The ElphaPex FP103 PSU is a high-performance replacement power supply designed exclusively for the ElphaPex DG1+ miner (Scrypt algorithm for LTC/DOGE mining). It serves as the official service part when the original FP102 PSU fails beyond repair. The FP103 restores full functionality to DG1+ miners with OEM-equivalent power specifications and improved reliability over the discontinued FP102 model. Compatible DG1+ variants include the 13Gh, 13.5Gh, 13.6Gh, 14Gh, and 14.4Gh models. The original DG1+ miner has a rated power consumption of 3950W and a Scrypt hashrate of up to 14.4 GH/s.
The FP103 is the updated replacement for the discontinued FP102 PSU. The key differences are:
-
FP103 is the newer generation, shipping as the default replacement part for DG1+ repairs.
-
FP103 offers an updated design over FP102 for improved reliability and future-proofing.
-
The FP102 PSU (original OEM unit) operates at 3420W (12-15V output), while the FP103 delivers a higher 4400W total output with a wider voltage range (17-22V).
The key takeaway: The FP103 is the direct, upgraded replacement for the FP102.
The FP103 includes comprehensive protection systems for safe 24/7 mining operation:
-
Dual AC inputs with 16A max per input for stable high-power operation.
-
Compact design (250 × 254 × 63.3 mm) for easy integration into mining racks.
-
High efficiency power delivery that minimizes energy waste and reduces heat generation.
-
The PSU is designed to be repaired at the component level with proper tools (a suitable soldering station, hot air gun, multimeter, and electronic load are required for advanced repairs).
The dual AC inputs (each with a maximum 16A current draw) are designed for:
-
High-power distribution: The 4400W total output requires robust power delivery that may exceed the capacity of a single standard mining PDU outlet.
-
Load balancing: Spreading the power draw across two inputs allows for more stable operation in professional mining facilities.
-
Redundancy: In professional rack setups, the FP103 is connected to two separate PDU outlets or power phases. If one input experiences voltage sag under high facility load, the second input helps maintain a stable DC output, reducing the risk of miner resets and hashboard errors that appear on pool dashboards as stale or rejected shares.
When installing, ensure both AC inputs are connected to provide the full 4400W output capability. If only one input is used, the PSU may not deliver the necessary power, causing the miner to function at reduced capacity or fail to start.
Follow these safety steps:
-
Power down completely: Disconnect the miner from mains power before handling any internal components to prevent electric shock.
-
Discharge capacitors: Before handling any internal components, use a multimeter to ensure large capacitors are fully discharged (confirm voltage is below 5V).
-
Remove the old FP102: Open the miner chassis, disconnect all power cables from the hashboards and control board, and remove the faulty PSU from its mounting.
-
Install the FP103: Secure the new PSU in the chassis and reconnect all power cables (main output to hashboards, auxiliary output to control board).
-
Connect dual AC inputs: Plug both AC input cords into dedicated 200-240V circuits (each rated for at least 16A).
-
Reassemble and test: Close the chassis, reconnect mains power, and verify the miner boots normally with stable hashrate.
In most cases, no firmware update is required. The FP103 is a direct hardware replacement, and the miner’s existing firmware should recognize the new PSU without issues. However, if you experience any post-replacement issues (such as power-related errors or instability), a firmware update to the latest version may resolve compatibility problems. Always download firmware specific to the DG1+ model from the official manufacturer source, as DG1 firmware is not cross-compatible.
