Packaging and accessories

The B450M Steel Legend motherboard is delivered inside a regular cardboard box which shares the overall design with the rest of the Steel Legend products. The product and series names are printed at the center on the front side of the box. A couple of features are listed on the lower edge of the box with a small ASRock logo placed at the top.


The back side of the packaging presents in detail the motherboard and the main features. The upper side presents the ASRock Polychrome SYNC RGB system and the installed connectors. The right side features a top photo of the motherboard with a diagram of the I/O panel and all the connectors present. Further down, the full specifications of the motherboard are listed, next to a couple of photos with the main features of the board.


The sides of the packaging share the same overall design as the front side. The name of the motherboard and the ASRock logo are printed at the center, with two small Ryzen logos placed on the left side.


The motherboard is protected inside the box by a soft foam case, that covers the edges of the motherboard as well as the backside. The foam frame is attached to the motherboard by four plastic zip-ties. While this motherboard is a budget model, ASRock did not skimp on the internal packaging and protection.
