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.

    Still limiting overclocking on mid-range boards even though the competition doesn't? Shame Intel, shame.

    Do you really need to overclock though? Don't these cpus overclock themselves to 200w+ anyway?

    just adjust the turbo limit time or enable MCE if you can, at least i think you can on b560 not sure and 2933/3000 mhz memory isnt the biggest deal either

    The most recent crop of Intel CPUs 1) overclock on their own, and 2) don't have any thermal headroom.

    Really, getting a Non-K with a B-series motherboard and saving the money for (any) GPU is the better idea...

    Not that the work isn't appreciated, but I think you should just hire raisonjohn and call it a day. His work on a massive comparison spreadsheet for the AMD A, B and X motherboard is amazing, and light years ahead of anything I've seen.

    Decent stack range, but the vast majority have too many SATA and not enough m.2 and not enough USB type C ports. In the next few years there will be more and more type C equipment to plug in.

    Apart from that, most of them are good for final DDR4 boards as a final home for DDR4 RAM as DDR 5 starts coming in next year (or the year after).

    With AMD’s reduction in CPU power the way seems open for some low power desktops to run entirely off USB-C with its power supply of up to 100w (delivered via DC so equal to a wall supply of maybe 130w AC as the transformer losses are in the wall wart not in the desktop PSU). That could mean smaller and cheaper desktops, powered straight from the monitor (if it has a USBC power supply) through the USBC video cable. Apple already has this setup though a few hoops need to be jumped through.

    Limited m.2 is mostly down to being mATX and budget. The smaller board size combined with m.2 being attached to the board itself doesn't leave much room for a 2nd slot unless you go with some sort of riser setup. And using a riser crashes into being budget products.

    USB-C rollout has been strangled by the decision to implement reversibility by adding an extra chip between the physical port and controller whose job is to swap the IO around instead of offloading that to the controller. Adding an extra dollar or two to the BOM per port has resulted in all the board makers deciding that not having multiple C ports is a good way to cut costs.

    Lastly, mATX is going to be the last place we see SATA numbers shrink as long as Intel keep offering them on their chipsets. The plugs are dirt cheap, and unless you're building a maxed out full ATX board the chipset has more IO lanes than you can use. If numbers ever start dropping below what's offered in the chipset it'll either be on mITX boards that are badly space constrained or full ATX ones where the designers decide a few more PCIe lanes or USB3 ports would be more valuable.

    Plenty of AMD micro ATX boards have 2 slots, you just need some intelligent board design. Hell they can fit 2 on mini ITX without riser boards.

    Thanks Dan for the reply. I didn’t know that info about the USB-C extra chip causing issues. USB-IF strikes again!

    Gigabyte also has the (full size ATX board) B460 HD3:
