Included with the motherboard are the regulars including; manuals, driver CDs, SATA cables and a rear I/O plate. We received the WIFI version, and you probably guessed it, it has WIFI, 802.11 a/b/g/n/ac, MU-MIMO Rx, 2.4GHz/ 5GHz (160MHz) up to 1.73Gbps Supports Bluetooth 2.1, 2.1+EDR, 3.0, 4.0, 5 which is nice. 



The board has 3 x PCIe 3.0 x16 slots which can be arranged in these slot configurations with graphics cards:

  • 1-way mode - x16 / x0 / x4
  • 2-way mode - x8 / x8 / x0
  • 3-way mode - x8 / x4 / x4

As you can see, these are PCI Express Gen 3.0 configurations, that's okay for regular graphics card setups up-to 2-way SLI/Crossfire. The motherboard comes with two power connectors 8+4. You'll get four DIMM slots that can be used for dual-channel memory. Up to 4200+ MHz supported in OC mode. Please do check compatible memory and thus the QVL (Qualified Vendors Lists).
