Replacement PSU for Dell L305P-01 L305-03

This 300W ATX power supply replaces the Dell L305P-01 and L305-03 units. It fits standard ATX cases and uses a single fan for cooling. The grey enclosure weighs 0.1 kg. It targets owners of compatible Dell, HP or other desktops needing a direct swap.

Connector complement decides fit

The unit provides one 20+4-pin ATX connector and one 4-pin ATX12V connector. It also includes two peripheral connectors, one floppy connector and three SATA power connectors. Builders must verify these match the motherboard and drive requirements of the target system.

300W steady output with basic protection

The supply delivers 300W of continuous power with high efficiency and low ripple and noise. Output over-voltage protection guards connected components. It handles typical office or home desktop loads but runs out of headroom for discrete graphics cards or high-core-count CPUs.
