240W SFF power supply for OptiPlex

This 240 watt power supply is built for Dell OptiPlex small form factor desktops including the 390, 790, 990, 3010, 7010 and 9010 models. It provides a direct replacement for the original L240AS-00, D240ES-00, AC240AS-00 and AC240ES-00 units. The 24 pin and 4 pin connectors match the motherboard layout in these chassis.

Standard ATX connector limits

The unit uses the standard 24 pin main connector and a 4 pin CPU power connector found on the supported OptiPlex motherboards. These connectors deliver up to 240 watts total, which restricts the system to the original low profile components and processors. Builders needing additional PCIe power connectors for discrete graphics cards cannot use this supply.

Replaces failed or aging OEM units

This supply replaces a failed or degraded original power supply in the listed OptiPlex SFF models. The upgrade is worth it when the existing unit no longer holds voltage under load or has developed coil whine. It is not for users moving to a larger case or installing hardware that exceeds the 240 watt rating.
