ASRock's TempGuard Failed to Stop a PSU-Side Connector Meltdown on a $15,000 RTX PRO 6000 Rig

Posted on
An RTX PRO 6000 workstation reportedly suffered a melted PSU-side 12V-2x6 connector despite ASRock's TempGuard protection system.

Quick Report

A repair technician has reported a melted PSU-side 12V-2x6 connector on a system built around NVIDIA's $15,000 RTX PRO 6000 Blackwell Workstation Edition. The ASRock Taichi TC-1650T power supply used a native cable with an NTC temperature sensor and TempGuard protection, but the connector reportedly failed while both ends were fully seated.

The GPU reportedly survived and the damage was confined to the power-supply side. The technician claims the temperature sensor was placed on the ground side rather than the 12 V side it was intended to monitor, potentially explaining why the system did not shut down in time. The same GPU and PSU combination has reportedly seen a similar incident before, raising questions about sensor placement and connector reliability.
