Commercial platform Windows 10 N-2 and 5yrs OS supportability
All newly introduced 2020 and later commercial platforms (Latitude, OptiPlex, and Precision) will qualify and ship with the most current factory installed Semi-Annual Channel Windows 10 version (N) and qualify (but not ship) the previous two versions (N-1, N-2). This device platform, OptiPlex 3090 Ultra will RTS with Windows 10 version (20H2, 20H1, 19H2) at the time of launch, and this version will determine the N-2 versions that are initially qualified for this platform.
For future versions of Windows 10, Dell will continue to test the commercial platform with coming Windows 10 releases during device production and for five years post-production, including both fall and spring releases from Microsoft.
Please reference the Dell Windows as a Service (WaaS) website for additional information on N-2 and 5 year Windows OS supportability. Website can be found at this link: https://www.dell.com/support/article/us/en/04/qna44484/dell-windows-as-a-service-waas-supported-products?lang=en.

Powering the system
This system can be powered using a 65 W adapter (4.5 mm input power source) or through the USB Type-C cable connected to a display capable of providing power delivery of 65 W or greater. During normal operation, when the device is connected with a single power source (primary power source), connecting a second power source and disconnecting the primary power source will shut down the device. However, if the secondary power source is disconnected while the primary power source is connected, the system continues to operate normally.
When the device is powered with both the power sources—AC adapter and USB Type-C cable, the AC adapter is the primary power source and USB Type-C is the secondary power source. Disconnecting the AC adapter will shut down the system. If the secondary power source is disconnected, the system continues to operate normally.
| Primary Power Source | Secondary power source connected | Power source disconnected | Operation | ||

| AC Adapter | Rear Type-C | AC Adapter | Shut down | ||
| AC Adapter | Rear Type-C | Rear Type-C | Normal operation | ||
