The B860 chipset gives you what matters most: stable performance and room to grow.

What This ASUS PRIME B860M-K Does for You

This board handles everyday gaming, content creation, and productivity without breaking a sweat. The DDR5 RAM motherboard design supports up to 128GB of memory at 8800+MT/s when overclocked. Start with affordable DDR5-5600 now and upgrade to faster kits later as prices drop. The PCIe 5.0 M.2 slot gives you access to the fastest SSDs on the market, while four SATA ports let you add extra storage drives. 2.5Gb ethernet means faster file transfers and smoother online gaming compared to old 1Gb connections. USB 10Gbps rear port and USB-C front header keep your peripherals running at full speed.

Build Quality and Connectivity

ASUS includes their 5X Protection III features—DIGI+ VRM for stable power delivery, LANGuard for network surge protection, and SafeSlot Core+ for stronger PCIe slots. The VRM heatsink keeps your CPU running cool under load. DisplayPort and HDMI 2.1 outputs support 4K@60Hz if you're using integrated graphics. Realtek 7.1 surround audio handles your gaming headset or speakers without needing a separate sound card. The micro-ATX form factor fits in compact cases while leaving room for your graphics card and cooling setup.
