Radeon 7970 not working

Last response: in Graphics & Displays

Hello,

I have a Gigabyte GA-790XT-UB3 motherboard. Is it compatible with 7970 graphics cards?

I just tried it with a VTX 7970 x-edition and it does not power up properly, makes a weird noise. A strangled sounding beep. Power unit is 550 watts, instructions say I need 500 watts. Also have enough RAM (4gigs)

I reinstalled the old 5700 series back in afterwards and it works, so i haven't screwed up the rest of the computer.

Is this a power issue or was the 7970 simply not fitted correctly?

You should try to reinstall the card back onto the motherboard. Make sure that it is seated correctly and the power is connected to the card. The strange sounding beep you heard is your motherboard trying to tell you something. I've never heard one that sounded "strangled" before though.
Do you know the power requirements for the 5700 that was in there originally?

If the problem continues you may need to upgrade your psu.
