300W ATX Replacement Unit
This 300W ATX power supply replaces Dell L305N-00, L305P-00, L350N-00 and H305P-02 units. It fits standard ATX chassis and delivers 300W of steady power for desktop repairs or basic builds. The grey unit weighs 0.1 and includes a single fan for airflow.
Sustained Load Behaviour
The unit provides high efficiency with low ripple and noise during continuous operation. Output over-voltage protection guards connected components if the load shifts unexpectedly. A single fan manages thermal output across the 300W rating without additional cooling features mentioned.
Installation Notes
The connector set includes one 20+4-pin ATX, one 4-pin ATX12V, two peripheral, one floppy and three SATA power connectors. Builders needing more SATA or modern GPU power cables will find the harness insufficient. Dell proprietary pin-outs on some models may require verification before fitting.

Questions sur cet article
How much noise and heat does the 300W ATX unit produce when running continuously?
It uses a single fan for cooling and weighs only 0.1 kg, so acoustic output and thermal load remain low during all-day operation.
Which existing cables or components must I already have to install this supply?
Your motherboard needs a 20+4-pin ATX socket and a 4-pin ATX12V socket; drives require SATA, peripheral or floppy power plugs matching the unit's connectors.
Will the grey ATX supply work reliably with older Dell L305N-00, L305P-00, L350N-00 or H305P-02 systems?
Yes, it is built as a direct 300W replacement for those exact Dell part numbers and fits standard ATX chassis used in those models.
