Good To hear as I hope to be able to pick up some more of the Compac Fs and the hub.  I purchased a computer supply to power it.  I am thinking of eventually having two hubs and 4 Compac Fs per hub.

I am using a sipolar hub and it is ok.  I have 3 units in it and getting between 800 and 900 GH/s total.  Sometimes up to 1TH/S.  When I put in 1 Compac F my usb meter showed over 3A.
