Extreme CPU performance you won't find just anywhere. This system utilizes Intel's Socket 3647 and new 28 core Xeon W-3175X and W-3275 to combine incredible compute power for multithreaded applications with extreme clock speeds for frequency dependent processes. The one-of-a-kind ProMagix™ HD150i also features up to 64 PCIe lanes and six channel ECC memory support up to 2TB total, making it the optimal platform for expandability and scalability for any CPU intensive activity.

We're able to custom overlock the Xeon W-3175X to best suit your workflow with lower overclocks across all cores or high clocks on a smaller number - simply tell us what you'd like. This process makes the ProMagix HD150i one of the fastest, most record shattering desktops that we’ve ever created. Whether it’s seamless digital editing, faster renders, or quicker data calculations that you’re after, the ProMagix HD150i delivers it all. You won’t find a faster, better performing system for CPU intensive tasks.


With an Asus Dominus Extreme motherboard and dual power supplies, the HD150i is not like other PC's. That's why use only the very latest premium retail grade parts alongside the Xeon W like DDR4 ECC Memory, NVMe hard drives, and premium graphics in the ProMagix HD150i for maximum performance and reliability. Each component is hand selected and meticulously assembled by our team of experienced engineers. When you make a part selection in our custom configurator, it has already been tested, verified, and approved to meet our standards.


With the Xeon W-3175X and W-3275's unique combination of processor core speed and core count, the HD150i is designed to shatter CPU intensive benchmarks and make you reconsider what a desktop PC can be. Not convinced? Check out this benchmarking video we put together to show off some of this system's prowess in Cinebench. They're some of the highest scores we've seen...and that's saying something.

Before we ship your system, we triple-check everything to make sure it will be the best PC you've ever owned. Our industry-leading testing includes a full week of benchmarks, tuning, and extensive reboots. Finally, we check cable management and connections with a 200-point QA checklist. Only then will a senior engineer sign off on your rig and approve it for shipping.

Sure, it’s more work. But no one ever said that creating something this remarkable would be easy...

Every Velocity Micro PC comes with complimentary lifetime business hours phone support. And the best part – a call placed to our expert, non-tiered support team will never be routed anywhere offshore. Not ever. It’s like having your own personal geek, just a phone call away.

It costs us more, but we refuse to let anything get in the way of an astonishing customer experience.
