700W ATX Power Supply

This 700W ATX power supply delivers Gold-certified efficiency for desktop PCs that demand stable power and quiet running. Modern Standby compatibility enables rapid wake-from-sleep transitions. Resonant LLC topology with DC-to-DC conversion supplies clean voltage rails and supports deeper sleep states. The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation.

Before You Order

Verify that your case accepts a standard ATX form-factor unit and that the total system power draw stays within the 700W rating. Confirm the motherboard requires a 24-pin ATX connector and check the number of CPU and PCIe leads your components need. Ensure adequate airflow around the PSU intake and exhaust so the semi-passive cooling can function as intended.

Ideal For Quiet Builds

Suits builders who prioritise low-noise operation, efficient sleep states and Gold-level efficiency in a mainstream desktop. Not suited for systems requiring higher wattage output, redundant or server-grade features, or non-ATX form factors such as SFX or TFX. Buyers needing modular cables or specific connector counts not listed here should review the full specification sheet before purchase.
