Cooling

To help keep things cool, the B450M has multiple fan headers that support both DC and PWM modes, so you can control their speed within BIOS or a third-party software to find a perfect balance between noise and cooling.

Storage

Aside from six SATA ports, this motherboard is also equipped with a single M.2 slot, which supports both PCIe and SATA interfaces, for speeds of up to 32 Gb/s when used with an appropriate drive. Moreover, all AMD B450 motherboards come with AMD StoreMI technology, which is a software designed to increase system responsiveness by caching frequently used data to your SSD or RAM.

Memory

There are four memory slots supporting up to 64GB of DDR4 RAM at speeds of up to 3200 MHz when overclocked. It also supports ECC memory; however, compatibility varies by CPU.

Audio

The Prime B450M is built with Realtek ALC 887-VD2 8-channel HD audio, LED illumination, audio shielding, dedicated PCB layers, and premium audio capacitors to deliver an immersive listening experience for all types of applications whether you're using speakers or headphones.

Lighting

Aside from the built-in LED-illuminated audio section of this motherboard, it also has an Asus Aura Sync RGB header that you can use for other RGB-compatible products to light up your build.

Graphics

For Ryzen processors with integrated Radeon Vega graphics, this motherboard has HDMI, DVI-D, and VGA ports you can use to connect a display. Both DVI-D and VGA supports up to a max resolution of 1920 x 1200 at 60 Hz, whereas the HDMI interface can reach up to 4096 x 2160 at 60 Hz.
