Vszerda 300W L300PM-00 power adapter for Dell MT

SKU CH-S08R-ZR1HA

Replaces many Dell part numbers in OptiPlex, Inspiron, Precision and Vostro mini-tower systems with a 300W unit

  • 300 W output powers Dell Mini Tower systems
  • Replaces L300PM-00 and many other Dell model numbers
  • Matches dozens of Dell part numbers for easy swap
  • Brand-new unit ensures reliable operation from day one
  • Designed only for MT chassis, not SFF or USFF

Replacement power adapter for Dell MT

This Vszerda power adapter delivers 300W and replaces the L300PM-00 unit used in Dell Optiplex, Inspiron, Precision, Studio and Vostro Mini Tower systems. It matches a long list of original model and part numbers including PS-6301-05DF and X9GWG. The unit is supplied new and ready for direct swap.

Mini-tower form factor and connector fit

The adapter is built to the Mini Tower chassis standard, so its mounting holes and power connectors align with the original Dell MT layout. Installation follows the original screw positions and cable routing without modification. The supplier notes it does not fit SFF, DT or USFF chassis variants.

300W output decides compatibility

The single specification that determines fit is the 300W rating combined with the Dell MT connector pin-out. Systems that shipped with a lower-wattage or different-form-factor supply will not accept this unit. Buyers needing power for small-form-factor or ultra-small Dell desktops must choose a different adapter.

Questions about this item

What power connector standard does the 300W L300PM-00 use for the motherboard?

It uses the Dell proprietary connector required by OptiPlex and Vostro Mini Tower motherboards, matching the L300PM-00 pinout.

Will this unit fit a Dell OptiPlex 7010 Mini Tower chassis?

Yes, it is built for Dell MT Mini Tower cases such as the OptiPlex 7010 and will not fit SFF, DT or USFF chassis.

How do I install the L300PM-00 and what step is often missed?

Remove the old PSU, slide the new unit into the Mini Tower bay, secure the four mounting screws, then connect the 24-pin main and 4-pin CPU power cables — the CPU cable is frequently forgotten.
