Replacement PSU for OptiPlex 390 790 990 3010 7010

This 240W server power supply replaces the Dell D240ES-00 unit in OptiPlex 390, 790, 990, 3010, 7010 and 9010 desktops. It accepts a 100-240V input at 50 or 60Hz, making it suitable for global mains voltages. The unit delivers a rated power range of 150W to 250W through a 24Pin main connector and a 4Pin CPU connector.

Steady output within the 150W to 250W range

Under sustained load the supply operates inside its 150W to 250W rating rather than spiking to a short-term peak. The wide 100-240V input tolerance keeps output stable when mains voltage fluctuates. This behaviour suits office workloads that run for long periods without the transient spikes seen in gaming systems.

240mm chassis with standard ATX connectors

The housing measures approximately 240mm or 9.45in in length, matching the original form factor for the listed OptiPlex models. A 24Pin ATX connector and a dedicated 4Pin CPU power plug attach directly to the motherboard without adapters. Builders needing higher wattage or additional peripheral connectors should look elsewhere.

Questions about this item

How loud or hot does the 240 W YINGHUA PSU get when running continuously?

The unit is rated for 150 W to 250 W output with a 100-240 V input at 50-60 Hz; actual noise and heat will depend on the load placed on it inside the OptiPlex chassis.

What must my Dell OptiPlex already have for this 24-pin + 4-pin PSU to fit and power on?

A motherboard with a standard 24-pin ATX connector and a 4-pin CPU power socket, plus a case that can accept a unit approximately 240 mm long.

Will this replacement PSU work alongside the original motherboard and drives in my OptiPlex 790?

Yes — it matches the D240ES-00, AC240ES-00, H240ES-00, AC240AS-01 and H240AS-00 part numbers used in the 390, 790, 990, 3010, 7010 and 9010 models.
