So I wanted to make my pc look a little snazier with some PCIE power extenders, plug em in and decide while I am at it I will untangle the rats nest in my cases back panel.
I have a corsair 500M PSU with a single PCIE rail, and a bunch of molex Y cables attached to that powering 4 led bulbs and a water pump, with the 6+2 pin and 6 pin PCIE power cables powering my gtx 760 as far apart and as close to the main connection as possible.
This had functioned perfectly well for ahwhile now, and I had made sure all my cables were plugged in to the same spots since I redid each connection one at a time.
When I tried booting up my PC again,nothing happened. So I popped off the back panel and made sure all the connections were snug, power it on again, it posts, but I smell something funny.
A large cloud of smoke was billowing out of the other side of my computer, I immediatly shut off the power and try ripping out the connections with tears streaming out of my eyes. I look and one of the molex y cables powering one half of the 6 pin connector definetly melted good. I unplug all things attached to molexes except for my pump and the PC posts, and says on the screen please plug in PCIE cables. I do this and then the computer doesn't post.
After removing the GPU and using my intel graphics the PC posts perfectly fine and I am using it to write this post. However, when I plug in the PCIE power cables without a graphics card in the PCIE slot the computer does not work, what broke, what did I do wrong, and how do I prevent this from happening again?
EDIT: I forgot to mention the molex cables melted when the PCIE cables were unplugged from the GPU. Yea kind of an important oversight.
