Description

The ASUS PRIME B450M-K11 comes with everything you need to get started.

Despite the fact that this is a mATX board, it is considered fairly complete. You’re pretty much set with a 4+2 phase VRM configuration, 2 USB 3.1 Gen 2 ports behind, an M.2 slot that supports both SATA and PCIe 3.0 x4 interfaces, and a USB 3.0 front header.

You only get two DIMM slots, but that’s fine because you can still use dual-channel memory configurations. However, in order to keep the price as low as possible, there is no heatsink over the VRMs. It’s an important component, but it’s not as critical as other components that were missing from the board.

With the exception of the PCH heatsink, the rest of the layout is fairly simple, and can be considered naked because bare components are used on the PCB throughout the board.

For your GPU requirements, we have a PCI Express 3.0 slot running at full speed (x16). The slot itself has ASUS SafeSlot Core support technology, which means it has improved retention force and shearing resistance. As a result, you don’t have to be concerned about removing the GPU. Yes, it is a legitimate concern, as demonstrated by an unfortunate user who tore out the entire slot when removing a GPU. ASUS PRIME B450M-K11 also included an LED light that breathes when the slot lock is activated.

Two PCIe x1 slots are located beneath the 16x slow. Users are left with only one expansion slot because the first slot is most likely blocked by the GPU. The M.2 slot is located next to the PCIe x1 slot; however, if you’re using an Athlon, it will only support SATA mode. We were stranded and it took some time to figure out why.

ASUS PRIME B450M-K11 RAM

We have two RAM slots here, and you can use dual-channel configurations to get the most out of your Ryzen. The maximum support speed varies depending on the processor, but ASUS PRIME B450M-K11 claims a maximum of DDR4-4400 with this board. Because we are reviewing an Athlon 3000G, we ran our RAM at 2666 MHz, even though the RAM is rated for 3200 MHz.

There isn’t much to see at the back of the motherboard because it’s clean and only has the standard AMD backplate.
