I've recently added a graphics card to my build (MSI GTX geforce 760) , at first it appeared to work fine and I was able to install the drivers etc. however, my computer then suddenly turned off and now I cannot get my computer to power up with the graphics card installed and it continuously shorts upon pressing the power button. After much fiddling about I've discovered that it must be something to do with the 8-pin connector to the graphics card, currently my PSU (Corsair RM750) only has one 8 pin connector which goes straight to the MOBO and the PCI-E power cable is a 6-pin/2-pin, so I'm currently connecting to the GPU via a 6pin - 8pin adaptor provided with the GPU , is this perhaps where the problem may be lying ? as without this power cable connected I am able to power my PC up however, it seems odd that it was working initially. Any help or ideas would be gratefully received.

The PSU is brand new , and when I disconnect the GPU it all powers up and works fine though. Again this is the same when the 6-8pin connector is disconnected too however, then it just comes up with the screen telling me to put the power plugs into the graphics card.The power supply is probably bad since it has low quality capacitors. Get a Seasonic 720W or XFX 750W power supply.

Apologies if some of my questions are perhaps elementary as this is my first build but I have just tried to connect the GPU with the 6-pin and 2-pin straight in as to act as an 8 pin however, it still keeps shorting out straight the way. If it is a dodgy PSU how come it will work without the Graphics card in ? Surely is it not the GPU that may have an internal issue perhaps?

Low quality capacitors aren't the issue here.

Unfortunately I'm unable to upload a picture at the moment however, I've had a quick play using different combinations and I've found that the computer will power up every time apart from when the 6pin power cable part is in the 8pin section of the gpu, but without this the gpu is essentially useless. I don't know if this is of any use to what it could be but as always any suggestions are appreciated

Can you not plug the 6+2 into the GPU and the 4+4 into the motherboard? Will that not work?There isn't anywhere I could plug the 4+4 into the motherboard ? Surely this needs to come straight from the PSU as well. Could it be that the GPU has blown or faulted somewhere because as mentioned it did initially work for about 15 minutes before it did suddenly cut out.

Look near the CPU socket. There will either be a 4 or 8 pin connector for the mobo nearby (depending on model). That's where the 4+4 EPS connector goes.
The PCI-E connector should have a 6+2 pin connector (and maybe a second six-pin connector). Plug the 6+2 into the GPU's 8-pin connector. Plug the 6 portion of it into the appropriate side, and then put the 2 pin connector into the remainder.

Scratch that, I see your problem. The MSI GTX 760 has an 8 pin AND a 6 pin power connector. Plug the 6+2 in to the 8 pin as I described above and use this adapter

to convert a molex power cable into your secondary GPU power cable. Once you get both the 8-pin and the 6-pin PCI-E power cables into your card, it will work.

Thank you for your help so far. I've already tried the above as you mentioned as well as trying the 6&2 into the 8 and a 6 straight into the 6. After trying a whole number of combinations I've narrowed it down and it appears to be the 6 from the 6 & 2 that seems to cause the system to not boot up however, I can't figure the cause for this.

I looked at your PSU and you should have 3 other PCI-E cables you can try.
When you boot, does your system power on? Does your motherboard give any error diagnostic codes? If it powers on and POSTS, does it simply hang or can you plug your video cable into the motherboard's onboard graphics connector?

If nothing is plugged into the graphics card it boots however, I cannot get anything on the monitor as I assume the mobo is going straight to the card as it detects it in the PCI I imagine. When I have the 6 pin into the graphics card , it just shows a boot screen that says 'please power down and insert other PCI-E power into GPU' . When I have the 6 pin into the graphics card and only the 2 pin section in the 8 pin connector it will boot but again I can't get anything through the monitor and with the the card's fans go on their fastest speed.

I don't think you're understanding what I'm saying.You are going to have a total of 14 pins going into your GPU. One 8-pin (the 6+2) and one 6 pin. Hook it up that way and see if it boots.
Apologies I may not have explained myself too well earlier.
I have tried putting the 6+2 pin into the 8pin on the GPU and the other 6pin into the 6 pin connector on the GPU however , with this it will not boot , my machine will just give one click and then fail to power up. With the 6 pin from the 6+2 pin connector removed everything will boot. So I presume the problem lies within this 6pin connector on the GPU. I have tried this with other 6 pin connectors I have in order to check it isn't the connector itself that wasn't working & have also made sure each time that both the 6+2 connection and the single 6 pin connection were in securely.

I've tried different cable and in different ports for both the gpu and in the psu however the result it the same each time. I've even tried it with a different psu and it's still the same therefore I must assume it's the gpu especially as it was initially working I must imagine something may have shorted or blown a fuse or something in doing so which is why it keeps shorting now perhaps? I may just have to continue with my cpu's graphics for now I guess
