LiteON 1001-X-PWR-AC 400W Power Supply Module: A Comprehensive Analysis

The LiteON 1001-X-PWR-AC 400W power supply module (PS-2421-2-LF) is a reliable option for those seeking a high-performance and efficient power solution for their computing needs. In this analysis, we will discuss the advantages and disadvantages of this power supply unit (PSU), helping you make an informed decision.

1. High Efficiency: The LiteON 1001-X-PWR-AC 400W power supply boasts an impressive 80 PLUS Gold certification, ensuring a minimum of 90% efficiency under typical loads. This translates to energy savings and reduced heat production.

2. Compact Design: With its form factor measuring only 150mm x 86.2mm x 140mm, this power supply is an excellent choice for system builders with limited space within their cases.

3. Active PFC: The Active Power Factor Correction (PFC) feature ensures that the power supply is always delivering the optimal power factor to the electrical grid, improving power quality and reducing energy waste.

4. Overvoltage, Overcurrent, and Short-Circuit Protection: The LiteON 1001-X-PWR-AC 400W power supply comes equipped with various safety features, including overvoltage, overcurrent, and short-circuit protection, ensuring optimal system stability and longevity.

1. Limited Modularity: This power supply comes as a semi-modular design, meaning that only the main 24-pin ATX connector and the 4 4-pin EPS12V connector are hardwired, while the remaining peripheral connectors are detachable. Some users may prefer a fully modular design for easier cable management and flexibility.

2. Noise Levels: Although the LiteON 1001-X-PWR-AC 400W power supply is relatively quiet during typical usage, it may emit audible fan noise under heavy loads. This can be a concern for those who prioritize silence in their computing environment.

3. Limited Warranty: The power supply comes with a limited 3-year warranty, which is slightly shorter than some competitors' offerings. However, LiteON is known for its high-quality components and customer support, making this a less significant concern.
