https://bitcointalk.org/index.php?topic=1727100.msg17876458#msg17876458This is a review of my experience with the M20S 65 TH miner by MicroBT. This miner is built using 12nm chips and comes with a built-in PSU. I have allowed it to run monitored for a few days to get a good baseline for power consumption. The average temperature for the environment would be approximately 27 degrees Celsius.
Real Performance VS. Advertised Performance
This model boasts an advertised efficiency of 48 W/TH or .048 J/GH @ 65TH +/- 5% drawing 3120 W +/- 10%
Real world tests came in within spec as can be seen above. I am seeing 65 TH @ 3232 W giving us an efficiency of .0497 J/GH
This is a pass for the M20S model, it delivers as promised.
Ease of useInstall
55555555555555555555555555 | It doesn't get much easier to set up than this. You are responsible for 2 connections.
The first being the network cable which connects to Ethernet port.
The second is the power cable. The miner requires a cable with a C19 connector on the power cable.
I used a 12 gauge cable rated to 20 amps - Pictured is the supplied cable
Note you will need to ensure you have a circuit within spec for the PSU.
This means a minimum line voltage of 200V and maximum of 260V.
Confirm your particular models specs as PSU's may change. |  |
Login and ConfigurationOnce you've accessed the miners IP on your network you will log in using these credentials - Username - admin, Password - admin.
Select the "Configuration" tab and then select "CGminer Configuration" from the drop down menu. Here you will enter your preferred pools information as provided by them. There is a power mode tab - Low Power function is not available at this time. I will update this if it becomes available.
NoiseThis Miner is louder than anything I have run before. Using an App on my phone I received ~ 68 db near the miner on the inlet side. Readings taken from the Exhaust side were spiking as high as 78 db. A more accurate meter would be useful, but if you want to use this in a residential environment you need to consider sound proofing. It can be done as evidenced by my setup, but I would not recommend running this in a residential or home capacity without a plan for the noise.
Packaging and Physical SpecsThe miner arrived in standard packaging for MicroBT miners. I saw no damage and everything felt secure as I tilted the machine to listen for loose or damaged components. It is larger and heavier than the M10's but overall has a similar appearance. See images below for unpacking.
My personal opinion - Overall I am pleased with this miner, and would buy another of the M20 series. It delivered on spec, and on days that have gone above 30 degrees Celsius I haven't had any issues. I am disappointed that it didn't have the Low Power mode available with this batch, and hope it will become available. On the warm days I mentioned it would be nice to have the ability to change the power mode.
