Bitmain Antminer KS5 Pro Kaspa Miner

The Bitmain Antminer KS5 Pro is an ASIC miner built for the KHeavyhash algorithm and Kaspa cryptocurrency. It delivers a hashrate of 21 TH/s while drawing 3150 W of power. Four high-speed fans provide active cooling for continuous operation. The unit requires a 220–277 V input supply.

Upgrade From Lower Hashrate Kaspa Miners

This model replaces earlier Kaspa ASICs that offer substantially lower hashrate per watt. The jump is worthwhile when electricity cost and network difficulty make older hardware unprofitable. Released in March 2024, it targets miners who need higher throughput without expanding rack space.

Sustained Load Thermal Behaviour

Under continuous full-load operation the four-fan array maintains stable temperatures by moving high air volume through the chassis. The 3150 W power draw remains constant, so cooling performance does not degrade over time. Stable voltage within the 220–277 V range is essential to avoid thermal throttling or hardware damage.

Questions about this item

What are the exact dimensions of the Antminer KS5 Pro without packaging?

The unit measures 430 mm wide, 195 mm deep and 290 mm high without packaging.

Which input-voltage range must the PDU or wall outlet supply to avoid damaging the miner?

Connect only to a 220 V to 277 V AC source; voltages outside that range can damage the hardware.

How often should the four built-in fans be cleaned to maintain airflow?

Inspect and dust the four fans monthly in typical environments to keep the 3150 W thermal envelope stable.
