1050W ATX Power Supply for Workstations

This 1050W ATX unit is built for the XW9400 and XW8600 workstation platforms. It delivers high-output power for multi-socket processors, professional graphics cards and large memory configurations. The supply suits builders and IT departments replacing a failed original unit or upgrading capacity in these specific chassis.

80 PLUS Gold Efficiency with Zero RPM Fan Mode

Certified 80 PLUS Gold efficiency reduces waste heat and lowers power draw during typical workloads. A Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean power delivery and helps minimise coil whine.

Modern Standby Support for Faster Wake Times

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency compared to legacy sleep states. The upgrade is worthwhile when the existing supply lacks Modern Standby support or shows instability under heavy professional workloads. It replaces the DPS-1050CB A units identified by part numbers 440860-001 and 442038-001.

Questions about this item

How do I install the KHACHIMO XW9400 XW8600 1050W ATX power supply, and what step do people often get wrong?

Mount the unit in a standard ATX case using four screws, connect the 24-pin ATX, CPU and GPU cables, then verify the motherboard BIOS has Modern Standby enabled so the fast wake-from-sleep feature actually works.

What maintenance or replacement will the KHACHIMO XW9400 XW8600 1050W ATX power supply need later?

The Zero RPM fan stays off at low and medium loads; once the unit runs hot enough to spin the fan, dust the intake grille periodically and listen for bearing noise — that is the only moving part that can wear out.

What limit shows up first under sustained heavy load on the KHACHIMO XW9400 XW8600 1050W ATX power supply?

Continuous draw at the full 1050 W rating will raise internal temperatures until the over-temperature protection triggers, so sustained loads should stay below the peak rating to avoid shutdowns.
