The ASUS P9X79-E WS (workstation) motherboard has a color scheme which is highly known to be used by ASUS, the black, blue and silver is almost a signature of ASUS for many years now. Some may think this scheme is a little dated, but to be honest, we think that ASUS did the right thing with this WS motherboard by sticking to what works and is popular. Also, we have to say that the impressive thermal solution and the brushed aluminum heatsink aesthetics really makes this WS motherboard stand out.

We were also quite happy with the layout of the motherboard and its features. Some of the features we found to be most attractive were the massive amounts of SATA ports available. The 7 PCIe slots and most of all the memory expansion of being able to use ECC and Non ECC memory for a full variety of memory options. This also goes along with the CPU support list, ASUS has expanded this 2011 socket motherboard to accept a large scale of today’s Intel chips.

When it comes to its software package, ASUS continues to include an abundance of software. The extensive software package that was available with the motherboard really made it stand out from other manufacturers. While we won’t see all users taking advantage of everything included, its nice to have. This was especially appreciated since this board offered quite a bit of unique features such as the Dual Intel Enterprise Gigabyte LAN ports and the SSD Caching capability of up to three SSDs and Dr Power software to enhance your experience from power failures like we see with many Workstation application builds.

For its performance, this motherboard performed as we expected. Being that this board was developed on an E-ATX format, we can appreciate the size and will fit into most of today’s standard ATX cases. So all in all, we can say that ASUS put together a great workstation motherboard in a mainstream platform. We also had no trouble with its set-up, which was a great sign. With the 4820K, we found that our 16GB 1866MHz memory was able to run at the advertised speeds with little to no work. All we had to do was enable the XMP profiles and we were set. In the OC sector, while using the ASUS AI Suite pretty much hit the sweet spot on the 4820K, manual overclocking didn’t do so bad either. This is a rare touch with more workstation motherboards and we are glad that ASUS has streamlined its mainstream overclock-ability they are known for into a WS motherboard like the P9X79-E WS.


We really didn’t find any negatives or downfalls with the ASUS P9X79-E WS motherboard. With a price tag of $469.99, we find that price is a bit steep, however if you consider the capabilities and features of the board, that really isn’t a bad deal at all for a workstation board. To find a perfect match of both features and performance is hard to beat. Because of these factors we are honored to give the ASUS P9X79-E WS motherboard our PureOverclock Editors Choice Award.





    If the P9X79-E WS only has 40 PCI-E 3.0 lanes… then how does it run 3-way SLI or 4-way SLI at x16 speeds? I thought that it had to equal the total number of lanes (i.e., 40)? So then 40 lanes would be achieved by:

    3-Way SLI: x16 +x8 +x16 = 40 lanes
    4-Way SLI: x16 +x8 + x8 + x8 = 40 lanes

    So how do they pull off 3-Way or 4-Way SLI with each card running at PCI-E 3.0 x16 speed (which would seem to require 48 lanes or 64 lanes respectively)? Am I misunderstanding something?


      Hi Archangel,

      This motherboard uses two PLX PEX 8747 chips to increase the number of PCIe 3.0 lanes on the motherboard from 40 to 72. That is how the board is able to handle the full X16 lanes on the PCIe slots.

      or respectively x16/x16/x16/x16 and x16/x8/x8/x8/x16/x8/x8.
      Sorry this information was not touched on in the review, I will be sure to update it.



    This motherboard uses 2x plx chip to achieve 4 way 16x sli , Asrock extreme 11 uses somthing similar.
