B550 mainboards support all features of the Ryzen processors of the third and fourth generation, especially the PCI Express standard in version 4.0 (PCIe 4.0). PCIe 4.0 is backward compatible and can be used with all expansion cards from previous generations. In addition, the mainboards support up to 128 GB of RAM with a guaranteed clock speed of 3200 megahertz. With overclocking, much higher clock rates are possible, depending on the mainboard. The B550 chipset also enables the processor to be overclocked.

The features of the MSI B550-A Pro at a glance:

1x PCIe 4.0 x16 (x16) and 1x PCIe 3.0 x16 (x4)
2x USB 3.1 / 1x USB 3.0 Type C (internal) / 4x USB 3.0 / 8x USB 2.0
2x M.2 (1x PCIe 4.0 x4 and SATA 6G / 1x PCIe 3.0 x4) / 6x SATA 6G
DDR4 memory up to 4400 MHz using OC
Ready for AMD Ryzen 3000 processors
Control of RGB accessories via MSI Mystic Light Sync

The equipment of the MSI B550-A Pro in detail:
The MSI B550-A Pro is an ATX mainboard and has a PCI Express 4.0 slot with full x16 connection plus a PCI Express 3.0 x16 slot with four lanes for graphics cards. The motherboard provides two PCIe 3.0 x1 slots for additional expansion cards. The four RAM banks support up to 128 GB DDR4 RAM with a clock rate of up to 3200 megahertz and can even handle clock rates up to 4400 MHz via OC.

Two M.2 slots are provided by the AM4 mainboard. One of the M.2 slots is connected to four PCI Express 4.0 lanes. It accepts plug-in cards up to 110 mm (22110) and supports the SATA protocol. M.2 SSDs with the advanced NVM Express protocol (NVMe) and a connection via four PCI Express 4.0 lanes support data transfer rates of up to 8 GB / s and are twice as fast as via PCI Express 3.0.

The second M.2 slot is connected to the chipset with four PCI Express 3.0 lanes and supports plug-in cards up to 80 mm (2280). Six SATA 6G connectors are also provided.

Modern connections for peripherals and lighting
The MSI B550-A Pro provides a USB 3.1 connector with a Type-C socket, a USB 3.1 connector with a Type-A connector, and two USB 3.0 connectors with a Type-A connector on the I / O panel Socket and four USB 2.0 ports (type A). The USB Type-C port can be plugged in on both sides, is particularly thin, and USB ports with this standard generally support the quick-charge function of smartphones and tablets. USB 3.1 reaches maximum speeds of 10 Gbit / s per port. An HDMI and a DisplayPort connection are available for CPUs with an integrated graphics unit such as AMD's Picasso APUs.

Furthermore, this B550 mainboard offers features such as Gigabit LAN (Realtek RTL8111H), on-board sound (Realtek ALC892 audio codec), a reinforced PCI slot for the graphics card and numerous internal headers. Also on Bo (a) rd are OC features as well as an optimized power supply and large cooling elements.

The MSI B550-A Pro is not illuminated, but external RGB components can be controlled and synchronized using the manufacturer's software. The mainboard has a 4-pin RGB header and two 3-pin RGB headers. Furthermore, a total of eight fans can be connected and controlled directly to the board.
