Replacement for Inspiron 3847

This genuine Dell 300 W power supply is built as a direct replacement for the Inspiron 3847 desktop. It matches the original form factor and connector layout so the system powers up without adapter cables or case modifications.

Capacity and headroom

The unit delivers a maximum of 300 W from a 240 V input, which is sufficient for the factory CPU, integrated graphics and a typical complement of drives. Adding a discrete graphics card or multiple high-draw peripherals will exceed the available headroom.

Proprietary Dell pin-out

The connector pin-out follows Dell’s proprietary layout rather than the standard ATX specification, so the supply only fits compatible Dell chassis. Builders using aftermarket motherboards or cases cannot use this unit without rewiring.

Questions about this item

Will the L300NM-01 300 W unit fit and power my existing Inspiron 3847 or 3000 Series desktop?

Yes, this power supply is built for the Inspiron 3847 and 3000 Series chassis and delivers the 300 W those systems expect.

How can I confirm the PSU is operating correctly once installed?

The system should start without shutdowns, the fan should spin, and the front-panel power LED should stay solid under normal load.

Does the box contain only the PSU or are cables and mounting screws also included?

The unit ships as the bare power supply; any mains lead or case screws must be sourced separately.
