750W ATX power supply for modern standby systems

This 750W ATX power supply is built for desktop PCs that use Modern Standby sleep states. It delivers enough headroom for mid-range components while meeting 80 PLUS Gold efficiency targets. The unit suits builders who want low idle power draw and fast wake times.

80 PLUS Gold efficiency with zero-RPM fan mode

Gold-rated efficiency keeps consumption, heat and noise lower across the load range. A zero-RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion further reduces coil whine and supports efficient sleep states.

Resonant LLC topology and DC-to-DC conversion

The resonant LLC design with DC-to-DC conversion provides clean, consistent power output and minimises coil whine. Standard ATX dimensions allow installation in typical cases without special mounting. No proprietary connectors are required for mainstream motherboards and graphics cards.

Questions about this item

How do I install this ATX power supply and which step do people often miss?

Mount the unit in the case with the four screws, connect the 24-pin motherboard cable and the CPU power cable, then verify the power switch on the rear is set to on before pressing the case button.

What maintenance or replacement will this 750W unit need later?

The Zero RPM fan mode keeps the fan off at low load, reducing wear; expect to clean dust from the intake grill annually and replace the unit only if fan noise appears or voltages drift.

What limit appears first under sustained heavy load on this Gold-certified supply?

The 80 PLUS Gold rating guarantees efficiency up to full load, so the first limit is typically the 750W output ceiling — exceeding it triggers over-power protection and shutdown.
