You got everything working now, right?
More or less, the Cube craps out after about 20-24 hours, but a quick hard reboot gets it going again. I've been mostly away over Christmas, so haven't had a chance to have any more time with the Cube to figure out it's idiosyncrasies. I'm going to split the load of it between the two supplies I have and see if it stabilises things.

I did sorted mine cx750 problem...apart that wasnt psu fault.
Simple proxy issue. When i used wifi on laptop to supply work(proxy) for cubes and HTC phone was connected and wifi was on on it all was working below 30Gh/s.
Once laptop is connected to wifi without HTC in the network cubes hashing easily 32-38Gh/s both on same psu.
Temp is on average 40 celsius.
Any one else issue with 2 cubes on one psu?
No joke I had this problem with the HTC phone for weeks and weeks and thought it was so weird every time my girl came over everything crashed I was like maybe they don't like her hahaha but I set up a VLAN for her WIFI only and now not a single problem.
HTC phones use some of the ports that the Proxy uses.
