PowerRiser M720q/M920q
The PowerRiser is an open-source, custom-engineered replacement riser card for the Lenovo Tiny5 Ultra Small Form Factor (USFF) platform. By exploiting the internal architecture of the host motherboard, it multiplexes connectivity to expose both an open-ended PCIe x8 structural link and an extra integrated M.2 NVMe slot simultaneously, matching the operational logic of stock Lenovo FRUs while expanding overall system capacity.
