The Kyanite Z4 Gaming PC is the perfect choice for customers looking for a mid-sized, elegant and quiet PC while still being able to provide enough FPS for the most demanding of games. The PC is built around the Antec Dark Phantom Micro-ATX Gaming chassis, which offers excellent cooling at very low noise levels, as well as looking fantastic.

AMD Ryzen 9000 Series

The AMD 9000 series processors, built on the new ‘Zen 5’ core technology, form the powerhouse of this PC. These processors mark the next era of high performance for gamers, enthusiasts, and content creators, boasting impressive features such as up to 16 cores and 32 threads.

Compared to the 5000 series, the AMD 9000 series offers substantial improvements. They offers remarkable single-core performance improvement of up to +29%, granting a significant boost in tasks that rely heavily on single-core processing. Content creators can benefit from up to 45% more compute power, allowing for faster rendering and intensive workloads. Gamers can experience up to 15% faster gaming performance in select titles, ensuring smooth gameplay and responsiveness. Additionally, the 9000 series processors offer up to 27% better performance-per-watt, resulting in more efficient power usage.

To illustrate the performance gains of the AMD 9000 series processors over the 5000 series, the table below showcases some PassMark CPU Benchmarks. Higher numbers indicate better performance, providing you with an overview of the substantial improvements offered by the 9000 series processors.

The figures above are as of August 2024. They do change over time.

These advancements in performance make the AMD 9000 series processors an excellent choice for demanding tasks, gaming, and content creation, delivering exceptional speed and efficiency to enhance your overall computing experience.

The best quiet / performance balance

Any air-cooled PC will always be a compromise between quietness (arising from careful cooling design) and performance (which produces heat). This situation affects gamers even more than most because of course, the latest and greatest processors and 3D graphics cards tend to be the ones which run the hottest and which have the loudest fans on them.

We’ve done a lot of development work in this area to bring you a fully built high performance PC which we think offers the best of both worlds - virtually silent running (especially when the PC isn’t being used for gaming), and extraordinary gaming performance with great cooling design which gives total safety and reliability for your precious CPU and GPU.

Storage considerations

When specifying your new PC’s storage options using our system configurator below, you will be offered a choice of drives which vary by price and capacity. There are two primary types of storage. A conventional hard disk drive (HDD) offers huge storage capacity for a low price, but it won’t be especially fast and it will generate a certain amount of running noise since it contains a constantly-rotating spindle. A solid state (SSD) or a M2 drive on the other hand, offer tremendous speed and absolutely silent operation, but they cost more than an HDD for any given capacity.

So if you need a lot of storage space (for videos or large quantities of digital photos for example), then we would recommend an HDD. On the other hand, if you prefer silence and speed (especially boot-up speed), then an SSD or M2 drive would be a better choice. Of course you can have more than one drive, so you could have the best of both worlds by choosing one of each! We recommend that customers chose an SSD or M2 drive as a boot drive that contains the operating system and important programs and a conventional HDD to store other data, but remember that if you intend to have a totally silent PC you might want to forgo the HDDs all together as they will make some noise due to their moving parts.

Clean Build™ Promise

These days, many pre-built PCs often rely on cash incentives from software companies to support their prices. These companies pay hardware manufacturers to pre-install limited or trial versions of their software, hoping that customers will eventually opt to upgrade to the full version. Unfortunately, this approach has a downside: it fills the new PC with unnecessary “junkware,” leading to an inflated operating system and performance issues.

At Quiet PC, we firmly believe that customers deserve the utmost performance from their brand new PCs. That’s why we proudly offer our Clean Build™ promise with every system we build. When you choose one of our PCs, we install only the essentials: the operating system (if requested), motherboard drivers, OS updates and Windows Security. Say goodbye to annoying pop-ups and nag screens. With our clean build promise you can immediately start using your new PC without the hassle of uninstalling numerous unwanted programs. Experience lightning-fast boot times and enjoy optimal performance for months and years to come.

Free hardware support and fully inclusive warranty

We offer free hardware technical support for as long as you own the machine. This support covers any hardware query or problem, including advice on maintenance and upgrades. We regret we can’t offer software support or training so we would recommend contacting the software vendor in this instance.

Our hardware warranty runs for at least two years and is “collect and return” meaning that you don’t need to worry about getting the machine back to us - we will instruct our courier to collect it from you on a day of your choosing, then after we have checked and repaired it we will send it back to you by express courier at our expense. In addition, unlike many other PC suppliers, we have an “open-case” policy which means you are free to open the machine and perform your own minor modifications or upgrades without worrying that your warranty might be affected.
