AMD X870 Platform: Built for the Future

Thelio Mira is built around the AMD X870 platform, utilizing an ASRock X870 Pro RS WiFi motherboard paired with System76’s proprietary firmware. This foundation provides support for the latest technologies, including PCIe 5.0 for both graphics cards and storage devices.

One of the most interesting aspects of the Mira’s design is the inclusion of a dedicated Thelio Io daughterboard running open-source firmware. This modular approach to system design not only enhances reliability but also demonstrates System76’s commitment to transparency and user control over their hardware.

Graphics Capabilities: From Gaming to Professional Workloads

Graphics support in the Thelio Mira is handled through a single PCIe 5.0 x16 slot, capable of accommodating the most powerful GPUs on the market. System76 has tested configurations with NVIDIA’s flagship GeForce RTX 5090 and AMD’s Radeon RX 9070 XT, ensuring compatibility with the absolute cutting edge of graphics technology.

The chassis can accommodate GPUs up to 348mm in recommended length, with clearance extending to 358mm for particularly large cards. This generous allowance means even the most extreme custom cooling solutions or oversized reference designs will fit without issue. Power supply requirements scale with GPU choice, ranging from 750W to 1000W depending on the specific configuration.

Memory and Storage: Room to Grow

For memory, the Thelio Mira supports up to 192GB of DDR5 RAM in a dual-channel configuration. This massive capacity makes the system ideal for memory-intensive workloads like virtualization, large dataset analysis, and complex rendering tasks. The system supports various DDR5 speeds depending on the density of the modules installed, allowing users to balance cost and performance according to their needs.

Storage options are equally impressive, with three M.2 NVMe slots supporting different generations (Gen5, Gen4, and Gen3) alongside two 2.5-inch SATA bays. This flexibility allows users to mix and match storage solutions—perhaps using the fastest Gen5 slot for the operating system and applications, while dedicating slower but higher-capacity drives to bulk storage. It’s worth noting that using the second M.2 slot will disable the secondary PCIe expansion slot, so users should plan their configurations accordingly.
