Specs:

  • Algorithm: SCRYPT (Coins Mined: Litecoin, Dogecoin, etc.)
  • Hashrate: Over 500 MH/s
  • Chip: 288 BM1485 ASIC chip
  • Power use: 800 Watts
  • Processor: Texas Instruments AM335x 1GHz ARM Cortex-A8 Microprocessor

The Review:

The Antminer L3+ is a SCRYPT ASIC mining device by Bitmain, featuring four hashing boards with 72 BM1485 chips each totaling 288 chips. It has an advertised hashrate of over 500 MH/s, though my personal device has typically been hashing at over 510 MH/s. The device uses 800 watts through an APW3++ Power Supply Unit (PSU). At the current hashrate, each device can generate just over $450.00 US a year, excluding pool fees and electricity cost, which can be quite expensive due to the large power draw. 

For most, this isn't a miner that can be run at home, as the Antminer L3+ features two large and very loud fans, and can also get quite hot. According to forums, the device can reach between 75 and 95dB. For rerference, a hair dryer can reach about 90dB, so before you consider buying it, think about what having a hair dryer constantly turned on sounds like...

As of now, the miner is no longer profitable unless you have access to extremely cheap or free electricity. The miner can be found on retail sites like eBay and Amazon, sometimes going for under $80.00 US with the PSU! The device is no longer in production, but is quite common and is easy to find online. Though it seems like it's a great deal, be wary that at 800W, this machine can consume well over $50.00 US of electricity every week depending on your electricity cost. Also, second hand machines typically do not have any warranty, so beware of possible breakdowns, dead chips, etc.

In general, I wouldn't recommend an average crypto enthusiast to consider purchasing the device due to the power consumption, noise, heat, and low likeliness of ever breaking even. It also isn't a small machine, and often requires additional cooling. However, if you have access to extremely cheap power, and don't mind the sound of a hair dryer turned on 24/7, maybe the Antminer L3+ is a possible mining opportunity. 

Disclaimer:

I am not in any way affiliated with Bitmain or any other crypto/crypto-related company. I personally have two of these devices initially purchased directly from Bitmain in about early 2018, and one is occasionally operating though both are fully functional. It is powered by an APW3++ power supply unit. 

Remember, investments in cryptocurrencies are like any other investment: Invest only what you can afford to lose. No investment is a guarantee.
