750W ATX Power Supply for Modern Standby Systems

The KHACHIMO RS260-E4/RX8 is a 750W ATX power supply built for PCs that use Modern Standby sleep states. It delivers 80 PLUS Gold certified efficiency to reduce power draw and heat output. The unit suits builders who want reliable energy delivery without paying for higher wattage they will not use. It is not for systems that need more than 750W of continuous power.

Resonant LLC Topology and Zero RPM Fan Mode

Resonant LLC topology with DC-to-DC conversion supplies clean, stable voltage rails and cuts coil whine. A Zero RPM mode stops the fan completely at low and medium loads for near-silent desktop use. The ATX form factor fits standard chassis mounting points. It is not for cases that require SFX or TFX dimensions.

Modern Standby Compatibility and 80 PLUS Gold Rating

Modern Standby support enables extremely fast wake-from-sleep times and better low-load efficiency. The Gold rating means lower electricity consumption and cooler internal temperatures under typical workloads. No extra cables or software utilities are mentioned in the specifications. It is not for users who need modular cabling or per-cable monitoring features.

Questions about this item

Does the 80 PLUS Gold certification cap the efficiency at 80 percent?

No, 80 PLUS Gold means the unit meets higher efficiency targets than the base 80 level, so typical efficiency is above 80 percent at common loads.

What physical space does this ATX power supply need to fit?

It uses the standard ATX form factor, so it mounts in any case with an ATX PSU cutout and the usual four screw holes.

How is the unit installed and what step is often missed?

Secure the PSU with four screws, connect the 24-pin ATX, CPU and GPU cables, then ensure the rear power switch is set to on before pressing the case power button.
