Exclusive Reinforced Features
The MIS MPG B550 Gaming Plus ATX Motherboard is compatible with the third generation of AMD Ryzen CPUs, thanks to its B550 chipset. Utilising exclusive Core Boost Technology, CPU operations are kept smooth even in extreme conditions by a digital PWM, and it runs on an isolated circuit for extra stability. The arrangement of the 10+2+1 pin power connectors helps to keep power flow at maximum efficiency, for consistency.
Enjoy top quality gaming with multi-GPU technology. The MSI MPG B550 Gaming Plus supports AMD’s 2-Way CrossFireX technology. Enjoy the fresh, clean render. The PCIe slots for mounting your GPU are reinforced with steel armour, to protect them from EMI and bending.
Stability and Speed
Stability is a key factor, as it is a continuing theme across this motherboard. Much like the CPU, the DDR4 RAM is another isolated circuit for purer and more stable signals. Operating with Dual Channel technology, the MSI MPG Z490 Gaming Plus has capacity for up to 128GB using the four DIMM slots. Memory settings are fully customisable using the A-XMP software, an easy-to-use interface which make overclocking your RAM simple. Enjoy speeds up to 5100MHz while you game and rest easy knowing it has been thoroughly tested to ensure a stable run.
Providing you with the best support for your components, the MSI MPG B550 Gaming Plus is PCIe 4.0 ready. Boasting double the output of the previous generation, this will deliver fast gaming speeds with the right CPU. Additionally, there are 2 x M.2 and 6 x SATA ports, granting you great flexibility when it comes to storage. One slot is a Turbo M.2 which has ultra-fast access times, helping to reduce load times and keep you in your game.
Overclocking with Ease
To make overclocking your rig easy, the MSI MPG B550 Gaming Plus ATX Motherboard features integrated software and an easy to navigate BIOS. Using Click BIOS 5 software, you have access to a number of systems, either in EZ or Advanced modes, for creating custom settings or one-click presents for all overclocking profiles. To help create stability at extreme speeds, the PCBs come with a layer of 2oz thickened copper, using the copper’s natural conductivity to boost heat dissipation.
Keeping Cool
To prevent your components throttling or bottlenecking, the MSI MPG B550 Gaming Plus has an integrated thermal solution. The M.2 ports come equipped with M.2 Shield Frozr heatsinks which provide the best SSD thermal protection as well as being strengthened for extra stability. What’s more, the heatsink on the digital PWM is extended to enable your CPU to continue running at full speed for extended periods. The motherboard’s thermal pads are capable of transferring heat away from your components at 7W/mK.
Whether a liquid cooling or air cooling enthusiast, the MSI MPG Z490 Gaming Plus ATX Motherboard can support either cooling solution. Fans can be mounted at the top, rear or front, and you can gain easy control over them via the software Fully Fan Control. This simplified interface allows you to set up to four target temperatures across your motherboard and CPU, and can auto-adjust fan speeds and power input between DC and PWM as needed. Additionally, this motherboard can host an AIO system and offers the opportunity for full customisation. The water pump pin header supplies consistent power to your liquid cooling set up.
Mystical RGB
Adding a splash of colour and style to your MSI MPG B550 Gaming Plus ATX Motherboard there is a vivid Mystic Light RGB zone. Customise the RGB lighting using the MSI utilities software, Dragon Center, where there are 29 effects to choose from and a range of 16.8 million colours. Alternatively, create your own – the possibilities are near endless. What’s more, there is a fully customisable front LED which can show in-game and real-time notifications.
Light up your whole rig, too. The MSI MPG Z490 Gaming Plus features JRAINBOW and JRGB pin headers which can be connected to addressable RGB accessories and supply steady power through the extension cables. These too can be controlled from the Dragon Center or turned on and off manually via the EZ LED control switch.
Build and Connectivity
Making building your dream gaming PC is easy with the MSI MPG Z490 Gaming Plus ATX Motherboard thanks to a myriad of features designed to promote safety and stability. The I/O Shield comes pre-mounted with clear stand-off keep out zones, to prevent contact and damage. PCIe ports are equipped with an XL Clip which not only help keep the ports stronger but makes component upgrades much easier for you. Any errors with your system will be lit up across the four integrated EZ Debug LEDs, making for quick identification and hopefully effective resolution.
Connecting to external devices has never been quicker, thanks to the extensive range of USB ports across the I/O Shield. Including a USB-C port, they can transfer data at 10GBps. Additionally, the Realtek 1GB LAN port also provides fast and stable connections, creating a better experience even with the more demanding game titles. The MSI MPG B550 Gaming Plus comes with LAN management software, allowing you to customise traffic priorities and bandwidth on each of your favourite gaming applications. This software can be found in the Dragon Center, alongside all the MSI utility software packages for a more efficient management of your system.
Studio Quality Audio
To complete the gaming experience, the MSI MPG B550 Gaming Plus provides studio quality audio. Another isolated system with its own dedicated processor, the sound is separated into left and right channels then placed onto individual PCBs. This makes for clearer audio and playback is in 7.1 channel high fidelity for a smooth soundscape. The jacks for headset connection are S/PDIF and come with De-Pop technology for a better user experience. Immerse yourself in your gaming world.
