MicroBT WhatsMiner M76S+ (390Th/s)
Immersion cooling
Description
At roughly 5200W, M76S+ (390Th) delivers up to 390 TH/s for SHA-256 Bitcoin mining with a clear facility footprint.
Electrical planning is straightforward here: approximately 5200W under load, so density and cooling can be modeled in
advance.
First released in Dec 2025, it’s commonly evaluated as a step-up path from earlier-generation SHA-256 hardware.
Immersion compatibility is geared toward dielectric-fluid systems where heat removal and density are the main
constraints.
As a M70 Series unit, it aligns with other WhatsMiner machines used in professional BTC mining environments.
Product pages include hashrate, power, cooling type, and key specs so you can pick the right unit without guesswork.
It’s a sensible pick when you want measurable output, manageable infrastructure requirements, and a WhatsMiner that
slots into a mixed fleet.

Frequently Asked Questions
Customer Reviews
Upgraded my entire farm to these units. The efficiency improvement was so dramatic that my ROI on the upgrade will be under a year.
Had to replace a hashboard after 2 months. Warranty covered it but the downtime cost me. Working fine now but that initial failure left a bad taste.
Average at best. It mines but the fan noise is louder than I expected. Might move it to the basement.
Average performer. Does what it says on the box but nothing extraordinary. Power consumption is a bit higher than I expected.
The customer support team is amazing. I had a question about optimal settings and they provided detailed, personalized recommendations. Above and beyond.
Best mining investment I've made. Quick ROI compared to my previous rigs. The build quality is top-notch and the cooling system works great even in summer.
