1. 400-watt capacity

2. 80 PLUS Bronze certification

3. Single 12V rail design

4. Active PFC (Power Factor Correction)

5. Modular design

1. Efficient: The power supply is 80 PLUS Bronze certified, which means it converts at least 82% of the input power into output power under standard loading conditions. This helps reduce energy waste and lowers electricity bills.

2. Reliable: The single 12V rail design ensures stable voltage delivery to the components, reducing the risk of voltage fluctuations that can cause system instability and component damage.

3. Quiet: The power supply is relatively quiet due to its advanced fan control mechanism that adjusts fan speed based on load, minimizing noise under light loads.

4. Flexible: The modular design allows users to configure the power supply with only the connectors they need, reducing clutter and improving airflow within the case.

1. Limited connectors: The power supply comes with a limited number of connectors, which might not be sufficient for high-end systems with multiple graphics cards or other power-hungry components.

2. No EPS12V connector: The power supply does not include an EPS12V connector, which is required for some motherboards to support overclocking and other advanced features.

3. Limited wattage: With only a 400-watt capacity, this power supply may not be suitable for high-end systems with power-intensive components.

The HP D23-400P1A N97955-001 / 002 power supply is a reliable and efficient option for powering HP Elite Tower 600 and 800 G9 series computers. Its modular design, quiet operation, and 80 PLUS Bronze certification make it an attractive choice for those seeking a balance between cost and performance.
