Between generations

ASUS Prime B450M-K II is an updated version of one of the most affordable motherboards with the AM4 socket. There are practically no changes in the design, but the volume of the BIOS chip has been increased to ensure compatibility with all Ryzen processors, from the 1000th to the 5000th series, without the need for a firmware update. The power supply system is designed according to the 4 + 2 phase scheme: four are responsible for the processor cores, and two are for the integrated graphics. There are no radiators on the VRM.

Overcompensation

The board has only two RAM slots, but supports frequencies over 4000 MHz and a total capacity of up to 64 GB. The M.2 NVMe SSD and x16 video card slots operate on the third generation of PCI-Express, due to the B450 chipset. However, support for new PCIe 4.0 video cards is partially compensated by Resizable BAR technology, which helps use video memory more efficiently.

Digital or analog

There are three video outputs for connecting monitors: digital HDMI and DVI, as well as analog VGA. The only thing missing for complete versatility is DisplayPort. If necessary, the integrated video core can be overclocked by several hundred megahertz via the Precision Boost Overdrive menu. But what can really be considered a drawback of the Prime B450M-K II is only one connector for a case fan.
