Whatsminer C19 16A Power Socket | 250V AC Connector for P21 / P221 / P222 PSU
The Whatsminer C19 16A power socket is the OEM-grade AC inlet replacement for the P21, P221, P222 family of Whatsminer power supplies — and an essential repair part when the original socket loosens, oxidises, or arcs under continuous mining load. Rated at 16A / 250V AC and built with welded pure-copper terminals, the socket delivers maximum conductivity and safety in 24/7 mining-farm conditions.
This is a precision-engineered repair component: the welded connections prevent loosening, the optimised 5-30N insertion force ensures a secure mating cycle without damaging the C19 cable plug, and the insulation specs (≥100MΩ insulation resistance, ≥2000V AC dielectric strength) hold up to the electrical stress of continuous-duty deployments.
High-Current Pure Copper Connector — Corrosion-Resistant & Durable PSU Replacement
- Mining-grade durability — pure copper construction ensures superior conductivity and heat dissipation.
- Secure connection — welded terminals prevent loosening under continuous operation.
- Safety certified — withstands ≥2000V AC dielectric strength with ≥100MΩ insulation resistance.
- Precision engineering — optimised 5-30N insertion force for a clean, repeatable fit.
- Corrosion-resistant — built to last in harsh mining environments and humid sites.
When to Replace the AC Inlet on a Whatsminer PSU
Common failure modes on AC inlets include visible discolouration around the terminals, intermittent arcing on plug-in/plug-out, loose mating with the C19 cable, or thermal damage to the housing. Any of these symptoms warrant replacement: a degraded socket creates resistive heating that wastes energy, accelerates further damage, and can take down the PSU entirely. The pure-copper, welded-terminal design of this replacement socket directly addresses each of those failure modes.
