Incoming AC passes through a fuse and an EMI filter to remove noise. A bridge rectifier then converts it to high-voltage DC (around 145V–160V depending on load and region).

Measure the voltage on the purple and green wires. You should see roughly 12V (standby) on the purple wire and a low logic voltage (approx. 4.4V) on the green wire. ps42419ha schematic work

Professional technicians often use a DIY Test Box with a series lamp (60W/200W) to prevent catastrophic shorts during testing. Incoming AC passes through a fuse and an

Short the green wire (PS_ON) to any black wire (Ground). ps42419ha schematic work
