The bottom edge of the Aorus Master has a slew of headers covering audio, lighting, fan control, and more. Below is a list of these headers and jumpers, from left to right. Skipping over the fanless chipset heatsink, the right side of the board is where you’ll find the debug LEDs and SATA Ports. The debug LED consists of four lights, CPU, VGA, DRAM and Boot, which light up during POST. If one of these steps hangs/fails, the LED stays lit, informing you where things went wrong when booting the PC. The six SATA ports are standard fare on B550 (and X570 too), with the Aorus Master supporting RAID 0, 1 and 10. You’ll have full use of all SATA ports regardless of what M.2 modules are connected, since bandwidth is shared through the PCIe lanes.

Moving down to the bottom half of the board, the audio section (far left) is mostly covered by a shroud, outside of a few Nichicon and WIMA FKP2 audio capacitors. Hidden below is the shroud is a Realtek ALC1220-VB codec. A headphone amplifier automatically detects the impedance of the connected device for optimal volume levels. Using a premium codec and components, the audio solution should prove more than adequate for most users.

B550 chipset, X570-like price and features

In the middle of the board are three full-length PCIe slots. The first slot is fed from the CPU, providing 16 PCIe 4.0 lanes through its reinforced slot. The bottom two slots are sourced from the chipset, providing four PCIe 3.0 lanes. The middle slot shares bandwidth with SATA ports 4/5. If there is a device plugged into those SATA ports, slot bandwidth reduces to x2. Multi-GPU users should probably opt for X570. This board does not list support for SLI or Crossfire.
