ASUS TUF B450M-PLUS Gaming AM4 Micro-ATX Motherboard

TUF Gaming motherboards offer easy and safe DIY builds by leveraging great design, innovative engineering, and strong partnerships with major component manufacturers.


  1. Socket AM4 Micro-ATX motherboard with AMD B450 chipset
  2. Supports 1st/2nd Gen AMD Ryzen and A-Series/Athlon CPUs
  3. 4 x DDR4 DIMM sockets (max. 64 GB)
  4. 2x PCIe x16 and 1x PCIe x1
  5. 6x SATA 6Gb/s, 1x M.2, 2x RGB headers
  6. 4x USB 3.1 (one type-c), DVI and HDMI outputs, 3x Audio jacks and LAN

TUF Gaming motherboards are specially designed and tested to survive and thrive in conditions where other boards would struggle. Engineered with highly durable components, these motherboards deliver unwavering stability for any session that last as long as you demand.

When you build with a TUF Gaming motherboard, you also benefit from the TUF Gaming Alliance — an ASUS collaboration with trusted industry partners that ensures easier building, the best compatibility, and complementary aesthetics from components to case.

TUF Protection

SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process, SafeSlot integrates fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.

Electrostatic Discharge Protection

ESD Guards prolong the life of components while preventing damage from electrostatic discharge, providing protection for up to +/- 10kV of air discharge and +/- 6kV of contact discharge — greatly surpassing the respective industry standards of +/- 6kV and +/- 4kKV

Best Surge Protection

TUF LANGuard is a military-grade innovation that integrates advanced signal-coupling technology and premium surface-mounted capacitors to improve throughput, protecting the motherboard from lightning strikes and static electricity.

Flexible Cooling Controls

System temperatures are key to a stable gaming rig ― especially GPU temperatures. TUF Gaming motherboards include Fan Xpert 2+ software that's able to intelligently control system fans based upon the input of multiple sensors, including the temperature of an ASUS graphics card. This ensures that your TUF Gaming system stays perfectly cooled.


With FAN Xpert 2+ you're able to control system fans based on inputs from up to three temperature sources. For example, FAN Xpert 2+ can be set to spin up the chassis fans in response to the GPU temperature. So, when it heats up, additional cooling kicks in — just when you most need it. Choose your temperature sources and thresholds, from motherboard and CPU to GPU, and leave FAN Xpert 2+ to do the rest.

DTS Audio for Gaming Headsets

Hone your battle skills with exclusive DTS Custom onboard audio. Utilising advanced emulation techniques to create positional cues via stereo headphones. DTS Custom takes onboard audio to a new frontier. With three presets ― Aerial, Soundscape, and Tactical ― for different genres, you'll have a distinct advantage in every game.

Outshine the Competition with AURA Sync

A well-tuned system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs as well as strips connected to the onboard RGB headers. And it can all be synced with an ever-growing portfolio of Aura-capable hardware.

Speed Up with Onboard M.2

With x4 PCI Express 3.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. It's the perfect choice for an operating system or application drive, making your PC and apps work as fast as possible.

Native 10Gbps USB 3.1 Gen 2 Type-A Support

With a backward-compatible USB 3.1 Gen 2 Type-A, you'll experience ultimate connection flexibility and blazing data-transfer speeds of up to 10Gbps – or twice as fast as USB 3.1 Gen 1.
