SKU CH-V8PR-YCR53

An 80 PLUS Gold ATX unit delivering 650W with zero-RPM fan mode and Modern Standby support for quiet, efficient power

  • TypeATX
  • Faster wake-from-sleep with Modern Standby compatibility
  • Lower power draw and cooler running from 80 PLUS Gold certification
  • Near-silent operation at low loads via Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC topology with DC-to-DC conversion
  • 650W ATX output for reliable system performance

650W ATX for Artesyn DC Replacement

This 650W ATX unit is built as a direct replacement for the Artesyn DS650DC-3 server supply. It fits standard ATX bays and delivers the same rated output for workstations or custom server builds that require this specific form-factor alternative.

Sustained load behaviour with Gold efficiency

The 80 PLUS Gold rating means the unit maintains high efficiency across typical continuous workloads, reducing waste heat and keeping internal temperatures lower during long render or compute sessions. Resonant LLC topology with DC-to-DC conversion provides tight voltage regulation under steady demand, while the Zero RPM fan mode stays active through light and medium loads for silent operation.

ATX interface practical limits

As a standard ATX power supply, it connects via the usual 24-pin, CPU and peripheral cables, so cable reach and connector count are defined by the ATX specification rather than proprietary server pin-outs. Builders needing redundant hot-swap modules or the original Artesyn chassis mounting points will find this unit does not match those mechanical or electrical requirements.

Questions about this item

How loud is the fan during all-day use?

The Zero RPM mode keeps the fan stopped at low and medium loads, and the resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter operation.

Which cables or connectors must I already have to install this unit?

It uses standard ATX power connectors, so your motherboard, CPU and graphics card cables from any compatible ATX build will fit directly.

Will it work reliably with older components I plan to keep?

The 650 W output and 80 PLUS Gold efficiency deliver clean, consistent power through the DC-to-DC design, supporting legacy hardware alongside modern sleep states.
