The Maximus IX Formula comes in a large box which is typical of most ROG products, it contains no preview window.
The accessory bundle is larger than you'd usually find with most motherboards due to the motherboard's feature-packed status.
ASUS provides a number of stickers and documentation items, including a 20 per cent discount code for CableMod RGB strips. Accessories included with the Maximus IX Formula are 6 SATA cables, an RGB conversion cable (GRB to BRG), CPU installation tool kit, bracket/stand for the vertical M.2 slot, WiFi Antennae, ASUS Q-Connector for the front panel cables and a pair of M.2 posts and screws for installing M.2 devices.
