Compact and protected
The ASUS prime B350M-A motherboard has been created to bring durability, high speed processing technology and data transfers to small compact computer systems. Built using the 5X Protection III system from ASUS the B350M-A features ASUS SafeSlot Core, ASUS LANGuard, ASUS Overvoltage Protection, Stainless steel i/o back plate and ASUS` DIGI+ VRM for a six phase power design. Premium components also work to optimise and accelerate your system for smooth and seamless operation. Every aspect of the motherboard has been tested thoroughly with twelve separate validation tests for a minimum of 8000 hours to ensure your computer functions correctly in any operating environment.

Cool and quiet operation
The ASUS Prime B350-A has integrated the ASUS Fan Xpert program to ensure your install components remain at optimal temperatures even when under load. The Fan Xpert program takes control of all your installed 4-pin and 3-pin PWM/DC cooling fans that are connected to the ASUS Prime B350M-A and monitors your cooling performance. As temperatures increase the system automatically fine tunes the RPM of your fans for better airflow. You can even customise your cooling profiles to suit your environment, dial back the fans speeds for an extremely quiet system or ramp up the cooling to 100% when your computer is working hard.

Next-Gen data transfers
The B350 chipset featured on this motherboard also brings a host of both internal and external connectivity options to your system. Utilise USB 3.1 for external transfers up to 10Gbps or the ultra-fast M.2 internal connection for a blistering 32Gbps transfer rate

Intelligently controlled
The ASUS B350-M motherboard uses intuitive controls to help you monitor and tweak your system performance. A UEFI BIOS features an easy to navigate user display with the added functionality of ASUS EZFlash for keeping your BIOS up to date. While ASUS S.M.A.R.T (self-monitoring, analysis and reporting technology) helps you to identify issues and monitors your overall performance. ASUS Q-Fan controls further add customisation for your cooling, and you can even save and customise a list of your favourite BIOS tools for easy access. This informative program is great and easy to use, even if you’re a newcomer to PC building or a seasoned pro.

In addition to this system ASUS have provided the AI Suite for your operating system, this all-in-one package gives you the tools needed to keep an eye on any overclocking, monitor your systems power usage, adjust fan speeds and system voltages in one easy to find location.

Thank you for answering my question. However, I have two more questions. Firstly, does this mean I can add one of your Bluetooth and/or wifi dongles? Secondly, I still want to know about the other parts of my question. Lastly will this run Ubuntu? Thanks

Can I link this to Bluetooth and wifi? I want to attach a screen from waveshare and a Bluetooth virtual keyboard. I also want to make a laptop using the Xbox 360 Kinect using adapter. Will the item support this use? P.S I can add all the RAM Sticks.

Asked by: Ro4u
This board only has a built in LAN adaptor. If you want to use WiFi and Bluetooth you would need to add PCI cards supporting both of these connection types or USB.
