Firstly thanks to anyone who can help with this. The main issue is if the PSU is compatible due to it using Corsair's type 3 connector.
This is the warning from pc build checks: ASUS ROG Astral GeForce RTX 5080 OC Edition requires a 16-pin 12VHPWR power connector adapter to connect three PCIe 6+2 pin power connectors from the power supply. Avoid using the same split PCIe cable, prefer separate cables.
