P33 - P33 AC Power Cord Cable for Antminer T21 Bitmain Power Supply

P33-to-P33 6-pin AC Power Cord for Antminer T21 Bitmain Power Supply

The P33-P33 AC power cord is the dual-end cable used to connect a PDU (or another T21-class power supply) to an Antminer T21 Bitmain power supply. With a P33 6-pin plug on both ends and a heavy-gauge construction of 3 × 12AWG + 1 × 14AWG conductors, it delivers stable AC power across the full operating range of the T21 PSU while minimising voltage drop and connector heating.

Compared to the single-end P33 cord (PDU-hardwire variant), the P33-P33 dual-end variant is the right choice when you are running mining gear from a power distribution unit fitted with matching P33 outlets, or when you need to daisy-chain through a P33-compatible accessory.

Specifications

Installation guidance

Switch the PDU breaker off before connecting the cord. Align each P33 6-pin plug to the keyway on the T21 PSU input and the PDU outlet, push both connectors in fully, and confirm there is no gap between the connector body and the housing. The cable carries the full miner load, so route it away from sharp edges and avoid coiling tightly around other AC lines to prevent inductive heating.

Compatibility

Designed specifically for the Antminer T21 and the Bitmain power supply family that uses the P33 6-pin AC input on both ends. It is not interchangeable with single-end P33 (hardwire) cables, with P13 4-pin cords used on APW12 / APW17, or with the C20 input cables used on earlier APW7 / APW9 PSUs. Send a photo of the AC input on your PSU and PDU outlet if you are uncertain.

Common failure symptoms

• Miner powers on intermittently or reboots under hashboard load
• Discolouration or melted plastic around either P33 plug after extended use
• Loose seating between the plug and the PSU input housing
• Warm or hot cable run during normal mining operation
• Voltage drop at the PSU input compared to the PDU output reading

Frequently asked questions

What is the difference between P33-P33 and the single-end P33 cord?

The single-end P33 cord has a P33 plug on the PSU side and a bare termination for hardwiring into a breaker box. The P33-P33 variant has a P33 plug on both ends and connects directly to a P33-equipped PDU.

What is 3*12AWG+1*14AWG?

The cable bundles three 12AWG conductors for the live phases and one 14AWG conductor for the ground / earth lead. The heavy gauge keeps voltage drop low at full T21 load.

Can I use this cord on a 110V circuit?

Confirm the T21 PSU input range before connecting. Most current Bitmain PSUs require 220-277V AC; the cord itself is rated for high-current AC use.
