My New Build Wont Boot Up After I have Installed My Graphics Card

Hi I'm new to this so apologies if I'm doing anything wrong. Right this is a new build computer which i have been building the last two days or so.
I originally installed all the below components into the case and tried to get the PC to boot up but it failed, so i took everything out and started again to check nothing was damaged or installed wrongly and i put everything back in except the graphics card and the computer booted up fine, so I installed windows 8.1 and installed the motherboard programs off the disk to get everything set up.
I re-installed the graphics card again and no luck, so i read quite a few other threads on this website hoping for something helpful and tired most of them out including checking the CPU or any of the pins aren't damaged, the CPU power and fans are plugged into the motherboard, updated the BIOS, installed once piece of ram and tried booting it up and they all failed.
So any help would be greatly appreciated?

Case - Phantom 410 CA-PHATM-O2
Motherboard - Asus Z87-A S1150 Intel Z87 DDR3 ATX
Power Supply - CORSAIR 750W CP-9020015-UK Bronze
CPU - Intel Core i7 4770K S1150 Ret
RAM - Kingston 16GB (4 x 4GB) HyperX Beast DDR3 2400MHz DIMM CL11
Graphics Card - 3G GByte GTX780 GHz Ed. WINDFORCE
Optical Drive - DVR-221LBK 24x SATA DVD/CD Burner
Soild State Drive - 120G SV300S3B7A/V300 120G SSD
Operating System - Windows 8.1 64bit

Thanks Josh

Did you plug the power connectors into the graphics card from the PSU?

techguy55 - before I purchased all the above items I filled out the link below with all my computer components and it came out at 459w and with my 750w power supply, I thought that would be more than enough. Regarding the calculator I suppose I don't know how accurate this is though. But do you think this could be an issue then?

RobCrezz - Yeah I plugged power connections into both of the connection points on the graphics card (it has two connection points).

And I assume when I was installed you then plugged the monitor into the graphics card (not the motherboard)?

If so, it sounds like the graphics card is faulty if you are working fine on integrated graphics.

Yeah your PSU is more than sufficient, I have seen a system of this spec running fine on a high quality 450w psu.

RobCrezz - Yeah i plugged the monitor into the graphics card connection point and tried the motherboard while the graphics card was installed and neither worked.
You reckon faulty graphics card could be the problem then?

Yup, if everything else is connected correctly and you are sure the graphics card was seated correctly (with PSU connections), then it does sound like the graphics card is dead. Try it on another computer if possible.

Intresting.

With the 780 card in if the system powers up with fans spinning, but you are met with a black screen and no bios post.

1.Let me guess you connected the 24 12v. ATX power block to the motherboard.
2.You connected both the eight and six pins from the PSU to the Gtx 780 card.

3. You connected the eight pin 12v power block to the motherboard located near the edge of the top most gold colored heat sink of the board where the plug is black 8 pin.

Oop`s forgot to plug that one in.

Ah well that provides 75w to the Pci-e card slot and without it the board wont boot when a Pci-e card is in the slot ;) . Part of the eight phase power for the board.

Click on the link bellow to see what i mean.

You next step is to connect the video cable to the mobo. Enter the bios change in the graphics settings the interface to Pci-e or Peg in the menu. save the settings before exiting the bios.

And move the video cable back to the 780 card.

Shaun o - i have connected the the 24 pin power supply for the motherboard, both power supplies on the graphics card and both connections are 8 pins. (please see picture http://cdn.eteknix.com/wp-content/uploads/2013/11/Gigab...)
Then by the 8 pin connection on the top of the board do you mean the CPU power supply on the top left of the board? Which if so, yeah i have made that connection as well.

Thanks for your response

Then you should.
Remove the 780 card.

Plug to the back of the board, boot the system, enter the bios.
And change the section where it says what graphics output device to initialize first.
Set the option to Pci-e. save the settings in the bios before exiting.

Shut the system down, and insert the 780 card.

Look at where or what the primary Pci-e slot of the board is.
And make sure the card is seated in there.
Connect the video cable to the 780.

Try that and it may boot.

The problem may be a conflict between the on board and the 780 and the board not knowing what to initialize first. You may have to manual force it via changing the setting in the bios.

The setting by default is set to auto btw.
And you can also turn off the on board in the bios if you wish.

Otherwise suspect the 780 is Doa. and Rma it.
