ElphaPex FP-101 PSU | 4000W Replacement Power Supply for ElphaPex DG1 Crypto Miner
The ElphaPex FP-101 is the original 4000W switching power supply for the ElphaPex DG1 Litecoin / Dogecoin miner. Direct replacement when the factory-fitted PSU fails — restores the DG1 to full hashrate without any board-level repair. Common failure modes that justify a swap include drying primary capacitors, MOSFET fatigue, fan bearing failure and cumulative thermal stress from continuous duty.
Built with dual 200–240VAC inputs at 10A each for redundancy and balanced loading, the FP-101 delivers a 12–15V / 265A primary rail plus a 12V / 15A auxiliary rail for the control board. Compact 250 × 254 × 63.3 mm form factor drops straight into the DG1 chassis bay. PCB revision BC-V1.0 matches the latest factory production batch.
When to Replace the FP-101 PSU
- DG1 won't power on after a surge, brownout or long downtime — primary stage failed.
- Undervoltage faults at the hashboards — PSU output drift below threshold, boards refuse to start.
- Audible buzzing, fan failure or PSU heat alarm — magnetics or cooling fan degraded, replace before secondary damage.
- Visible burn marks, swollen capacitors or coolant contamination on the PSU housing — replace immediately.
- Routine fleet refurbishment — proactive PSU swap on DG1 units approaching 18–24 months of continuous duty.

FAQ — ElphaPex FP-101 PSU
Q: Why does the FP-101 use dual AC inputs?
A: Two independent 200–240VAC × 10A inputs share the 4000W load — gives the DG1 redundancy if one circuit drops and keeps the input current per leg low enough for standard PDU and breaker ratings.
Q: What power cord do I need?
A: A C20 to dual C19 splitter cable lets you feed both PSU inputs from a single PDU outlet. The matching ElphaPex DG1 splitter cord is sold separately.
Q: Is the FP-101 compatible with DG1+ as well?
A: Confirm against the DG1+ spec before substituting — some DG1+ runs may use a different PSU model. Email contact@lys-sz.com with your miner serial if unsure.
Q: Bulk pricing for DG1 farms?
A: Yes — email contact@lys-sz.com with your typical PSU order size and we'll send case-quantity pricing.
