficient, the 12V rail was dipping to 11.4-11.6V during GPU transient spikes. I first tried disabling all power-saving options in the BIOS, but that just made the power swings worse, increasing the crash rate from once every two hours to once per hour—a total nightmare. I then inspected the cables and found high contact resistance at the bends of the stock wires, so I swapped them for a set of high-spec 16-pin modular cables. With a power meter monitoring the line, voltage ripple was finally contained within +/- 0.1V. I did panic for a second when I noticed the PSU fan doesn't spin until 40℃, but after forcing a full-speed test, I confirmed the cooling module is fine. Internal PSU temps now sit at 42-48℃ with about 88% efficiency. After a deep dive into the Windows power plans, the input response finally feels tight and responsive.
