Replacement PSU for OptiPlex SFF

This 240 W server power supply replaces Dell part numbers F79TD, 3YKG5, JNPVV and PH3C2 in OptiPlex 390, 790, 990, 3010, 7010 and 9010 small-form-factor chassis. It is a new unit built to the original L240AS-00, H240AS-01 and AC240AS-01 specifications for direct drop-in installation.

Universal AC input and fixed output

The unit accepts 100-240 V at 4.0 A across 50-60 Hz mains worldwide without a voltage selector switch. A single 240 W maximum rating covers all rails, so the same brick powers every listed OptiPlex SFF regardless of regional line voltage.

240 W ceiling for legacy SFF builds

The 240 W limit comfortably runs the original processor, chipset, memory and integrated graphics in these chassis. It runs out when a discrete graphics card or multiple mechanical drives are added, so builders planning such upgrades need a higher-capacity design.

Questions about this item

Will the fan or capacitors in this L240AS-00 need replacement after years of daily use?

The unit is a sealed 240W power supply with no user-serviceable parts; long-term reliability depends on the internal fan and capacitors, which are not rated for field replacement.

What limits continuous output before the 240W supply throttles or shuts down?

The 240W maximum rating is the hard ceiling; sustained loads at or near that level will trigger over-current or thermal protection built into the L240AS-00 design.

How much heat and fan noise should I expect when this PSU runs all day in an OptiPlex 7010 SFF?

With a 4.0A draw at 100-240V input, the supply dissipates waste heat inside the small-form-factor chassis; the internal fan will spin continuously under load, producing audible airflow noise typical of compact 240W units.
