The wire starts to overheat with a single SP120 RGB fan attached to it via the RGB lead. When the RGB lead isn't connected to the hub but the fan is given power via just the 3pin it doesn't over heat. So basically whenever the RGB hub draws power it goes into melt down.

The hubs could be bad but one hub came in an 570x and one in fan bundle so unlikely these are the same batch but could be wrong. Correct, only the black wires are melted on both hubs - not the black and grey. All cables are for the ax850's and are all labeled as such so no incorrect wires were used. Nothing was fried other than the hub sata cable which on the first setup had a HDD and SSD connnected. Close up: http://i.imgur.com/nYKHj8f.jpg?1 http://i.imgur.com/I9UAr9w.jpg?1

Right.... so an update and the testing I've done so far as I'm still waiting for a response to my support ticket a week later. I added a new EVGA PSU and control hub to the system and did a full tear down and check of all wires. There was no sign of burning or melting on any other wires and no grounding issues could be found. 'Great' I thought and now have a fully working system. However, I decided to retest the two melted/burnt out control hubs with the old corsair ax850 PSU which was installed outside of the case. Upon testing the same issue came back with the wires of the control hub started to over heat when ever the fan RGB connecter was plugged in. No over heating of the wires happened when it was just the 3pin connected. So I thought 'well this happened on two control hubs, so must be the ax850 PSU....' well I happen to have a second ax850 PSU. So tested the second ax850 PSU and the same over heating/melting of the control hub wires happened again. Different SATA power cables were tested again. So in summary my testing leads me to believe there is some issue between Corsair ax850 PSU's and the control hub. For reference the serial numbers for both PSU's are (R1112BA1620407 Rev: A1W & R1112BA1620408 Rev: A1W. So yeah, any other ax850 owners using the control hub successfully?

The connections on either hub don't have any visible burning in person - it is just the SATA wires that have burnt/melted. I'm doing a full tear down this weekend and will be testing everything out of the case and with a different PSU so will update to let people know.

Thanks for your response, yeah I'm thinking it is the PSU too - which is indeed a corsair ax850. Strange though as the PSU is acting normal with everything else, apart from trying to send the control hub straight to hell. I'll get in contact with support and take it from there. Thanks for the help

Hey, Wondering whether anyone else has ran into this issue... Today I moved my partners system into a 570x upon starting up the SATA power cable on the hub started to smoke and melt. It had 6 fans connected to it. I then connected just two fans to a new hub and a different SATA cable and also smoked and melted. Anyone else had this issue? http://i.imgur.com/6o09c3C.jpg?1
