Which docks support Dell Precision 7780?
“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 |
