Micro PS3 400W server power supply

The Athena Power Hercules Series AP-MPS3ATX40P8 delivers 400W of continuous power in a micro PS3 form factor. It is designed for replacement in Dell, HP, IBM, Compaq and Gateway systems or for new micro-ATX and mini-server builds. The unit carries 80PLUS Bronze certification and Active PFC for efficient operation across varied loads.

Compatibility checklist before ordering

Verify that your chassis accepts the micro PS3 dimensions of 3.2 x 1.7 x 6 inches. Confirm the motherboard requires a 20+4 pin main connector, an EPS 8-pin and an additional EPS/P4 connector for CPU power. Ensure your drive configuration matches three SATA, two Molex and one floppy connector, while graphics needs fit two PCIe 6-pin plugs.

Sustained-load behaviour

Active PFC and full-range input from 88 to 264 V maintain stable delivery during extended operation. The 80PLUS Bronze rating guarantees at least 82 percent efficiency at typical loads, reducing heat over long periods. A single fan with smart silent technology manages airflow, while a 17 ms hold-up time bridges brief mains interruptions without shutdown.

Perguntas sobre este artigo

Does the unit include all the cables shown in the connector list or must I buy any separately?

The power supply ships with a 20+4 pin ATX connector, an 8-pin EPS-12V connector, an additional EPS/P4 connector, two PCIe 6-pin connectors, three SATA connectors, two Molex connectors and one floppy connector. No extra cables are required for those interfaces.

Should I choose a single or redundant configuration for a small server build?

This model is a single-unit design rated at 400W; it does not offer a redundant option. For a small server that needs only one supply, the single configuration is the correct choice.

What does the 400W rating mean for actual system load on the +12V rails?

The +12V rails are each rated at 11A, so the combined +12V capacity is the practical limit for modern components such as CPUs and graphics cards. The 400W figure is the total across all voltage rails.
