Hi, I recently started a build using the MSI Z97 GAMING 5 (1150 socket) and had finished it up when I started testing it.

I tested it the first time and it worked fine, but then I noticed that the GPU (MSI GTX970) had a second power input slot that I had not used, despite the system running fine after the first try.

I then changed some cables;

- I added a second VGA power cable to the right most (when installed) power input for the GPU, using the 6-pin, not the 8-pin (as the 8-pin VGA 1 was in the left slot).
- I added a sysfan-molex cable (sysfan slot 1 or 2) to plug into my peripherals PSU cable, as I had a spare fan connector for the top fan.

Following this, I plugged it in again and the motherboard sparked instantly, followed by a small orange flame. I turned it off instantly and noticed that a part of the board was blackened and that this was pretty much going to be unusable now.

I'm concerned however about whether or not I ruined any other components. The circuitry looks fine on the back of the GPU and nothing else seems to have been majorly affected in any visible way, but just wanted to know if anyone had had a similar experience?

I'm frustrated most of all because I had it working and then changed it for the worse.

It depends on whether the electrical shock jumped to other components, and cannot be determined until you test out the other components. A visual check of other components will not (necessarily) show electrical damage, but the other components may have been fried anyway.

Here's hoping that the mobo was properly designed to isolate any electrical overload.

Okay, will keep that in mind, thanks. I'm fairly certain it was owing to my fiddling with the cables or plugging something in in the wrong place after it worked the first time, so I just hope I haven't done damage to anything else.
