KHACHIMO Workstation Z4 G4 750W Power Supply DPS-750AB-36A 851382-003

750W ATX Power Supply for Z4 G4 Workstations

This 750 watt ATX unit is built for HP Z4 G4 workstations that require the DPS-750AB-36A form factor. It delivers 80 PLUS Gold certified efficiency for lower running costs and cooler operation. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power for demanding professional components. It suits builders replacing a failed unit or configuring a high-reliability workstation.

Check Physical Fit and Connector Compatibility

Verify that your chassis accepts the specific DPS-750AB-36A housing dimensions and mounting points before ordering. Confirm the cable harness includes every connector your motherboard, CPU and add-in cards require. Ensure the 750 watt capacity matches the total system power draw under full load. Modern Standby support requires a compatible motherboard and operating system to function correctly.

Sustained Load Behaviour and Acoustics

Under continuous load the 80 PLUS Gold rating maintains high efficiency, limiting waste heat and keeping internal temperatures stable. The Zero RPM fan mode remains inactive during sustained output, so the fan runs to manage thermal load. Resonant LLC topology suppresses coil whine even when the unit operates near its rated capacity for extended periods. DC-to-DC conversion maintains tight voltage regulation across all rails during prolonged workstation tasks.
