My Huntkey Blizzard T600 seems to have voltage drops during flashy skills in Kai no Kiseki, causing stutters. How do I fix this lag?

I hit a massive stutter during a combat sequence, and in a fast-paced command battle, that kind of hitch is absolutely lethal. Looking at my logs, the 12V rail on the GPU was dipping to 11.4V during peak loads, which triggered a hardware-level downclock. My first instinct was to lower the GPU power limit in software, but that just cost me 15 FPS—a terrible compromise. I ended up swapping to the original modular cables from the Huntkey Blizzard T600 and forced the power plan to 'High Performance' while killing all C-states in the BIOS. After that, the voltage stabilized between 12.0-12.2V, and the drops vanished. I did run into a snag where the new cable routing choked my airflow, and temps spiked until I reorganized the back panel. Now the CPU stays at 62-67℃ and the PSU module is around 45℃. AIDA64 stress tests show voltage ripple is under 1%, so the power delivery is finally rock steady.
