Workstation overview

The Dell Precision T3420 is a tower workstation built around an Intel Core i7-7700 quad-core processor running at 3.6 GHz. It ships with 16 GB of DDR4 memory and a 250 GB NVMe M.2 SSD. Windows 10 Pro 64-bit is pre-installed for immediate deployment in professional environments.

Compatibility checklist

Verify that your workflow can operate within the 16 GB memory ceiling, as the four DIMM slots support a maximum of 16 GB with this processor. Confirm that the single 425 W 80PLUS Gold power supply meets the demands of any half-height PCIe x16 or x4 Gen3 expansion card you plan to add. Ensure the 3.5-inch internal bay or the M.2 22x80 mm slot matches your additional storage requirements.

Build integration

The integrated Intel HD Graphics 530 drives up to two monitors via two DisplayPort and one HDMI output, freeing the half-height PCIe x16 slot for a dedicated GPU or accelerator. The internal 3.5-inch bay accepts one 3.5-inch or two 2.5-inch drives, while the M.2 slot accommodates a 22x80 mm NVMe device. A slimline optical bay is also available for legacy media access.
