Overview

An ATX motherboard built on the AMD B550 chipset for Socket AM4 processors. It supports up to 128 GB of DDR4 memory and includes a 2.5 Gbps Killer Ethernet controller.

Power Design and Cooling

The board uses Dr.MOS integrated power stages rated for 50A continuous current per phase. Premium 60A power chokes provide up to three times the saturation current of traditional chokes. An XXL aluminum alloy heatsink covers the MOSFET and chipset areas to maintain stable temperatures.

Storage and Expansion

Three M.2 slots are available: one PCIe 4.0 x4, one PCIe 3.0 x4, and one shared PCIe 3.0 x4 and SATA 6Gbps slot. Six SATA 6Gbps ports provide additional drive connectivity. The primary PCIe x16 slot runs at PCIe 4.0 with a reinforced steel design; two additional x16 mechanical slots operate at PCIe 3.0.

Connectivity and I/O

The rear panel includes a Killer E3100 2.5 Gbps LAN port, HDMI 4K 60Hz output, a Thunderbolt 4 add-in-card header, and dual USB 3.2 Gen2 ports (Type-A and Type-C) at 10 Gbps. Internal headers supply one USB 3.2 Gen2 Type-C front-panel connector, four USB 3.0 ports, and two each of 3-pin 5V and 4-pin 12V RGB headers.

Gaming and Audio Features

Lightning Gaming Ports use dual controller interfaces to reduce mouse and keyboard latency. Nahimic Audio enhances output across headphones, speakers, USB, Wi-Fi, analog, and HDMI with a 360-degree Sound Tracker. Polychrome RGB syncs onboard LEDs and connected strips, fans, and chassis lighting.
