Purpose and benefit Converts large power supply hole positions to small power supply hole positions, enabling installation of a smaller power supply in a large chassis. Helps you reuse smaller PSUs in existing large chassis without redesigning the enclosure. Provides a clean, reliable mounting solution that preserves chassis rigidity. Material and finish Made from a cool black matte material that is sturdy and resistant to deformation. Black finish helps blend with standard chassis interiors for a professional look. Mounting compatibility and features Fixed chassis is equipped with standard M3 coarsethread holes (eight screw holes) for secure mounting. Includes standard power supply installation holes that support up/down swapping for flexible orientation. Holeposition conversion rack enables easy reconfiguration from largePSU mounting to smallPSU mounting. Installation and use The small power supply panel is installed in the holeposition conversion rack inside the large power supply chassis (black). Designed for straightforward adaptation without altering the chassis structure. Use scenarios Retrofit an existing large PSU chassis to accommodate a smaller, more spaceefficient PSU in data centers or telecom cabinets. Recycle and repurpose older or thirdparty small PSUs in bespoke equipment enclosures that originally housed larger units. Create modular, spacesaving power supply configurations in industrial control panels or lab equipment where space is constrained.
