The RTX 4090 makes use of 16-pin 12VHPWR connectors and natively helps ATX 3.0 energy provides. Customers who do not wish to spend further to improve from their ATX 2.0 PSUs can use the bundled adapters on their 8-pin connectors.
One of many new incidents occurred after round six months of use. The consumer claims to have set the connectors appropriately and securely. Equally, a second consumer claims his properly-connected adapter went up in smoke about six or seven months after set up. The consumer primarily used the PC to coach AI fashions somewhat than play video games. A peculiar facet of the second report is that the affected PC comprises a second RTX 4090 that hasn’t skilled any issues.
A 3rd report comes from somebody utilizing a third-party Corsair SF750 platinum adapter. Assuming it was appropriately related, this occasion may counsel that the adapter is not the issue. Even stranger is that the consumer restricted the GPU to 70 % energy and paired it with a modest Ryzen 7600 CPU, so the PSU actually wasn’t overtaxed.
