MSI launched its Intel Z97 chipset-based Gaming series lineup with three ATX motherboards, the Z97 Gaming 3, the Z97 Gaming 5, and the Z97 Gaming 7. The company now made a high-end addition, with the Z97 Gaming 9 AC. Built in the standard ATX form-factor, the board is filled to the brim with features targeted more toward high-end gaming PC builds, than professional CPU/memory overclocking. It still offers a decent overclocking feature-set. To begin with, the board draws power from a combination of 24-pin ATX, 8-pin EPS connectors, and uses a 16-phase VRM to condition power for the CPU, which is wired to four DDR3 DIMM slots, and three PCI-Express 3.0 x16 slots (x8/x4/x4 when all three are populated, x8/x8/x0 when two are, and x16/x0/x0 when one is. 3-way SLI and CrossFire are supported. An EMI shield covers the rear-panel I/O, while another shields the entire onboard audio circuitry, and the NICs. Audio is care of a 100+ dBA SNR DAC, which an external headphone amp circuit, ground-layer isolation, audio-grade capacitors, and EMI shielding. Wired connectivity is handled by Broadcom's newer Killer E2205 gigabit NIC. Wireless connectivity is handled by an Intel-made chipset that offers 802.11 ac WLAN, and Bluetooth 4.0 connectivity. Storage connectivity is devoid of SATA-Express, but features eight SATA 6 Gb/s, and an M.2 slot. Overclocking features include voltage measurement points, and POST LED display. Expect this one to go for over US $200.
