Dell P9550 ATX12V EPS12V Overview
The Dell P9550 is a 280 W internal power supply built to ATX12V and EPS12V specifications. It is designed as a direct replacement unit for compatible Dell OptiPlex and Dimension desktop systems. The unit delivers standardised power rails for motherboards and processors requiring these form factors.
Build Integration and Compatibility
This power supply fits internal bays in Dell OptiPlex GX280, GX320 and GX620 models as well as OptiPlex 330, 740, 745, 755 and Dimension C521 chassis. It provides the necessary ATX12V and EPS12V connectors for the supported motherboards, freeing the builder from sourcing adapter cables or proprietary converters for these specific platforms.
Target Users and Limitations
The 280 W rating suits owners of the listed Dell systems needing a like-for-like replacement or a spare unit for maintenance. Builders assembling custom ATX rigs, upgrading to modern high-wattage components or requiring PCIe power connectors for discrete graphics cards should look elsewhere, as this unit lacks the capacity and connector selection for those scenarios.

Questions sur cet article
How much continuous power can the 280 W Dell P9550 deliver before its protection trips?
The unit is rated for 280 W maximum output; sustained loads at that level will trigger its built-in over-power protection.
What fan noise and heat should I expect when the P9550 runs at full load all day?
Dell does not publish acoustic or thermal figures for the P9550; expect typical ATX12V/EPS12V supply noise under continuous 280 W operation.
Which Dell chassis and motherboard connectors must my system already have for the P9550 to fit and power up?
It requires an ATX12V/EPS12V-compatible Dell OptiPlex chassis such as GX280, GX320 or GX620 with matching main and CPU power headers.
