GUNNIR Professional GPU Teardown: Eight MPS DrMOS Power Stages Exposed
2026-08-08 · Compiled by Best IT Parts from public industry reporting
AI inference, 3D rendering, and professional content-creation workloads cause rapid current swings in GPUs, placing extreme stress on the core power delivery. This teardown of a GUNNIR professional graphics card examines the VRM architecture built to sustain low-voltage, high-current output under transient loads. The analysis reveals eight MPS DrMOS power stages handling the GPU core supply, along with the supporting PWM controller, bulk capacitors, and PCB layout choices that keep ripple and heat in check. The article details how the multi-phase design shares current across stages, maintains voltage stability during sudden load spikes, and supports sustained performance for AI and rendering workloads. A valuable reference for IT parts wholesalers and component distributors tracking high-end VRM designs and power-stage component selection in modern GPUs.
