An 8-Pin Power Adapter Melted on a Radeon RX 7900 XTX, and Thermal Grizzly Is Investigating

A Radeon RX 7900 XTX owner found a badly burned Thermal Grizzly WireView power monitor after months of chasing freezes and black screens, VideoCardz and Tom's Hardware reported around September 17, 2026. The WireView routes power through three standard 8-pin PCIe connectors rather than Nvidia's failure-prone 12VHPWR plug, the newer high-wattage connector known for melting. The owner said the plugs were fully seated. Thermal Grizzly asked to inspect the unit, and a second user reported the same damage on the same reversed 3x 8-pin adapter.
