With a mean time between failures (MTBF) of 100,000 hours, this stainless steel power supply is designed for durability. It includes one 4 cm fan for cooling and has dimensions of 100 mm width, 205 mm depth, and 40 mm height.

## Long description

The Inter-Tech ASPOWER U1A-C20500-D 500 W power supply unit provides reliable DC output for server and small-form-factor systems. With a rated total power of 500 W and an AC input range of 115–230 V, this stainless steel PSU supports stable operation across varying mains voltages. Designed with a non-modular cabling layout and a 20+4 pin ATX motherboard connector, the unit targets installations where fixed cable routing and compact depth are required. The supply achieves an efficiency of 92% and a mean time between failures (MTBF) of 100,000 hours, offering long-term operation with minimal energy loss. The cooling solution uses a single 40 mm fan and the unit measures 100 mm in width, 205 mm in depth and 40 mm in height.
Advantages
High efficiency of 92% reduces heat generation and lowers electricity consumption compared with less efficient designs. The compact depth of 205 mm and slim 40 mm height make the unit suitable for constrained chassis where space is limited. Stainless steel housing improves mechanical durability and aids heat dissipation. A long MTBF (100,000 hours) indicates design reliability appropriate for continuous or near-continuous use. The integrated 20+4 pin ATX connector enables compatibility with a wide range of motherboards without requiring additional adapter cables.
Suitable for
Small servers and micro-ATX systems with limited internal space
Embedded or industrial PCs requiring durable metal enclosures
Systems where a fixed non-modular cable layout is acceptable
Applications needing consistent operation over long duty cycles

How to use
Install the PSU into a compatible chassis designed for compact or shallow-depth power supplies, securing it with the provided mounting points. Connect the 20+4 pin ATX cable to the motherboard main power socket and route fixed cables to the required components, ensuring no sharp bends that could stress the wiring. Verify the AC input voltage matches the local mains (115 or 230 V) and connect the supply to a properly rated AC source with appropriate grounding. Allow for adequate airflow around the 40 mm fan and confirm that system airflow is not obstructed by other components or cabling.
Usage recommendations
For reliable performance, maintain ambient temperature within typical server operating ranges and ensure intake and exhaust paths remain clear. Use this unit in systems where non-modular cabling is acceptable and plan cable routing before final assembly. Periodically inspect the fan and ventilation areas for dust and debris; clean as necessary to preserve cooling efficiency and prolong service life.
