Lexindar APW12 4000W server power supply

Designed for S19 mining rigs

The Lexindar APW12 delivers 4000W of continuous power to S19 full series mining machines. Its active PFC topology corrects the input current waveform for stable operation on industrial circuits. The unit omits modular cabling and multi‑12V support, so every connection is fixed at the factory. Builders who need redundant or hot‑swap supplies cannot use this model.

Upgrade from lower‑wattage server units

When an existing supply cannot sustain the S19 peak draw, the APW12 replaces it with a single 4000W source. The jump is worth it only if the rack circuit and cooling can absorb the higher thermal load. No 80 PLUS licence is held, so efficiency claims rest on the manufacturer’s internal data alone. Operators who require certified efficiency ratings must look elsewhere.

Sustained output under buffer_48114

The supply is rated to maintain full output while the buffer_48114 condition persists, rather than only in short bursts. Active PFC helps keep voltage steady as line conditions vary across shifts. Gross weight reaches 4kg and the enclosure measures 255 by 255 by 70mm, so rack density planning must account for the fixed form factor. Environments that demand modular cable routing or redundant hot‑swap bays fall outside the intended use case.
