Dell OptiPlex Micro Plus AI PC Review: Powerful AI Performance Tested

Looking for a compact yet powerful desktop that handles AI tasks without breaking the bank? The Dell OptiPlex Micro Plus Pro Micro AI PC with Intel Ultra 7 255H might be exactly what you need. This next-gen mini PC packs serious processing power into a tiny footprint, making it ideal for creators, remote workers, and small business owners who need reliability without sacrificing performance. I put it through its paces for two weeks to see if it lives up to the hype—and whether it’s a smarter choice than bulkier desktops or pricier workstations. The OptiPlex Micro Plus arrives in a sleek, professional-looking package that’s all business. Measuring just 7.2 x 7.1 x 1.5 inches, it’s one of the smallest full-powered desktops I’ve ever unboxed, yet it doesn’t feel cheap. The all-aluminum chassis has a matte silver finish that resists fingerprints, and the front panel features a subtle Dell logo with a single power button that doubles as a status indicator. Despite its compact size, the build quality is surprisingly robust—no creaks or flexes when I picked it up, and the vented sides suggest Dell prioritized airflow without sacrificing durability. The rear panel hosts four DisplayPort 1.4a outputs, two USB-A 3.2 Gen 2 ports, one USB-C 3.2 Gen 2, a 2.5G Ethernet port, and a Kensington lock slot for security. It’s clear Dell designed this for users who need multiple monitors or peripherals without clutter. Under the hood, the Intel Ultra 7 255H (20 cores, 20 threads, up to 5.3GHz turbo) delivers where it counts. In real-world testing, it breezed through 4K video editing in Premiere Pro, handled 30+ Chrome tabs with ease, and even ran local AI workloads like Stable Diffusion without throttling. The integrated Intel Arc graphics kept up with light gaming at 1080p, though don’t expect AAA titles at high settings. The 32GB DDR5 RAM and 1TB PCIe Gen 4 SSD combo ensures snappy responsiveness, booting up in under 10 seconds and loading large files in a flash. WiFi 6 and Bluetooth 5.3 kept connections stable, and the four DisplayPort outputs let me run a triple-monitor setup with zero lag—something many mini PCs struggle with. Compared to the Mac Mini M2, this Dell offers more raw power and expandability, while the Lenovo ThinkCentre M90q feels less premium despite similar specs. At this price point, the OptiPlex Micro Plus delivers exceptional value for professionals who need a no-nonsense desktop. It’s not the cheapest mini PC out there, but the performance, build quality, and AI-focused hardware justify the cost. If you’re a content creator, developer, or small business owner who values reliability and compactness, this is a fantastic choice. Skip it if you’re a hardcore gamer or need a dedicated GPU—there are better (and cheaper) options for those use cases. For everyone else, this Dell delivers where it matters most: power, efficiency, and versatility in a tiny package.
