ATX 750W unit for Modern Standby PCs

This ATX power supply delivers 750 watts and includes a 12-pin connector for modern graphics cards. It targets builders who want efficient, quiet power for systems that use low-power sleep states. The unit suits standard desktop chassis that accept ATX-form-factor supplies. It is not for systems that require higher wattage or redundant power modules.

80 PLUS Gold efficiency rating

The supply carries 80 PLUS Gold certification, meaning it meets high efficiency targets at typical loads. This reduces waste heat, lowers electricity draw and helps keep fan speeds down. Builders who prioritise lower running costs and cooler case temperatures will benefit from this rating. Units without this certification cannot guarantee the same efficiency level.

Zero RPM fan mode and LLC topology

A Zero RPM mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion delivers clean power, cuts coil whine and supports deeper sleep states. Together these features change the acoustic profile and power quality compared with conventional designs. Systems that do not need silent idle or Modern Standby support gain less from these additions.
