AM3+ has nothing to do with Intel… That’s the CPU socket and an AMD cpu socket at that.
If your board has pcie slots that’s what you need to know, if it was a custom build PC they should have given you at least a parts list and manuals when you bought it.
This is a 1x pcie slot card that will fit in any pcie slot 1 to 16x in length. If you connect the usb header you also get Bluetooth if you OS supports it. This is just one of the smaller cards in a pcie adapter I have one in my laptop of the same model and it does work with recent versions of haiku. Not it only works a n speech currently not ac as the driver hasn’t added ac support yet.
