SKU CH-YY87-N95XJ

290 W server power supply compatible with OptiPlex 3020, 7020 and 9020 mini-tower systems

  • Reliable 290W output for OptiPlex 3020 MT
  • Direct fit for OptiPlex 7020 Mini Tower

  • New condition ensures full factory performance

Compatible Dell OptiPlex replacement PSU

This 290 watt server power supply replaces the L290EM-00, D290EM-00 and F290EM-00 units found in OptiPlex 3020, 7020 and 9020 Mini Tower chassis. It is built for system integrators and IT technicians maintaining these specific Dell workstations. The unit delivers the exact factory power rating for direct substitution.

Upgrade from failed or degraded OEM unit

The jump is worth it when the original supply has failed, shows voltage instability or prevents the system from posting. It restores stock power delivery for the supported Mini Tower models. This unit does not fit Small Form Factor or Micro variants and cannot support higher-wattage configurations or aftermarket graphics cards requiring auxiliary power.
