All-in-One thin client for managed desktops

The DELL DMVX7 is an OptiPlex 7420 thin client built around an Intel 300T processor with two cores, four threads, a 3.4GHz clock and a 35W TDP. It ships with 8GB of DDR5 memory and a 256GB M.2 2230 PCIe NVMe Class 35 SSD. The integrated Intel UHD Graphics 710 drives the built-in display while Dell ThinOS provides a locked-down, cloud-managed environment for virtual desktop infrastructure deployments.

Fanless 35W design with 130W external supply

The 35W processor runs without an internal fan, so the chassis is silent during typical office workloads such as browser sessions, video calls and thin-client streaming. A LiteOn E4 130W 7.4mm V3 adapter feeds the system, leaving ample headroom for the display, wireless radio and peripheral ports. Surface temperatures stay low enough for continuous operation in open-plan or hot-desk settings.

Wireless keyboard, mouse and FHD HDR camera included

The box contains a Dell Pro Wireless Keyboard and Mouse KM5221W set, removing the need for separate input-device procurement. An integrated FHD HDR camera supports Windows Hello-style authentication and high-quality video conferencing without an external webcam. Intel Wi-Fi 6E AX211 2x2 802.11ax and Bluetooth provide cable-free network and peripheral connectivity for clean desk deployments.

Questions about this item

How is the 256 GB M.2 2230 PCIe NVMe Class 35 SSD installed, and what step do people often get wrong?

The SSD fits the M.2 2230 slot inside the 2.28-inch deep chassis. Remove the rear cover, insert the drive at a 30-degree angle, then press flat and secure the single screw. People often forget the screw, leaving the drive unseated.

What maintenance or replacement will the 130 W E4 7.4 mm power adapter need later?

The 130 W E4 adapter with 7.4 mm barrel connector is the only field-replaceable power part. Keep the cable strain relief straight; a fractured tip means buying a new LiteOn unit with the same 130 W rating.

What thermal limit appears first on the Intel 300T 35 W CPU during sustained AI workloads?

The 35 W TDP ceiling is reached before the 3.4 GHz turbo can hold. The thin-client cooler throttles the two cores once the 35 W envelope fills, so expect clock drops during long inference runs.
