Ps42419ha Schematic Work 2021 [PROVEN | 2024]
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窶�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
Before disassembling, you can verify if the schematic's main rails are functioning using a basic multimeter: Incoming AC passes through a fuse and an
Because this PSU contains high-voltage capacitors that can hold a charge after being unplugged, follow these safety steps: follow these safety steps:
