First custom build - All is well apart from nVidia GTX 760

Hi,

Building my first custom PC.

It boots into BIOS when the nVidia GTX 760 is unplugged.

When I disable internal graphics, and plug my GTX 760 in, there's a POST beep but no display (its fans spin though).

I wanted to double-check my power supply wiring...

The nVidia card has two power connectors: A 6-pin connector and a 6+2 pin connector.

I have a Corsair PSU cable that is like this: 6 pins on one end, and two times 6+2 connectors on the other two ends.

I plug one end of the PSU cable into the Corsair, and one of the 6+2 into the nVidia 6-pin, and the other 6+2 into the nVidia 6+2 connector.

Please confirm whether this is right or not.

Documentation for installing this card seems non-existent. Any other suggestions are welcome.

Have you tried re-seating the graphics card. It sounds like your power is right but maybe the graphics card isn't completely seated in the slot. Make sure that the sliding clip on the end of the PCIe slot is correctly holding it.

Also, what size power supply do you have?

what brand gtx 760 is this? if it is Asus or MSI, it will definitely come with the install manual.

Thanks everyone for your replies.

@Chemosh013: I have re-seated it and made sure the PCI3.0 connector clicks. My PSU is 750W, which is something like 33% over-specced based on nvidia's recommended requirements.

@invisibleian: I'm using a Gigabyte Windforce GTX760 on a Gigabyte motherboard. The graphics card has only come with a CD and a slip of paper with instructions equivalent to 'screw it in and plug everything in'.

Two questions came to mind...

-It's a brand-overclocked card, on a non-overclocked i7-4770 processor. Could this be the source of the problem?

-Only the motherboard has a DVB connector, and that's what I have connected all the time. So when internal graphics are disabled, does that mean the graphics card takes over on that DVB port, or is the DVB port completely unusable (i.e. I need to be plugging my monitor into the graphics card)?

There's the culpret! You have to plug the monitor into the graphics card. The motherboard connector is only for the integrated video. When you have dedicated graphics, that takes over so you have to plug it directly into the video card.

The overclocked video card on a non overclocked computer doesn't make a difference.

Hope that fixes it. Good luck and congrats on your first custom build. Building PCs is a learning experience that can be very rewarding and very frustrating. I just recently built one after many many years without a PC and forgot to plug in the CPU power. Wouldn't boot and took me about 15 minutes to figure it out!

Chemosh013,

Thanks very much for your reply. I had just fetched a VGA-DVI-A adaptor and to my relief the display lit up.

It would have been much more challenging if it wasn't for the wealth of information online (here!) and the informative contributions of those like yourself. I'll never look back to buying a pre-built PC!
