Compatible Dell Replacement

This ATX power supply replaces Dell part numbers H057N, H056N, G9MTY and 5V0JP. It is built for owners of compatible Dell desktops who need a direct swap for a failed or ageing unit. The 300W output matches the original specification for supported systems.

Single Fan ATX Fit

The unit uses a standard ATX form factor with one cooling fan and weighs 2.2 units. It requires a case and motherboard that accept ATX power supplies and the Dell-specific pin-outs listed above. Builders needing higher wattage or a different connector layout should look elsewhere.

商品問答

What is the maximum continuous power the 300W ATX unit can deliver under sustained load?

The unit is rated for 300 W continuous output, so sustained loads up to that level are within specification.

How loud does the single fan become when the supply runs all day?

The design uses one fan that spins only as fast as needed to keep internal temperatures in check, keeping acoustic output low during extended operation.
