Component Layout

Let’s now see what all components ASUS have planned for this board.

1. 2. Digital 8-phase CPU Power VRM Section controlled by Digi+ VRM EPU ASP14051 controller and 8 x IR3556M (Integrated PowIRstage) whic is a synchronous buck gate driver co-packed with a control MOSFET and a synchronous MOSFET with integrated Schottky diode with output current capability of 60A DC each.

3. Two separate 2-Phase DRAM Power section using DIGI + ASP1103 chip for total 8 DIM slots.

4. > Intel WGI218AT G-LAN Controller

5. 16. ASMedia ASM3142 is PCIe-to-two-port USB 3.1 controllers

6. Intel WGI219LM G-LAN Controller

7. The nuvoTon NCT 6796D chip provides the super I/O functions, such as fan control and system monitoring

8. WS X299 SAGE audio subsystem is named as Crystal sound which is powered by a ALC1220 chip with 10 DAC channels, simultaneous 7.1-channel playback, independent 2.0-channel, multiple-stream stereo to front-panel outputs, and an EMI cover for purer audio quality.

Audio section of this motherboard is having some premium Nichicon Gold Capacitors for audio filtration. Whole audio circuitry is isolated from other sections to reduce any interference.

RightMark Audio Analyzer (RMAA) suite is used for testing test WS X299 SAGE audio against Asus Xonar U7 External Sound card. You can see clearly the difference between Noise level, dynamic rang and Total harmonic distortion percentage produced by on-board audio.

9. Asmedia ASM1480 PCIe bus switch chips

10. Two PLX PCIe lanes switch devices PEX 8747 for management and switching of PCIe lanes on this motherboard.

11. ASUS custom PRO CLOCK II dedicated base-clock (BCLK) generator and controller chips

12. Intel X299 chipset

13. ASUS TPU micro controller.

14. 15. BIOS Controller and Bios Chip.

17. ASUS Digi+ VRM EPU ASP14051 controller is used for two separate power sections to power two PLX PCIe lanes switch devices.

  • Lot of PCIe slots
  • Two Intel GLAN interface
  • ASUS Control Center
  • Good BCLK Overclocking


  • iKVM remote-management missing


Usually workstation build are super horse-power PC builds involving serious computing powers using something from Intel’s Xeon CPU product line with 2P or even 4P builds. But that’s not the case for everyone, now a day’s there are lot of scenarios where GPU computing power is more used than that of CPU.

Targeting these types of workstation needs, the ASUS WS X299 SAGE motherboard with Intel Core X "Skylake-X" processors supports is the best board for the money right now. Offering massive PCIe connectivity alongside lot of memory and storage support. Dual Intel GLAN interface also support teaming which combines the network links, but I thing an iKVM remote-management could have added more to the product.

Finally, when pairing this motherboard with few of the higher end GPUs like NVIDIA TITAN V, one can accelerate AI computing to many folds. So if you are in deep learning or AI and adopting GPU accelerated computing the ASUS WS X299 SAGE motherboard is the best option for you and worthy of our PC TeK Reviews EXCELLENCE Award.
