Hi, I have a EVGA PSU. A 750 watt 80+ gold Supernova G3.
 
My apologies if this is submitted in the wrong place but I have done some research and there's not much information out there on this particular issue on the corsair forums besides some people saying oh maybe it's something to do with the PSU.
 
I've built my PC over a year ago with barely any RGB in it and now recently I've ordered 6 Corsair LL120 with a commander pro and an rgb hub.
 
I set up the RGB hub with the 6 rgb fan pins in it, a rgb header (this cable came with the commander pro) connecting to the Commander pro (I have used the Commander pro before hand while waiting for the RGB hub to come and the fans worked fine, they spin but just no RGB). The problem is when I turn on the PC the wires for the RGB hub and the rgb header shorted out and there's alot of smoke. The wires were melted basically. I can send photos on request.
 
I have returned the RGB hub and got a new one, to make sure that it wasn't a faulty RGB hub, and the same thing happened again.
 
I have no idea what the solution is and I kinda refuse to take my PC apart to read the serial number on the PSU to register to ask tech support.
 
If anyone has experienced this issue and figured out a solution or know what the problem is, please help me out.
 
Thanks for reading

    Sounds like the units are grounding out on the case when you mount it or the pins may be coming out of the plugs and crossing maybe. How old is that psu and what psu did you have before it? What is the rest of your pc's parts?

    Im sorry man, i dont have too much more to add at this point really. For 2 of the same hubs to do the same thing means either its the install or its the way the units are hooking up to your rig. Maybe the wiring pinouts need to be switched in the plug cause they have them opposite of your setup. Ive seen that a few times over the years.

    What RGB hub do you have?..That sounds like it may be the (compatibility) problem.

    I would take out/disconnect the RGB hub and just connect stuff to the Commander PRO and then install the latest iCUE software (if you get that far) that controls it..Roll from there.

    definitely something wrong somewhere , if two burnt out  in exact same rig....  I guess only way to test would be to use a different rgb hub brand & see if a different company version does the same thing ...?

    Is the wires for the PSU the stock wires or the individually sleeved cables? I suggest pulled the part number of the wires from your order if they are not the stock cables that came with the power supply.

    Sounds like a connection between Hot & Ground somewhere in your circuit (short)
     
    Not all RGB is compatible - some is 5V & some is 12V - they Can be wired differently also (location of Ground, Hot & color control are located)
     
    List the part number of the RGB hardware, fans .....  all listed by the Mfg as compatible ?
     
    Where is the RGB power from the "commander pro" or the Hub ?
     
    Check the PSU plug with a standard voltmeter ... using SATA power ? 
     
    The output (device side) of any PSU wire should conform to the standards.

    The PSU side of the wires is custom to that PSU model - Never mix wires between PSUs without checking compatibility First

    A PSU can't cause a component to short out.  A "short" is a physical thing.  It indicates is a physical mechanical problem with the component itself.  If you have tried multiple components of the same brand and model, perhaps you should try a different brand or model of RGB hub.

    When using the Corsair RGB hub and Commander Pro you must make sure that the cables are in the correct order. For the Corsair hub I believe you have each slot labelled 1 to 6. If you have four cables connected to the hub then you need to populate slots 1-4 (not 5 and/or 6). The Commander Pro is the same.

    The Commander Pro connects to power and also to a USB port on the motherboard. The Commander Pro then gives you two USB ports to use.

    The Corsair RGB hub has a SATA connector and another cable and both must be connected.

    Sorry I forgot about this thread,
    Response to rjohnson11: yeah I'm pretty sure I connected the rgb fans to the rgb hub 1 to 6 filled all of the slots for it with the rgb labeled pins. The rgb hub and the commander Pro are indeed connected to each other with the rgb header cable that came with the commander Pro and both are powered by sata

    Response to bob16314: currently I have returned both of rgb hub to amazon and still have the commander Pro, so the fans does spin since its controlled by that (with 3 fans for the aio connected to the aio header separately) and no problems so far and it's been about over a week maybe since I've set it up like this. Just no rgb lights D:
    Also the rgb hub is by corsair, the commander Pro is corsair and the fans are corsair

    Some people are saying it may be a short, how do I check for a short? (without finding it out the hard way lol)
