Modified 75W single-slot RTX 3060 runs on PCIe power alone but halves performance and overheats
↗
A shunt-modded RTX 3060 draws all 75 W from the PCIe slot, trading half its stock performance for compact size and frightening thermals.
Engineers building small-form-factor or embedded systems must weigh the trade-off between power budget and thermal headroom. This card demonstrates that even a well-understood GPU architecture can become thermally constrained when forced into a single-slot, blower-style design without external power.

The 75 W RTX 3060 delivers less than half the benchmark score of a stock 170 W model.
Thermal throttling pushes the GPU hotspot past 90 °C under load, despite the reduced power draw.
No external power connectors or backplate limit the card to single-slot, low-profile use cases.
