ElphaPex FP-104 800W PSU – DG Home 1 Miner Replacement

ElphaPex FP-104 Power Supply – 800W PSU Replacement for Elphapex DG Home 1 Miner with Quiet Cooling & 5-Fold Intelligent Protection

The FP-104 is a high-precision regulated power supply designed specifically for the Elphapex DG Home 1 miner. Rated at 800 W with headroom above the DG Home 1's ~630 W consumption, it is the original replacement power accessory for the DG Home 1 — application-tuned so the miner can sustain continuous full-load operation at 2.1 GH/s hash rate without the voltage instability, dropouts and restarts that a generic PSU inevitably introduces.

Four core advantages define the FP-104: quiet operation for home use, long-term operational stability, strong device compatibility, and durability. It resolves the recurring DG Home 1 faults — unstable power, voltage fluctuations, overload tripping, noise pollution, ageing-related failures — and balances low-noise domestic operation with the industrial-grade regulation the miner needs to stay at spec.

5 Key Features

1. Dedicated DG Home 1 compatibility — stable output under full load, eliminates power fluctuations, device disconnections and restarts caused by insufficient supply.
2. Wide voltage adaptability (AC 100–240 V) — handles unstable household mains, voltage deviations and peak-hour voltage drops without passing them through to the miner.
3. Five-fold intelligent protection — overvoltage (OVP), overcurrent (OCP), overload, short-circuit (SCP) and overheat (OTP) with automatic intelligent power-off on any abnormal condition.
4. Quiet cooling with automatic fan-speed control — low-noise operation at low load, no high-frequency whine at full load. Purpose-engineered for home / residential deployment where fan noise matters.
5. Fire-resistant metal casing + high-purity copper circuit core — excellent heat dissipation, lower failure rates, extended operational lifespan.

When to Replace the FP-104 PSU on a DG Home 1

• No output on power-on — the miner refuses to start and the wall breaker trips repeatedly at power-on.
• PSU fan not running but audible noise — high-frequency screech or hiss coming from the PSU with the fan off.
• Frequent miner restarts — DG Home 1 reboots unexpectedly and hash rate drops without a clear network or firmware cause.
• Ageing PSU signs — overheating, unusual mechanical noise, burning smell.
• Preventive replacement — after prolonged high-temperature, high-load operation, a scheduled swap keeps the miner uninterrupted.

7×24 Continuous Full-Load Operation

The FP-104 is rated for continuous 7×24 full-load duty. The intelligent temperature-controlled cooling keeps the internal thermal profile stable across long unattended sessions, and the fire-resistant chassis reduces the fire-risk profile of a PSU running in a domestic environment. This is what distinguishes the FP-104 from a generic bench PSU rated for the same wattage on paper but not qualified for sustained mining duty.
