I have been using my MSI Ventus RTX 5090 since April 2025, bought new from Best Buy. Well yesterday, while Playing Tekken 8 in 4K, my PC suddenly rebooted on it's own. After that, it continuously rebooted whenever I launched any game.
Turns out the 16pin adapter, and the 16pin port on the GPU burnt up. To be clear, I had no GPU overclock, no mods, no custom firmware. I was already aware of this being an issue for others, so I was extremely careful when plugging in the adapter initially. In a large case, so the adapter wasn't being bent from the glass. All four PCle power cables going into the adapter were individual, and into an EVGA SuperNOVA G2 Gold 1300W PSU.
In the process of RMA with MSI, what a great design connector. I know nothing really compares to the power of the RTX 5090, so suckers like me don't have other options. But if you're thinking of buying a RTX 5070 Ti or weaker, do yourself a favor and just get an AMD equivalent that doesn't use this poorly engineered 16pin connecter.
