The Radeon Xpress 200 is a computer chipset released by ATI.

The Radeon Xpress 200 comes in five different versions: The Radeon Xpress 200 (RS480) chipset can make use of different southbridges, one of them is the SB400 (IXP 400), providing 2 ATA channels (2 devices per channel), 2 SATA 1.5 Gbit/s interface (4 drives total) with RAID 0, RAID 1 and RAID 0+1 support, 7 PCI slots, 8 USB 2.0 and AC'97 codec for 5.1 and 7.1 surround sound support.
