550W ATX Power Supply for Modern Standby Systems

This 550W ATX unit delivers 80 PLUS Gold certified efficiency and supports Modern Standby for rapid wake times and improved low-load performance. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation.

Ideal for Quiet Builds Using Sleep States

Suits builders who prioritise low noise and efficient sleep-state transitions in a standard ATX form factor. Not for systems requiring higher continuous wattage than 550W or configurations needing specialised server-grade redundancy features absent from this consumer unit.

Verify ATX Fit and Connector Requirements

Confirm your chassis accepts a standard ATX power supply and that the included cables match your motherboard, CPU and graphics card connectors. Ensure the total system power draw stays within the 550W rating before ordering.

Questions about this item

What motherboard power connectors must my board provide for this 550W ATX unit?

Your motherboard needs a 24-pin ATX connector and an 8-pin (4+4) EPS connector to power the CPU and mainboard rails.

Will this PSU work with an older system that lacks Modern Standby support?

Yes, it operates as a standard ATX supply; Modern Standby features simply remain inactive on legacy platforms.

How can I confirm the Zero RPM fan mode is active after installation?

Under light load the fan should stay completely still; you can verify visually or by listening for silence at idle.
