Direct replacement for Acer Aspire T671 M5400

This 300W ATX power supply is built as a direct replacement for the Acer Aspire T671 M5400. It fits standard ATX mounting points and uses a single fan in a grey chassis. The unit delivers 300W of steady power for everyday desktop workloads and can serve as a repair part for compatible Dell, HP or other systems that accept this form factor.

Sustained output with protection features

The supply is rated for continuous 300W delivery rather than a short burst figure. It includes output over-voltage protection and is specified for low ripple and noise under load. High-efficiency operation helps keep temperatures stable during extended use, and the single fan manages airflow across the power module without additional cooling requirements.

Connector set for legacy and current drives

Cable complement includes one 20+4-pin ATX connector, one 4-pin ATX12V connector, two peripheral power connectors, one floppy drive connector and three SATA power connectors. This mix supports older IDE devices alongside modern SATA storage in a single build. The grey enclosure and standard ATX dimensions allow straightforward mounting in compatible cases without adapter brackets.
