Apart from the User Guides and Driver CD, the ECS P55H-AK is packaged with four SATA cables and three SLI connectors, but it also comes with a 3.5” bracket for two USB 3.0 ports. This is thanks to the extra NEC chip, one of which provides two USB 3.0 ports on the rear I/O panel. Speaking of which, the ECS P55H-AK also has two Marvell SATA3 chips which provide two SATA 6Gb/s chips on the board and two more eSATA 6 Gb/s ports on the rear panel as well.
