Hello. I have an issue with my 7700XT (nitro+). I have it paired with an I5 12400F and 16GB DDR4 RAM. My PSU is 600W (I know that 700 is recommended). On AC Odyssey e.g. I get 65-80 fps 1080p ultra settings while benchmarks on Youtube show that they get 100-120 fps at these settings. I also noticed that my card only draws 90-110W. What do you think might be the problem? My PSU has 1 PCIe cable that splits into two PCIe connectors. Could that cause the problem? I also don't know if the card is undervolted. I am about to get a 750W PSU but first I'd like to hear your opinion on this matter as I am completety inexperienced in GPU power matters. Thank you
