Product Description
The Antminer KS7 is an air-cooled kHeavyHash ASIC miner from Bitmain for Kaspa (KAS). This 45 TH/s version is listed at 3,465 W, an efficiency of 77 J/TH.
As an air-cooled machine it relies on its own fans, so it needs a steady supply of cool intake air and somewhere for the hot exhaust to go. Plan ventilation and noise before the unit arrives.
Before you order
- Power: 3,465 W, about 14.4 A at 240 V. Size the circuit for a continuous load and check the input voltage on the unit before you plug it in.
- Noise: listed at 75 dB, so plan a space away from living areas.
- Algorithm: kHeavyHash. Read how Kaspa mining works.
- Released: May 2025.

Frequently asked questions
How much power does the Antminer KS7 use?
This 45 TH/s version is rated at 3,465 W, about 14.4 A at 240 V. Size the circuit for a continuous load of that size.
Can I plug the Antminer KS7 into a standard US outlet?
No. It needs 220-277 V AC single-phase input, so a standard 120 V outlet will not run it. Have an electrician install a 240 V circuit rated for a continuous 3,465 W load.
How loud is the Antminer KS7?
It is listed at 75 dB. At that level, plan a garage, basement or dedicated room rather than a living area.
What coins can the Antminer KS7 mine?
It mines kHeavyHash, the algorithm used by Kaspa (KAS). It does not mine Bitcoin.
Does the Antminer KS7 come with a warranty?
Yes. This listing is for a new unit with a 30-day limited warranty from Bitminers, starting on the date of delivery. A manufacturer warranty may also apply. See our Warranty Policy.
