Asus Prime B550M K Argb Motherboard

Build a vibrant and reliable AMD system with the ASUS Prime B550M-K ARGB motherboard. Designed for AMD Ryzen™ 5000, 5000 G-Series, 4000 G-Series, and 3000 Series desktop processors on the AM4 socket, this micro-ATX board utilizes the versatile B550 chipset and supports affordable DDR4 memory. Furthermore, it offers key features like PCIe 4.0 support (with compatible CPUs), dual M.2 slots, comprehensive cooling controls, and integrated Addressable Gen 2 RGB headers managed by Aura Sync, making it a great value choice for budget-conscious builders seeking performance and aesthetics.
Reliable Foundation & Cooling
The Prime B550M-K ARGB provides a stable platform thanks to ASUS 5X Protection III, incorporating features like DIGI+ VRM for precise power control, LANGuard for network protection, Overvoltage Protection, and SafeSlot Core for a reinforced primary PCIe slot. Consequently, your components are well-protected for dependable operation. Cooling is addressed with an aluminum heatsink design and multiple fan headers, controllable via the Fan Xpert 2+ software within AI Suite 3, allowing you to balance cooling performance and noise levels.

Unlock the potential of compatible Ryzen 5000/3000 series CPUs with the primary PCIe 4.0 x16 slot, offering double the bandwidth of PCIe 3.0 for modern graphics cards. (Note: Ryzen 5000 G/4000 G-Series processors operate this slot in PCIe 3.0 mode). The board supports up to 64GB of DDR4 memory across its two DIMM slots, with speeds reaching up to 5100MHz when overclocked.
Storage, Connectivity & ARGB Customization
Storage flexibility is provided by two M.2 slots. The primary M.2_1 slot supports fast PCIe 4.0 x4 speeds when used with Ryzen 5000/3000 series CPUs (PCIe 3.0 x4 with G-Series APUs), while the secondary M.2_2 slot runs at PCIe 3.0 x4 speeds via the chipset. Both slots also support SATA M.2 SSDs. Additionally, four SATA 6Gb/s ports are available for traditional drives, supporting RAID 0, 1, and 10 configurations.
Connectivity includes Realtek 1Gb Ethernet, rear USB 3.2 Gen 1 Type-A ports, and internal headers for front panel USB 3.2 Gen 1 Type-C® and Type-A ports. ASUS Q-Design features like Q-DIMM and Q-Slot simplify memory and expansion card installation, while Q-LED Core provides basic diagnostic feedback. Moreover, personalize your build using the three Addressable Gen 2 headers, controlling connected ARGB strips and devices through ASUS Aura Sync software for synchronized lighting effects.
