You can get Canaan's products through one of their distributors, like the U.S. based Blokforge, with no MOQ.
I've ordered through them for all my Avalon equipment, and highly recommend them. Great service and
support.

Even I've bought through block forge. ... .. in the past. Wink

Edit: Been drooling at their 841 pricing actually.

I'm interested to buy this when it launches. But the MOQ and company account restriction is a bummer. If they don't solve this unfortunately my money is going to bitmain.

thus 3 with no issues on a 30 amp

I could do 9 of these at the solar array or 297th

vs 12x 841's or 162th

quite a difference.

Being new miner I was kind of confused Canaan would release the 821 and then the 841 so quickly. If their close to a 33th unit I'll be happy. Not the wife with the added db's.

Listed wattage would put you around 21.5 amps for 3 units and 14.3 amps for 2 units.

so a 30A 240v will run three?

Hmmm.

Now I have to find somewhere to Install another 30 amp circuit.

Can't wait to see if this offers the same flexibility in voltage settings. They've been a lifesaver running the 841 during the hot summer.

Maybe they'll bundle 3 together and sell them like the "moose", call it the "deer". A nice home miner setup.

That would be nice, so a 30A 240v will run three? Maybe I'll wait on some upgrades if this is the case.

Why? Is a bad idea...

Mainly so I don't have to add a switch, more controllers, cabling, and create more points of failure. I fully understand the issues with upgrading firmware and that under/overclocking settings will apply to all units. I run on default settings and currently mix 821 and 841 units without issues.

Why? Is a bad idea...
As with the 7 & 8's the miners will be using different firmware and unless ran at default settings will no doubt want different Vcore voltage/offset tweaks. Even mixing within 1 family is not a good idea, aside from the tweaks, if you update firmware ALL miners on the controller are updated to it. Trust me: a 721 does not like thinking it just became a 741.-- been there, done that and fortunately was easy to back out of. Same for the 8's. RasPi's are cheap so it is best to just take the most sensible course

yeah 3 avalon long chains are close to bullet proof.
that is 12 per rasp pi.
and a rasp pi can be built for under 80 dollars

https://www.amazon.com/CanaKit-Raspberry-Starter-Premium-Black/dp/B07BCC8PK7/ref=sr_1_1_sspa?

so pick up a few of them.
it only runs into a big expense if you go to a 1200 miner build as 105 at 80 = 8040
if you go to this level you should consider a server that does more the 4 usb ports. chains that a rasp pi does.

chains of 5 have a bit more errors then chains of 4 which have a bit more errors then chains of 3 which are close to error free.

Hopefully you'll be able to chain these with the 8's.

I have seen recent activity on the Avalon 851 firmware and guessing it's probably for this unless they are releasing a slower model first like they did with the 821. Hopefully you'll be able to chain these with the 8's.

So bitmain keeps selling the cheap s9's til ?

I'd guess that they are just waiting to shit on the competition. If they already have something similar or more efficient, they could sell it at 2x's current S9 price and still be cheaper than everyone else.

Interesting to note that 1720 watts is right up against the power limit for running (2) on a 220V 20amp circuit continuouosly.

20 amps /2 = 10 amps * 80% max = 8 amps * 220V = 1760Watts.

Nice design point!

yeah works for 10 amp circuits =rare
20 amp common
30 amp common
50 amp less common

would really like a mini version 13000gh and 850 watts but that is not going to happen.

They run at 40 c but drop efficiency 841's do this.

30c they are more efficient

but -1 or -2 settings help efficiency .

This year we had 1 hot week and my 841's ran in 92f 95f 97f 94f days with zero issues ... both the s9's and t1's dropped boards with those temps

I'm not entirely sure if this issue was resolved, but I thought it was firmware related. I've run my 841's all summer at
32°c to 41°c with no issues. Pushed high one day to 42°c and I dropped them to the -1 offset.

Either way, I'm "all in" waiting for this release. Great company!!!

Same, up to 40C here ambient with mediocre exhaust still . . not recommended though. Have to watch my PSU's not my avalons at these temps I'm seeing though summer now.

Fun day for announcements, glad Canaan will be ready for market soon. Was there word on pricing? 26-30th/s is broad range for them though. Speculation on end result and wattage?

Thanks for the break down philipma, always appreciated.

I wonder if the Avalon will still have the 30 deg C limit? Is that due to only being a single fan?
