Yes, I do have a Asus psu of 1000w. I'm not a gamer, I use it for editing porfessionals videos as job. Thank you!Id say bit of an extreme graphics card for that system. But if you have a good enough psu, 1000w at least, and is of high quality and case is wide enough to prevent forceful bending from the supplied 16pin adapter connecting towards case panel side of the card then you can at least try and compare games tested on Techspot to whether you need to upgrade mobo/cpu or not. Im assuming you're a gamer so, next time express your usage.
