Recently put together a new build, reusing my titan x (maxwell) for gfx card. Everything works fine until the graphics card is put under any load, basically when loading up 3dmark or any game. Within seconds the previously near silent power supply clicks like it is constantly switching something off and on. Video below: This didn't happen in my old build with my old power supply when using this card so it does seem to be the supply. Is it normal for it to sound like this? I've never had any prior to this make much noise at all.
