Smoothrunnings,
What I am talking about is that after new PSU plugin, it no worky. The Series2, 55nm units are shipping and they have 2 blades in them. You can see what they look like by taking a look around Ebay. The problem was that the GreatWall PSU is a POS and, as you might expect, could not supply enough wattage to hit the 200 – 220 Ghash mark without the machine continually restarting (I’e not enough electrons to do the job at hand). This, in turn, predicated the PSU replacement and VIOLA, burnt silicon smell (ie.. the magic smoke might have been released ...... I hope note). I've verified that both PSUs are operationally fine by bridging the green wire to a black ground wire and BOTH PSUs kicked on just fine. Thus, not a PSU problem. I’m trying to diagnose, and better yet learn from those who came before me, if that burnt silicone smell is as bad as I imagine it and *IF* I need to order myself a shiny new controller board. So, what you think?

Avalon doesn't make them. It's some 3rd party manufacture that is making them and saying they use the Avalon chipset. You have to understand that the Chinese like to compare other products to the original one. At this point in time Avalon-asic.com doesn't make a version 2 Avalon with the 55nm chips, so what your friend bought was a knock off with the 55nm chips. I looked on ebay, nothing says "made by Avalon-Asic" in the auctions. They do say they use the 2nd gen Avalon chips. I hope your friend didn't pay $5,000 for a 150 ~ 200GH/s machine, Neptune machines which are on pre-order are selling for $10k and promise a minimum of 3TH/s.
(the chips will supposedly be 20nm ones too.)
If the unit doesn't power on with the PSU and it's burnt inside likely you have likely toasted one of the controller boards it.
