There are two of this card. One works well, and I measure it to fix the faulty one, and the other. The problem is as follows; The card turns off when the current reaches 1.2 A, installing and starting the processor on the card. I get all the voltages without a processor installed. VCore 1.05, GCore 1.1 and other voltages of 5 V, 1.8 V and 3.3 V are available. There is no faulty mosfet, no heated voltage regulator. I removed all the tantalum and aluminum capacitors from the work card and attached it to the faulty card. Nothing has changed. When I insert the CPU, the PGOOD ISL95870 output drops to 0, then the VON ISL95835 signal drops to 0 and interrupts the strobe signals 95835 and 95870. The processor is not faulty because it is running on a different board. Also, I programmed BIOS many times with the same firmware model. I even copied it from work cards. The NTC and GNTC (gcore) resistors of the solid card and the faulty card are the same. There is no short circuit on the board smd capacitor, I checked them all. When the board rises above 1.2 A, it fails for 1-2 seconds and turns off the VCORE voltage. GCore remains available. Durable card pulls up to 3A at 12v. However, this card for some reason shuts off energy when it rises above 1.2A. I don’t know what to do. Since I don’t have an oscilloscope in which it is stored, I cannot observe the change until the energy is turned off. As a last resort, I will try to transfer all smd Vcore capacitors from a solid board to a failed board, although there is no short circuit capacitor. But before I try, I still want to know your opinion. Perhaps there is a simple malfunction, but I could not do this and tried to fix this card for several days. By the way, this card is an OPS (Open Pluggable Standard) card, it is not mainly different from a laptop, and it is an Intel i3 system based on HM65.
