MSI has not revealed their complete X99 lineup yet but the X99S XPower AC seems to be their top-end offering with an E-ATX form factor. As other X99 based motherboards, it comes with LGA 2011-3 and eight memory slots for quad-channel. It supports up to 128GB of DDR4 memory. The CPU power delivery system includes 12 phases which get their power from dual 8-pin EPS power connectors. As this motherboard is overclocking oriented, it comes with loads of overclocking aids like 8-layer PCB, Military Class IV and DARK capacitors with lifespan of up to 10 years.

As for PCI expansion capabilities, the X99S XPower AC comes with five PCIe x16 Gen 3 slots for multi-GPU support and one PCIe x1 slot. The slot layout is good for up to 4-way GPU configurations. Furthermore, there is a 4-pin molex power connector near the PCIe slots which provides extra power to the slots. For storage connectivity, the motherboard comes with six SATA III ports and two SATA Express ports along with several USB 2.0 and USB 3.0 ports. The board is also fitted with Audio Boost 2.0 and Realtek ALC 1150 adding to the audio capabilities of the motherboard.

Lastly, as expected, the X99S XPower AC will come loaded with overclocking features like OC Genie, Power On/Off, on-board voltage adjustments buttons, BCLK adjustment buttons and V-Check on-board voltage monitoring panel. Furthermore, there is a diagnostic LED on the top right corner.

As for aesthetics and cooling, the X99S XPower AC comes with the black and yellow theme that we’ve seen several times in last couple of years. It has four heatsinks cooling the CPU VRM, PCH and other components. These heatsinks are interconnected with a heatpipe.

The MSI X99S XPower AC along with other X99-based motherboard and Haswell-E processors will be launched on August 29, 2014.
