ATX power supply for modern PCs
This 770W ATX unit is built for desktop systems that demand efficient, reliable power delivery. It suits builders assembling new workstations or upgrading older chassis with a high-efficiency platform. The design supports Modern Standby for rapid wake-from-sleep behaviour. It is not intended for servers requiring redundant or hot-swap power modules.
80 PLUS Gold efficiency rating
The single specification that determines suitability is the 80 PLUS Gold certification, which guarantees high efficiency across typical load ranges. This reduces waste heat, lowers electricity draw and helps keep internal temperatures down. Systems that prioritise quiet, cool operation will benefit directly from this rating. Builds that only need basic bronze-level efficiency may find the extra headroom unnecessary.
Zero RPM fan mode and LLC topology
The bundled cooling behaviour changes acoustics: the fan stops completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion delivers cleaner power and reduces coil whine, further cutting audible noise. Together they enable deeper, more energy-efficient sleep states without fan disturbance. Users who need constant airflow at all loads should note the fan will remain idle until higher demand appears.
