Questions about this item

Does the PSU include all cables or are any sold separately?

The unit is non-modular, so every cable is fixed to the housing. It provides four SATA connectors, three IDE connectors, one 20+4 pin ATX connector and one 4+4 pin CPU connector.

How do I decide between the 300 W and 400 W ratings shown for this model?

The label reads Model Number 300W1 but the specifications list a maximum output of 400 W. Treat the 400 W figure as the peak capacity for this unit.

What does the 400 W rating mean once the supply is installed in a server?

It can deliver up to 400 W total across all rails, with 20 A available on the main output. Active PFC and 80 K hours MTBF at 25 °C support continuous operation in 1U chassis.
