Mining PDUs built for the newest Bitmain hardware often have P33 outputs. The miners themselves, like the S21 family, have P13 inputs. Plenty of farms bridge that gap with an adapter. It works, but every adapter is another joint carrying thousands of watts, and joints are where heat builds up.
The Valiant Power P33 to P13 Mining Power Cable skips the adapter. P33 on one end, P13 on the other, one continuous cable in between.
P33 vs P13 in plain terms
- P33 is a 6-pin connector commonly found on the output side of mining PDUs.
- P13 is a 4-pin connector found on the power inlet of newer Antminers.
They do not fit each other directly, which is why you need either an adapter or a cable like this one.
Why a direct cable is better than an adapter
- Fewer connection points. PDU to miner is two connections instead of four.
- Less heat risk. Every contact point adds a little resistance. Under a constant multi-kilowatt load, that resistance turns into heat.
- Cleaner racks. No bulky adapter blocks hanging off the PDU.
- Locking connectors. Both ends lock in place, which matters with fans shaking everything all day.

Compatible miners
Antminer S21, S21 Pro, S21 XP, S21+, and other miners with a P13 inlet. Pair it with a PDU that has P33 outputs. Check both ends before you order.
Picking a length
- 3 ft: PDU mounted on the same rack as the miner
- 6 ft: typical rack layouts
- 10 ft: PDU at the end of a row
Use the shortest length that reaches without strain. Slack near a miner's exhaust gets hot and blocks airflow.

Frequently asked questions
Do I need an adapter with this cable?
No. It connects a P33 PDU output directly to a P13 miner inlet.
Will it fit an older S19?
Only if that unit has a P13 inlet. Check the label by the power inlet.
What does UL SJT mean?
SJT is a UL cord jacket type: a thermoplastic jacket rated for hard service use. It is a common, durable choice for equipment power cords.
