Review LC POWER Atx Supply Used

The LC-Power LC400SI is a high-performance 400-watt ATX power supply unit (PSU) designed for use in desktop computers. This version 2.31 of the LC400SI builds upon the success of its predecessors, delivering reliable and efficient power to your system components.

The PSU is constructed with a 120mm double ball fan, ensuring quiet operation and effective cooling. It features a universal AC input that automatically adjusts to any voltage between 90V and 265V, making it suitable for use in various regions around the world.

The LC400SI offers a total of five modular 12V rails, providing excellent flexibility in cable management and component configuration. Each rail can deliver up to 80A, allowing for the use of high-performance graphics cards and other power-hungry components.

The PSU is 80 PLUS Silver certified, meaning it converts at least 85% of the input power into output power under typical loads, making it more energy-efficient than its non-certified counterparts. It also complies with the ATX12V and EPS12V specifications, ensuring compatibility with a wide range of motherboards and components.

The LC400SI is protected against overcurrent, overvoltage, undervoltage, and short circuits, providing an additional layer of safety for your system. It also features a flat, modular design, making it easy to install and manage in even the most cramped cases.

In summary, the LC-Power LC400SI is a versatile, reliable, and efficient 400-watt ATX power supply unit that is perfect for powering high-performance desktop systems. Its quiet operation, modular design, and compliance with industry standards make it a top choice for builders and enthusiasts alike.

The LC-Power LC400SI is a 400-watt ATX power supply unit (PSU) with 80 Bronze certification. Here are some pros and cons that might help you decide if this PSU is suitable for your needs.

1. Adequate Power: This PSU offers 400 watts of power, which is sufficient for most mid-range systems.

2. 80 Bronze Certification: The PSU meets the minimum efficiency guidelines set by 80 Bronze, ensuring it operates efficiently and reduces energy waste.

3. Modular Design: The LC400SI features a modular design, allowing users to connect only the cables they need, reducing clutter and improving airflow in the case.

4. Protective Features: The PSU offers various protective features, such as over voltage protection, short circuit protection, and over current protection, ensuring your components are safe.

1. Limited Warranty: The LC400SI comes with a limited 3-year warranty, which is relatively shorter than some competitors in the same price range.

2. Noise Level: Some users have reported that the fan can be loud under heavy loads, which could be a concern for those who prioritize silence.

3. Limited Connectivity: This PSU offers fewer connectors compared to some high-end models, which might limit the number of components you can connect.

In conclusion, the LC-Power LC400SI is a decent option for those seeking an affordable, efficient, and modular 400-watt power supply. However, its shorter warranty and limited connectivity options might be a drawback for some users. Ultimately, the decision to buy this PSU depends on your specific requirements and budget. If you need more power or additional connectors, you might want to consider a higher-wattage or more feature-rich PSU. If you're looking for a cost-effective and reliable power supply suitable for a mid-range system, the LC-Power LC400SI could be a good choice.
