Velocity Micro's Raptor Z55a (starts at $1,969; $5,609 as tested) lives up to the company's trademark of mighty yet unassuming gaming PCs. Configured here for high-fidelity performance with an AMD Ryzen 7 9800X3D processor and an Nvidia GeForce RTX 5090 graphics card, this rig can pump out some killer frame rates for less cash than similarly configured competitors. What’s more impressive is that the Raptor Z55 achieves those speeds at high detail settings in a sawed-off tower that's a fraction of the size of some giant rigs we've reviewed recently. For pushing frames faster and demanding less money than its competition, the Velocity Micro Raptor Z55a earns our latest Editors' Choice award for cost-no-object gaming desktops.
Configurations: Want the Best Graphics Options? Go With an AMD CPU
The Raptor Z55a’s micro-tower mATX case measures just 12 by 7.6 by 17.5 inches (HWD). While not as compact as the Falcon Northwest FragBox, it’s always exciting to see a beefy gaming PC that can house the massive Nvidia GeForce RTX 5090 GPU and isn’t the size of a diesel engine.
An AMD processor is at the heart of this Raptor Z55 configuration, indicated by the letter "a" in its name. It starts at $1,969 with a Ryzen 5 9600X chip (six cores, 12 threads, at up to 5.4GHz) and an 8GB Nvidia GeForce RTX 5060 card. This price isn't great for the components inside, but the Z55a scales better than any similarly configured system we've tested this year. Our review-unit configuration comes equipped with an AMD Ryzen 7 9800X3D (eight cores, 16 threads, up to 4.7GHz), an RTX 5090 GPU, 64GB of DDR5 (6,000MHz) RAM, and a 2TB SSD for $5,609.
Velocity Micro sells Intel-based Raptor Z55i options that start at $2,119, but these include only up to the Nvidia GeForce RTX 5070 Ti for GPU options. The Z55a goes up to an RTX 5090. Regardless, Velocity Micro serves up plenty of configurations in case you need something special, like upping the storage with numerous SSDs (up to 8TB), adding an optical drive, or installing an SD card reader. If you’re in the market for a high-capacity workstation, you’ve got options here, but note that it’ll cost you.
Design: Plain and Powerful
I mentioned previously that the Raptor Z55a has a low-key design for a premium gaming PC. The mesh panelling on the top and sides provides ample airflow and gives the system an industrial, professional quality. A deeper look inside reveals a spotless build with meticulous cable management. Too bad you won't see it through a side window, some might say!
The design focuses more on performance than visual pizzazz for anyone who isn’t looking for a statement piece for their desk and cares more about raw performance. I also enjoy how quiet the Raptor is when asked to perform under demanding workloads. Compare that with the Corsair Vengeance a5100, reviewed alongside the Z55a, which has a similar configuration but sounds considerably louder under load.
You'll find plenty of rear ports on the Raptor Z55a, thanks to the Gigabyte Aorus Elite B850M motherboard inside this review unit, including four USB 2.0 Type-A ports, five USB 3.2 Gen 1 Type-A connections, two USB 3.2 Gen 2 Type-A ports, and one lonely USB 3.2 Type-C connection. That’s 15 USB ports when you count the two USB Type-A ports and one Type-C on the front panel. The rest of the I/O includes several audio connections, a 2.5Gbps Ethernet jack, a DisplayPort connector for CPU-integrated graphics (not to be used, here), and Wi-Fi radio antenna receivers.
Praise for ports aside, Velocity Micro should include a Wi-Fi 7 radio for what you're paying. This is a minor nitpick on my part, and this motherboard at least has Wi-Fi 6E, which isn't far off. Regardless, you should want for nothing after paying more than five grand for this rig.
Performance Testing: More Frames for Fewer Dollars
Onward to benchmarking the beast. Against the Raptor Z55a we have a trio of desktops that are premium in both performance and pricing: the $6,999 Corsair Vengeance a5100 and its matching RTX 5090 and Ryzen 7 9800X3D combo; the $7,094 Falcon Northwest FragBox with its Ryzen 9 CPU and RTX 5090; and last, the $6,109 Alienware Area-51 with an RTX 5080 GPU and the only Intel CPU of the bunch.
Notably, the $5,609 Raptor is the most "affordable" rig in this Murderers' Row lineup, despite its high-power configuration. As the cheapest of the bunch, how does the Raptor Z55a hold its ground versus these other powerhouses? Pretty well, it turns out.

Productivity and Content Creation Tests
Our primary overall benchmark, UL's PCMark 10, tests a system in productivity apps ranging from web browsing to word processing and spreadsheet work. Its Full System Drive subtest measures a PC's storage throughput. Three more tests we run are CPU-centric or processor-intensive: Maxon's Cinebench 2024 uses that company's Cinema 4D engine to render a complex scene; Primate Labs' Geekbench 6.3 Pro simulates popular apps ranging from PDF rendering and speech recognition to machine learning; and we see how long it takes the freeware video transcoder HandBrake 1.8 to convert a 12-minute clip from 4K to 1080p resolution.
Finally, workstation maker Puget Systems' PugetBench for Creators rates a PC's image editing prowess with various automated operations in Adobe Photoshop 25.
On the productivity side, the Raptor Z55a kept pace with its competition but didn't blow away the field. The Raptor traded blows with its more expensive counterparts on some tests, winning two top spots (PCMark by a hair and a clear Photoshop victory) but trailing in other benchmarks. Alienware's Area-51 proved a formidable opponent with its Core Ultra 9, as did the mighty Ryzen 9 9950X3D in the FragBox on multiple benchmarks. More cores and threads gave those two PCs the clear edge in the apps that leverage those resources best (notably, Cinebench and HandBrake).
Keep in mind that all these scores are sky high, even if Velocity Micro’s PC placed second or third on some tests. These results indicate that the Raptor Z55a can just as easily serve as a heavy-duty video- and photo-editing workstation as a 4K/120fps gaming rig.
Graphics and Gaming Tests
We challenge all desktops' graphics with a quartet of animations or gaming simulations from UL's 3DMark test suite. Wild Life (1440p) and Wild Life Extreme (4K) use the Vulkan graphics API to measure GPU speeds. Steel Nomad's regular and Light subtests focus on APIs more commonly used for game development, like Metal and DirectX 12, to assess gaming geometry and particle effects. We then turn to Solar Bay to measure ray tracing performance in a synthetic environment. This benchmark pushes 3D scenes with increasingly intense ray-traced workloads at 1440p.
Our real-world gaming testing comes from the in-game benchmarks of Call of Duty: Modern Warfare 3, Cyberpunk 2077, and F1 2024. These three games—all benchmarked at full HD (1080p or 1200p), 2K (1440p or 1600p), and 4K (2160p) resolution—represent competitive shooter, open-world, and simulation games, respectively. Each game runs at high detail or the highest available settings: Extreme for Call of Duty, Overdrive for Cyberpunk, and Ultra High for F1 24.
We run the Call of Duty benchmark at the Extreme graphics preset on desktops. Because the test can produce triple-digit frame rates even on low-end PCs, this approach promotes sensible results to evaluate high frame-rate performance. Our Cyberpunk 2077 test settings aim to push PCs to their limit, so we run it on the all-out Ray Tracing Overdrive preset without DLSS or FSR. Finally, F1 2024 represents our DLSS effectiveness test (or FSR on AMD systems), demonstrating a GPU’s capacity with these frame-rate-boosting and upscaling technologies.
The Velocity Micro Raptor Z55a is simply a fantastic gaming machine. Our testing found it on par with Falcon Northwest's FragBox, a super-compact gaming rig that costs nearly $1,500 more, either edging out or close behind it across the 3DMark suite of synthetic 3D rendering tests.
The RTX 5090 inside the Raptor is overkill for casual or mainstream gaming, posting triple-digit frame rates without DLSS upscaling or frame generation at 1080p, 1440p, and 4K resolutions. We should say overkill for most, maybe, as the maxed-out 4K Cyberpunk 2077 results do demonstrate that the peak of PC gaming demands the card and then some. Of course, if you’re looking to save a little money, consider a configuration with the RTX 5080 if you're OK not sitting at the bleeding edge of the hobby.
