Hi. I purchased 4 au3 miners off of ebay. The dude I purchased them from hated them so much he gave me 7 even though I only paid for 4.

I need two power adapters. Where can I purchase the power adapters?

Also. Your miners are stupidly unstable. is there a firmware update I can do to make them stable? They can't even stay up a whole day with out turning into a zombie...
