vidfail Posted January 5, 2013 Share Posted January 5, 2013 Just some background info... Yesterday I was putting together a computer for my brother, and everything was going fine. The case itself was a pleasure to build in, lots of room. First, I tested all the components outside the case to make sure everything worked, and they did. After everything was in the case, and the front I/O connected, pressing the power button produced a billowing cloud of white smoke and a smell of burning rubber. I powered the motherboard in an external build afterward and found nothing wrong with any of the main parts. In fact, the motherboard was posting correctly even as the computer was smoking. However, one of the cables leading from the I/O to it's molex power plug was partially melted. The psu doesn't have a molex connector of course, so I used a molex to 6-pin power cable to connect it to the psu. Oddly, only the cable labelled "2" on the front I/O molex plug was melted, while the cable labelled "1" was completely undamaged. Did I plug something in wrong? There was no documentation describing where or how the molex cable should be plugged in, so I assumed directly into the psu. So, is the I/O defective? Or do I need to buy a new one? Thanks.

Toasted Posted January 5, 2013 Share Posted January 5, 2013 If the PSU doesn't have molex connectors i'd suggest you buy one that has a molex connectors. The Molex to 6-pin power adapter is for two molex connectors from the PSU. You can get a replacement I/O panel here. http://www.corsair.com/us/carbide-500r-case-front-i-o-panel-all-cables-and-connectors.html Link to comment Share on other sites More sharing options...
vidfail Posted January 9, 2013 Author Share Posted January 9, 2013 Sorry for the delayed response. And I think I explained this badly... haha. I meant that the PSU doesn't have molex connectors coming from the unit itself (modular). The PSU did come with 6-pin to molex power cables, which is what I used. I guess I uploaded a picture of something entirely different, because I assumed they were all the same...lol Multiple molex plugs leading to a 6-pin psu plug, right? Anyway, we decided to just buy a new front I/O. It's pretty cheap, and I figured it would get here several times faster than any RMA attempt. Hopefully it goes better the second time around... Thanks for your help. Link to comment Share on other sites More sharing options...
Toasted Posted January 9, 2013 Share Posted January 9, 2013 What PSU do you have? Link to comment Share on other sites More sharing options...
vidfail Posted January 9, 2013 Author Share Posted January 9, 2013 Seasonic 560W http://www.newegg.com/Product/Product.aspx?Item=N82E16817151098 Not an especially cheap PSU I thought. I can't imagine it would "over-volt" something... or whatever a bad PSU does. As I said, everything else in the case turned on fine, and the motherboard was even posting while smoke came out of the case, lol. http://forum.corsair.com/v3/showthread.php?t=111217 Looks familiar... :sigh!: Link to comment Share on other sites More sharing options...
Kalec Posted January 9, 2013 Share Posted January 9, 2013 I think you messed up. That molex to 6pin is for video card. The 6pin goes into video card. You do not plug that 6pin to the PSU. Link to comment Share on other sites More sharing options...
Toasted Posted January 9, 2013 Share Posted January 9, 2013 He didn't mess up, He put up the wrong type of picture. It's a modular cable, not a GPU 2x molex to 6-pin PCIe. I would double check if the connector is in the correct port on the PSU before powering any other molex powered device. Link to comment Share on other sites More sharing options...
GTXJackBauer Posted January 9, 2013 Share Posted January 9, 2013 These guys have valid points over here. You might have accidently (as most modular PSUs have 6 pin for "peripherals+sata" and for "GPU+CPU") inserted the 6-pin into the "GPU+CPU" port when powering that molex to the I/O interface. Its also possible that the I/O was faulty and you did everything right. Link to comment Share on other sites More sharing options...
vidfail Posted January 13, 2013 Author Share Posted January 13, 2013 Thanks for all the responses! I'm absolutely sure I plugged the cable into the "Peripherals" section of the PSU. In any case, hopefully we'll receive the new I/O panel by the end of the week. Whatever the result, I'll be sure to report back - good or bad.

vidfail Posted February 6, 2013 Author Share Posted February 6, 2013 We finally got the front I/O. It took awhile, but it turned out it was on back order for a couple weeks. The important part is that it worked, no melting wires or clouds of smoke. I used the same cable, so the old I/O panel had to be faulty. Oh well, my brother's computer is now up and running.
