Frequently asked questions

How much power does the Avalon A1566I use?

This 249 TH/s version is rated at 4,500 W (4.5 kW) from a 220-277 V AC supply. A load this size is sized by an electrical engineer, not a household breaker.

Can I run the Avalon A1566I at home?

Not in an ordinary home. It needs 220-277 V AC 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 Avalon A1566I?

It is listed at 50 dB. The fans are gone; the pumps and dry cooler of the loop set the real noise level.
