GoKawiilAMD Radeon RX 7900 XTX Owner Finds Melted 8-Pin Power Connector
A Reddit user reported months of black screens and system instability on their AMD Radeon RX 7900 XTX before discovering burn marks on the card's 8-pin power connector after disassembling their PC. Notably, the connector was routed through a Thermal Grizzly WireView power monitor meant to prevent such damage, and while the monitor took the brunt of the melting, it kept the GPU itself from being harmed.
GoKawiil's interpretation of the reporting above, not reported fact.
Melting power connectors have largely been framed as a problem unique to Nvidia's high-wattage RTX 4090 and 5090 cards and their 16-pin connectors, but this incident shows that even AMD's lower-power 8-pin setups can fail, and that protective monitoring hardware isn't foolproof. It suggests the underlying issue may be broader than connector design or wattage alone, potentially involving manufacturing tolerances or connection quality across the industry.
- An AMD RX 7900 XTX suffered a melted 8-pin power connector despite drawing only 400W, far less than Nvidia's flagship cards.
- A Thermal Grizzly WireView power monitor absorbed the damage, preventing harm to the GPU but showing that safety devices can still fail under fault conditions.
- The case challenges the assumption that melting connectors are strictly a high-wattage Nvidia 16-pin problem, hinting at wider connector reliability concerns.
