Why does my system reboot during CS2 firefights with Huntkey PSU?

I was clutching a round on Mirage when my screen went black and the PC rebooted. It was a mental breakdown moment. The Huntkey Blizzard T620 Snow was suffering from voltage drops under high transient load, cutting power to the VRMs. I first tried swapping the 24-pin cable for a thicker one, thinking it was a connection issue. That didn't work; the loose fit actually caused more contact resistance and frustration. I realized the issue was internal. I used GamePP BIOS Load Line Voltage Wizard to adjust the CPU load line from L1 to L3 and added a +0.02V offset.
