PowerEdge / GPU enablement

Dell PowerEdge T640 GPU Upgrade Kit

Plan a model-specific GPU enablement requirement across power, cooling, airflow and retention. The editable starting quantities are a parts-planning example, not a universal Dell kit BOM. GPUs, PSUs and missing configuration-specific parts are quoted separately.

Start with your exact system configuration

  • GPU is supported in rack configuration; validate exact chassis and GPU-ready order configuration.
  • Dell technical guide requires two processors and identical GPU models; GPU-ready chassis is selected at initial purchase.
  • Minimum PSU rating is 1100 W; actual power/redundancy needs depend on the full system.
  • Main shroud plus GPU shrouds; standard fans 1/2, high-performance middle fans 3–6, external left/right fans 7/8 form the eight-fan GPU-enabled layout.
  • GPU slots 1/3 require right external fan; slots 6/8 require both external fans. GPU-ready SKU includes both; no left-only SKU is offered.
  • No 18 × 3.5-inch chassis or Fresh Air GPU configuration. 300W GPU configurations have 30°C maximum ambient, with other restrictions depending on CPU/GPU population.
  • Four single-width GPUs conflict with second PERC plus battery H730/H730P/H830; slots 1/3 GPU use restricts 5.25-inch removable media population to one.
  • Technical guide describes up to four double-width 300W or eight single-width 150W GPUs; these are qualified-platform maxima, not approval of arbitrary modern GPUs.
  • Check the CPU thermal rating, exact GPU model and storage-controller combination together. Original GPU-ready ordering conditions are not a guarantee of retrofit support for every installed system.

Part numbers below identify individual components. A shared part number does not make T630 and T640 upgrade packages interchangeable.

  1. Prepare the host

    Record the PowerEdge T640 Service Tag, drive chassis, CPU count, GPU model, PCIe cards and installed cooling. Compare missing parts with the model-specific conditions. Shut down the operating system, disconnect input power and follow ESD precautions. Power-board service can require removal of PSUs and the system board; use the exact service procedure.

    Check: Chassis and GPU qualification, complete retention parts, exact PSU identities and assembly contents reviewed. Power isolated and service sequence understood.

  2. Install the GPU power board

    Seat the GPU interposer at its chassis guides and engage its retention mechanism. Restore removed system components in the service order. The diagram is a functional overview, not a pinout or chassis-location drawing.

    Check: Correct GPU board, secure retention and main power connection verified.

  3. Complete cooling and airflow

    Retain standard fans 1/2, fit high-performance fans 3–6 and the appropriate external fan arrangement. Fit main and paired GPU shrouds; verify both external fans for the full GPU-ready layout.

    Check: No missing fans, obstructed cables or incomplete shrouds.

  4. Fit holders, cards and harnesses

    Match card holders to the chassis and GPU dimensions, then use the permitted PCIe slots. Route exact GPU power harnesses clear of fans. Do not alter pinouts or use connector shape as proof of cable compatibility.

    Check: Card retention, slot allocation, complete cable path and connector fit reviewed.

  5. Restore the airflow

    Seat the correct main and model-specific GPU shrouds, reconnect required fan cables, and restore fillers and covers before applying power. Check that no harness is trapped or obstructs a fan.

    Check: Complete airflow path and closed system; no loose cables or missing panels.

  6. Close, test and record

    Reinstall covers and required airflow pieces. Restore power and inspect hardware detection, fan status, system event logs and GPU diagnostics. Perform workload and thermal checks for the intended configuration.

    Check: No unresolved power, fan, thermal or PCIe errors; final supplied P/N list recorded.

T640 GPU enablement: a complete requirement

Explore the PowerEdge T640 host platform. Review each selected part and any hardware already installed before requesting a complete configuration quote.

Assembly contents and separate options

What does the starting parts list include?

One power board, four adjustable harnesses, two external fan assemblies, four individual high-performance middle fans, one bare cage, two shroud panels and two guide components. Existing standard fans 1/2 and the main shroud must also be correct. A populated cage must not be counted again as separate fans.

Is there one manufacturer P/N for everything?

489-BBCW is a configured-order GPU option; it is not a verified universal service BOM. PET640GPUKit is a supplier SKU. 5106547 is a configurator option identifier. None is an alias for X7C1K or a guarantee of the contents offered here.

Are T630 and T640 kits interchangeable?

No. X7C1K and DRXPD appear in both platforms, but cooling, airflow, mechanical retention and host qualification differ. Use the matching model page.

Which details are still required for a complete quote?

Send Service Tag, CPU count and models, drive-cage layout, GPU model/P/N and quantity, PSU labels and input voltage, existing fan/shroud photos, PCIe controllers, delivery country and required condition. PSU P/Ns are selected from the complete configuration; no unverified PSU number is assigned here.

Fan and shroud alternatives

X4JNY is not a confirmed substitute for 8DF31. Standard RF4VK / 6KK42 assemblies are not established replacements for GPU high-performance cooling. GXH1V and MRY2P service assemblies must be checked for included panels before adding individual pieces.
