PS4 Pro rebooting after init main menu

Hi !
I have problem with my PS4 Pro.
After loading the main menu (2-6 sec) the console reboots (black screen and loading the Sony logo)

But if you enable safe mode, the console can work continuously for an hour or more.

I replaced the hard drive and also checked the cooling system.

I have an idea that this may be a faulty power supply, since it may not hold the load.

Or there is a gap somewhere in the motherboard.

I would be very grateful if someone advises something!
