What Is the Dell R740 GPU Power Extension Card?

The Dell R740/R740XD GPU power extension card (part 0MDDTD) is a PCI power riser that provides auxiliary power to GPUs installed in Dell PowerEdge R740 and R740XD servers. It supports NVIDIA K80 and M40 GPU configurations by delivering the additional 12V power that the PCIe slot alone cannot supply — essential for server GPU acceleration in AI inference, VDI, and compute workloads.

In short: A Dell OEM GPU power riser card for PowerEdge R740/R740XD servers — delivers auxiliary power to NVIDIA K80/M40 GPUs beyond what the PCIe slot provides, enabling GPU compute configurations.

Key Features

1. Dell OEM Part 0MDDTD

What it means: Factory-engineered power card for the R740 server platform.
Why it matters: Aftermarket or adapted power solutions risk incorrect voltage, inadequate current, or physical interference.
Result: Safe, reliable GPU power delivery that meets Dell server PDU and thermal specifications.

2. Dual 16-Pin GPU Power Connectors

What it means: 2x16 pin configuration for powering two GPUs or a single high-power GPU with multiple power inputs.
Why it matters: The M40 and K80 GPUs require 150-300W each — far beyond the 75W provided by the PCIe slot.
Result: Full GPU performance without power throttling due to insufficient auxiliary power delivery.

3. R740/R740XD Specific Fit

What it means: Designed for the riser layout and power distribution board of Dell 14th-generation 2U servers.
Why it matters: The R740 has specific riser slot positions and power connector locations — generic cards will not align.
Result: Plug-and-play installation in the designated riser slot without modification.

Key Specifications

Typical Applications

• AI/ML Inference Servers: Powering NVIDIA GPUs in Dell R740 servers deployed for real-time machine learning inference workloads.
• Virtual Desktop Infrastructure: Delivering GPU power for NVIDIA GRID cards in VDI host servers running Citrix or VMware Horizon.
• GPU Render Farms: Supporting multi-GPU configurations in render nodes for 3D animation and visual effects production.
• Scientific Computing: Enabling CUDA-based computation in university and research lab Dell server deployments.

Frequently Asked Questions

"Will this work in a Dell R730 or R750 server?"

This card is specifically designed for the R740/R740XD platform (14th generation). The R730 (13th gen) uses a different riser and power distribution layout. The R750 (15th gen) also uses different riser architecture. Check your server service tag on the Dell support site to confirm the correct GPU enablement kit for your generation.

"Do I need a specific power supply configuration to use GPUs?"

Yes. Dell R740 servers require specific PSU wattage (typically 2000W or 2400W) and a GPU-enabled power distribution board to support GPU configurations. Installing this card alone without the required PSU capacity and PDB will result in the server failing to POST or power-throttling under GPU load.

"Does this card support newer NVIDIA GPUs like A100 or H100?"

The K80 and M40 are Kepler/Maxwell-generation GPUs using specific power connectors. Newer GPUs (V100, A100, H100) may use different power connector types (EPS 8-pin, PCIe 8-pin). Verify power connector compatibility between this card and your specific GPU model before ordering.
