ASUS Prime B560M-K

The ASUS Prime B560M-K is the most basic of the Prime series models, with a very minimalistic looking PCB, and focuses on just the basics. The design follows the typical Prime series black and silver color scheme, including a patterned PCB and a small silver power delivery and chipset heatsink pairing. ASUS also cuts down the memory slots to two from four on the other Prime B560 models. It is however advertising an 8-phase power delivery and requires a single 8-pin 12 ATX CPU power cable to provide power to the processor.

Located in the center of the board is a single full-length PCIe 4.0 x16 slot, with two PCIe 3.0 x1 slots sitting beneath it. For storage, the ASUS Prime B560M-K includes two M.2 slots with one operating at PCIe 4.0 x4 and the second at PCIe 3.0 x4/SATA. There's a total of six SATA ports, which all include straight-angled connectors, and allow for users to install RAID 0, 1, 5, and 10 arrays. In the top right-hand corner are two memory slots, with support for up to DDR4-5000 and a total capacity of 64 GB.

Although we don't have an image of the rear panel at the time of writing, we know the ASUS Prime B560M-K includes one HDMI and one D-Sub video output. It also hasthree 3.5 mm audio jacks powered by a Realtek ALC897 HD audio codec, as well as a single Intel I219-V Gigabit Ethernet controller. There's a PS/2 combo port for legacy peripherals, while the board also has four USB 3.2 G1 Type-A and two USB 2.0 ports.

    Rocket Lake CPUs have 20 PCIe (4.0) lanes off the CPU. This a departure from previous generations in terms of lane count. Comet Lake (and older) for Intel have 16 lanes off the CPU.

    4 of those lanes are connected to the "first" m.2 slot of B560/Z590 motherboards. 10th gen CPUs don't have those lanes even as PCIe 3.0. Previous generation motherboards have all their m.2 slots using lanes connected to the chipset.

    Thanks for the explanation. My AMD X570 has PCIE 4 lanes from both CPU and chipset, so this is my first build wheres I'm running up against this limitation. Now it all makes sense and fortunately, I did place my Samsung 970 EVO into the 2nd M.2 slot. Thanks again! And old dog CAN learn something new!

    There are three typos in the first paragraph that Word or a browser would catch if you took 10 seconds to check. Hint: words need spaces between them.

    Guys, witch one I should choose between ASUS ROG Strix B560-I Gaming WIFI and MSI MPG B560I Gaming Edge Wi-Fi?

    There is no sound through HDMI ports regardless of the OS; Linux, Windows. Definitely not a multimedia board, and neither it is for gaming.

    After messing about with this board all day trying to get RAID working I find out it doesn't support RAID at all!!!

    Hi Gavin, will the M.2_2 (marked ultra m2) use the pcie lanes from chipset ? Or would it use the pcie lanes from cpu ?
