So originally thought I only got one extra power cable from the video card to the PSU. So I used that, and the other additional power connector was already on my PSU, along with others ( the gtx needs 2 power connectors ). then later in the box I found another one so I decided to use that, with both of em thought when I tried to power up, my system just went on for a second before going dead. I instantly thought the mobo was somehow fried, but once I removed both of the video card power connections and just connected the PSU connectors straight to the video card, it everything powered up and worked fine. Question is, did I do any damage the 3 times I tried starting the mobo up and it only flashing for a second?
