Description

Description

The Asus Prime B550M-K ARGB motherboard is designed to support AMD Ryzen processors on the AM4 socket. It is aimed at users who wish to build a computer based on the AMD Ryzen platform with a small form factor, as it is a Micro ATX motherboard. Therefore, it is intended for users who need a small-sized motherboard to create a compact computer or a computer for gaming or general use with AMD Ryzen processors.

Prime Series

The ASUS PRIME series is expertly designed to unleash the full potential of the AMD Ryzen Series 5000/ 5000 G-Series/ 4000 G-Series/ 3000 Series platform. Featuring a robust power design, comprehensive cooling solutions, and intelligent tuning options, the PRIME B550 series motherboards provide everyday users and DIY PC builders with a range of performance tuning options through intuitive software and firmware features.

Cooling Design

The PRIME B550 series features comprehensive cooling controls that can be configured via the Fan Xpert 2+ software or through the UEFI BIOS.

  • Each header can dynamically reference three thermal sensors. Fan Xpert 2+ allows you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU and CPU intensive tasks.
  • A dedicated integrated circuit protects each fan header from overheating and overcurrent.
  • Each onboard header supports automatic detection of PWM or DC fans.

PCIe 4.0 Slot

The PRIME B550M-K ARGB offers PCIe 4.0 slot connectivity for GPUs. The wide bandwidth and ultra-fast transfer speeds allow you to create feature-rich builds that can effortlessly handle high loads.

Front USB Type-C

A full array of USB ports supports high-spec equipment loaded with peripherals, including a front-panel USB 3.2 Gen 1 Type-C® port that provides data transfer speeds of up to 5Gbps.

Armoury Crate

Through a single intuitive interface, Armoury Crate offers easily customized Aura Sync RGB settings for every compatible device in your arsenal, as well as controls for an ever-growing family of ASUS products, including keyboard and mouse preferences. 

Armoury Crate also integrates product registration and a news feed, so you never miss updates that interest the ASUS community.

SafeSlot Core

SafeSlot Core is ASUS's exclusive PCIe slot. Featuring a reinforced design that anchors to the motherboard with a special hook, SafeSlot Core provides 1.6X stronger retention and 1.3X greater shearing resistance than standard expansion slots.

Rear panel:

  • 4 x USB 3.2 Gen 1 (5G) ports (4 x Type-A)
  • 2 x USB 2.0 ports (2 x Type-A)
  • 1 x DisplayPort
  • 1 x HDMI™ port

    I bought it for €80, the quality of the PCB construction is excellent, very user-friendly BIOS (includes AI tweaker). It is a good B550 motherboard that provides you with PCIe 4.0 speeds but it is not worth more than €90-100 as there are better options available.
