The CPU is powered by a 10-phase VRM, which is wired to four DDR3 DIMM slots. Expansion slots include two PCI-Express x16 (electrical x16/NC or x8/x8 depending on how they're populated), two PCI, and two PCI-E x1. One of these two is color-coded blue, and could be wired to the PEX8608, occupying its third port. Apart from the six SATA 3 Gbps ports the PCH provides, and the SATA 6 Gbps controller with its two ports, an additional controller provides two more SATA 3 Gbps ports and an IDE connector. Other features are standard issues for an MSI motherboard in this class: notably the OC Genie feature, centralized manual voltage measurement points, and support for both NVIDIA SLI and ATI CrossFireX.
