That's a cool story hardware -wise  , but using that miner pretty much requires 'free' electricity nowadays. |

Cool, looking forward to hear more from both you and buysolar. |

Remember that Kodak tried to offer their own bitcoin mining ASICs which were simply a rebranding of bitmain ASICs?
Wrong. Kodak rebranded WhatsMiner M3 miners as their own 'Kodak KashMiner' miners. |

HP Common Slot series (DPS-1200 FB A for example) server power supplies are very robust and usually quite reasonably priced.
But you need to know what you are doing and buy some additional supplies if you use a server power supply in a GPU rig.
The DPS-1200 FB A will have a reasonable noise level if you are not having a 100% power capacity load.

Wow, that is sad that they deleted my post. At least it wasn't a shadow delete, as I can see it missing now. I guess an official reseller of Canaan deemed my post, which is pointing out a possible fire hazard to clients, as off-topic and needs to be deleted. A reply of yours, quoted below, was deleted by a Bitcoin Forum moderator. Posts are most frequently deleted because they are off-topic, though they can also be deleted for other reasons. In the future, please avoid posting things that need to be deleted. Quote I noticed on both the Canaan website and Blokforge that the heat ranges have been lowered by 10 degrees Celsius. It use to be 40, and now it is 30. https://bitcointalk.org/index.php?topic=2616205.0I didn't get an email about this, and this much of a change would put several miners and farms out of range for this. Usually that would result in a recall or notification as the norm has been 40C for most miners up until now. Unless it was a self-moderated topic, your post was deleted by -ck or frodocooper. I agree that the deleting and modifying topics here at the hardware section has lately maybe been little too aggressive than needed. |

Just wait for Steven's reply,
I think that he will answer pretty quickly and might even come and post here at the forum.
I will let you know when I know more.

Deep In The Mines and Parallelminer.com are legit web shops too.
And ASICPuppy.net
And also of course Myrig.com, but I'm not sure if they are shipping the goods from the US or outside like Hong Kong for example.

I sent an email to Steven, let's see if they have some lab test info or etc. which could help to specify the A841 technical specs more accurately.
|
|
|
|
|
I think that they should test it some more and be as accurate with the specs as possible.
I think it should be possible to class it as a A1 class or A2 class device.

EDIT: This is now sold, the thread is closed and locked.
This is now reserved to a buyer, I'm waiting for a confirmed payment.

So the question is if Halong Mining is now having same kind of delivery schedule issues as Innosilicon has had in the past.
|
|
|
|
|
It means that the miner will stop hashing if it overheats, to protect it from damaging itself.

I'm still waiting to hear from them about a possible compensation for the highpriced A5.
|
|
|
|
|
Yeah, the current price for A3 seems to be quite reasonable if you use a 200USD coupon.
Did you try using a 200USD coupon for a A3 miner?
|
|
|
|
|
I think they are following the ETH price with each of these miner price changes.

Hassfin I know you got a miner from them for free and in exchange you did a review.

This is not true, I paid for the BW-L21 miner plus psu, and only after that Ronald sent me the gear. BITMAIN killed this little company ..  Definitely not dead, I’ll have something quite interesting in a few weeks  That is exciting news! Thanks for sharing. Loving the one Moonlander2 stick that I bought. |

Yeah thumbs up for the Sanyo Denki fans, they're great. |

I'm still pissed that they sold first A5s at 10000USD and they don't think they did anything wrong in first place.
It is my worst miner investment ever, I don't think I'll ever make any worse decision than buying a A5 unit.
I haven't received any compensation.
I haven't received any coupons.
Nothing.
Same story with us. Sorry to hear it happened to you too. If Innosilicon really cared about creating long term customer relationships they would have treated us differently. They knew that delay would cause us to never become profitable on those machines as difficulty shot up. Yet they would rather keep that one time sale/money and screw those customers never to have them to return. Maybe it's a cultural thing and they just don't have the same view of customer service as we do in the US and other parts of the world. All I know is I recommend my customers and friends to steer clear of Innosilicon because of what happened to me. The premium we paid was BECAUSE of the early delivery, not because the machine itself would be worth that long term. Their failure lost many customers for life I'm sure including me. Our risk was/should have been a DASH price collapse or unexpected difficulty increase before and following on-time delivery, not the delivery time itself. The delivery timeline was their responsibility and failure. Maybe they are making the right business choice though. There's so many newcomers to the space they might not need sales from previous customers to support themselves? They replied me via pm here, but I am still waiting for the follow up, whether there will be any compensation or not. |

Yep,
components inside an energy meter are not rated to withstand higher current than the nominal current at nominal voltage.
