SKU CH-6KBW-QNA91

ATX 625 W unit with 80 PLUS Gold efficiency, Zero RPM fan mode, Modern Standby support and resonant LLC plus DC-to-DC topology for clean, quiet power delivery

  • Product typeATX
  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power use and heat
  • Zero RPM fan mode gives silent low-load operation
  • Resonant LLC with DC-to-DC reduces coil whine
  • 625W ATX output for ThinkStation S20 and IdeaCentre models

Lenovo Desktop Compatibility

This 625W ATX power supply is built as a direct replacement for Lenovo ThinkStation S20 30 and IdeaCentre 430, 320 and 330 systems. It matches the original 24-pin connector layout and fits the proprietary chassis mounting points of those workstations and all-in-one PCs. The unit carries 80 PLUS Gold certification for high efficiency at typical loads.

Suited for OEM Upgrades

Ideal for technicians or owners restoring or upgrading the listed Lenovo desktops without adapter cables or case modifications. It supports Modern Standby for rapid wake times. Builders assembling custom ATX systems, users needing modular cables, or anyone requiring higher wattage for discrete graphics cards should look elsewhere.

Fixed Cable Set Included

The supply ships with the fixed cable harness required by the target Lenovo models, including the 24-pin motherboard connector and peripheral leads. No modular cables, GPU power adapters or mounting screws are bundled, so custom builds would need separate cable kits and hardware.
