AM4 Socket

AM4 chipsets provide dedicated PCIe lanes for USB, graphics, data, and other I/O.

Personalize Your Gaming Rig

This motherboard features LEDs on the back to create a red glow inside your case. For additional lightning inside, Mystic Light extension headers are on board for controlling optional RGB strips, fans, and other gear, without needing a separate RGB controller. Additionally, Mystic Light Sync can also work with select LED-enabled keyboards and mice. Customize and set up your own color scheme with the MSI Gaming app for smartphones and desktops to match your personal style.

Cooling

MSI fan headers automatically detect fans running in DC or PWM mode for optimal tuning of fan speeds and silence. To make sure your system stays quiet, Hysteresis is also available to make your fans spin up fluently. You can also monitor and adjust your fans as needed with the Total Fan Control software.
