Update on my MWE750 it broke again but I fixed it again (I hope)

it started turning off and immediately after turning on again, the capacitors might've been a red herring this whole time, i could get it to start by manually shorting the PS_ON# to ground multiple times until it would stay on then pressing the power button on my motherboard, this worked less and less as time went on, until it didn't, at which point I found 2 shorted 12v mosfets P16 N04S, the fix was replacing all four of them with BSC010N04LS from a dead HX1000 I have seems to have fixed it, and my no load power draw...

An actual fix story:

Hello everyone, I have a MWE 750 Gold mpy-7501-acaag that uses the exact same PCB as this 650w model, I was having issues where as soon as I press the power button it would turn off when the 24 pin was connected to certain motherboards, I narrowed it down to a problem with the 5v rail by depinning every rail from the 24 pin and adding one rail at a time until the problem came back. Initially I tried replacing the main cap but that did not help.

[B]what fixed it[/B] was replacing 2 input filter caps and adding 2 more input filter caps and 2 output...

I've gotten it to start with a dead bug 16pin bios chip, with VCORE and DDR4_DRAMRST#, VCCGT is missing but apparently that's normal?

Problem is it doesn't stay on it just starts then fans spin a little faster, then it goes off, nothing on screen.

The ec seems healthy, battery light and front leds work, and even detects no ram properly

Could this be signal integrity issue with my deadbug bios chip?

Re: Dell Precision 5530/XPS 9570 no reaction

Huge development for me, it seems the bios chip was broken, I temporarily replaced it with one that's half the size, just to see if it powers on, and it did, obviously it doesn't boot since it's missing half the firmware but at least that confirms what's broken

Every voltage is present until PCH_PLTRST#, but I'm able to run the D key display tester

Another thing I noticed before I replaced the bios chip was that the CLK pin would go high for about 2ms and just drop, I'm guessing it was waiting for the chip to...

I have the same board but mine has SIO_SLP_A# 3.3v and 1vsp disappears randomly

Did you ever fix the board?

Is it8655e programmable?

Hello, does anyone have schematics and boardview for MSI B450M Gaming Plus MS-7B87 Rev 1.1?
