ASUS TUF B450M-PLUS GAMING AM4

The ASUS TUF B450M-PLUS GAMING is a Micro ATX motherboard built for AMD AM4 socket processors. It supports Ryzen 1st and 2nd Generation CPUs as well as Ryzen with Radeon Vega Graphics. The board uses the AMD B450 chipset and provides dual-channel DDR4 memory across four 288-pin slots.

Builders Using Ryzen 1st or 2nd Gen

This board suits builders installing Ryzen 1st or 2nd Generation processors or APUs with Radeon Vega graphics. It offers one PCIe 3.0 x16 slot, one PCIe 2.0 x16 slot at x4 mode and a single PCIe 2.0 x1 slot. Users needing PCIe 4.0 support or Ryzen 3000 and newer CPUs should look at a newer chipset.

64GB DDR4 Across Four Slots

The board accepts up to 64GB of DDR4 memory over four slots with speeds up to 3200(O.C.) MHz. Overclocked speeds of 3000(O.C.), 2800(O.C.), 2666, 2400 and 2133 MHz are also listed. Populating all four slots at higher frequencies may require verified modules from the QVL.

Questions about this item

What SATA standard do the six ports use, and what is their practical speed cap?

All six SATA ports run at 6 Gb/s, so any connected drive tops out at that interface limit.

What case clearance does the Micro-ATX board and its reinforced PCIe slot require?

The board fits any Micro-ATX or larger case; the SafeSlot x16 uses a standard bracket height, so only a dual-slot graphics card could crowd the adjacent x1 slot.

How is the M.2 drive installed, and which step often gets missed?

Insert the 2242-22110 module at an angle, press flat, and secure with the supplied screw; the step people miss is that populating the slot disables the two chipset SATA ports.
