Pricing looks good now compared to all other options, but nearly 4 months until delivery?!

It's interesting that they list Qty 1-99, previously they did not take direct orders for small quantities so you'd have to go to one of the distributors. I wonder if that is going to change for these batches.

The email suggests that the coupons are only for "partners", so guessing they won't be given to everyone.

The prices and efficiency are on point though.

So order one for a1156 for 1265 get 56 th and a coupon
Buy an a1166 for 2055-212 = 1843 get 68 th

Cost of 3168 plus shipping 124th and you have a 212 left over coupon maybe see it for 68
Cost of 3100. This is pretty cheap. But February is a long ways off.

P.s.
I got the same email
I have gear due
Oct
Nov
Dec

I would not mind scheduling some of these for Feb and Jan

I wonder if they would allow PayPal as bitmain allowed PayPal for this last batch they put out.

Edit: no mentions on the company website yet, https://canaan.io

A small comparison with Bitmain gear (only the one available to place an order now):

S17 PRO - 50th/s - $2503 (shipping 7 days after full pay) 50$/TH; 39.5J/TH, 1975 W/h

S17e - 64th/s - $2323 (shipping in January 2020) $36.29/TH; 45J/TH, 2880 W/h

S9 SE - 16th/s, shipping in 7 days after full pay - $26.87/TH; 80J/TH, 1280 W/h

S9K - 14th/h, shipping 7 days after pay - $18.78/TH; 85J/TH; 1190W/h

What are your thoughts? Will it drive Bitmain's price a bit lower?
I believe yes and no; the Halving is coming and February delivery is so so; but I have to admit the prices are better for the Avalon gear.

And safer. I've replaced 15A outlets in hosting that were drawing maybe 8A continuous and started to melt. Asking a cable and socket to run near 100% all day for multiple years isn't very smart. A mechanically solid connection like screw terminals is one thing but a friction fit like a blade/socket is different.

Actually, my opinion, the whole extreme density concept miners are built with now is stupid. I get that it allows them to shave off some overhead percentage by increasing the total cost of the miner that is chips, but the customer is demonstrably seeing none of that savings right now. Floorspace and shelfspace cost is almost nothing compared to operating cost, specifically power and maintenance and exhaust. With extreme density comes greater need for maintenance (and greater chance of fatigue and failure and fire) and tighter ventilation (and intake filtering) requirements for the meager savings of a half square foot per machine.

To clarify sidehack

The issue is c19/c20 cable and socket rates 16amp 24/7/365

So:

16 amp x 208 = 3328 watts
16 amp x 220 = 3520 watts
16 amp x 230 = 3680 watts
16 amp x 240 = 3840 watts

this cable is well made and is one of your better choices to run the gear.

https://www.amazon.com/NEMA-L6-30P-C19-Power-Cord/dp/B004WOE85S

I have 3 units pulling 3300 to 3500 watts using those cables they are whatsminer and they downclock when my volts drop too low. my guess is this will be an issue sooner or later.

It simply would have been a lot easier to have these units use 2800 watts or even 2600 watts.

The problem isn't the noise. The problem is how much current the one power cable and its connections can handle safely. Not just that but how much they can handle indefinitely, since the machines rolling out now will need upwards of two years service life just to break even.

The funny thing is, this again, will probably not do that well due to the same issue inno, whatsminer, and now canaan all seem to be too blind to see vs bitmain. 1 power connector. Bitmain has 2 on all there miners. So bitmains miner that would be 3000w = pdu friendly, everyone else... = not friendly. This would be pretty interesting especially if price but yea, 1 connect is a no go for many of us.

If you run in a data center, they can handled the power requirements. A home miner makes it more difficult not not impossible. I am running my M20S with one C19 on lower power at 1950 W on a 20A 208 circuit. I could push it to the normal setting but then it would go to 3150 W. More noise that I can hear in my living room from the garage.

And if I was doing it I wouldn't build a machine requiring a 3300W PSU.

That would be the common sense answer lol

this is my thought. Get a 2800 pull use a c19 and no issue with a 208 3 phase supply.

I am going to order a t17 I will open psu and check its insides. I will show photos. The two plug design knows you have one plug.

Which would imply that it is a dual PSU.
If not, barring using 2 power relays wired to monitor each input and open/close the circuits (pricey & bulky) the only other way to isolate the power inputs so you don't (usually) have a live cord end when unplugged would be to use 2 bridge rectifiers, 1 for each power inlet, to give the raw DC that is fed to the switching portions of the supply. While it would mostly satisfy that safety aspect it also raises a few questionable design points regarding the current ratings of the bridge rectifiers and what happens if a portion of one shorts.

Either way, as a designer I'd go with the single high current power inlet even if it means breaking the mold of how it was done in the past. It's just the right way to do it. In my book since large farms already have to deal with the very different cases, power inputs just become another part of what they need to change.

Do the *17 miners have four boards or three? An odd number of boards would weigh against an internally dual supply.

Apparently canaan didn't get the memo though so hey whatever. lol

Or they just prefer to follow some semblance of proper electrical design (tho yes they *are* pushing the plug rating) vs winging it and letting the chips fall where they may. Wink

Same, 3200-3400w on 1 cable into a pdu is way too much. My pdu's as most are 15amps each bank as well. I don't run more than 12amps each bank, meaning 24 amps each pdu into a 30amp 240v outlet. So this one plug stuff is tiresome and the reason sales are crap and will most likely be. Whatsminer m21s, an m20s are very very easy to get, and get at a rather good price these days in stock ships today. No one wants them because most places do not want to direct plugin to wall. Bitmain knows this, and solved that issue. Apparently canaan didn't get the memo though so hey whatever. lol

'The right to privacy matters'

Single cable with 2500 watts is fine

single cable with 3220 watts is not fine for me. Clifton is 208volt 3-phase we run around 217-227 volts with a drop to 187-190 at times.

3220/208 = 15.48 amps a c19 is 16 amp for 24/7/365

but Canaan is smarter then the whatsminer's m20s that gear is 3450 watts which is not code for a c19 as

3450/208 = 16.58 amps.
3450/217 = 15.89 amps.

I have 2 whatsminer m20s so far they are good on the 208 3 phase with the one cord. they have a down clock function if the psu runs out of balls due to lowered volts they downclock the unit. every once in a while my m20s drop from 68 /69 th to 50th I have determined that happens we we get the voltage drops.

If the new cannan/avalon gear does this then it is not a big issue.

A single connector makes no difference to me. My pdu's have outlets for both c14 and c20 male ends so is piece of cake to use it with the correct c20 to c19 cordset. Of course can only power 2 per pdu though...

As I mentioned earlier in one of the BM threads, what I'd like to know is if the BM miners have 2 psu's in the 1 case as that is the only way using 2 feeds to 1 device would be permitted by electrical codes. IF those power inlets are simply in parallel with each other there are several very bad possible situations that come to mind, 1 being the male end of a cord being live when unplugged from the wall...

A reply to a question on Canaan's twitter account says the first batch will be end of January, beginning of Feb.
