C14 to C19 Plug Adapter – Power Conversion for Whatsminer M30S / M31S / M50 Series
This C14 to C19 plug adapter converts a standard IEC C14 male inlet to a C19 female socket, allowing Whatsminer miners with C19 PSU inlets to connect to C14-terminated power cords or PDU outlets. Built with a fireproof nylon shell and high-grade phosphor bronze contacts, it is rated at 2,500W across 125–250V. Compatible with Whatsminer M20S, M21S, M30S, M31S, M32S and M50 series miners, as well as general PDU/UPS/server applications.
When You Need a Power Adapter
Mining facilities often have a mix of C14 and C19 power infrastructure. When your PDU outputs C14 but the miner's PSU requires a C19 input, this one-piece adapter bridges the gap without splicing cables or replacing cords. The fireproof nylon construction and tight-fit contacts ensure a secure, low-resistance connection that won't overheat under the sustained high current draw of a mining PSU.
Installation
Plug the C14 end into your PDU outlet or power cord. Plug the miner's C19 PSU cable into the adapter's C19 socket. Verify both connections are fully seated — a loose adapter will arc under load. The one-piece design means no moving parts and no failure points beyond the contacts themselves.
