Utilizing the AMD B550 chipset, this motherboard is designed for use with 3rd and New Generation AMD processors using the AM4 socket. Install up to 128GB of DDR4 RAM across four dual-channel memory slots, supporting speeds up to 5400 MHz when overclocking. Users can also install storage drives using six SATA III connectors with support for RAID 0, 1, and 10. Or install M.2 drives using three M-Key slots. Graphics cards or other adapters are supported via a PCIe 4.0 x16 slot and two PCIe 3.0 x16 slots operating in x4 mode.
The rear I/O panel sports a USB 3.2 Gen 2 Type-C port as well as five Type-A ports. Six USB 2.0 Type-A ports are also present, and a display can be connected using an HDMI 2.1 output. Besides an optical S/PDIF output, the I/O panel also hosts five 3.5mm audio jacks for front speaker, rear speaker, center speaker or woofer, line in, and microphone connections. A Q-Flash Button allows users to flash the BIOS. Alongside an RJ45 port with 2.5 Gigabit Ethernet support, the back panel also incorporates two antenna connectors facilitating Wi-Fi 6 connectivity. Wireless peripherals can also be connected via Bluetooth 5.0.
Internal headers on the B550 AORUS Master include a USB 3.2 Gen 1 and two USB 2.0 headers, supporting two and four Type-A ports respectively. A Thunderbolt header is also present, as are headers for the front panel and front panel audio ports. Users can connect chassis fans using four 4-pin connectors. Two 4-pin connectors can also be used to install radiators, and separate 4-pin connectors can also accommodate a CPU air or liquid cooler. Four RGB headers can also be used to connect lighting components. Audio on the B550 AORUS Master is handled by the Realtek ALC1220-VB Codec, supporting 7.1-channel sound. This motherboard is compatible with Windows 10 64-bit operating systems.

Spent 6hrs troubleshooting this board. All components work in another system. This board will not POST, even after using the BIOS flashback. Starting exchange process with BnH. :/

Splurged for a higher end B550 because it was the only MOBO in stock, and it’s worth it. Lots of USB 3.1 ports, which I use a lot for transferring footage/duplicating external drives. Fast ethernet. Also decent onboard wifi if that’ your thing. Dual m.2 slots so I can use one as a cache drive in Premiere Pro. PCIe slots for Full size graphics card, Raid card, and TB3 card. Not many other boards out there that hit all these marks for me. Build booted up on first try. Only downside is price, but I don’t plan on upgrading for a long time.

I loved this motherboard from the time I opened up the box through installing and set up of my computer.

I had high hopes for this board, but from the minute I installed in my new build there were all kinds of weird problems. Black screens. Poor performance. Other hard hardware refused to work. Also, once I powered down my machine is was difficult to power it back on. Finally after the second day, the board was totally dead. I think this board is just not ready for mainstream release. Too many issues.

Everything runs good so far, haven’t had any issues.
