For Dell Precision 7680, use WD19DC or WD19DCS with both captive USB-C plugs in the two left Thunderbolt 4 ports. It is the only dock family Dell marks supported in the current exact row. Every current WD25 family and every other listed previous family is marked No. Dell documents a single-cable WD22/WD19 workaround with the original barrel adapter, but calls that arrangement unsupported, so it is not an equivalent recommendation. The computer ships with a 180 W or 240 W barrel adapter; WD19DC/DCS provides up to 210 W to a supported Dell host. That fits the documented supported pairing but does not prove full 240 W-equivalent performance under sustained load, so keep the original 240 W adapter available for comparison on that configuration.
This is the only dock family with a positive cell in Dell's live June 2026 exact Precision 7680 row.
Check first: Power it with its 240 W-or-greater Dell adapter and seat both captive host connectors in the two left Thunderbolt 4 ports. Do not use the right non-Thunderbolt USB-C port for the dock.
Dell marks WD25, WD25Z/SD25, WD25TB4/SD25TB4 and WD25TB5/SD25TB5 No in the current exact row.
Check first: Do not rely on a stale 2025 matrix or the presence of Thunderbolt ports. The June 2026 live guide supersedes those older positive-looking rows.
Dell marks WD22TB4, WD19/S and WD19TB/TBS No, while a separate power article describes a limited single-cable workaround with the original host charger.
Check first: Treat the workaround as reuse-only and unsupported. UD22 and HD22Q are also exact negatives. Choose WD19DC/DCS for the supported path.
Still unknown: Dell's documents leave the 240 W sustained-load equivalence and one ExpressCharge battery/adapter note internally inconsistent. The exact Service Tag configuration, GPU and BIOS graphics mode, internal-panel state, monitor EDIDs, DSC/HDR use, cables, mixed refresh rates, current BIOS and dock firmware, Linux parity, thermal/performance behavior and field reliability remain unknown. The March 2023 display table and June 2026 compatibility row are manufacturer evidence, not our hardware test.

Applies only to Dell Precision 7680 regulatory model P114F / type P114F002. It does not transfer to Precision 7670, 7780 or another workstation row. Sources reviewed 21 September 2026. Manufacturer documentation is not a Connect Your Dock hardware test.
“Supported” is Dell’s model-level entry. The screen resolution, cabling and delivered charging power still need to match your desk. Grouped dock variants share the stated matrix column.
| Dock configuration | Manufacturer status | Charging ceiling | Conditions and source |
|---|---|---|---|
| Dell Pro Dock WD25 | Not supported | Up to 100 W on supported Dell systems | Configurations needing more than 100 W may need their own charger with WD25. Select a listed higher-power dock if one-cable power is essential. Dell matrix, page 5 |
| Dell Pro Dock WD25Z / Smart Dock SD25 | Not supported | Up to 130 W on supported Dell systems | Some workstation configurations need more than 130 W. Keep the laptop’s supported charger connected; the dock alone may not sustain full performance. Dell matrix, page 5 |
| Dell WD25TB4 / SD25TB4 | Not supported | Up to 130 W on supported Dell systems | Some workstation configurations need more than 130 W. Keep the laptop’s supported charger connected; the dock alone may not sustain full performance. Dell matrix, page 5 |
| Dell WD25TB5 / SD25TB5 | Not supported | Up to 300 W; host must support the required power range | This Precision model does not support the dock’s extended power range and draws at most 130 W here. A separate laptop charger is required for optimal operation. Dell matrix, page 5 |
| Dell WD22TB4 | Not supported | Up to 130 W on supported Dell systems | Dell marks this exact single-cable dock family unsupported for Precision 7680. The workstation has 180 W or 240 W configurations; use the supported dual-cable WD19DC/WD19DCS route. Dell matrix, page 14 |
| Dell WD19 / WD19S (130 W adapter) | Not supported | Up to 90 W; 130 W is the adapter rating | This configuration may exceed the dock’s charging capacity. Check the laptop’s required power and keep its supported charger available. Dell matrix, page 14 |
| Dell WD19 / WD19S (180 W adapter) | Not supported | Up to 130 W; 180 W is the adapter rating | Dell marks this exact single-cable dock family unsupported for Precision 7680. The workstation has 180 W or 240 W configurations; use the supported dual-cable WD19DC/WD19DCS route. Dell matrix, page 14 |
| Dell WD19TB / WD19TBS | Not supported | Up to 130 W on supported Dell systems | Dell marks this exact single-cable dock family unsupported for Precision 7680. The workstation has 180 W or 240 W configurations; use the supported dual-cable WD19DC/WD19DCS route. Dell matrix, page 14 |
| Dell WD19DC / WD19DCS | Supported | Up to 210 W with a supported dual-cable host | Confirm monitor modes and the device’s power requirement. Dell matrix, page 14 |
| Dell Universal Dock UD22 | Not supported | Up to 96 W; check the laptop requirement | This configuration may exceed the dock’s charging capacity. Check the laptop’s required power and keep its supported charger available. Dell matrix, page 14 |
| Dell Dual Charge Dock HD22Q | Not supported | Up to 90 W to the host | This configuration may exceed the dock’s charging capacity. Check the laptop’s required power and keep its supported charger available. Dell matrix, page 14 |
The exact row was refreshed against Dell’s English 26 June 2026 official matrix. A negative mark remains negative even when its footnote describes a power limitation.
