I recently bought a new AMD R9 200 series and a corsair HX1050 power supply with it. After installing these i have run into to problem of my system hanging or the screen blacking out.the problem was not there pre-installation of card and power supply. The problem is removed when the card is removed, although when placed in a different box the card works as it should. I'm afraid of there being a problem with the power because the fan never turns on even past the 20% load required. I don't know if this would be a problem with the power supply or the board not pulling the required power. At first I figured it was bad drivers, but i have done everything i could think of in terms of software. I'm currently running windows 7 ultimate.
