Msi Meg B550 Unify Motherboard

The MSI MEG B550 Unify Motherboard from MSI. The ATX form factor provides immense utility for high-end components for extreme gaming performance. The AMD B550 chipset and AM4 CPU socket provide compatibility with the latest Ryzen brand processors. Install up to 128GB of dual-channel DDR4 memory with speeds up to 5100 MHz for quick multitasking and smooth system performance. Configure a storage array with six SATA III ports and four M.2 PCIe slots for NVMe SSD drives. Further expand the capabilities of the MSI MEG B550 Unify Motherboard with one PCIe 4.0 x16 and one PCIe 3.0 x16 slot for graphics cards, while two PCIe 3.0 x1 slots allow the installation of game capture, audio, and networking cards.You can utilize seven USB 3.2 Gen 1 Type-A and Type-C ports for resource-demanding devices such as external storage or microphones. Another eight USB 2.0 Type-A ports are available for low-resource devices such as keyboards and mice. Wi-Fi 6 (802.11ax) functionality is built into this board for wireless online connectivity, but if you wish to utilize a wired connection, an RJ45 2.5 gigabit Ethernet port also provides a speedy, low-latency online experience. This MSI MEG B550 Unify Motherboard is compatible with the Windows 10 (64-bit) operating system.

Do It Yourself Friendly

Embracing the ever-growing culture of custom PC building, the MEG B550 UNIFY is clearly designed with easily accessible and defined ports. Keep Out Zone ensures case standoffs don't interact with electrical components while installing, keeping your motherboard safe from accidental short circuits. An enlarged PCIe clip helps eject graphics cards without damaging any components. An EZ Debug LED system indicates the sources of possible problems, notifying you if any errors exist within the CPU, DRAM, VGA, or Boot system. You can even switch this function off if you wish with the flick of an on-board switch. A BIOS flashback button allows you to quickly go back to a prior BIOS version, allowing you to continue gaming within moments.

Performance and Protection

MSI designed the MEG B550 UNIFY with a mindfulness, starting with a six layer, 2oz thickened copper printed circuit board which increases conductivity and improves heat dissipation. ESD protection provides additional grounding layers around the mounting holes, preventing potential static discharge from damaging the motherboard. Additionally, the PCIe slots feature steel-armor covering, preventing the weight of heavy graphics cards from affecting the motherboard by heavily reinforcing soldered connections.

Performance Boosting Technology

Lightning Gen 4 works with the M.2 PCIe NVMe SSD slots to provide you with enhanced data transfer speeds up to 64 Gb/s, increasing loading times and general operating system performance. Audio Boost, Nahimic-3, Voice Boost, Isolated Audio Signal, and De-Pop Protection work together to provide studio-grade sound for immersive gaming experiences. Game Boost is a quick one-second enhancement that lets you enable overclocking with just the press of a button. The HDMI output can achieve up to 4K resolution depending on the CPU installed.

Thermal Solutions

MSI provides multiple thermal solutions to keep your motherboard and components cool as you game. Pump fan support allows you to attach various water cooling systems while also reducing radiator noise. Extended heatsinks and cooler pads provide better heat transference through the board, reducing temperature throughout the system. The M.2 Shield Frozr is a specialized heatsink designed for M.2 PCIe NVMe solid-state drives, preventing damage caused by overheating.
