465W ATX power supply for modern standby PCs

The KHACHIMO 3750-48PS-E delivers 465 watts of continuous power in a standard ATX form factor. It is designed for desktop builds that require Modern Standby compatibility, allowing extremely fast wake-from-sleep times and improved low-load efficiency. This unit suits users who prioritise quiet operation and energy savings in everyday computing.

80 PLUS Gold certification with zero RPM fan mode

The Gold-rated efficiency reduces power draw, heat output and acoustic noise across typical workloads. At low and medium loads the cooling fan stops completely, enabling near-silent operation during office tasks or media playback. Resonant LLC topology with DC-to-DC conversion further lowers coil whine and supports deeper sleep states.

ATX interface limits cable routing

The fixed ATX connector layout determines which motherboards and chassis can be used without adapters. Builders needing non-standard cable lengths or additional PCIe connectors beyond the standard complement must verify fit before purchase. Systems requiring higher sustained wattage than 465W will need a larger capacity unit.

Questions about this item

How long does the 80 PLUS Gold certified fan typically last before it needs replacing?

The Zero RPM mode keeps the fan off at low and medium loads, reducing wear and extending its service life.

Will the 465W limit be reached before the unit overheats during continuous load?

Gold-rated efficiency and LLC resonant topology keep temperatures lower, so thermal protection usually triggers before the 465W ceiling.

How loud is the power supply when it runs all day under typical office loads?

Zero RPM mode stops the fan completely at low and medium loads, giving near-silent operation for most of the day.
