I have an ASUS ROG Strix- G513IH-HN008, motherboard G513-6050A3249301- MB-A04 (A4)
When I received the device, the device has no function. After an investigation, I found that the PWM CONTROLLER RT6575B (U6100) is getting warm and there is a short circuit at the 3V3 output. This normally supplies 3V3 for the embedded controller IT5571E-128 (U301). When measuring and analyzing with a thermal imaging camera, I found that some components are damaged: SLG4E42553VTR (U8500), IT5571E-128 (U301), LAN RTL8111H (U450), LOGIC 74LVC1G08GW (U1900), RT6575B (U6100) All these components are on... -
I have seen some board on eBay and Aliexpress but I have not seen any for SMPS switching power board modules I would like to build one if I can not find one that is already made
Dose anymore known if there is such a module and where would I find some
While searching this topic on google I found this

I believe Chip 2 is BIN is the main one as it contained the Windows product key, marked with XXXXX for now.
SN: PF3G1REP
MODEL: 20KW-00J1AU
PROBLEM: Turns on blank screen, charging circuitry motherboard looks good. I have tried another firmware here - but resulted in 5V will not go to 20v due to different PD firmware I believe - using the current firmware it does go to 20V.
Requesting a firmware clean/BIOS region cleaned. Here is output from ME Analyzer:

Hi, since both the Dell Precision 3440 and the Precision 3450 have the same chipset W480.
I ask you if it is possible to add the correct microcodes for the Precision 3440.
I am adding the list of files that I have extracted from the Bios in order to help you understand if it is feasible.

This board had the initial fault in VRM with high side Mosfet from PWM1 (phase 1) getting very hot. It also had the VRM caps quicly heating up in 10-15 seconds after power on.
This board uses mext ICs and Mosfets in VRM:
- ADP3180 PWM controller - in 3 phase mode
- ADP3418 as Modfet drivers
- High side Mosfets STD38NH02L (from ST)
- Low side Mosfets STD90NH02L
Some of the symptoms were very similar with the "Dead Asus P5P800-VM" in this forum.
I had the sawtooth voltage on Vcore too this was probably the cause of the Vcore caps...
