12V on that wire on that specific PS is because manufacturer's like HP, Dell, Lenovo, Fujitsu like to use proprietary motherboards, connetors and power supplies specific for they need's. You should always check before use !
If the main capacitor voltage diminishes and nothing happens on discharging as soon as we switch off the ac supply, does this mean the capacitor is faulty?
You should have also tested the main capacitor on diode mode with a simple multimeter. The main capacitor voltage should also have been tested onboard with ac supply on. Plz share these readings if you have any?
Everything is fine and dandy, but you need safety disclaimer in these type of videos. What you did touching leads of that mains rectifier capacitor with bare hands is ☠ sentence for young players watching your video.
Thanks a lot i really enjoyed with this one
You are welcome brother
Now I am keenly expecting from you a video on hp ps-4321-9ha model also in coming days?
I am repair it often it is pfc based technology

Yes if no dropper resistors are installed.
