920W ATX Power Supply for Modern Standby Builds

This 920W ATX power supply targets desktop builders who want 80 PLUS Gold efficiency and Modern Standby compatibility in a single unit. The resonant LLC topology with DC-to-DC conversion delivers clean power while reducing coil whine. It suits systems that spend long periods in low-power sleep states and need fast wake times. Buyers who need redundant or server-grade hot-swap units should look elsewhere.

Standard ATX Installation with Zero RPM Fan

Installation follows the standard ATX mounting pattern and uses conventional cable routing for 24-pin, CPU and PCIe connectors. The Zero RPM fan mode keeps the fan completely stopped at low and medium loads, so cable placement near the fan grille does not affect noise. The main risk is forgetting to enable Modern Standby in the motherboard firmware, which leaves the fast wake and low-load efficiency benefits inactive.

Verify ATX Clearance and Modern Standby Support

Check that your case accepts a standard ATX power supply and that the motherboard explicitly supports Modern Standby to use the fast wake feature. Confirm the total system power draw stays within the 920W rating and that your GPU power connectors match the native cables supplied. If the board lacks Modern Standby, the supply still works but the headline sleep-state advantages will not apply.

Questions about this item

How can I confirm the 920W unit is running as intended after installation?

Verify the 80 PLUS Gold efficiency rating is recognised by the system monitoring software and that the fan remains off during low-load Modern Standby wake cycles, indicating Zero RPM mode is active.

What cables are included with the ATX supply and what must be sourced separately?

The power supply includes the fixed ATX main power, CPU and PCIe cables; any additional modular cables or proprietary connectors for specific cases or graphics cards must be obtained separately.

Which efficiency certification should I choose for this 920W model?

This unit carries 80 PLUS Gold certification, delivering high efficiency, lower power draw, reduced noise and cooler operation compared with non-certified alternatives.
