Start the PC immediately and see what happens.
My new PC with a Ryzen 7 7800x3d, RX7900xtx and 32gigs DDR5 T-create RAM, powered on with a 850W Power 11 unit. After running for a while, it shut off completely. It starts up directly to Windows using the old drives, but after the first restart it won’t turn on again—there’s a click when I press the power button. That’s about it.
it has happened several times, either the drive is damaged or in the case of an M.2 SSD, it’s probably just a bit overheating. A cheap headsink with a pad and elastic band usually works, often the solution is something like "M.2 SSD heatsink set." If that doesn’t help, fixing your window installation might resolve the issue.
When constructing a new PC or refreshing an older one after swapping the CPU/Motherboard or other significant parts, it’s advised to reinstall Windows. Relying on your previous setup can lead to complications and demands extra work to manage software and drivers correctly. Regarding the clicking noise, does it simply trigger without power or display at all? Or can you sometimes access Windows briefly? First, disconnect the machine from power and verify all connections from the PSU to other parts, ensuring they’re correctly placed. Then remove the CMOS battery for a BIOS reset, reinstall it and try again. If it occasionally boots into Windows briefly before shutting down, overheating a component might be the cause. A failing PSU can also produce clicking sounds when trying to power on.
Unless OP is using some sort of power adapter to split a power cable they shouldn't be or they have something plugged in wrong, I don't think this system would be triggering the overload on a multi-rail unit. I think it probably would have triggered the overload the first time they powered it on before they were able to get into Windows and run it for a few minutes.
This shouldn't be an issue. The PSU they're using has three distinct PCIe power connectors, and the GPU model should only require up to three of them. The main concern would be if the OP mixed up the split PCIe cable for both 8-pin and three 8-pin connections, which could cause a problem. They should have separate cables for each 8-pin connection on the GPU, not using the split cable for both. @Luna0510 Could you share a photo of the power cables attached to your GPU? That would help confirm the setup.
