MSI X299 SLI Plus motherboard comes in a full black cardboard box. Looking at the front of the box, we see MSI logo with motherboard model no. At the rear of the box, we find that MSI goes into great detail on the specifications of the motherboard.

Inside the box


Board is a solid build in the mate black colour theme.

Removing Heat-sinks

MSI used aluminum heatsink in this board with plastic cover over it and RGB LED installed inside. The base of heatsink is having thermal pad installed.

I/O cover is just a plastic cover.

Component Layout

Let's now see what all components MSI have planned for this board.

1. 2. 8-phase digital power controlled via IR35201 is IR (International Rectifier) PWM Controller IC driving pair of Nikos PK632BA and Nikos PK616BA as the high and low side MOSFETs with four more driving set which are located on the back of the motherboards alongside four phase doublers ICs making the whole 8-phase VRM section.

3. Two 2-Phase digital memory power supply section

4. ASMedia ASM1074 a four downstream ports USB3.0 HUB Controller

5. Intel i211AT Gigabit Ethernet controller chip.

6. 11. ASMedia ASM3142 a USB3.1 Controller

7. Intel i219v Gigabit Ethernet controller chip.

8. nuvoTon NCT6795D SuperIO chip monitors temperatures, voltages and other key metrics for normal operation

9. MSI Audio is powered by Realtek ALC 1220 120dB SNR HD Audio - The ALC1220 is a high-performance multi-channel High Definition Audio Codec with up to 120dB SNR for crystal clear audio along with premium quality CHEMI-CON audio capacitors for a warmer sound and OP1652 op-amp as buffer.

A semi-transparent line on motherboard separates the whole audio section from the rest of the board in order to minimize interference. So listening under Stereo mode produces high audio quality with excellent dynamic range.

RightMark Audio Analyzer (RMAA) suite is used for testing MSI High Definition 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 MSI High Definition audio

  • Dual Intel G LAN
  • Not too much RGB lighting
  • Thermal shield for M.2
  • Stable OC


  • Plastic cover over I/O and especially audio section don't have any metallic tape on inside for suppression of any interference.


MSI has done a good job with MSI X299 SLI Plus motherboard by giving all of the essential features needed for a good X299 build and you don't feel like you are missing anything. The board don't have too much of RGB lighting just RGB LEDs on heatsinks and a single RGB header, whereas mostly all high end latest generation boards are full of RGB LEDs, which is good and makes this board stand different.

At the price tag of Rs.23K (approx) the MSI X299 SLI Plus motherboard is one of the most affordable yet feature packed X299 motherboards available currently.
