Bitmain APW12 PSU for Antminer 19 series

This Bitmain APW12 power supply unit is built for Antminer T19, S19 and S19 Pro miners in the 19 series. It accepts 200-240V AC input at 47-63Hz and delivers two DC rails: 12V-15V and a tighter 12.2V-12.4V output. The unit measures 254.6mm x 251.6mm x 63mm and weighs 3.6 kg.

Replaces failed or ageing APW12 units

Swap this in when an existing APW12 fails or shows unstable rails under continuous load. The jump is worth it if your miner restarts under load, if voltages drift outside 12.2V-12.4V, or if you run 24/7/365 and cannot absorb downtime. Keep spares on site to avoid lost hashrate when a unit dies.

Direct slide-in replacement for 19 series

Installation is a direct slide-in: remove the old APW12, insert this one, reconnect the same cables and power on. What usually goes wrong is forgetting to verify 200-240V mains before powering up, or seating the connector incompletely so the 12.2V-12.4V rail sags. Noise sits at 45dBA under load.

Questions sur cet article

What are the exact dimensions of the APW12 so I can confirm it fits my Antminer S19 rack?

The unit measures 254.6mm deep by 251.6mm wide by 63mm high and weighs 3.6 kg, matching the standard 19-series chassis bay.

How do I connect the APW12 to mains power and what is the common wiring error?

Wire the IEC inlet to a 200-240V, 47-63Hz supply with proper earth; the frequent error is omitting the ground connection.

Which components of the APW12 typically need replacement after continuous 365-day operation?

The internal cooling fan rated at 45dBA is the primary wear item; keep a spare PSU on site for immediate swap.
