Replacement 300W ATX power module

This Replace Power AP-MPS3ATX30-4 unit is a 300W ATX power supply built to replace Delta DPS-300AB-24B, DPS-300AB-24G and DPS-300KB-1A modules in compatible desktop systems. It delivers steady output for general office or home PC use. The grey enclosure houses a single cooling fan.

Sustained-load behaviour

High efficiency and low ripple and noise ratings indicate stable voltage delivery during continuous operation. Output over-voltage protection guards connected components if the supply drifts beyond safe limits. The single fan manages thermal load for typical desktop duty cycles.

Connector complement decides fit

The unit provides one 20+4-pin ATX connector, one 4-pin ATX12V connector, two peripheral connectors, one floppy drive connector and three SATA power connectors. Builders needing additional SATA or modern GPU power leads must verify compatibility before purchase.

Questions about this item

How loud does the single fan run when the AP-MPS3ATX30-4 delivers 300 W continuously?

The unit uses one fan to move air through the chassis; at full 300 W load the fan spins faster and produces audible airflow, while at lighter loads it runs quieter.

Which motherboard power connectors must my board provide for the AP-MPS3ATX30-4 to work?

The supply includes a 20+4-pin ATX connector and a 4-pin ATX12V connector, so the motherboard needs matching 24-pin and 4-pin sockets.

Can I keep using my older IDE hard drives and floppy drive with the AP-MPS3ATX30-4?

Yes, the unit provides two peripheral connectors for IDE devices and one floppy drive connector alongside three SATA power connectors.
