Overview, specification table and package contents identify 235T, one 16 GB DDR5-5600 module, 256 GB PCI Express NVMe 4.0 SSD, Wi-Fi 6E and 90 W adapter. No Plus model components or optional I/O modules are treated as installed. The regulatory family D19U is confirmed by the original manual, without guessing D19U002 versus D19U003. Omitted. Exact retailers list a three-year service bundle, while the maker family brochure starts at one year and the public Consumer Reports V6TNK description states 12 months. Region and service-entitlement scope were not resolved.3Owner's manualcdn.cs.1worldsync.com/ad/c6/adc6742a-474f-4b13-979f-5e4645168617.pdfRead 7 October 2026Original maker title page identifies QCM1250 and regulatory family D19U.

Exact V6TNK retailers specify Wi-Fi 6E. BE200 is the separate Wi-Fi 7 option and MT7920 is Wi-Fi 6. The matching 235T/16 GB/256 GB lab system in the Principled Technologies report also explicitly uses AX211. Radio antenna module and region-dependent optional external antenna bundle remain unproved and omitted.9Reviewprincipledtechnologies.com/dell/Dell-Pro-Micro-Intel-Core-Ultra-5-235T-OptiPlex-comp-science-0825.pdfRead 5 October 2026Original independent lab report page 4 system table matches QCM1250/235T/16GB/256GB/AX211 and Windows 11 Pro 24H2 build 26100.4061.
