250 W ATX Power Supply

This 250 W ATX unit is built for compact or low-power desktops that need reliable, efficient power. It suits office PCs, small-form-factor workstations and basic home systems where a modest output is sufficient. The 80 PLUS Gold rating ensures high efficiency across typical loads.

Replaces lower-efficiency or noisy units

Swapping out an older non-Gold supply eliminates excess heat and reduces coil whine thanks to the resonant LLC topology with DC-to-DC conversion. The upgrade is worthwhile when faster wake-from-sleep and silent low-load operation matter, such as Modern Standby environments. Zero RPM fan mode removes fan noise entirely at light loads.

Fits standard ATX bays with modern sleep support

The ATX form factor drops into typical chassis without adapters. Modern Standby compatibility lets the system enter deeper sleep states and resume quickly. High efficiency frees up thermal headroom inside the case, while the fan-stop feature keeps acoustics low during idle or background tasks.

Questions about this item

What case clearance is required for the 250 W ATX power supply?

The unit follows the standard ATX form factor, so any chassis with an ATX PSU bay and rear cutout will accept it.

How do I connect the PSU to an EVA4400 or P6000 system?

Align the unit with the chassis rails, slide it in until the latch clicks, then seat the main power connector firmly into the backplane socket.

Which component should I check if the Zero RPM fan mode stops engaging?

Inspect the internal fan for dust buildup or bearing wear; a seized fan will prevent the zero-RPM feature from activating.
