Yes, PSU emits a loud pop upon receiving power.
I recently assembled a new PC using an Asus ROG Z790H, Corsiar 4000X case, and a Corsair 1200 PSU. After installation, I encountered several problems. The system makes a loud noise whenever power is supplied, even with the breaker on the back of the PSU remaining in the "permanently on" position. I'm currently using a wireless power switch. The existing PSU from my previous build never had this issue. Additionally, the Z790H features two 4+4 CPU sockets; should I connect only one? When powering up, the PC displays an error for the USB device linked to the ICUE lighting node, but it resolves when the device is removed and reinstalled.

Hi everyone, I gave my 6-year-old computer to a partner who now connects it to a smart switch that controls the mains power when not in use. However, after disconnecting the PC from the mains and then restoring power, it produces a loud bang. This occurs only under certain conditions... forums. First, try to figure out whether the sound comes from the PSU or elsewhere, and do so carefully.
Likely there is a surge of initial current. Should the wireless power control be turned off once the computer is powered down?
A frequent reason for a popping noise comes from capacitors bursting in the power supply unit, though this often includes a smell.
