  • 80 PLUS Gold certified for high efficiency and lower power consumption
  • Zero RPM fan mode stops the fan at low loads for near-silent operation

Compatible Dell OptiPlex SFF Systems

This 240W ATX power supply is built as a direct replacement for Dell OptiPlex 390, 790, 990, 3010, 7010 and 9010 small form factor desktops. It matches the original H240AS-00 and L240AS-00 part numbers and supports Modern Standby for rapid wake-from-sleep performance.

Verify Form Factor and Connector Fit

Confirm your chassis is the small form factor version, not the tower or micro-tower, as the physical dimensions and connector layout differ. Check that the existing unit carries part numbers such as 0F79TD, 03WN11, F79TD or 3WN11 to ensure the pin-out and mounting holes align before ordering.

Ideal for Office Refreshes, Not High-Power Builds

The 80 PLUS Gold efficiency, Zero RPM fan mode and LLC resonant topology suit quiet office environments and standard business workloads. Builders adding discrete graphics cards, multiple drives or overclocked CPUs should look elsewhere because the 240W rating and SFF connector set cannot support those power demands.

Questions about this item

What comes with the 240W unit and do I need extra cables for an OptiPlex 390 790 990 3010 7010 9010SFF?

The power supply is a direct replacement for the H240AS-00 L240AS-00 0F79TD 03WN11 F79TD 3WN11 units and uses the existing ATX connectors in those OptiPlex models so no additional cables are required.

How do I choose between the part numbers listed such as H240AS-00 L240AS-00 0F79TD 03WN11 F79TD 3WN11?

All the listed part numbers refer to the same 240W ATX form factor used across the OptiPlex 390 790 990 3010 7010 9010SFF range; pick the one that matches the label on your current unit.

What does the 240W Gold rating mean for daily use in an OptiPlex SFF?

The 80 PLUS Gold certification means higher efficiency at typical loads, so the supply draws less wall power, runs cooler and lets the Zero RPM fan stay off longer during light work.
