Video Card Causing Restarts?

Hi everyone. I just put together a new build and I'm having an issue. When I power on, all the fans start spinning including on the video card. After about 20 seconds though it appears the system shuts down and then starts up again. After another 20 seconds it happens again and it is a continual process.

I believe my video card is causing the issue because when I remove it (or even just disconnect the power cable) the problem doesn't occur and I can then get into the BIOS using the onboard video. Is it the video card that's bad or could something else be causing it?

The card I'm using is a Sapphire R9 270 on a Gigabyte H97 motherboard, with a Seasonic 550W PSU and 8GB on RAM. Thanks.
 
Ok, I just tried putting the card in the PCI-E x4 slot and it seems to work fine. I then tried putting a different card (not PCI 3.0) in the x16 slot and that too worked. The difference with the second card though is that it's powered by the mobo and not the PSU.

What would cause a card not to work in the x16 slot but work in the x4 slot, while another card does work in the x16? I'm thinking if the issue was with the slot, the second card wouldn't have worked either.
 
Sounds like an incompatibility issue between Gigbyte board and the R9, not uncommon with Gigabyte boards.
I would use onboard video and see if you can find a BIOS upgrade. If still have issue, get a refund on one of the devices!
 
So you're saying the R9 in general may not be compatible as opposed to Gigabyte not playing nice with Sapphire - i.e. an R9 270 card by a different manufacturer will probably have the same issue?
 
Update the BIOS and don't overclock anything. Also with a new build I'd check the motherboard standoffs/connectors (i.e. anything touching it, from both sides) in case there's a short-circuit somewhere.
 
Well, I had already checked the Gigabyte website and of the two BIOS updates they show for my motherboard, neither addresses video card issues. I've contacted Gigabyte about the problem to see if they have anything to say about it. I already breadboxed the system so I doubt it's a short circuit.

Just update it to the most current bios. Load optimized defaults, set memory up to spec. Drop card in and see what happens.

Most likely Gigabyte will just instruct you to do it anyways....Why waste time?

^this x2
looking up what the bios updates fixed and waiting for a reply from a forum already wasted enough time with it. if it doesnt run with the latest updated bios its time to send it back in and get a new or different board.
