300W ATX replacement unit

This 300W ATX power supply replaces the Sparkle FSP300-60PLN in compatible desktop systems. It provides a direct swap for ageing or failed units in office PCs and basic workstations. The grey enclosure houses a single cooling fan. Builders needing higher wattage or modular cabling should look elsewhere.

Sustained 300W output with protection

The unit delivers a steady 300W stream rather than a short burst rating. High efficiency and low ripple and noise keep voltage stable during extended workloads. Output over-voltage protection guards connected components if the regulation loop drifts. Continuous operation at full load is supported within the design limits.

Fixed cable set with legacy connectors

A 20+4-pin ATX connector and a 4-pin ATX12V connector power the motherboard and CPU. Two peripheral connectors, one floppy connector and three SATA connectors cover drives and older accessories. All cables are fixed, so unused leads remain inside the case. The compact 0.1kg chassis fits standard ATX mounting points.

Questions about this item

How much heat and noise should I expect from the single fan when the 300W unit runs all day?

The single fan cools the 300W unit; with high efficiency and low ripple and noise the unit stays quiet under typical desktop loads.

Which motherboard power connectors must my board already provide for this PSU to work?

Your board needs a 20+4-pin ATX socket and a 4-pin ATX12V socket; the PSU also includes two peripheral, one floppy and three SATA power connectors for drives.

Will the 20+4-pin ATX and 4-pin ATX12V connectors fit an older motherboard that only has a 20-pin and a 4-pin socket?

Yes, the 20+4-pin plug splits to match a 20-pin socket and the 4-pin ATX12V connector fits the older 4-pin header directly.
