The Antminer V9 Is a Good Lower-Cost Miner – If You Have Cheap Power
Bitmain recently began selling several different miners for Bitcoin mining based on current and previous generation chips — and one of the more interesting ones is the Antminer V9. What makes it so interesting is that it’s only 4 TH/s at roughly 1,000 watts, and uses the BM 1580 ASIC chips. These were in the S7 series miners which use the 1385 chips, while the Antminer S9 (as well as a couple others) use the 1387 chips. The V9 is also very inexpensive at initial costs, at $345 for one with a MMQ of 5.
The timing of the Antminer V9 comes as interest in mining is fluctuating up and down and new ASIC miners are shipping from several companies, or are about to.
Profits for the V9 will be tight and mainly for miners who have very low power costs. The reason we decided to review this miner, as opposed to our usual newest miner reviews, was to take a look at lower-end and -cost ASICs, and where they fit with all the next-gen miners shipping soon.

4 TeraHash at 920 Watts
As usual, Bitmain packed the miner safely and it arrived with no issues.
At first glance, the V9 has the same style as others like the S9, with a dual fan setup. We did experience a failed fan in the first few hours, but once we swapped it out the V9 ran well, pulling 920 watts on a 220v line using the APW3++.
One thing we also decided to do with this miner was try something different — so we mined Litecoin Cash in order to test with other blockchains. Now, keep in mind LCC is a very divisive coin and we do NOT endorse it or any other coin — we simply wanted to test a different coin.
Let’s Jump Into the Pool and Mine an Altcoin
We used LCC MultiPools for testing the V9. Setup as usual is dead simple with the Antminer firmware, a matter of simply putting in the pool address worker and PW and save. The Antminer V9 quickly connected to the pool and started mining. The miner averaged 4.2 to 4.3 TH/s on LCC Multi Pool with little deviation.
Connecting to BTC.com mining pool yielded similar TH/s reports at 4.1 to 4.2 TH/s. While running the first day, we did end up with a problem: every few hours, all chips would turn off and go to “x” in the miner panel. We tested between pools and settings, as well as checked out the controller, boards and cables — which were all ok.
A quick message to Bitmain revealed our simple issue: the front fan was bad, it would go to 6,000 RPM and then stop after a while. We swapped out with a replacement and the V9 is now very stable.
There is a new firmware as well, one that miners have been reporting fixes instability that some were experiencing. While we did not have any instability — apart from the fan issue — it’s good to update to the latest firmware if you do. It is available in the support section here on Bitmain’s site.
Summary: Good Machine, but Watch Your Costs and Profits
The Antminer V9 is a good miner for those who have low power costs, and or just want to learn about mining with ASICs. It’s a tough sell though, in a market dominated by the likes of the Antminer S9, Avalon 821 and others like the Dragon Mint T1 — which can all run above 14 TH/s at slightly higher power draws than the V9.
The build quality is good (as to be expected) other than the one quirk of the bad fan. This was the first miner in a long time that we’ve had any issues with, as manufacturers have honed their quality control to higher standards over the years.
The Antminer V9 ran very well with a stable hash rate. There are so many different SHA-256 coins to mine that is was also a good miner to test on them, instead of just sticking with Bitcoin. Profitability will be tough with it using 920 watts at 4 TH/s though, unless you have super cheap or free power. Overall it’s a good miner, even if it does belong to an older generation of ASICs.
Now that we’ve seen a bit of what the V9 can do with last generation chips, contrasted with the current generation using the S9 and Avalon 821, we will quickly review several new-gen miners of several types in the coming days. Stay tuned.
