Dell - 950W Power Supply

The Dell 950W Power Supply is a high-efficiency, workstation-grade PSU built specifically for Dell Precision tower workstations including the Precision T5820, T7820, T7920, and T5920. Designed to handle the heavy power demands of multi-GPU rendering rigs, dual-Xeon compute workstations, and AI development machines, this 950W PSU delivers stable, clean power with an 80 Plus Gold efficiency rating that reduces heat output, improves long-term reliability, and lowers electricity costs across years of 24/7 operation.

Unlike generic ATX power supplies, the Dell H950EF-00 950W workstation PSU uses Dell's proprietary connectors, mounting layout, and harness design to drop directly into Precision T5820, T7820, T7920, and T5920 chassis without modification. Whether you are replacing a failed unit, upgrading from a lower-wattage Dell PSU to support more powerful GPUs like the NVIDIA RTX A6000 or Tesla series, or stocking spares for a fleet of CAD, animation, or AI workstations, this 950W power supply is the direct OEM-compatible solution.

This PSU listing covers multiple Dell-issued part numbers that refer to the same 950W workstation power supply: H950EF-00, D950EF-00, AC950EF-00, WGCH4, CXV28, and V7594. All variants are functionally equivalent and interchangeable across Dell Precision tower workstations of the same generation.

Common Dell Part Numbers Covered

This 950W workstation PSU is sold by Dell under several internal part numbers that refer to essentially the same unit. Any of these will work in compatible Precision towers:

• H950EF-00 (most common OEM part number)
• D950EF-00 and AC950EF-00 (alternate revisions)
• WGCH4 (Dell service tag identifier)
• CXV28 and 0CXV28 (Dell service tag identifier)
• V7594 (Dell service tag identifier)

All variants are typically 950W, 80 Plus Gold rated, and built for the Precision tower series.

Compatible Dell Workstations

The Dell 950W power supply is most commonly compatible with the following Dell Precision tower workstations:

• Dell Precision T5820 Tower Workstation
• Dell Precision T7820 Tower Workstation
• Dell Precision T7920 Tower Workstation
• Dell Precision T5920 Workstation (less common but supported)

Always verify your chassis service tag or existing PSU part number before ordering to confirm an exact match.

Ideal For

• Replacing a failed PSU in a Dell Precision T5820, T7820, T7920, or T5920
• Upgrading lower-wattage Precision builds to support high-TDP GPUs (NVIDIA RTX A series, Quadro, Tesla)
• IT departments stocking spare PSUs for workstation fleets
• CAD, 3D rendering, animation, and video editing studios on Dell Precision platforms
• AI and machine learning workstations running multi-GPU configurations
• Engineering, VFX, and architectural visualization teams
• System integrators building or refurbishing Dell Precision towers

Important Things to Keep in Mind Before Ordering

Verify Your Chassis Part Number First Even within the Precision series, there are minor variations between generations and SKUs. Some higher-tier Precision and server models use redundant PSU configurations. Confirm your exact model and existing PSU part number before placing the order.

Confirm Connector Match Dell occasionally updates PSU connector layouts between workstation generations. Make sure your replacement PSU connectors physically match your system's existing PSU harness and motherboard power inputs. This is the single most common source of compatibility issues with workstation PSU swaps.

Why 80 Plus Gold Matters A Gold-rated PSU delivers higher efficiency at typical workstation loads, which translates to less wasted power, lower heat output, quieter operation, and longer overall component life. For workstations running heavy GPU rendering, AI training, or simulation workloads for hours at a stretch, the Gold rating is genuinely worth it.

Not a Standard ATX PSU The Dell 950W power supply uses proprietary Dell connectors and mounting points. It will not fit a generic ATX desktop case and standard ATX PSUs will not fit a Dell Precision tower without case modification. Stay within the Dell ecosystem for a guaranteed fit.
