8-Pin PCIe Plug Melts on Radeon RX 7900 XTX
A Thermal Grizzly WireView adapter connected to a Radeon RX 7900 XTX graphics card has burned out, raising concerns about the reliability of 8-pin connectors, with the cause of the failure still unknown and under investigation
An 8-pin PCIe plug on a Thermal Grizzly WireView adapter connected to a Radeon RX 7900 XTX graphics card has burned out, suggesting that 8-pin connectors are not immune to failure. The affected connectors showed visible signs of burning and melted plastic.
The user experienced frequent freezes and black screens before discovering the damage. The connectors were fully inserted at the time of the failure, which rules out improper seating as a possible cause.
Thermal Grizzly has contacted the affected user to investigate the damaged WireView adapter. The company has previously pointed to poor electrical connections, increased contact resistance, or damaged connectors as possible causes of overheating damage.
In a separate incident, a modified RTX 5090 graphics card successfully ran on three 8-pin connectors, pulling up to 900W and reaching 3,400 MHz. This suggests that 8-pin connectors can handle high power loads, but the failure of the Thermal Grizzly WireView adapter raises questions about their reliability.
## Why it matters The failure of the 8-pin PCIe plug on the Thermal Grizzly WireView adapter is significant because it highlights the potential risks of using 8-pin connectors, even though they are considered to be more reliable than the newer 16-pin connectors. The incident is a reminder that even established technologies can be prone to failure, and that manufacturers and users must be vigilant in monitoring and maintaining their equipment.
The investigation into the cause of the failure is ongoing, and Thermal Grizzly is working with the affected user to determine the root cause of the problem. The outcome of this investigation will be important in determining the steps that need to be taken to prevent similar failures in the future.
