yes grab those 821's they are decent gear. good price. they use 100 watts a th

so 11 of them is about 100th and uses 240kwatts at day

Aren't they 11.5th @ 1200W?
Or these are another marketing numbers?

Where can I get a good deal of the 821s with bulk order?

Newer gear has a second issue all the psu's are bespoke ie they must be a perfect match or they do not work.

the Avalon 821's do not have this issue. any 1600 watt or larger 12 volt psu should be good.

This is a very helpful info. I really didn't know this, since I have been reading about old gears they seem all familiar with the 6-pin connectors.

Side thoughts.
I have found that some gear is more temperature sensitive then others.

This might be a small problem for me as the temperature in summer here reaches upto 47 degrees. Celsius. Yes you read it right. But I think I can compensate it by adding an AC if the swamp coolers don't do a good job (but I think they can do a pretty job) I got a friend which has a mixture of gear like s9, L3++, and some s19s. I would be doing the same cooling setup, but the thing is according to the datasheet of the avalons, their max temp is rated @40 degC, while the bitmains are mostly 40.

Bitmain / Whatsminer are more plug and go. Avalon which I do like better and do find more reliable does tend to require a bit more setup knowledge.

Do you mean like the array connection of the miners using the AUC3 cables, AUC3 converters, and the controller? Or are there more to it?
