240W ATX Power Supply for Modern Standby Systems

This 240W ATX power supply is built for desktop PCs that use Modern Standby sleep states. It delivers stable power to compatible motherboards and components while supporting fast wake-from-sleep performance. The unit suits builders who need a compact, efficient PSU for low-power configurations.

80 PLUS Gold Efficiency and Zero RPM Fan Limits

The 80 PLUS Gold certification means the supply meets high efficiency targets at typical loads, reducing waste heat and acoustic output. Zero RPM fan mode stops the cooling fan completely at low and medium loads, so silent operation is only guaranteed within those load ranges. At higher sustained loads the fan will spin and efficiency will follow the certified curve.

Resonant LLC Topology with DC-to-DC Conversion

The resonant LLC topology combined with DC-to-DC conversion provides clean, consistent power and reduces coil whine. This design enables the more energy-efficient sleep states required by Modern Standby. Systems that do not support Modern Standby or that demand higher peak wattage will not benefit from this topology.

Questions about this item

Which model number fits my Dell OptiPlex 3250 or 7040?

The unit is listed as compatible with Dell OptiPlex 3250, 3252, 3267, 3668, 3669, 3040, 3046, 3050, 5040 and 7040; match the model on your chassis label to one of those numbers.

What does the 240 W rating deliver in a typical office desktop?

It supplies up to 240 W total, enough for a standard CPU, integrated graphics, memory and a few drives without exceeding the 80 PLUS Gold efficiency target.

How does the ATX form factor and 6-pin connector limit upgrade options?

The ATX size fits the listed OptiPlex chassis and the 6-pin power connector restricts graphics upgrades to cards that draw power solely from the motherboard slot.
