I don't know if the miner is fully functional, since I can not make it connect to the web. This is related to electricity issues in our apartment though. Running the miner through the only available power socket will blow our apartments fuse.
What kind of outlet are you plugging it into and what's it rated for? These units will only work on 220~240V outlets unless using a transformer. At 240, each unit requires a little more than 8 amps. At 120, one of these can pop a 20 amp breaker if it's not dedicated. I sold all of my Whatsminer units. Too power hungry and you won't even make a profit unless electric is $0.12 kWh or cheaper. At $0.12 you'll make $5/month profit.
