Hi.
I have ASUS M5A78L-M USB3 rev 1.01.
The power supply didn't work. I have changed it to another one.
Main responds on the button. The power supply starts up.
P_VCORE_EN, comes to ASP1003QGK-C, but PU1 (PWM power supply to the processor) does not start.
HUB SU1 SB710 (A14) FCBGA528 AMD 218-0660017 receives only one 1.2V supply. Doesn't start and stays cold.
SPI, has all voltages risen but there is no exchange.
Power sequence stops at step 10.
At the same time, NU1 RS780L FCBGA528(HDMI) AMD 215-0674058-00 receives all power and heats up.
CLOCK CU1 ICS9LPRS483BGLFT is working.
I Suspect the ASP1003QGK-C
The problem is that I can't find either the Datasheet or newone part.
There are ASP0905 and ASP1102 on sale, but there is no datasheet to check compatibility.
Help is needed.
1. Is there a possibility of another problem whether I identified the problem correctly?
2. Need a datasheet for PWM ASP0905, ASP1102, ASP1003 to select correct replacement.
Thank you an advance.
