APW8 16-20V Power Supply Unit PSU for Antminer S15 T15 (Second hand device)

APW8 16-20V Power Supply Unit | Bitmain PSU for Antminer S15 and T15 (Second-Hand)

The Bitmain APW8 16-20V power supply is the OEM-spec PSU for the Antminer S15 and T15 miners. This listing is a second-hand, tested unit — the right repair path when an S15 / T15 PSU has failed in the field and a replacement is needed without waiting for new-stock turnaround.

Critical model-matching note: Bitmain shipped the APW8 chassis in three different output-voltage variants for different miners — 8V-9.2V (Antminer DR5), 10V-11V (Antminer S11 / D5), and 16.32V-20.04V (Antminer S15 / T15). They look identical externally but are NOT interchangeable. Always verify the voltage label on the PSU before purchase: the variant on this listing is the 16.32-20.04V version for S15 / T15 only.

The main rail delivers 16.32V to 20.04V DC at 95A, producing 1550W at the low end and 1850W at the high end of the voltage range, with ripple and noise under 1%. Setup time is under 2 seconds on cold start, and the built-in power-off protection trips in more than 10ms — standard safety envelope for ASIC PSU service.

When You Need an APW8 16-20V PSU

• Antminer S15 / T15 won't start — original PSU dead, no startup tick from the transformer.
• Repeated overcurrent / overvoltage shutdowns in the miner controller logs.
• S15 / T15 returning to production duty after long storage — old PSU capacitors degraded.
• Visible damage on the original PSU — burn marks, swollen capacitors, cracked PCB.
• Repair-shop bench stock for refurbishing S15 / T15 units coming back from the field.

FAQ — Bitmain APW8 16-20V PSU

Q: Will the APW8 16-20V work on an S17 or S19 series miner?
A: No — the APW8 16-20V variant is specifically rated for the S15 / T15 power envelope. S17 series requires APW9 or APW9+ (higher voltage and power); S19 series requires APW12 or APW17. Confirm your miner model before ordering.

Q: Is the second-hand condition a problem for production duty?
A: Each unit is tested before shipping. Second-hand PSUs from S15 / T15 stock are typically sourced from decommissioned farms and have remaining service life — but as with any used PSU, expect a somewhat shorter MTBF than a new unit. For mission-critical applications, request a new replacement.

Q: What voltage should I set for an S15 vs T15?
A: Both miners auto-negotiate the rail voltage with the PSU based on the miner's firmware settings — you don't manually set the PSU output. The 16.32-20.04V range covers both models' operating envelope.

Q: Can I daisy-chain two APW8 PSUs?
A: No — the APW8 is a single-PSU-per-miner design. Don't parallel two PSUs unless the original miner setup explicitly supports dual-PSU operation.

Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com for volume pricing on APW8 second-hand stock.
