Open‑Source Tool Forces PC Shutdown to Stop RTX 5090 Connector Overload

A community-made app uses per-pin sensors on select ASUS cards to cut power when sustained over‑current risks could melt the GPU power connector.

Overview

  • The app, published on GitHub and reported August 6, 2026, polls per-pin current sensors twice per second and defaults to shutting the PC down if any +12V pin draws more than 9.5 amps for 15 consecutive seconds.
  • It currently works only on ASUS ROG Astral and some Matrix RTX 5080/5090 models that expose individual per-pin I2C sensors and requires Windows 10 or 11 plus Python 3.10 or higher.
  • The program is lightweight, uses about 35 MB of RAM, supports HWiNFO as a fallback, logs events to Windows Event Viewer, and lets users change the amperage and time thresholds.
  • Coverage notes conflicting attributions for the tool’s author — some reports name Humza Khalid and an AI assistant while others credit Redditor CoolerThanNos — and say the code was checked against independent implementations before use.
  • The utility is a software-level mitigation, not a fix: it can cut power to prevent melting but does not replace correct connector seating, hardware redesign, or manufacturer repairs and may cause data loss when it forces a shutdown.
