KHACHIMO Power Supply For SGI/RACKABLE 252W/456W AHW5DC252W AHF5DC456W

SGI/RACKABLE Replacement Power Supply

This new ATX power supply is built as a direct replacement for SGI and RACKABLE systems using the AHW5DC252W and AHF5DC456W part numbers. It delivers up to 456 watts of continuous power with 80 PLUS Gold efficiency. The unit is designed for workstation and server environments that require reliable, standards-compliant power delivery.

Upgrade From Lower Efficiency or Failed Units

The 80 PLUS Gold certification replaces older Bronze or unrated supplies to reduce waste heat and lower operating costs. Modern Standby compatibility upgrades legacy sleep states for faster wake times and better low-load efficiency. Zero RPM fan mode removes audible noise at light loads where older units would spin constantly. Resonant LLC topology with DC-to-DC conversion replaces group-regulated designs to provide tighter voltage regulation and reduce coil whine.

Verify SGI/RACKABLE Compatibility Before Ordering

Confirm that your chassis accepts a standard ATX form factor and that the original unit matches the AHW5DC252W or AHF5DC456W model numbers. Check that the native connector layout matches your backplane and motherboard requirements without adapters. Ensure the 252W to 456W output range covers the peak draw of your installed processors, memory, and storage configuration.
