Description
Complement that AMD build with the Prime B550 Plus AM4 ATX Motherboard from ASUS. Designed for the AM4 socket and using the B550 chipset, this motherboard can support up to 128GB of DDR4 RAM with frequencies up to 3200 MHz or, if overclocking, up to 4800 MHz. Users can also connect up to six SATA III drives and up to two M.2 drives ranging from 2242 to 22110. One of these slots benefits 3rd Gen AMD processors with PCIe 4.0 x4 performance, while the other slot features PCIe 3.0 x4 speeds. The Prime B550 Plus also supports RAID 0, 1, 10, and 5 for more resilient data storage, and CrossFireX allows for multiple-GPU setups. In addition to one M.2 PCIe 4.0 x16 slot and one M.2 PCIe 3.0 x16 slot, users have access to three PCIe 3.0 x1 slots.
In addition to water- and air-cooling components, the B550 Plus’s internal threaders offer support for two USB 3.2 Gen 1 and four USB 2.0 Type-A ports, as well as a Thunderbolt 3 connection and a TPM for BIOS integrity. The back I/O panel also sports single USB 3.2 Gen 2 Type-A and Type-C ports, alongside four Gen 1 Type-A ports. Two USB 2.0 ports also provide connections for a mouse and keyboard, while monitors can be connected via the HDMI or DisplayPort outputs. Five 3.5mm ports are present for audio, alongside an S/PDIF port. Audio is handled by the Realtek ALC887 7.1 Channel Audio codec and takes advantage of shielding and separate layers for the left- and right-side channels, reducing common audio bugaboos such as interference and crosstalk. An ARGB header is present, and the inclusion of ASUS Aura sync allows users to not only match the Prime B550 to their current setup, but also offers central control for compatible RGB components. This motherboard comes with two SATA III cables, as well as a support DVD and a screw package for mounting M.2 SSDs. The ASUS Prime B550 Plus is compatible with the Windows 10 64-bit operating system.

I bought this board along with a Ryzen 5 5600x because when I did a search for a motherboard that works with that CPU this board was listed. I guess I should have done my own research and not trusted B & H since this board is only Gen 3 out of the box and does not have a bios flashback button so there is no way to update bios for a Gen 5 without a Gen 3 CPU. Also why in this day in age do you even have that problem, these boards selling new should already have been updated considering Gen 5 came out October 2020.

so after my 450 started having a lot of booting issues. I decided to upgrade a bit, so far I have no issues, I have notice that the OS and software’s loading time is much faster, all components migrated from the 450 with an addition of a NVM2 1TB as storage OS is on a Sata Nand SSD 500GB, I do missed the orange mb LED’s

No complaints so far! Would’ve liked a heat sink for the SSD. Would like to know if there will be good deals on monitors!
