DELL RSR1A Booster Card Expansion Card for Precision 3930R

Purpose and Compatibility

This Dell RSR1A booster card is an OEM PCIe expansion card built exclusively for the Precision 3930R rackmount workstation. It adds power delivery and expansion capacity so the system can support high-performance components such as upgraded graphics cards. The card fits only the 3930R chassis and is not compatible with any other Dell workstation or standard desktop platform. Buyers who need a universal PCIe riser or a card for a tower workstation cannot use this part.

Sustained Load Behaviour

The card operates on the PCI Express 3.0 standard to provide stable power delivery during extended heavy workloads. It is engineered to maintain consistent current supply to installed GPUs or additional add-in cards without throttling when the system runs at full capacity for long periods. The design focuses on reliable power distribution rather than signal processing, so performance scales with the components you install. No external or internal I/O ports are present on the bracket.

Thermals, Noise and Power

As a passive PCB assembly with no onboard fan, the booster card adds no audible noise to the rackmount chassis. It draws its operating power directly from the PCIe slot and the workstation's power subsystem, so total system draw rises only by the amount required by the attached high-performance cards. The compact 8 × 6 × 1 inch form factor fits the 3930R airflow path without obstructing existing cooling zones. No separate power connectors or external cabling are required.
