IMG 4 logoWhile the Haswell-E platform is of course already associated by high price tags thanks to expensive CPUs and the use of DDR4, some people want to kick it up another notch. The WS based boards from ASUS aimed at the workstation segment bring with it a whole mess of features and a heavy price tag. Let’s see if all this can be justified today as we take a look at the ASUS X99-E WS.

Designed for users who aren’t shy to spend a few extra dollars the Workstation series of boards tend to bring with them a ton of features and massive expandability as they see more expansion slots and connectors than your typical retail board. It all starts very quickly as you straight away notice the seven PCIe 3.0 slots on the motherboard. This is only the surface of what’s being offered by ASUS, though, on the X99-E WS.

At $503; the X99-E WS is one of the most expensive X99 motherboards on the market. For that price, though, you really do see so much. Included on the board is 14 USB 3.0 ports, eight SATA 6G ports, two SATAE, one M.2 slot and two eSATA 6G jacks. ASUS also offer two Gigabit LAN ports along with the standard eight DDR4 memory slots you’d expect from a X99 motherboard.

Taking a look above we get our first look at the X99-E WS and it really is quite pleasing to the eye in a simplistic kind of way. We’ve got a black and grey setup going on with a really nice looking heatsink located in the bottom right corner of the board.

The front of the box doesn’t say much with the ASUS logo and model number shown directly underneath. Apart from the “Quad Strength Graphics Power” and “5-Way Optimization” logo we’ve got the normal array of logos across the bottom. The overall box design is very standard.

The Bundle

Inside the following accessories are included:

  • I/O Shield
  • Motherboard manual incl. driver and software DVD
  • ARS Manual
  • Quick Start Guide
  • 12 SATA cable
  • 2-Way SLI Bridge
  • 3-Way SLI Bridge
  • 4-Way SLI Bridge
  • Expansion plate with 2x USB 2.0
  • Expansion plate with COM port
  • Q-Connectors

While short of what we saw on the ROG designed ASUS Rampage V Extreme, we’ve still got a fairly large bundle here. The big difference is the ROG board is aimed for that overclocker / gamer and offers a bunch of extras that revolve around that. The Workstation series is aimed more at a professional user who doesn’t want those associated extras. If they did; they could simply opt for the ROG offering.
