I just bought a new Radeon R9 270 graphics card and a Corsair RM550w PSU. With the graphics card plugged in no display come up on my monitor then after a few seconds my computer switches off then back on again. I don't get this problem with the integrated graphics. I have messed around with different BIOS settings but to no luck. The only two solutions to this that I can see is my power supply is not strong enough of I have a faulty graphics card. One of the minimum requirements for the GPU is a 500w PSU. Mine is 550w so is that too close? Should I return the GPU? Need a quick answer!

It's hard to tell. Perhaps you can test by disconnecting any optical drives and any secondary hard drives and see if it boots. Disconnecting these drives might change the power needs somewhat.

I have a Radeon 260X card with the same problem. I would not work on my primary or secondary desktops. But, when thrown into my OLD backup/test PC it works fine.

Good luck

Unplugged all drives but with no luck again. Should I just try and get a refund then?

But then is could be the PSU, or is there any chance my motherboard is too old?

Thought I would come back to this encase anyone else was having this issue. The problem was my motherboard BIOS was not compatible with the GPU. The PC maker, Advent had not updated the BIOS. However the motherboard maker, Foxconn had. I could of tried to update the BIOS using Foxconn's new BIOS update however the BIOS I had at the time was OEM so there was a chance I could of bricked it. So I spoke to Microsoft because I wanted to upgrade my motherboard but not loose my OEM licence. They said that would be fine so I then upgraded my motherboard and Microsoft reactivated my Windows licence. Everything is not working perfectly.

Also I upgraded my PSU to 750W to give me an extra bit of room to play with.
