Great news

Yan will be sending me an avalon6 replacement board.  Not free of charge which is fair since I burned it from my stupidity.

He did give me a discount for running the group buy. 


So to all avalon6 owners  do not use a psu with more then 12.5 volts  and when you check the gui make sure it is under 12.3 volts


I want to thank Yan for the replacement part in advance.

That is some master packaging Phil !

I just opened the box ;-)

make sure you don't throw a space character into the address at the end

Not sure Kilo,  when I was testing via the EVGA which connects the S7 to my 120V outlet to my Wemo Insight, it was showing pulling 1540W at the wall.  I would assume the EVGA G2 1300W efficiency rating is similar to the IBM PSU or worst as the 2KW PSU is not Platinum.    So if I use 1540 x 90% which I doubt the IBM PSU is that efficient = 1386W x 3 =4158W.  Seems overloaded to me but I don't have any tools to measure wattage for my 240V line.

Also I think your math above may be off by 1 digit perhaps typo or close key, but 1290W at 93% efficiency from Bitmain info x 3 S7 is 3870W.  These PSU are no where near 93% and even if they can get 90% they're at 100% load.  I think people are saying these are somewhere in the high 80s range efficiency right?  That would make it way over.  I'm running them now and the garage is plenty cold so it's not an issue right now, but concern when spring / summer hits.
