With the Energy Processing Unit (EPU), you’ll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode.

Fan Xpert 4

Flexible Air- and Liquid-Cooling Controls

Fan Xpert 4 software provides comprehensive control over fans, water pumps and all-in-one (AiO) coolers. Whether cooling with air or water, an Auto-Tuning mode intelligently configures all parameters with a single click. There's also an Extreme Quiet mode that reduces all fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans, water pumps and AiO coolers can also be controlled via the UEFI BIOS.

Digi+ VRM Control

Cool to the Core

Prime B550 series is engineered with multiple onboard heatsinks and an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.

Heatsinks

VRM Heatsink and Thermal Pads

A VRM heatsink with underneath thermal pad improves heat transfer from the MOSFETs and chokes for better cooling performance.

Cooler by Design

Prime B550 series features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.

Multiple Temperature Sources

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.

AIO Pump Header

A dedicated PWM/DC header for self-contained water-cooling setups.

Smart Protection

A dedicated integrated circuit protects each fan header from overheating and overcurrent. 

4-Pin PWM/DC Fan

Each onboard chassis fan header supports PWM and DC mode.

Great motherboard, solid and well made and quick with Ryzen 5 5 5600

Gary Rawlins

November 2022

Great board, reasonably priced and all the features you could want

Mr M Jelfs

November 2022

Excellent board for the price and easy to work on.

scott exell

November 2022

No faults and straight forward install

luke plastow

November 2022

Easy to assemble and working exactly as I'd hoped so far

Kieran

August 2022

Working as expected, worked with the new Ryzen 5600 without the need of bios flashback I got this 50 cheaper than I could anywhere else

Ryan O'Neill

June 2022

Excellent board for dev. Only (minor) downside I found is that the BIOS allows you to turn off the silly LED on the motherboard that glows as a stripe but that also then turns off the power / HDD LEDs. The silly glowing motherboard stripe even runs when powered down. I'm not a fan of Joseph's technicolour dreampc so I like to turn all extraneous junk light sources off (also, it's dark where I live, I like it that way). So it ends up pulsing loudly (visually) in the dark room when it is powered off.

Fantastic product, no problems so far
