Hi all, I am trying to do a monitor conversion and hoping to reuse the PSU. The model number is ``ADP-300AF T``. It has 3 connectors, other than the AC input.
* One big 12 pin molex connector connected to the logic board.
* One small 2 pin connector connected to the power button.
* One small 7 pin connector, connected to the logic board via a flat cable.

The big 12 pin molex connector is apparently the 12V rail. It's also confirmed by the schematic.
The 2 pin connector for power button is probably a passthrough to the logic button. The PSU usually needs a PS_ON pin to be pulled to the ground to keep on, if it's like an ATX PSU.
The 7 pin connector probably has that PS_ON pin, along with some other pins. I'm trying to figure out their functions. According to the schematic, they are:
# PWR_BTN_R
# GND
# SMC_ACDC_ID_R
# TSNS_ACDC_N
# TSNS_ACDC_P
# GND
# BURSTMODE_EN_R_L
-
So, it confirms my suspicion about the power button. Pin 1 must be the power button pass-through. I looked up [link|https://electronics.stackexchange.com/questions/285029/the-meaning-of-burst-mode|burst mode], which I probably don't need to worry about. But I'm unclear about the rest 3:
* SMC_ACDC_ID_R
* TSNS_ACDC (Positive and Negative)
-
Can someone shed some light on them?
P.S. does anyone know what kind of connector it is? I hate cutting the original cable. Worst case, I can solder wires to the PCB but it's kinda hard to do with the connector in place.
