240 W server power supply for Dell OptiPlex 390 and 790 small form factor chassis

  • 240W output powers Dell OptiPlex 390 and 790 SFF systems
  • New condition ensures reliable operation from first boot
  • Direct-fit design matches H240ES-00 form factor for small chassis
  • Server-grade supply delivers stable power to compact Dell desktops

Dell OptiPlex 390 and 790 SFF compatibility

This 240 W server power supply is built for the Dell H240ES-00 unit found in OptiPlex 390 and 790 small-form-factor chassis. It delivers the exact connector layout and output rails those workstations expect. The unit is new and intended as a direct replacement for the original Dell part.

Steady 240 W output under continuous load

The supply is rated to provide its full 240 W continuously rather than only in short bursts. Voltage regulation stays within ATX limits during extended operation typical of always-on office or server deployments. Thermal protection engages if internal temperatures exceed safe thresholds. It is not suited for systems that demand higher sustained wattage or redundant power modules.
