Technical Specifications
Frequently Asked Questions
Singular Expert Insight
Choose WT78X if you want a clean, IT-friendly Windows 11 Pro tower with current-gen Intel Core Ultra performance and room to add RAM/storage later — without paying for a Core Ultra 7 you do not need. If you specifically need higher CPU headroom for compiles or virtualization, the Core Ultra 7 265 variant of the same QCT1250 chassis is the natural step up. If you are tight on desk space, a Dell Pro Tiny (Mini PC) sibling delivers similar Series 2 CPU options in a much smaller footprint.
Buyer's Guide
Buy it if
You need a modern Windows 11 Pro business tower with TPM 2.0, NVMe SSD and an upgrade-friendly chassis for the next refresh cycle.
Skip it if
You need a discrete GPU out of the box, a true workstation-class CPU, or a tiny / 1L form factor — this is a standard mini-tower business desktop.
Also consider
Dell Pro Tower QCT1250 with Core Ultra 7 265 for heavier multitasking, or a Dell Pro Tiny QCT1250 family unit for the same CPU class in a 1L footprint.
