I don't know It's could be another computer component. If anything it would be your Mobo but it looks ok. What GPU were you using before you got this one, or is this what you have had since you got it?

I am using r9 280x since the first card keep RMA the same card still but i tried with other card like Radeon HD7970 , no issues

You may just have incredibly bad luck, or the PSU might not fully support the current GPU?

Have a look to see if there are any drivers from another GPU installed (I know the 280x is your first card but remove all of your drivers then reinstall the drivers for the 280). It does sound like it could also be a PSU issue, gonna have a look at the specs of the CM V750s now just to check it's not that.

EDIT: just had a look and it looks ok, if you can try the card in another system to see if it's a problematic card or another component in the system, and even try a PCI-E x8 lane on your board to check if it's a faulty x16 lane.
