Dell Dell Pro QCS1250 Slim PC - Intel Core Ultra 5 235 Review
The Dell Pro Slim Desktop has a surprisingly quick CPU for AI tasks, but its 8GB of RAM and tiny 256GB SSD hold it back. We dig into the numbers to see if this trade-off is worth it.
The 30-Second Version
This is a one-trick pony with a good trick. Its Intel Core Ultra 5 CPU is fast (74th percentile), making it great for office and AI tasks. But with only 8GB of RAM and a 256GB SSD, it's immediately cramped. Don't even think about gaming. Buy it only if you desperately need a small, modern business PC.
Overview
The Dell Pro Slim Desktop is a business machine through and through. Its Intel Core Ultra 5 235 processor lands in the 74th percentile for CPU performance, which means it's genuinely quick for office tasks and AI workloads. That's the headline. The rest of the package, however, is built for efficiency, not expansion. You're looking at 8GB of RAM and a 256GB SSD, which sit in the 21st and 18th percentiles respectively. This isn't a machine for hoarding files or running a dozen Chrome tabs while editing a video. It's a compact, reliable workhorse designed to fit under a monitor and just get the job done.
Performance
Performance is a story of two halves. The CPU is the star, with its 14 cores and dedicated NPU handling modern office multitasking and AI-assisted tasks with ease. It's significantly faster than the median desktop in our database for CPU-bound work. The integrated Intel Graphics, however, tell a different story. Sitting in the 37th percentile, they're fine for driving a couple of 4K displays for spreadsheets and presentations, but that's it. Gaming is a non-starter, scoring a dismal 12.5/100 in our tests. The 8GB of DDR5 RAM is fast but scarce, and the 256GB NVMe SSD will fill up quickly with Windows updates and a few large projects. This is a machine where the brain is willing, but the supporting hardware is lean.
Pros & Cons
Pros
- Strong CPU performance: The Intel Core Ultra 5 235 sits in the 74th percentile, making it a capable processor for business applications. 85th
- High reliability score: Rated in the 78th percentile, it's built for the long haul in a business environment. 78th
- Compact form factor: The slim design saves valuable desk real estate. 75th
- Good out-of-the-box connectivity: Includes modern HDMI 2.1 and DisplayPort 1.4a outputs for multi-monitor setups. 66th
- Includes Windows 11 Pro: Adds value for business users needing remote management and BitLocker encryption.
Cons
- Very limited RAM: 8GB is in the 21st percentile, which is tight for modern multitasking. 20th
- Tiny storage: A 256GB SSD lands in the 18th percentile; you'll need external storage almost immediately. 25th
- Weak integrated graphics: GPU performance is in the 37th percentile, ruling out any gaming or GPU-accelerated work.
- Non-upgradable power supply: The 180W PSU locks you into this low-power configuration.
- Heavier than expected: At nearly 6kg, it's not as 'slim' in weight as it is in profile.

Value & Pricing
Priced between $815 and $901, the value proposition is narrow. You're paying a premium for that modern Core Ultra CPU and the Dell business-grade reliability (78th percentile). However, the stingy 8GB RAM and 256GB storage feel out of place at this price point. You can find competitors with similar CPUs that offer double the RAM and storage for less, though they might sacrifice the compact form factor or the Windows Pro license. This is a buy for offices that prioritize a specific vendor, a small footprint, and that AI-ready CPU above all else.
Price History
vs Competition
Compared directly to its intended rivals, it's a specialist. The HP Omen 45L or Dell Alienware Aurora are in a different galaxy for gaming (they'd score near 100/100), but they're also bigger, louder, and more expensive. A more apt comparison might be against other business mini-PCs or even a laptop with a dock. The Lenovo ThinkCentre Tiny series often offers better configurability. The key trade-off here is CPU-for-size: you get a very modern, capable 14-core processor in a very small box, but you accept major compromises on RAM, storage, and graphics to get it.

Common Questions
Q: Is 8GB of RAM enough for Windows 11 and multitasking?
Barely. 8GB places this system in the 21st percentile for RAM, which is on the very low end for modern desktops. It's sufficient for basic office work with a few browser tabs and documents open, but you'll hit limits quickly with more demanding business software or heavy multitasking.
Q: Can this PC run games or video editing software?
No, not really. Its integrated Intel Graphics rank in the 37th percentile, and it scored a 12.5/100 in our gaming assessment. It lacks a dedicated GPU and the power supply to support one. This machine is strictly for productivity and display output.
Q: How future-proof is this configuration?
Not very. The 256GB SSD (18th percentile) will need to be supplemented with external storage soon. The 8GB of RAM is already a constraint. The 180W power supply and integrated graphics mean there's no room to add a GPU later. You're buying this exact performance profile for its lifespan.
Who Should Skip This
Skip this PC if you need to do anything beyond basic office work. Gamers, content creators, engineers, and data analysts should look elsewhere immediately—the 37th percentile GPU and minimal RAM won't cut it. Even general users who like to keep several applications and browser windows open will find the 8GB RAM limiting. If you need more than 256GB of storage on the main drive, this isn't the machine for you. It's built for a very specific, lightweight workflow.
Verdict
We can only recommend the Dell Pro Slim Desktop for a very specific user: a business or home office that needs a modern, AI-capable CPU in the smallest possible footprint and doesn't care about storage space or gaming. The 74th percentile CPU performance is legitimately good, but the 21st percentile RAM and 18th percentile storage are serious handicaps. If your workflow fits neatly within those constraints, it's a reliable, compact machine. For everyone else, the lack of upgrade headroom and poor value make it a tough sell.
