Frequently asked questions
How much power does the Whatsminer M66S+ use?
This 318 TH/s version is rated at 5,406 W (5.4 kW) from a 380-480 V AC three-phase supply. A load this size is sized by an electrical engineer, not a household breaker.
Can I run the Whatsminer M66S+ at home?
Not in an ordinary home. It needs 380-480 V AC three-phase power and an immersion tank filled with dielectric cooling fluid, plus a pump and heat exchanger; it does not cool itself out of the box. Plan it as a facility installation and read our guide to immersion cooling.
How loud is the Whatsminer M66S+?
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 Whatsminer M66S+ mine?
It mines SHA-256, so it can mine Bitcoin (BTC) and other SHA-256 coins such as Bitcoin Cash (BCH). It works with any SHA-256 pool; see mining pools explained.
Does the Whatsminer M66S+ 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.
