ASUS Pro Q870I-C-CSM Intel motherboard

The ASUS Pro Q870I-C-CSM is a Mini ITX desktop motherboard built around the Intel Q870 chipset and LGA-1851 socket. It targets system integrators and small-form-factor builders who need a compact, commercial-grade platform for office or embedded workloads.

Capacity and headroom

The board provides two SATA 6Gb/s ports for traditional storage drives and includes an M.2 Key E slot for wireless add-in modules. Expansion is limited to the single PCIe slot inherent to the Mini ITX form factor, so multi-GPU or multi-card configurations are not supported.

Thermals, noise and power draw

Passive chipset cooling keeps acoustic output at zero decibels under typical loads. Power delivery is scaled for the 870-class platform and draws only what the installed processor and peripherals require, making it suitable for fanless or low-airflow chassis.
