New PC build running slow with GPU installed.

Hi guys, I have just completed my first build, but I am having a hard time getting the system to run properly with the GPU installed. If I remove the GPU it all runs much better. My specs are:

i5 4690
Gigabyte Z97MX-Gaming 5
8 GB Corsair Vengeance
Asus R9 280X DCII
CX600M PSU
1TB HDD
Windows 8.1

I have installed all chipset drivers, GPU drivers (from web, not CD) and all Windows 8.1 updates available. So as far as I know, everything is up to date.

It takes a long time to boot up and games are unplayable ie, WoW is only 2-3 FPS (opposed to ~15 FPS on integrated graphics on the same settings)

The GPU shows up in device manager, so I can only assume is connected properly, which leads me to believe that it could possibly be the PSU, however I have read that the CX600M can handle the R9 280X.

Have I just got a dud card? Any feedback or help would be much appreciated. Thanks!

Thanks for the checklist, I'll go through it shortly. I didn't realise my PSU was ranked that low though.. Might be worth upgrading whether it fixes the problem or not.

Monitor is plugged into card unfortunately, I had half hoped it wasn't for an easy fix

If you've been through that checklist really carefully -

OK - now swap out pieces. Try a new power supply eg Seasonic 620, XFX 650 or Antec HCG 620M

Okay so,
after a lot of stuffing around and having parts tested, I have finally found a solution to my problem.

In the end it was a communication problem between the motherboard and the GPU.
In the BIOS there is an option to set the PCI-E ports to either Auto, Gen 1, Gen 2 or Gen 3. I found that only Gen 1 and 2 would allow me to boot successfully. Hopefully if anyone else is having a similar issue, doing this can help them!

I have a very similar set up to you:
i5 4690
XFX r9280x
8GB corsair vengeance
Cx600m PSU
Gigabyte GA H97M

I'm currently running windows 7 though. I was getting problems similar to those you described with the graphics card plugged in, with it out it was loading fine though. I changed the PCI-e ports to gen 2 and it worked! So thank you very much!!! Does anyone have an idea as to why this worked?
