Custom 4K Gaming PCs
Every 4K Gaming PC is built to order around your games, 4K monitor, graphics settings, performance requirements and budget. Explore the individually named configurations below, review their proposed technical specifications and tell us what you want from your system. We check component availability and compatibility, then agree your final specification and quotation with you before you commit.
Built Around Your Games and 4K Display
We build gaming PCs to order, not off-the-shelf or prebuilt systems. Each named 4K configuration has a proposed component specification that can be discussed and tailored to your games, target resolution, refresh rate, graphics settings and budget.
Built to order: We check component availability, compatibility, pricing and your requirements before confirming the final specification and quotation. Allow 1–10 working days from order for component sourcing, assembly, testing and preparation for dispatch.
4K gaming places substantial demands on the graphics card. Performance depends on the GPU, VRAM, processor, game engine, graphics settings, ray tracing, upscaling technology and monitor refresh rate. A 4K label is not a guarantee of a particular frame rate or that every game will run at maximum settings. Exact component models, availability and compatibility are checked before the final build is agreed.
Understanding the Components
Processor (CPU)
The CPU handles game logic, simulation, background tasks and other processing. At 4K resolution, the graphics card is often the main performance limit in visually demanding games, although CPU performance still matters for frame-time consistency, simulation-heavy titles and high-refresh-rate gaming. The selected CPU must be compatible with the motherboard, BIOS, memory and cooling system.
Graphics Card (GPU) and VRAM
The GPU is a central component in a 4K gaming system because it renders a much larger number of pixels than 1080p or 1440p. Graphics performance, VRAM capacity, ray tracing, texture settings and upscaling all influence results. Card dimensions, power connectors, cooling, case clearance and the manufacturer’s power requirements are checked for the final build.
Memory (RAM)
32GB DDR5 is a practical capacity for many modern gaming systems, while 64GB can be useful for gaming alongside streaming, content creation or other memory-intensive applications. System RAM and graphics-card VRAM serve different purposes. The memory kit must match the motherboard and processor platform, with supported speed and timings configured for stability.
Storage and Game Libraries
NVMe SSD storage supports fast system startup, game loading and file transfers. A 2TB drive provides more room for large games and updates, while 4TB can suit extensive libraries, recordings and applications. Storage capacity does not itself increase average frame rates, although a healthy, suitably fast drive helps the overall experience.
Motherboard, Socket and BIOS
The motherboard must support the exact processor and memory type. Socket compatibility alone is not enough: chipset, BIOS version, memory support, PCIe layout, M.2 slots, USB connections and networking are checked against the chosen parts. The final motherboard is selected as part of the complete compatible build.
Cooling, Airflow and Noise
4K gaming can place sustained loads on the graphics card and processor. Cooler capacity, case airflow, fan layout, dust filtration and component clearance affect temperatures and noise. A liquid cooler is only specified when appropriate to the selected processor, case and build requirements; it is not automatically necessary for every gaming PC.
Power Supply and Graphics Connections
The PSU is selected for the exact CPU, GPU, drives and other components. The assessment includes power demand, transient loads, native GPU connectors, cable routing, PSU quality and appropriate headroom. High-end graphics cards can have substantial power and connector requirements, so the exact model must be confirmed before the final specification is agreed.
4K Resolution, Refresh Rate and Graphics Settings
4K gaming normally refers to a 3840 × 2160 display. The performance required for 4K at 60Hz differs from the performance required for high-refresh-rate 4K. Ray tracing, game engine, graphics settings, upscaling and frame generation can all affect the experience. Tell us your monitor and the games you play so the final specification can be reviewed appropriately.
