Dell OptiPlex 3020 7020 9020 power supply

This 290 watt unit is a direct replacement for the H290AM-00 and related part numbers used in Dell OptiPlex 3020, 7020 and 9020 mini-tower systems. It also fits the Precision T1700 workstation and Inspiron 3670 desktop. The supply delivers standard motherboard and CPU power through an 8-pin and a 4-pin connector.

Replaces failed or noisy OEM units in listed

Swapping in this supply restores reliable power when the original unit fails, becomes loud or shows voltage instability. The upgrade is worth it when the existing PSU can no longer hold load or when a rebuild requires a fresh, new component with the correct pin-out and form factor.

290 watt capacity handles stock OptiPlex

The output comfortably runs the standard processor, memory, integrated graphics and typical office peripherals for the supported models. Headroom runs out when high-power discrete graphics cards or multiple drive arrays are added beyond the original system specification. Builders needing auxiliary PCIe power connectors or higher continuous current should look elsewhere.

Questions about this item

What are the 150 85 140mm dimensions for the H290AM-00 power supply?

The unit measures 150 mm wide, 85 mm tall and 140 mm deep, matching the standard MT chassis used by the OptiPlex 3020, 7020 and 9020.

Which power cables must be connected during installation of the H290AM-00?

Connect the 8-pin motherboard connector and the 4-pin CPU connector; the step most often missed is seating the 4-pin CPU plug firmly until it clicks.
