Hello, just wondering if you can help me.

We ordered a EVGA GTX 970 for my son which he bought out of his christmas and birthday money for which it arrived yesterday. We installed it and everything was fine, but about an hour ago when i was playing Minecraft with my 2 sons, my son with the new graphics card his PC just turned off during playing the game without any warning. I have tried the PCI-Express cables (with the graphics card needing 1 x 6 pin and 1 x 8 pin).

When the 8 pin is connected the PC does not start at all but with the 6 pin cable connected only the PC starts but the graphics card fans do not spin along with no display being on the monitor.

Below are the cable steps with i have tried

just 8 pin cable connected - the PC does not work
8 and 6 pin cable - the system does not work
only the 6 pin - the PC starts ok, but as mentioned no display on the monitor.

i thought is might be either the graphics card or the power supply, but if it was the graphics card it does not explain why the PSU does not power up and no drives or the radiator fans do not spin, but you can hear a slight click as you press the power button either on the front of the case or on the start button on the motherboard. the PSU does have a test button, but again with the 8 pin cable connected the test button does nothing but if you test it with only the 6 pin cable connected to the card it starts the PSU up while pressing the test button.

PSU is a corsair AX1200i
Motherboard asus rampage black edition
EVGA GTX 970 graphics card.

Many thanks in advance.

Put in his old graphics card and see what happens.
The graphics card would need both cables to work. If a VRM on the graphics card popped (perhaps due to heat, or simply out of the occasional bad luck with a new component), you'd get symptoms like that.

The reason we have quality PSU's with internal protection.

Just connected the graphics card back up with the 6 and 8 pin cables connected and the system turned on for a split second, turned back on and the graphic card below the SLI finger sparked and started smoking!
 


Happy new year as well. I was pretty sure it was the card.
