## Long description

The Inter-Tech ASPOWER U1A-C20300-D 300 W power supply unit is designed for server and compact system applications. It provides a 20+4 pin ATX connector for compatibility with a wide range of motherboards and comes in a stainless steel housing. The unit supports an AC input voltage range of 115–230 V and incorporates built-in protection against overcurrent, overvoltage and short circuit. With a rated output of 300 W and a mean time between failures (MTBF) of 100,000 hours, the supply is intended to offer continuous operation in constrained rack or small-form-factor environments.
Advantages
The stainless steel casing ensures structural rigidity and aids heat dissipation while remaining compact for limited installation spaces. Integrated protective circuits reduce the risk of damage to connected components during voltage anomalies or fault conditions. A small cooling fan (diameter 4 cm) and the unit's efficient internal layout contribute to stable operation and help maintain the rated output under typical server loads. The 20+4 pin ATX connector allows straightforward connection to standard motherboards used in many server and embedded systems.
Suitable for
 Small servers and rack-mounted systems with limited space
 Embedded systems and industrial PCs requiring ATX-compatible power
 Replacement or upgrade in compact workstation or server chassis
 Applications where continuous operation and protection features are required
Key specifications

How to use
Install the power supply into the designated bay of the server or chassis, ensuring stable mechanical mounting and proper grounding. Connect the 20+4 pin ATX plug to the motherboard main power socket, and attach any additional required peripheral power leads according to the system layout. Verify the input voltage selector or configuration (if present) is set to match the local mains supply within the 115–230 V range. After installation, power on the system and monitor initial operation for normal fan activity and stable voltage at the motherboard power pins.
Usage recommendations
Place the unit in an environment with adequate airflow and ambient temperature within the manufacturer's specified operating range. Avoid obstructing the fan intake and regularly check for dust accumulation. Use in systems where the total connected load does not exceed the rated 300 W and allow for headroom to accommodate peak currents. Do not open the housing; servicing should be performed by qualified personnel to preserve safety and protection features.
