- 1 x 8-pin EPS
- 2 x SATA
- 2 x Molex (4-pin)
- 1 x PCIe 6-pin
Focus:
Most repairs involve replacing dried-out electrolytic capacitors or blown Schottky diodes. 2. Complete Unit Replacement hys3c210-cs power supply
- Confirm mains fuse and visual condition; replace with identical rating if blown before testing.
- Power initially through an isolation transformer and an inline residual‑current device; use a current limiter (variac or series incandescent lamp) to prevent catastrophic failure.
- With dummy load(s) present on expected output(s) — resistive or electronic load sized to ~10–30% of rated power — bring input up.
- Monitor input current, output voltage(s), output ripple (scope), and temperature rise over 10–20 minutes.
- If outputs are correct and stable, increase load stepwise to full rated (if known) while watching regulation and thermal behavior.
- Test protections: short outputs briefly (observing precautions) to verify overcurrent/trip behavior.
