8-Pin Connectors Are Not Safe Either, as a Thermal Grizzly WireView Melts on an RX 7900 XTX
When we talk about burned power connectors on graphics cards, attention usually focuses on Nvidia‘s controversial 12VHPWR standard. However, a new incident involving a Thermal Grizzly WireView has shown that traditional 8-pin connectors are not completely safe from this problem either.
A Reddit user reported that his Thermal Grizzly WireView adapter melted after months of causing system freezes and black screens. What makes this case interesting is that it does not involve the 16-pin cable, but instead the version that uses three traditional 8-pin PCIe connectors, installed on an AMD Radeon RX 7900 XTX.
RX 7900 XTX Power Connector Melts Despite GPU Running Below 300W
Although the user says that the graphics card was running with a reduced voltage profile (undervolt) that kept power use below 300W, the connectors burned at the point where they plug directly into the card. This is not an isolated case with this setup. Another user reported the same problem with the same version of the adapter, although their GPU survived the incident and they later requested a refund.
Thermal Grizzly quickly got in touch to examine the damaged graphics card. The company explained that this type of failure usually happens when the connectors are not fully inserted. This can be caused by physical interference with the card’s backplate or by imperfect alignment or soldering of the adapter’s pins. A similar case happened in 2024, when a custom liquid-cooling block prevented the WireView from being seated correctly.
The case confirms that although 8-pin connectors offer a greater margin of tolerance than newer high-density interfaces, no connector is safe from melting if there is high electrical resistance. Whether caused by poor pin alignment, a lack of firm contact, or tight mechanical tolerance, heat building up at high-current points remains a real risk.
