Description
APW17 1215a Power Supply Unit (PSU) – High-Performance Mining Power Supply
APW17 1215a Power Supply is a robust, high-efficiency industrial-grade power supply unit (PSU), fully aligned with Bitmain’s official specifications for their APW17 series. It is designed specifically to power high-performance air-cooled ASIC miners, such as the Antminer S21 and S19j XP series.
Product Summary & Key Specifications
Category
Specification
Notes / Relevance
Model / Version
APW171215a (Version A)
Standard model for most high-power air-cooled miners.
Input Voltage
220-277V AC, 50/60Hz
Requires a dedicated 220V+ circuit. Standard 110V outlets are incompatible.
Primary Output (OUT1)
12-15V DC / 267A Max
Delivers main power to the hash boards (approx. 3.2-4.0 kW).
Secondary Output (OUT2)
12.3V DC / 18A Max
Power control board, fans, and auxiliary components.
Total Combined Power
~3500W+
Sufficient for demanding miners like the S21 (≈3500W).
Efficiency (Power Factor)
>0.99 at full load
Excellent efficiency reduces energy waste and heat.
Protections
UVLO, OCP, OTP, SCP
Comprehensive safeguards: Under-voltage, over-current, over-temperature, and short-circuit.
Operating Temp.
-20°C to 40°C
Critical: Ensure ambient temperature stays below 40°C for stability.
Noise Level
45 dBA
Noticeable but typical for a fan-cooled PSU of this capacity.
Dimensions & Weight
254.6 x 251.6 x 63 mm / 3.9 kg
Compact, industrial form factor.
APW17 1215a Compatibility & Critical Connection Notes
This PSU model is primarily compatible with:
Antminer S21 (Standard/Hyd.)
Antminer S19j XP
Antminer KS5 / KS5 Pro
Antminer AL1 / AL1 Pro
⚠️ Version Alert: The APW17 comes in different versions (e.g., A, C). Your “Version A” is optimized for the miners listed above. Other models like the Antminer S21 XP or S21 Pro typically require the “Version C” model, which has a different voltage output range. Always verify your miner’s exact PSU requirement to prevent damage.
🔌 Connection Warning: The APW17 uses a proprietary C20 to 4-pin (P13) power cable. It is not compatible with cables from older PSU models like the APW12. Using an incorrect cable will prevent operation and is a safety hazard.
⚠️APW17 1215a Operational & Purchasing Guidanc
For safe, stable, and long-term operation, please consider the following:
Environment is Key: This PSU is rated for up to 40°C (104°F). Inadequate ventilation in mining sheds or garages can easily cause overheating, leading to thermal throttling or failure. Prioritize strong, consistent airflow around the PSU and miner.
Power Infrastructure: A stable, dedicated 220V/20A circuit is mandatory. Voltage fluctuations below the 185V low-cutoff will trigger a shutdown.
High-Altitude Limitation: The specification states an operational altitude under 2000 meters (≈6560 feet). At higher elevations, reduced air density impairs cooling, which may cause derating or overheating.
Buy from Authorized Sources: To guarantee authenticity and warranty coverage, purchase from Bitmain’s official store or authorized distributors (e.g., Apexto Mining, reputable local resellers). Be aware of purchase limits on official sites.
Warranty Expectation: New units typically come with a 6 to 12-month manufacturer’s warranty. Most used/second-hand equipment is sold “as-is” with no warranty.
