The long-anticipated launch of the MSI RTX 5090 brought with it high expectations, driven by NVIDIA’s latest GPU architecture and MSI’s reputation for pushing performance boundaries. Touted as a flagship card for elite gamers and creators, the RTX 5090 was designed to deliver next-level visual fidelity, ray tracing, and AI acceleration. However, the release has been marred by a critical hardware issue: melting 12VHPWR power connectors.
The Return of a Familiar Problem
The 12VHPWR connector first made headlines during the RTX 4090 era, facing controversy over poor cable management, misalignment, and overheating. Despite multiple engineering revisions and extensive testing, the same issue has now re-emerged with the RTX 5090. This time, the problem appears to have hit MSI’s custom models particularly hard, with users reporting melting connectors, burned cables, and in some cases, permanent GPU failure.
User Reports Spark Alarm
Reddit threads, YouTube reviews, and tech forums have exploded with reports from early adopters. Many users claim that even when following recommended bending guidelines and using official adapters, the 12VHPWR connector on their MSI RTX 5090s has failed catastrophically. Thermal images and teardown analyses point to excessive heat buildup around the connector, often caused by high power draw and insufficient airflow in compact cases.

MSI and NVIDIA’s Response
MSI has acknowledged the situation, urging customers to halt use of affected units and promising an internal investigation. NVIDIA, in collaboration with PCI-SIG, has also launched a renewed assessment of the connector’s safety and design, hinting at future revisions or alternative power delivery methods. So far, no recall has been officially announced, but industry insiders suggest behind-the-scenes talks are underway.
Impact on the GPU Market
The timing of this failure is particularly disruptive, coming as competition from AMD and Intel gains momentum. Enthusiasts who were eager to invest in the RTX 5090 are now reconsidering their purchases, while system integrators face growing pressure to guarantee safety and stability. Retailers, too, are grappling with increased returns and customer concerns.
Engineering Oversight or Design Flaw?
Experts are divided on the root cause. Some argue that MSI’s aggressive factory overclocking and custom PCB layouts may be contributing to higher-than-expected current spikes. Others point to the 12VHPWR connector itself, questioning whether it was ever suitable for such extreme workloads in consumer-grade hardware. The lack of a universal standard in cable quality and connector tolerances only adds to the complexity.
