It seems unlikely the PSU is the issue unless it was nearly failing before. It's still a chance, though reduced. Did you remove the CPU during installation of the AIO? How is the AIO linked—directly to the Mobo's pump header or via a fan header? I'm trying to capture an image for reference to help narrow down the problem. The simplest option would be to revert to the previous cooler and check if that resolves the issue. If not, it probably isn't connected to the AIO or the mounting/disassembly steps.
It seems the pump might be drawing more current than the system can manage. According to the motherboard manual, the header supports only 12V/1A. If the AIO pulls extra load—especially at higher speeds—the board could trip due to overcurrent protection. Checking the AIO’s specifications for power consumption would help confirm.
You just tried a vintage CPU cooler, but it keeps restarting—could be related to the power supply unit.
