MSI B350 Krait Gaming, AMD B350 motherboard socket AM4 [7A33-002R]

The MSI B350 Krait Gaming is a motherboard in ATX format and has graphics cards with a fast PCI Express 3.0 slot with full x16 connection and an x16 slot with eight lanes. There is also a PCIe 2.0 slot with x4 connection as well as three PCIe x1 slots for other expansion cards. Up to 64 GB of DDR4 RAM take up the four RAM banks, with corresponding memory running at a maximum of 2.666 MHz. The internal connection repertoire includes, among other things, two headers for USB 3.0 and USB 2.0 for 4 ports each.

Such as SSDs and hard disks, the board is managed by four SATA 6G connectors (including RAID support), as well as a horizontal M.2 slot, which is connected to four PCI Express 3.0 lanes, enabling enormous speeds up to To 32 Gbit / s. M.2 SSDs with a length of 42 to 110 mm can be used and the advanced NVM Express protocol, which has been especially optimized for highly parallelized data carrier accesses of modern PCIe SSDs, is supported.

A small highlight on the MSI B350 Krait Gaming is that the I / O panel on the back of the motherboard has a USB 3.1 port with a type C socket as well as a USB 3.1 port with a type A jack located. The new USB type C port is particularly thin and can be plugged in at both ends. USB 3.0 or USB 3.1 Gen 1 achieves maximum speeds of 5 Gbit / s per port. A special feature is the integrated LED connector with MSI "Mystic Light" support, which allows an LED lighting to be perfectly synchronized.

Last but not least, five fans with a 4-pin PWM connector and a water cooling pump can be connected directly to the board. On the mainboard, additional devices and components can be connected to the MSI B350 Krait Gaming via USB 3.0 and 2.0, Gigabit LAN, universal PS / 2 or six audio jacks for 7.1 sound via the I / O shield. In addition, two monitor outputs are available for display via an integrated APU graphics unit (optional): HDMI and DVI-D.

CPU Cooler Compatibility Note on AMD Socket AM4:

Because AM4 (+), AM3 (+) or FM2 (+) predecessors AM4 (+), AM4 (+), AM4 (+) AMP connectors have to be matched to compatible AM4 mounting kits. CPU coolers attached directly to the motherboard's retention module are fully compatible.
