I have the Sapphire 7900XTX Nitro + with a TDP around 400W, though LACT software detects it as up to 339W by default and can raise it to 350W. The readings from MangoHud seem off, showing about 300W while Windows previously reported 400W. There seems to be an issue with the system recognizing GPU power correctly. OS version is Fedora 40, CPU 7800X3D, GPU 7900XTX, RAM 32 GB DDR5, SSD 1TB WD Black SN850X. SOLVED: I had to turn on overclocking and set the power draw to 400W since it wasn't enabled by default. The problem with the default limit is unclear, but it now functions properly.

Only the overall GPU and die power are displayed, not the total board power.
