Whatsminer P231B / P232B Switching Power Supply | 3300W PSU for Air-Cooled M20 / M30 / M50 / M60 Miners
The Whatsminer P231B and P232B switching power supply units are the dedicated PSUs for Whatsminer air-cooled miners across the M20, M30, M30S, M30S+, M30S++, M31S, M32, M50, M60 and M60S models. Both variants deliver 3300W rated output from a wide 220-277VAC three-phase-compatible input range, built for continuous high-load operation in mining-farm and data-center environments.
The P231B targets the 12V rail family (12V / 265A primary + 12V / 15A auxiliary); the P232B targets the 14V rail family (14V / 230A primary + 12V / 15A auxiliary). Match the variant to your hashboard's voltage spec before ordering — wrong rail voltage will not power the miner correctly.
When to Replace the P231B / P232B
- Miner refuses to start — PSU dead, hashboards stay dark with control board confirmed healthy.
- Intermittent shutdowns mid-mining — PSU rail sagging under sustained hashing load.
- Voltage instability or startup failure — PSU regulation drifted out of spec.
- Burning smell or visible damage — replace before further cascade damage to control board / hashboards.
- Fleet refit on aging M-series units — preventive PSU swap to keep uptime targets.

FAQ — Whatsminer P231B / P232B PSU
Q: P231B vs P232B — how do I know which one I need?
A: Check the rail voltage on the existing PSU sticker or the hashboard spec sheet. M-series miners running 12V rails need P231B; those running 14V rails need P232B. Wrong variant will either under-volt the hashboards (insufficient power) or over-volt them (damage risk).
Q: Will the P231B / P232B run on US 120V mains?
A: No — input range is 220-277VAC. US installations need 240V service. Mining farms running this PSU class typically have three-phase service.
Q: Compatible with hydro-cooled M53 / M56 / M66?
A: No — air-cooled variant only. Hydro miners use the dedicated hydro PSU family (P463B / P554B / P663B). Mismatch will not power correctly and risks cooling-loop disruption.
Q: Bulk pricing for fleet operators?
A: Yes — email [email protected] for volume pricing and air-freight quotes for urgent fleet repairs.
