ATX PSU for Modern Standby Builds

This ATX power supply is built for desktop PCs that use Modern Standby sleep states. It delivers 80 PLUS Gold efficiency and Resonant LLC topology with DC-to-DC conversion for stable, low-ripple power. The zero-RPM fan mode keeps the system near-silent at low and medium loads. It suits builders who want fast wake times and quiet operation.

Standard ATX Mounting and Cabling

The unit fits any case with a standard ATX power-supply bay and uses the usual mounting screw pattern. Connect the 24-pin ATX, CPU and peripheral cables to the matching motherboard and component headers. Ensure the fan opening faces a ventilated panel so the zero-RPM mode can exhaust heat when the fan spins up. No special tools or adapters are required for a typical installation.

Verify Case Clearance and Cable Reach

Check that your chassis provides enough depth for a standard ATX power supply and that the cable lengths reach all connectors in your layout. Confirm the motherboard has a 24-pin ATX socket and the required CPU power headers. Builders needing SFX or TFX form factors, or those with extremely compact cases, should choose a different form factor.

Questions about this item

How can I confirm the power supply is running efficiently after installation?

The 80 PLUS Gold certification means the unit meets strict efficiency targets at typical loads, so lower electricity draw and cooler operation indicate it is working as intended.

What cables and accessories are included with the STD0APIA, and which ones must I purchase separately?

The box contains the ATX power supply unit and standard mounting screws; modular cables for motherboard, graphics cards, drives and peripherals are included, so no extra cables are required for a typical build.

Which capacity version of this ATX power supply should I choose for my system?

Only one ATX model is listed, so select the STD0APIA; its 80 PLUS Gold rating, Zero RPM fan mode and Modern Standby support suit most mid-to-high-performance PCs.
