Dell PowerEdge R300 Replacement PSU

This 400W power supply replaces the D400P-00, H400P-00 and DPS-400YB units used in Dell PowerEdge R300 servers. It is built for administrators who need a tested, working spare to restore power to a failed rack system. The unit matches the original ATX form factor and connector layout for direct installation. It serves IT teams maintaining legacy Dell infrastructure where proprietary pin-outs prevent the use of standard retail units.

ATX Form Factor Limits Upgrade Options

The ATX mechanical standard fixes the physical envelope and connector set, so this supply cannot be adapted to newer Dell servers that require different backplane pin-outs or higher wattage delivery. Its 400W rating restricts use to the original R300 configuration and prevents support for power-hungry add-in cards or processor upgrades beyond the platform design. Builders needing redundant or hot-swap capability must look to chassis-specific redundant modules instead.
