ElphaPex FP-102 PSU | 4400W Replacement Power Supply for ElphaPex DG1+ Crypto Miner
The ElphaPex FP-102 is the 4400W switching power supply for the ElphaPex DG1+ Litecoin / Dogecoin miner. Direct replacement when the original FP-102 fails — restores the DG1+ to full hashrate without any board-level repair. Pull the dead unit out of the bay, drop the FP-102 in, reconnect the AC inputs and the DC harness, and the miner returns to production.
Built with dual 220–240VAC inputs at 16A each for redundancy and to keep the per-leg current within standard PDU and breaker ratings. The primary rail delivers 17V – 20V / 200A (the higher voltage envelope compared to the FP-101's 12V–15V rail — pick the right model to match your DG1 generation), plus a 12V / 15A auxiliary rail for the control board. Compact 250 × 254 × 63.3mm form factor matches the original DG1+ PSU bay. PCB revision BC.
When to Replace the FP-102 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 the rated 17V 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 — replace immediately.
- Routine fleet refurbishment — proactive PSU swap on DG1+ units approaching 18–24 months of continuous duty.

FAQ — ElphaPex FP-102 PSU
Q: How is the FP-102 different from the FP-101?
A: The FP-101 ships with a 12V–15V primary rail at 265A (4000W total), while the FP-102 ships with a 17V–20V primary rail at 200A (4400W total). Different DG1 generations use different rail voltages — check your miner spec or email contact@lys-sz.com with your serial if unsure.
Q: Why does the FP-102 use dual AC inputs?
A: Two independent 220–240VAC × 16A inputs share the 4400W load — keeps the input current per leg low enough for standard PDU and breaker ratings, and gives the DG1+ redundancy if one circuit drops.
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: 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.
