MSI MAG B550 Tomahawk, AMD B550 motherboard - socket AM4 [7C91-001R]

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 MAG B550 Tomahawk 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 / 6x USB 2.0
- 2x M.2 (1x PCIe 4.0 x4 and SATA6G / 1x PCIe 3.0 x4) / 6x SATA 6G
- DDR4 memory up to 4866 MHz using OC
- Ready for AMD Ryzen 3000 processors
- RGB lighting with MSI Mystic Light Sync

The equipment of the MSI MAG B550 Tomahawk in detail:
The MSI MAG B550 Tomahawk 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 4866 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 GByte / 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). In addition, six SATA 6G connectors are provided for additional drives.

Modern connections and RGB LED lighting
The MSI MAG B550 Tomahawk has a USB 3.1 port with type C socket, a USB 3.1 port with type A socket, two USB 3.0 ports with type A on the I / O panel. Socket and two USB 2.0 ports (type A) ready. 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 dual LAN with 2.5 gigabits (Realtek RTL8125B) and 1 gigabit (RTL8111H), on-board sound (Realtek ALC1200 audio codec), a reinforced PCI slot for the graphics card and numerous internal ones Header. Also on Bo (a) rd are OC features and an optimized power supply.

A special feature of the MSI MAG B550 Tomahawk is the RGB lighting, which can be synchronized with other RGB components using the manufacturer's software. The mainboard has two 4-pin RGB headers and two 3-pin RGB headers. Furthermore, a total of eight fans can be connected and controlled directly to the board.
