This genuine 1000W internal power supply is designed for compatible Z4 G4 and Z6 G4 tower workstations using the factory proprietary power architecture. It provides wide-range AC input, active power-factor correction, multiple dedicated 12V rails, storage-device power, CPU power, and two native 6+2-pin PCIe graphics connectors on the cable revision pictured.
This is not a universal ATX power supply. Confirm the original power-supply part number, workstation generation, connector arrangement, and graphics-cable count before ordering.
Individual rail ratings are not additive. The complete power supply is limited to its stated 1000W maximum combined output.
851383-001, L20514-001, D15-1K0P1A, D1K0E001H
This power supply uses the larger IEC C20 AC inlet and requires an IEC C19 equipment connector. A standard C13 computer power cord is smaller and will not fit.
For standard North American 120V outlets, use the:
9350915 NEMA 5-15P to IEC C19 125V/15A Power Cord
The cable’s 15A/125V rating supports the power supply’s stated 12A maximum input. For 200–240V installations, use an approved regional wall-plug-to-C19 cable rated for the local voltage and current.
Compatibility is limited to the exact G4 tower platforms and configurations listed below. Confirm that the workstation requires the factory 1000W supply and that the original part number and complete cable layout match this listing.
Z4 G4 Tower Workstations
✔️ Z4 G4 with Intel Xeon W-2100 Series: Factory-1000W configurations using supported W-2100-series processors
✔️ Z4 G4 with Intel Xeon W-2200 Series: Factory-1000W configurations using supported W-2200-series processors
✔️ Z4 G4 with Intel Core X-Series: Factory-1000W Core i7 and Core i9 X-series configurations, including supported 7800X/7900X, 9800X/9900X, and 10900X processor families
✔️ Z4 G4 System / CTO References: 1JP11AV and 4HJ20AV system families when configured with the 1000W power supply
✔️ Z4 G4 1000W Configuration References: 3EL60AV, 4HJ44AV, and 3JP05AV configurations or kits when the complete cable arrangement matches
✔️ Z4 G4 Direct Replacement: Systems currently using 851383-001, L20514-001, D15-1K0P1A, or D1K0E001H
⚠️ Z4 G4 465W or 750W Upgrades: Configuration-dependent. Converting a lower-wattage system may require the correct 1000W chassis configuration, front fan, card guide, graphics cabling, and thermal hardware.
Z6 G4 Tower Workstations
✔️ Z6 G4 First-Generation Xeon Scalable: Supported single- and dual-processor Bronze, Silver, Gold, and Platinum configurations using the factory 1000W supply
✔️ Z6 G4 Second-Generation Xeon Scalable: Supported single- and dual-processor Bronze, Silver, Gold, and Platinum configurations using the factory 1000W supply
✔️ Z6 G4 Xeon W-3200: W-3223, W-3225, W-3235, W-3245, W-3265, and W-3275 factory-1000W configurations
✔️ Z6 G4 System / CTO References: 4HJ64AV and 4HJ65AV system families, including applicable regional and configured-to-order derivatives specifying the 1000W supply
✔️ Z6 G4 Direct Replacement: Systems currently using 851383-001, L20514-001, D15-1K0P1A, or D1K0E001H
⚠️ Z6 G4 700W Upgrades: Configuration-dependent. Confirm the system BOM, motherboard connections, graphics requirements, and cooling configuration before converting to 1000W.
❌ Z8 G4: Uses a different high-output power architecture and harness
❌ Z4 G5, Z6 G5, Z6 G5 A, and Z8 G5: Use later-generation power-supply families
❌ Z4 G6i: Uses a newer power architecture and different supply family
❌ Z440, Z640, and Z840: Use different chassis, pinouts, and power-control wiring
❌ ZCentral 4R and Z4 Rack: Use rack-specific power supplies
❌ Standard ATX Desktops: This proprietary supply is not a universal ATX replacement

⚠️ Match the complete part number, connector arrangement, and cable count shown in the listing photos.
⚠️ The R1 connector has a 12-position housing with 10 populated circuits. This is why some catalogs call it a 10-pin connector and others call it a 12-pin connector.
⚠️ This listing is for the harness revision with two native G1/G2 6+2-pin PCIe connectors. A less-common four-graphics-lead revision has been documented under the same spare-number family, so the part number alone does not guarantee four graphics connectors.
⚠️ A 1000W rating does not guarantee support for every graphics card or multi-GPU combination. Verify GPU connector requirements, rail demand, chassis cooling, card spacing, and system firmware support.
⚠️ Do not use the common 465W or 750W G4 power-supply numbers as substitutes. Those supplies have different output capacities and cable configurations.
⚠️ This is a fixed internal supply, not a hot-swap module. Shut down and unplug the workstation before installation.
⚠️ The IEC C20 inlet requires a C19 power-cord connector. A smaller C13 computer cable will not fit.
⚠️ For international or 200–240V operation, use a grounded, locally approved wall-plug-to-C19 cable with the correct voltage and current rating.
