A Redditor by the handle VersauteGurke recently posted their travails with the power cable of an MSI GeForce RTX 5090. The cable, with its bright yellow-tipped head, had melted due to the insane amount of power flowing through it.
VersauteGurke said that his PSU was a Corsair HX1500i, which is more than plenty for a GPU like the RTX 5090 and its 575W TGP.
“Over the past few days, I’ve been experiencing an issue where my monitor suddenly turns off and shows a “DisplayPort not connected” message. I’ve reinstalled the driver and tried everything to fix it, including working with NVIDIA support. However, I then discovered that the cables are melted. Could it be that only the cable is faulty while the graphics card is fine? I don’t see any melted or damaged pins. I’m using a Corsair HX1500i 1500-watt power supply.”

The irony of the situation is that the yellow-tipped 12VHPWR-2×6 power cable is supposed to be a safety feature for MSI components – it’s bright yellow by design as a way to inform gamers if the cable head is fully pushed all the way into the GPU power socket. If you see the yellow, the connection isn’t secure.
The good news for VersauteGurke is that their card didn’t appear to have sustained any damage. The RTX 5090’s PCIe port didn’t appear melted, nor did it have any burned pins. Basically, MSI’s cable literally took all the heat.
This marks the second case of 12VHPWR cables melting with RTX 5090 GPUs, the first report going all the way back to February of this year. Prior to this, the issue was prevalent with NVIDIA’s last generation flagship, the RTX 4090.
