KHACHIMO X3850 X3950 X5 1975W Power Supply

1975W ATX power supply for high-density servers

This unit delivers 1975 watts from a standard ATX form factor and is built for KHACHIMO X3850, X3950 and X5 platforms. It targets administrators who need dense, redundant power in rack-mounted systems. The design supports modern standby for rapid wake cycles. Part numbers 7001524-J000, 7001524-J002, 49Y7760, 39Y7203, 69Y5916 and 69Y5917 all reference this model.

Sustained-load behaviour and acoustic profile

80 PLUS Gold certification means high efficiency is maintained across the load curve, reducing waste heat during continuous operation. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight when the supply runs at high output for extended periods. Zero RPM fan mode stops the fan completely at low and medium loads, eliminating acoustic signature until thermal demand requires active cooling.

Replacement scope and upgrade threshold

This supply replaces failed or end-of-life units in the listed X3850, X3950 and X5 chassis without cabling changes. The jump is worthwhile when an existing unit lacks modern standby support or cannot meet the 1975W rating required by newer processor configurations. It does not address builds that need a different form factor or a lower maximum output.
