That's awesome. I've been hoping they would come out with something. They aren't the best claimed numbers, but they are back in top contention.
Really excited to see the offering, though they may miss it with only a couple days left in the month. Great find Hagss, I'm beginning to think I need twitter to find anything out.

I wish they didn't go with integrated PSUs. I don't trust anything other than server PSUs to deliver that amount of power without being electrical and fire hazards.

Yeah, there will be a huge amount of good external psus which people can't use with their miners no more.
It seems that the 5-pin comm port, two of them, are still there in the front panel. I like that they keep the idea of having a Rasp Pi controlling multiple miners.

They came up with the two tube two fan stack for cooling pcb board is shorter easier to cool them off. Similar to bitmain, I am hoping the gear has proper down clock the A841 had good down clock ability. While the a851 and a921 did not.

I hope they get back to having true specs again. Up until the A921, Avalons always seemed to do better than their advertised specs. The A921 was disappointing on that front.

Ja. However, the integrated PSU's are a large part of the better efficiencies we are seeing from the new miners so that will remain the trend. Even the best switching regulator designs are only pushing 98% Pin > Pout eff. More common is around 94% or less so using the PSU itself to set the voltage sent to the strings of chips saves several percent power eff per-board vs using 2 stages eg AC > 12V > hash board voltage regulators > chip strings. Another bonus is that using more chips in each string allowing the higher voltages reduces the voltage differences that can appear across each chip in the string making it easier for tuning to find a stable operating voltage.

I was going to have some vanilla vodka last night I passed it by. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) If this does 31th at 56 watts a th it will do 1736 watts. The real key to it having value is the down clock say 27th at 45 watts = 1215 watts or maybe 25th at 45 watts = 1125 watts I could order 50 of these and replace the entire farm at Clifton. 50 x 1125 = 56.25 kwatts 50 x 25th = 1250 th and I would still have 18 L3+ units. I now have 570th at 50kwatts and 18 L3+ units I am eager to find out if these are good.

Ditto. After the 921' performing so disappointingly Canaan better pull a hat out of a rabbit ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) to get their reputation back. Perhaps offer some discount to those of us who bought the A921's?

I purchased 1 A921 And I tested 2 A851's Both were Simply not good in efficiency and no clocks were helpful I have always like dealing with Steve and Lilly they even sent my partner buysolar to China back in 2018. We can use a good avalon miner again. Fingers crossed that it works well. I could then write Avalon 1021 rocks on my logo ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)

I've been wondering since the SP3x days how long it was going to take people to realize long tubes don't cool very well. Looks like more than just Bitmain are noticing.
Fuzzy, I'd be surprised if the main regulators on most recent miners hit 94% and above. High voltage is good for high efficiency, but 45A in a single phase really isn't, considering two of the main sources of loss in a buck increase with current squared.
Unless their PSUs are built very cleverly, going to an integrated PSU with no board-level regulation probably means all boards run at the same voltage. If that's so, the entire machine, instead of an individual board, has to run at the level of its weakest chip. If they do have separate independently-controlled rails per board though, that's pretty sweet.

I love canaans products the most, this is kind of another let down though. Considering the m20 and bitmain now with the s17 are hitting essentially 30w/th numbers which is double in efficiency than this. I prefer canaan for reliability and I love the daisy chain setup but ugh. Unless the price is really low I don't see these selling much sadly

Specs are pretty close to the s15 and better than the m10. If they're shipping now it's well timed release.

well lets see:
m20 is 48th at 2200 watts = 45.8 watts not 30 watts these have been mentioned on pangolin m20 is 72th at 3300 watts = 45.8 watts not 30 watts
s17 is ? the 30/j = a number for the chip maybe just maybe they do 40 watts on low and 45 watts on high as a unit
a1021 is 31 th at 1736 watts = 56 watts certainly not 30 watts
the key is does it down clock to 25th at 1125 = 45 watts
if you can go to 45 watts it still has value.
if it is like the A921 and A851 where down clocks suck it will be a loser
All three units avalon whatsminer and bitmain have yet to be demoed so what's the watts per th is not sure as of now.

![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FWg62Ly6.jpg&t=665&c=yJUO7NcJ_vBLPQ) Don't you think they added the (minimum 50W/T) inside their ad for a reason? Perhaps they already tested it and could not get any better efficiency from them? 50W/T is pretty good in my opinion. Bitmain's S17 is probably 45ish but they claim 35... Only a third party review can tell.

It is important for miners to know watts per th on this gear so I contacted Steve of canaan for a demo to review. My goal is to show: S17 M20 A1021 in youtube videos as soon as I can get the gear. It will help miners pick what is best.

I dont know about the new Avalons but many of the new units including Bitmains use 20v internal rails, 12v PSUs just wouldnt power the miner properly. Its not that they are trying to force us into their PSUs, they are just a requirement for the unit to function.
