Alongside the X99 Extreme6 for enthusiasts, ASRock has launched the X99 WS (E-ATX) motherboard for professional workstations and servers. The board uses a black PCB, blue aluminum heatsinks on the power phase and PCH areas, and gold colored caps. The E-ATX motherboard uses short screws and a thinner CPU socket backplate to allow it to fit into 1U server cases. You have ample PCI-E slots, DDR4 (and ECC RDIMMs), USB 3.0, Thunderbolt 2 (with an AIC), eSATA, M.2, and SATA III for connectivity. Power is regulated by a 12 power phase "Digi Power" design with high quality Ultra Dual-N MOSFETs, 60A chokes, 12K Nichicon capacitors.
The X99 WS also uses larger heatsinks, especially around the CPU area. The board features an Intel LGA 2011-3 socket that will accept Haswell-E or Xeon E5-1600/2600 v3 processors up to 18 cores and 160W TDPs. Eight memory slots surround the CPU socket and support a maximum of 128GB of DDR4 3200+ memory. Storage is handled by 10 SATA III 6Gbps ports and a single "Ultra M.2" slot that supports SATA III or PCI-E x4 controller equipped drives.
This worskation board takes advantage of the Extended ATX form factor to cram in additional PCI-E 3.0 slots versus the shorter X99 Extreme6. A PCI-E 2.0 x 16 slot sits directly below the CPU socket followed by the (mentioned above) M.2 slot and five PCI-E 3.0 x 16 slots. The five PCI-E 3.0 slots allow for 4-Way CrossFireX and 4-Way SLI multi-GPU setups. To take full advantage of this board, you will want to pair it with the higher end Haswell-E parts (5930K, 5960X, et al) with the full 40 lanes rather than the entry level 5820K with its limited 28 PCI-E lanes.
Using internal headers, the X99 WS supports a TPM module, two COM ports, two USB 3.0 ports, four USB 2.0 ports, and a Thunderbolt port (via an extra add-in-card). It features two CPU fan and three chassis fan headers as well.
The X99 WS features the following ports on the rear IO panel.
- 1 x PS/2
- 4 x USB 2.0
- 1 x eSATA
- 4 x USB 3.0
- 2 x Gigabit LAN
- 1 x Intel I217LM
- 1 x Intel I210AT
- 7.1 Channel Audio (Realtek ALC1150)
- 5 x Analog audio outputs
- 1 x Optical audio output
The X99 WS is available now with a three year manufaturer warranty for $323.99. The price alone pushes this board well into the professional market, but gamers can get most of the way to the WS feature-wise with the X99 Extreme6. The WS goes up against the boards like the ASUS X99-Deluxe and MSI X99S XPOWER AC.
