200W 80 PLUS Gold PSU for compact builds

The KHACHIMO PWS-201-1H is a 200W ATX power supply built to the 80 PLUS Gold efficiency standard. Its 1U form factor targets small-form-factor cases, rackmount chassis and thin-and-light workstations where internal volume is at a premium.

ATX connectors and 1U depth simplify tight installs

Standard ATX output connectors plug directly into mainstream motherboards without adapters. The shallow 1U profile leaves clearance for low-profile coolers or riser cards, while the fixed cable set keeps routing predictable in cramped enclosures.

Zero RPM mode and Gold efficiency cut heat and noise

At low and medium loads the cooling fan stops completely, delivering near-silent operation during everyday tasks. Resonant LLC topology with DC-to-DC conversion supplies clean power, reduces coil whine and supports Modern Standby sleep states for fast wake times and lower idle draw.

Questions about this item

What does the 80 PLUS Gold rating mean for this 200W unit?

It certifies high efficiency at typical loads, reducing power draw, heat output and fan noise compared with lower-rated supplies.

What physical space does this 1U supply need to fit?

The 1U form factor is designed for standard rack-mount or slim chassis with a single rack-unit of vertical clearance.

How is the Zero RPM fan mode enabled, and what mistake stops it working?

The fan stops automatically at low and medium loads; blocking the intake or exhaust vents prevents the thermal control from triggering silent operation.
