Compatible Dell OptiPlex replacement

This 240W server power supply replaces the original unit in Dell OptiPlex 390 790 990 3010 7010 9010 systems. It delivers 240W maximum power through a 24+4Pin main connector. The unit operates on 100-240V input at 50/60Hz and carries 80 Plus series certification. It ships new as a single non-redundant module.

Builders needing higher wattage or redundant design

This supply suits owners of the listed OptiPlex models who need a direct 240W replacement. It provides +5V at 11A and +3.3V at 3.5A for those platforms. Builders who need more than 240W or a redundant power architecture should look at other options. Systems requiring different connector layouts or form factors are not compatible.

Steady output within rated limits

Under sustained load the unit maintains its rated rails within the 240W envelope. The 80 Plus series rating indicates consistent efficiency across typical operating ranges. Operating humidity spans 20%-90% for stable performance in standard server environments. The 240*72*62mm chassis fits the original mounting points without modification.

Questions about this item

What Dell OptiPlex models accept this 240W PSU with a 24+4Pin main connector?

The unit is listed for OptiPlex 390, 790, 990, 3010, 7010 and 9010 systems that use the same 24+4Pin connector and 240W rating.

Can this single 240W supply replace an older redundant PSU in a Dell OptiPlex tower?

It is a single non-redundant design, so it will only work in chassis built for a single 240W unit; redundant bays require a matching redundant module.

How do I confirm the H240AS-00 is delivering power correctly after installation?

The system should POST and boot normally; the 24+4Pin connector supplies +5V at 11A and +3.3V at 3.5A to the motherboard.
