PC randomly refuses to power on at home, but works perfectly at multiple repair shops. What could cause this?

My PC has a very strange intermittent power issue and I'm completely stuck.

Specs:

i5-12400F

Gigabyte B760M H motherboard

RTX 3050 6GB

16GB DDR5

500W ANT esports PSU

The problem is that when I press the PC power button and absolutely nothing happens. No fans, no motherboard lights, nothing.

The weird part is that I've taken the PC/motherboard to a Gigabyte service center three separate times, and the motherboard works perfectly every time they test it.

I've also taken the entire assembled PC to three different third-party technicians, and it worked normally for them as well.

But when I bring it home, the problem comes back.

I've tested multiple power sockets and even tested it in a different house/floor, so I'm not convinced it's simply one bad socket.

The shocking stuff is that this is happening when I just got into an internship(WFH) so its frustrating for me. But still gotta work on my home laptop which is so shit, can't even run minecraft on 60fps
