Questions about Elgato Game Capture 4K Pro

The one in the link is the MK2 version. The MK2 really simplified the layout of the card and made it smaller. The MK1 used two chips to interpolate a 4K signal instead of one, which made it quite hot in the PC case.

The Elgato Game Capture 4K Pro does not include a low profile bracket by default. However, you can purchase a low profile slot bracket separately, as it is compatible with the 4K Pro model.
