Hey. I recently upgraded my PC by replacing my GTX 1080 with an MSI Suprim X 3080 (10G LHR). I also bought a better power supply (Corsair RM850X) and case (Lian Li Lancool II Mesh) to accommodate the card.
After installing the GPU, my in-game performance has been awful. It's a laggy and stuttering mess with as little as 50 FPS on low settings. This is playing the same games where my GTX 1080 managed a consistent 144 - 240 FPS on the same settings. According to task manager and GPU-Z, the 3080 is running at nearly 100% load even for games at 1080p low settings.
I fear this may be a power issue. The Suprim has a 3x8 pin connector, which I'm currently using two PCI-E 8 pin (6+2) cables for. They're the pig tail type so one of the split ends is hanging loose (like this: View: https://i.imgur.com/4xTSui4.jpeg
). The reason I suspect this is because I've tried changing it to three of the 6+2 cables (for even worse results) and because GPU-Z shows I hit a performance cap due to Vrel and (sometimes) Vop as soon as I launch a game, which indicates there might be a voltage issue even though I haven't overclocked anything and am running at stock BIOS / MSI Afterburner settings.
So far, I've tried uninstalling the drivers with DDU and reinstalling the most recent version, plugging the PC into different power outlets, using a different power cable, switching out the 850W PSU for my previous 650W, and going for a few different cable configurations. The rest of my build consists of an MSI B550 Tomahawk motherboard, Ryzen 9 5900X CPU and 32GB of 3200 Mhz RAM.
I've uploaded an example of my GPU-Z log here (https://filetransfer.io/data-package/2EECXOdD#link) in which I go from idle at desktop to in-game and back to desktop because I'm not too familiar with the voltages and power draw aspects of this.
I'm really not sure what to do next so all help is very welcome. Thanks.
