250W ATX Power Supply for Modern Standby Systems

This 250W ATX unit delivers 80 PLUS Gold efficiency for lower power draw and reduced heat. Resonant LLC topology with DC-to-DC conversion provides clean power and enables deeper sleep states. It targets builders assembling compact or office PCs that prioritise quiet operation and fast wake times.

Upgrading from Older Low-Wattage ATX Units

The 80 PLUS Gold rating and Modern Standby support replace older bronze or unrated 250W models that lack fast wake-from-sleep capability. Zero RPM fan mode eliminates noise at low and medium loads where legacy units run constantly. The jump is worth it when building a new system that uses modern low-power sleep states and demands silent idle performance.

Suits Compact Builds Needing Gold Efficiency

This supply fits users who need an ATX form-factor unit with Gold-certified efficiency and a fan that stops completely under light loads. Builders requiring higher wattage for discrete graphics cards or multi-drive arrays should look elsewhere. Systems needing modular cabling or specific EPS connector counts not listed here will need a different unit.

Questions about this item

Does the ATX form factor fit a standard ATX case cut-out?

Yes, the unit follows the ATX form factor so it mounts in any standard ATX case cut-out with the usual four screws.

Which cables must be connected first to enable Modern Standby?

Plug the 24-pin ATX and the 4+4-pin CPU cables before switching on the PSU; missing either prevents the fast wake-from-sleep feature from working.

When should the 80 PLUS Gold fan be cleaned to keep Zero RPM mode effective?

Vacuum the intake grille every 6 months; dust buildup raises internal temperature and stops the fan from staying at 0 RPM at low load.
