450W ATX PSU for Modern Standby Builds

This KHACHIMO FSP DS200 unit delivers 450W through an ATX form factor and carries 80 PLUS Gold certification. It targets system integrators and DIY builders who want high efficiency and Modern Standby support for rapid wake-from-sleep behaviour. The resonant LLC topology with DC-to-DC conversion supplies clean power while reducing coil whine.

Suits efficiency-focused desktops.

The Gold-rated platform suits mainstream desktops, home-office workstations and quiet living-room PCs that benefit from low-load efficiency and near-silent operation. Builders planning multi-GPU arrays, heavy overclocking or workstations that regularly exceed 450W should look at higher-capacity units instead.

Zero RPM fan keeps noise down until load climbs

Under sustained load the resonant LLC design maintains stable voltage regulation while the Zero RPM mode keeps the fan stationary at low and medium loads. When demand rises the fan engages progressively, so acoustic output stays low during typical workloads and only increases when the power draw demands active cooling.

Questions about this item

What motherboard power connectors are needed for this 450W ATX supply to work?

It requires a standard 24-pin ATX connector and a 4+4-pin EPS connector from the motherboard.

Will the Zero RPM fan mode still operate quietly when paired with an older graphics card that draws more power at idle?

Yes, the fan stays off at low and medium loads regardless of the GPU, so older cards will not force the fan to spin unnecessarily.

How can I confirm the 80 PLUS Gold efficiency is active after installing the RMG-4514-00?

Monitor system power draw at the wall; the unit should maintain high efficiency across typical loads, running cooler and quieter than lower-rated supplies.
