Precision T7820 Hard Drive Adapter

This Dell Precision T7820 adapter enables installation of 3.5 inch and 2.5 inch drives into the tower workstation's internal bays. It supports the chassis design that provides four SATA drive bays for storage expansion. The adapter suits IT professionals and workstation builders who need to add or replace hard drives in a T7820 system.

Suits T7820 owners adding SATA storage.

Buyers expanding a Precision T7820 with additional 3.5 inch or 2.5 inch SATA drives will find this adapter matches the chassis drive bays. It is not for users who only need M.2 NVMe installation, as those slots connect directly to the motherboard without a drive bay adapter. Builders working on other Dell tower models or non-Dell workstations should verify compatibility before purchase.

Fits four internal SATA drive bays in T7820 tower

The adapter is designed for the four internal drive bays that accept both 3.5 inch and 2.5 inch SATA storage devices. This bay count and form-factor support are the key specifications that determine whether the adapter matches the workstation's storage expansion layout.

Questions about this item

How much power does the 950W supply draw when the dual Xeon 8160 CPUs and RTX 4000 GPU run sustained workloads all day?

The 950W power supply is rated to deliver up to 950 watts to support the dual Xeon 8160 processors, RTX 4000 graphics, 64GB DDR4 memory, and storage devices under continuous professional workloads.

Which drive interfaces and bay sizes must already be present in the chassis to install the 16TB HDD and 512GB M.2 SSD?

The tower provides four internal bays that accept 3.5 inch and 2.5 inch SATA or SAS drives, plus an M.2 slot for the 512GB SSD; no extra caddies or adapters are required for the listed configuration.

Will the LGA 3647 socket and 12 DIMM slots accept older registered DDR4 modules if I want to expand beyond the installed 64GB?

Yes, the 12 total DIMM slots support registered DDR4 memory up to 768GB, so compatible older DDR4 RDIMMs can be added alongside the existing 64GB to reach higher capacities.
