  2. Totally fanless for silent operation
  3. We build to your specification and deliver within 7 days
  4. Clean Build™ Promise and original OS+drivers supplied on DVDs

Get ready for truly immersive entertainment. The UltraPN51 Pro 5 Fanless is built with one of AMD’s Ryzen 5000 series processors, all encased in Akasa fanless Turing A50 MKII chassis. So whether you’re streaming the latest movie or need to finish that last minute presentation, you’ve got the performance to handle it with ease, while staying blissfully silent!. These systems support up to four 4K at 60 Hz monitors, one via the HDMI 2.0 port, two by utilising DisplayPort over USB-C, with the final display using the standard DisplayPort.

Even though the UltraPN51 is small in size, it is just as versatile as a full-sized computer. The HDMI and standard DisplayPort outputs provides full 4K resolution as well as 7.1 digital audio output, (a capable AV Receiver is required). There’s also two USB Type-C port that provides USB 3.1 for faster data transfer or the capabilities of connecting a further two monitors. It’s also possible when connecting the UltraPN51 to DP++ compatible devices to have a single 8K at 60Hz output, for resolutions four times greater than 4K!

Extensive Connectivity

For such a small chassis, you’d expect to see some lack of connectivity or compromises due to its size. In fact the UltraPN51 has an extensive range of front and rear ports available. Check the specifications table at the bottom of this page for more information.

Up to Eight Core Processing Power

The AMD Ryzen series processors are becoming the “go-to” CPU for virtually any personal computer. The processors in the UltraPN51 are AMD’s “U” suffix variants. The “U” denotes that the CPU is a lower power alternative to their desktop brothers and as such will consume less power and generate less heat. This makes them perfect for such a small environment.

The UltraPN51 can be configured with a choice of one of AMD’s excellent mobile processors. As you can see from the table below all CPUs offer different clock speeds. They also all feature “Turbo Frequency” allowing them to provide that extra performance when required. The Ryzen 3 is a quad-core processor, making it ideal as home or office PCs, the Ryzen 5 has 6-cores for more intensive tasks, while the Ryzen 7 is an 8-core processor, giving it more performance for more demanding jobs.

Wi-Fi and Bluetooth connectivity

Please note, that by default Wi-Fi and Bluetooth is not supplied with this systems. If you require them please make sure you choose the ‘Wi-Fi and Bluetooth Antennae Kit’ option in the configurator below.

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

The price of many pre-built PCs these days is often supported by cash kickbacks from software companies who pay hardware manufacturers to pre-install limited or trial versions of their software and then hope that the customer pays to upgrade to the full version. The downside to this approach is that the new PC comes pre-loaded with a lot of “junkware” which bloats the operating system and can cause severe performance degradation.

Here at Quiet PC we believe that customers have every right to expect the best possible performance from a brand new PC, so every system we build comes with our Clean Build™ promise. We install the operating system (if you order one), motherboard drivers, OS updates and Windows Security - that’s it. You won’t be pestered by pop-ups and nag screens and you can get on with using your new PC immediately without having to uninstall lots of junkware first. Your new machine will boot in super-quick time and will stay running quickly for many 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.
