## Long description

XILENCE XN051 400 W is an ATX power supply unit designed for standard desktop PCs that require stable single-rail power delivery. The unit supplies up to 400 watts total output and provides a 20+4 pin motherboard connector compatible with most mainstream motherboards. It accepts AC input in the 200–240 V range and uses a single 120 mm cooling fan to maintain proper operating temperature. The PSU includes SATA power cables of 400 mm and 550 mm length and a 45 cm motherboard cable, and integrates multiple protection circuits for reliable operation in typical home and office systems.
Advantages
The XILENCE XN051 offers a compact and efficient solution for everyday PC builds, combining a single-rail design with a 16 A limit on the +3.3 V rail to support common peripheral and chipset requirements. Its built-in 120 mm fan balances cooling performance and acoustic behavior while the coordinated connector set simplifies cable routing inside standard ATX cases. Integrated safety circuits provide over-current, over-voltage and short-circuit protection to maintain system stability under varying loads.
Suitable for
 Home and office desktop PCs with standard ATX motherboards
 Budget or entry-level gaming builds with modest power requirements
 System replacements or upgrades where a 20+4 pin connector is required
 Small form-factor cases that accept ATX power supplies with standard cable lengths

How to use
Install the XILENCE XN051 into a compatible ATX power supply bay in your PC chassis and secure it with the supplied mounting screws. Connect the 20+4 pin connector to the motherboard main power socket and attach SATA power connectors to storage devices as needed, using the appropriate 400 mm or 550 mm cable runs. Ensure the AC input is supplied from a 200–240 V mains outlet and switch on the power after verifying all connectors are firmly seated. Allow the internal 120 mm fan to run to maintain cooling during initial operation and normal use.
Usage recommendations
Use this power supply in systems with combined component power draw within the 400 W rating, and avoid connecting high-draw discrete graphics cards or multiple power-hungry devices beyond the unit’s single-rail limits. Maintain adequate case airflow and periodically check cables and connectors for secure attachment to ensure long-term stable operation.
