It was easier when btc price was less, now that it is way up it brings a lot of stress..  |

Cool and helpful!  It really shows all about the psu thoroughly at the component level. |

I've encountered something similar: traffic light controllers (which is a big part of my day job) with a bad lamp switch board. The lamp switch board was disassembled, and then it's connector was cleaned and rubbed with connection grease. After that the board was put back in to the controller, and tadah' it was working ok again.  (these are the mysteries of the ITC-2 controller)The connections are always worth a while to check, when problems occur. |

I've pointed here a 0.5PH rent for about a day, and I also started up my "summer cottage heater", which gives me a constant 8TH hash during the cold winter time (it's a AvalonMiner 841 with low power firmware). Fingers crossed! Here blocky, blocky. Also, happy year 2021 guys! Lets hope this one is better than 2020. |

If you can't get sub 10 cent per kWh electricity price, I'd say forget it

Escrow is a must, especially with shady guys like this!

If you want to run a btc miner and connect it to your pc which will be on anyway, then the best choices for you are GekkoScience Terminus pod miner or GekkoScience 2Pac usb stick miner.

Just have an electrician install you a 220V outlet or use that dryer outlet (an existing 220V outlet in your house?) you mentioned.

@wndsnb Yep insects can be harmful for the gear, I've had an European wasp fly in the summer in to my DIY soundproofing cabinet and it was stuck (and dead) under the cabinet's slower rpm fan blade... So it clogged the fan but after I removed the wasp, the fan luckily started to spin ok again. |

If your S9 electricity cost is smaller than the S9 mining profit,
and you can get a reasonable ROI time (maybe something between half an year - a year) ,
then sure go ahead.
But beware, they are noisy....
And don't buy the S9k variant, it has breaked a lot.
The original S9 and also S9j, S9i models are ok.

The L3+ is a Litecoin (scrypt algorithm) miner, not Bitcoin (SHA-256 algorithm) miner. GPUs are also for altcoin mining, not Bitcoin mining. Mining at Nicehash pool is not Bitcoin mining, even though you get btc as reward. If you end up with an actual Bitcoin (SHA-256) miner, this is a good first timer guide -> https://bitcointalk.org/index.php?topic=4636521.0 |

No I havent updated firmware for the first Whatsminer generations (M1 ... M3X).

The lead time is so long that it probably makes more sense to buy Avalon 1246, which is in the same power efficiency area as T19.
Or MicroBT hardware, if it has reasonable lead time via some distributor.. (their own web shop shows all sold out).
