If the high side is shorting out but you still have 12v on the low, I would suspect a shorted PWM IC, since that is really the only thing that would be linking the high side to low side and would explain the blown rectifier. I often find that isolating the fault on a PSU can be one hell of a rabbit hole. A lot of replacing components, test, something else blows, etc. My advice would be to buy a replacement unless this is purely for practice or learning.

Update I have assembled the psu tested it , it plugs in as normal without tripping the breaker , but there is no 12 volt, the big cap has 320 volt after pluged in . i have found a small diode that reads wrong i will change that and we will see.

Hi, I know this thread is old, but I´ve a PSU modelo "1815" from XBOX ONE X where the U2 IC blown and I can´t get the code of it, I can read it only ends with "0022T", if anyone have one at hand to get me the code would be awesome. Thanks in advance!
