The 12VHPWR connector on the NVIDIA GeForce RTX 40 series cards has been prone to melting ever since its launch but MSI has a simplistic fix.
MSI Helps NVIDIA GeForce RTX 40 Owners From Melting Their GPUs With New 12VHPWR Cables
According to NVIDIA, the main issue that led to so many NVIDIA GeForce RTX 40 series graphics cards melting was due to user error. It was found out that when the cable wasn't plugged into the connector slot entirely, it led to power disparities which meant higher temperatures and caused major meltdowns around the cable pins. This affected both the cable itself and the graphics card.
To rectify this issue, some cable and PSU makers offered angled connectors which made sure that there wasn't lots of force on the cable when plugging it in from an angle as that could cause slight imbalance in the way the connector was plugged in. But MSI has a more clever solution which is in the form of its new 12VHPWR cables bundled with its PSUs.
The new PCIe Gen5 12VHPWR connector cable from MSI is the same one shipped with its ATX 3.0 PSU lineup. There's virtually no difference in specs but what has changed is the color of connectors on both ends. The connectors on the cable are colored yellow and what MSI is doing is basically using a color identifier to let users know if the connector is properly inserted from both sides. If there's a visible gap when the connector is connected to the PSU or GPU, that means an improper connection and chances of the GPU melting or causing trouble in the future.
To make sure that the 12VHPWR connector is inserted properly, the yellow parts need to disappear entirely. Plugging in the 12VPWR connector this way will also let users know just how much force is actually required to get this bad boy into the connector slot properly.
MSI really thought out of the box here and this will definitely save a lot more users from burning up their brand-new cards. The company will be shipping these cables with their ATX 3.0 PSU. Meanwhile, ASUS is offering a new feature in its GPU Tweak III utility that will also let users know if the 12VHPWR connector is plugged in properly or not.
