The anti-drop screw design prevents hardware loss during installation, while the bottom-mounted heatsink dissipates heat through the PCB for optimal SSD performance. Three chassis fan headers and PWM/DC support give you precise control over system airflow.
Next-Gen Connectivity & Audio
Stay connected with Wi-Fi 7, offering higher throughput, lower latency, and Multi-link Operation for smoother VR/AR and cloud gaming. The 2.5Gb LAN ensures fast, stable wired connections. Audio is handled by the Realtek ALC4082 codec with Nahimic Audio for immersive 7.1-channel surround sound, noise suppression, and voice stabilization—ideal for streaming and competitive gaming.
Stylish White Design with Polychrome RGB
Finished in a sleek white colour scheme, the Steel Legend features Polychrome RGB headers and compatibility with SignalRGB for synchronized lighting effects. The reinforced PCIe slots and anti-drop I/O shield make installation easier and more secure, while the 8-layer PCB improves signal integrity and energy efficiency.
