Questions about ASUS TURBO GeForce GTX 1080 8G

You should make sure that your power supply offers enough power, otherwise it should work without problems. Then you can count on about 2x to 2.5x more performance in games with this card compared to your old one.

Hoi Johann, Stagow is right to a certain extent, it depends on what you already have in there. Could be a bit tight with 300 W. I have a dual Xeon board with 2x 12 kernel processors, 128 GB memory, 2x raid adapters and said graphics card, with water cooling and run on approx. 310 W. So theoretically it should work for you, if necessary you can also change the power supply. Greetings Marcelall

Since it is only a single radiating fan, you can assume that it will always be running and that it will also become noisy under load.
