AC Power Cord C13 to C20 1.5m for Antminer / Bitmain PSU
This AC power cord is a heavy-duty extension cable that mates a C20 male plug on one end with a C13 female receptacle on the other, making it the right pattern to extend power between PDU outlets and standard Bitmain Antminer power supplies. With a 3x2.5mm² conductor cross-section and a 1.5 metre length, it provides the headroom required for high-current ASIC deployments in a farm cabinet or test bench.
The heavy-duty insulation and reinforced strain reliefs are sized for sustained mining loads. Pair it with our other ASIC AC cordsets to standardise your site cabling across PDU, PSU and miner.

When to use a C13-to-C20 cord
The C13/C20 mating pattern is standard on Bitmain Antminer PSUs and most data-centre PDUs rated 15A+. A C13-to-C20 extension is ideal when you need to extend a PDU outlet to a PSU that is set further back in a rack, or to link two short cordsets together to reach the miner. Always size the cord and the upstream breaker for the full PSU input current.
Compatibility
Suitable for Antminer / Bitmain PSU AC input and any device using the C13/C20 receptacle pattern, including most rack PDUs. For miners that require the C14 male / C19 female pattern instead, see the matching C14-to-C19 extension cord in related products.
Common failure symptoms
- Loose connector causing intermittent reboots under load
- Visible burn marks or melted insulation around either end
- Voltage drop along the cord under sustained current
- Cracked strain relief at the cord-to-plug entry
- Discoloured contacts from arcing inside the receptacle
Frequently asked questions
Will it fit my Antminer PSU?
Yes if the AC input on your Bitmain Antminer PSU is the C20 male pattern. Many APW3++/APW9 and similar PSUs use this connector — confirm by checking your PSU inlet pin shape.
What is the maximum continuous current?
The cord is heavy-duty, sized with 3x2.5mm² conductors for sustained mining loads. For exact derating in your installation, check local electrical code and your PSU label.
Is it a C13-to-C20 or a C19-to-C14?
This is C13 (female) to C20 (male). For C14 (male) to C19 (female) extension, see our 15A 250V C14-to-C19 cord.
Can I daisy-chain two of them?
Mechanically yes — but each additional link increases voltage drop. Prefer a single, properly-sized cord whenever possible.
