  • 3150 W power draw sets clear energy budget
  • 75 dB noise level suits ventilated rack rooms
  • 8 kg weight fits standard 19-inch shelf rails
  • RJ45 10/100M Ethernet gives simple wired management

Purpose-built KASPA miner

The Antminer KS5 Pro is an application-specific integrated circuit designed to mine the kHeavyHash algorithm used by the KASPA network. It delivers a rated hashrate of 21 TH/s while drawing 3150 W from the wall. The unit targets operators who run dedicated mining infrastructure and need a single-purpose device for that algorithm.

Air-cooled thermal profile

The miner uses forced-air cooling inside a chassis measuring 430 x 195.5 x 290 mm and weighing 15.8 kg. Under normal load the system emits 75 dB of noise, a level typical for high-density rack equipment. Power draw remains steady at the rated 3150 W, so the electrical supply and cooling capacity must match that continuous load.

Ethernet management only

Connectivity is provided by a single RJ45 port operating at 10/100 M, which carries both pool traffic and the web-based management interface. No additional controllers, software licences or wireless modules are included; configuration and monitoring are performed through the built-in dashboard once the unit receives an IP address.

Questions about this item

How is the Antminer KS5 Pro installed and what step is commonly missed?

Connect the RJ45 Ethernet 10/100M cable to your router, power the 3150W unit via its PSU cables, then access the web UI to enter your Kaspa pool credentials; the step often skipped is setting a static IP or DHCP reservation so the miner does not lose its address after a reboot.

What maintenance or replacement will the Antminer KS5 Pro need later?

The air-cooling fans and dust filters require periodic cleaning; expect to replace fan assemblies when noise rises above the rated 75 dB or airflow drops enough to raise chip temperatures.

What limit appears first on the Antminer KS5 Pro during sustained operation?

Thermal throttling triggered by the 75 dB cooling system is the first ceiling; if ambient temperature climbs or filters clog, the 21TH/s hashrate will scale back to protect the ASICs.
