is not merely about drawing lines between symbols—it requires a holistic understanding of power electronics, noise mitigation, and thermal management. By following the pinout guidelines, calculating passive components accurately, and avoiding common routing pitfalls, you can harness this versatile IC to build robust DC-DC converters.

: The wiring uses a 6-pin and 4-pin configuration rather than the standard 24-pin ATX. Testing requires a custom DIY test box or a known-good HP motherboard.

High-value resistors that provide the initial "kickstart" power to the standby IC can fail open-circuit, preventing the power supply from starting even if the main fuse is intact. Primary Filter Capacitor:

: Look for the input fuse (FS801) and bridge rectifier (BD801S) to ensure primary AC is entering the circuit.

: Monitor the high-voltage main smoothing capacitor for signs of swelling or leakage. Repair and Testing Steps
