What makes a great gaming PC?

Building a great gaming PC requires intimate knowledge of not only the components themselves but also a deep knowledge about how well they perform together. Our engineers have dozens of years’ experience crafting award-winning systems, following these principles.


The CPU or processor is the brain of the PC, and coordinates and processes every command you issue your PC, from booting up Windows, to running and playing games. A more powerful CPU makes everything happen faster, making the system more responsive. Choosing a more powerful CPU will also allow you to do more with your PC, such as creating videos and music.

graphics card

The GPU or graphics card is the eyes of the PC, processing the incredibly complex calculations that render the beautiful graphics you see when playing a game. A more powerful GPU will render games at a higher frame rate, making the on-screen action smoother and resulting in a much more enjoyable experience.


The RAM or memory is the temporary storage medium used to cache data when playing games. Adding more RAM to a system will make games load quicker or multitask between several Windows applications at once.

solid state drive

An SSD or solid state drive is the permanent storage for a gaming PC, storing Windows, games and applications. SSDs transfer data at over four times faster than an traditional HDD or hard disk drive, so games and applications load faster, giving you more time to enjoy your PC. As an added bonus SSDs are totally silent and don’t clatter like a mechanical HDD.

power supply unit

The PSU or power supply unit converts mains 230W AC from the wall to the 12V DC that the components inside the PC require. Choosing a good quality PSU will result in a more energy efficient and quiet PC with less power going to waste.


It’s also important to choose the right motherboard, as this component connects every inside the PC together, enabling them to communicate efficiently. A good quality motherboard will speed up communication and allow more devices to be connected to build a higher performance, more capable system.


The case is the skeleton of the PC, to which every component is attached via screws. The case also helps to keep the PC clean, keeping out dust and protecting the delicate electronic components from physical damage. While mostly performing a cosmetic function, a good quality case will help to keep a gaming PC cool and quiet, making for a more pleasurable user experience.

Cooling devices

A gaming PC will need some cooling devices, such as a heatsink or watercooler to keep the CPU and GPU cool, plus some fans to suck cool air into the case and blow hot air out. Good quality coolers will result in a quieter PC and provide headroom for overclocking, the process our engineers use to boost performance even further.

Gaming Peripherals

To make the most of your gaming PC you’ll also want to invest in some decent gaming peripherals. A high quality monitor, especially one with NVIDIA G-Sync technology that synchronises the refresh rate of the monitor with the frame rate of the graphics card is a must have. The humble keyboard and mouse shouldn’t be underestimated either, with a massive range to choose from, optimised for different games, including keyboards with mechanical switches that provide tactile feedback when typing. For online gaming a headset is also a necessity, allowing you chat with friends and team mates.

Our Build Process

Many gamers are early adaptors and want the latest technology as soon as it is available. Working closely with our key partners we have developed a Just in Time build process where we individually build each customers PC in as little as 5 working days. This JIT process ensures we can rapidly respond to technology changes as are not stuck with excess stock generated by batch building PCs.

How we do it

Our engineers don’t just build PCs; each of our systems is hand-crafted, using the finest quality components. For instance, we route and tidy all the cables around the sides of the case. This not only makes your PC look great and easier to upgrade in the future, but eases airflow through the case resulting in a cooler and quieter PC.

Key Partners

Unlike other PC manufacturers we don't believe in fobbing off our customers with unbranded components. We're just as demanding as you are and expect our PCs to work reliably for years. For this reason we have over the years built up close relationships with key partnerships, ensuring that your 3XS PC is built using latest and the finest quality components.

Scan is an Intel Platinum Technology Partner and our director Elan Raja is President of the Intel Board of Advisors. The largest CPU manufacturer in the world, Intel Core i3, Core i5, Core i7 and Xeon processors form the core of our 3XS systems. Choose an Intel CPU for the ultimate performance, power efficiency and reliability. We also use Intel SSDs in our high-end desktops, workstations and servers.

Whatever you use your PC or laptop for you'll need Microsoft Windows. Scan is a Microsoft Silver OEM Partner and is one of only seven direct Microsoft accounts in the UK.

Scan has a close partnership with NVIDIA and is the UK’s exclusive launch partner for new products. Scan recommends NVIDIA GeForce graphics cards in our gaming PCs and laptops and NVIDIA Quadro cards in our professional graphics workstations. Scan also produces multi-monitor workstations for traders using NVIDIA Quadro NVS cards, accelerated VDI servers using NVIDIA GRID, and NVIDIA Tesla GPU accelerators for HPC applications.

Corsair produces a wide range of innovative products such as memory modules, power supplies, cases, CPU coolers plus peripherals such as keyboards, mice and headsets. Scan 3XS systems exclusively use Corsair memory modules as they perform the best and are extremely reliable.

Intensively tested

Building a PC only takes a few hours, but installing all the software and making sure that everything is configured properly and that your software runs stably takes up a huge amount of time. By ordering a 3XS system our engineers take this painful process away, as all our systems undergo a strenuous Quality Control procedure which includes updating Windows, installing the latest drivers and motherboard BIOS. Overclocked systems receive an additional 24 hour burn-in test to ensure stability.

VR Ready

VR PCs take your gaming to the next level with a Virtual Reality headset that immerses you completely in the game world. These high performance VR Ready PCs feature the best NVIDIA GeForce graphics and Intel Core i5 and i7 processors to deliver a smooth experience with Virtual Reality headsets such as the Oculus Rift and HTC Vive. Whether you’re playing VR friendly games such as Elite Dangerous or developing games these systems have been specially designed to give you the ultimate VR experience.

Awards and Service

Peace of mind

Unfortunately PC components do occasionally fail, and when this happens if you’ve built your PC yourself you’re on your own. However, with a professionally built Scan 3XS system you’re no longer alone. Our technical support team is available 7 days a week, from 9am to 10pm Mon - Fri, 10am to 6pm on Saturdays and 10am to 4pm on Sundays.
