Ps5 losing power in ps5 game

kyle19s · Dec 13, 2025

Hi ,
I have a ps5 that lose power when launching ps5 game.
I changed ssd controller and clean it and put a new liquid metal but still the same problem .
Uart tell me xdpe bus but after changing 3 xdpe the problem is still the same.

This is going to be due to a failure of one of the CPU_Core or GFX_Core MOSFETs. Usually, UART will point you in the right direction, if it's CPU or GFX_Core MOSFET, if not - it's usually one of the 6 on the CPU_Core, because when GFX_Core ones fail, you'll get 2-sec BLOD (system won't even start), since there are only 2 of them on that rail.
And it's not a full short failure, like you won't find any short to GND on them, but it just stops working, so it might be hard to pinpoint which one had failed, but there are methods of determining that.
If you can't find the exact one that had failed, just replace all of them and system should be working fine after that

Thank you,
I changed all the 6 mosfet of cpu core and still the same.
I will try change gfx mosfet and see
Thank you my friend.

I had a case with UART error 808B00FF where the XDPE chip was faulty. After replacing the XDPE chip the issue was solved.

Did you replaced it with new one or from donor board?

That might have been one from a donor board, stripped for parts.
