Wannien 101v0 Power Supply Schematic Repack «2025-2026»

If you have a non-standard revision (v0.1, v0.2), you may need to "repack" the schematic yourself. Here is the methodology used by professional repair shops:

Power MOSFET (Q1): An N-Channel MOSFET (e.g., N-channel 4N60, 2N60, or AO4430 in D-PAK). This switches the primary side of the transformer on and off at high frequency (approx. 65kHz).

Snubber Network: A combination of a diode (FR107), capacitor, and resistor across the primary winding to suppress voltage spikes caused by leakage inductance.

Let’s walk through a typical schematic found in a wannien 101v0 power supply schematic repack. We’ll assume the 12V/8A variant. wannien 101v0 power supply schematic repack
