BattleBox Pro ExtremeRTX 5080 · Ryzen 7 9850X3D
A showcase-class build for players and creators who want elite frame rates and a machine worth looking at. The NVIDIA GeForce RTX 5080 16GB sits alongside the AMD Ryzen 7 9850X3D and its 104MB 3D V-Cache array, cooled by the NZXT Kraken Elite 240mm and eight cableless Lian Li Uni Fan SL Wireless fans.
All of it lives behind the three-sided seamless tempered glass of the Lian Li O11 Vision Compact, with an integrated 9.16" full-colour LCD screen for live system telemetry. Assembled, stress tested and backed by our technicians here in the UK.
Inside the Build
No filler parts and no surprises. Here is what each piece does and why it is in here.
AMD Ryzen 7 9850X3D
Eight cores, sixteen threads and a 104MB cache array built on AMD's 3D V-Cache technology, boosting up to 5.6GHz.
That stacked cache is the reason this chip is in here. Games spend a lot of their time waiting on data, and a larger cache means the processor finds what it needs without going out to memory. The result you actually notice is fewer frame-time spikes, which is what makes a high frame rate feel smooth rather than just look high.
GeForce RTX 5080 16GB
This is the part that draws the picture. Built on NVIDIA's Blackwell architecture with a 16GB frame buffer to itself, enough room for high-resolution texture packs and path-traced scenes.
Two things it does especially well. Ray reconstruction lights a scene the way light actually behaves. DLSS 4 renders the frame at a lower resolution, rebuilds it sharp with AI and generates extra frames in between, so you get the detail of maximum settings at the frame rate of low ones.
NZXT Kraken Elite 240mm
A closed liquid loop. Coolant picks up heat from the processor, carries it to a 240mm radiator and two fans push it straight out of the case.
It is a far bigger cooling surface than an air tower of the same footprint, so the 9850X3D holds its boost clocks through a long session instead of easing off as things warm up. The round LCD on the pump face shows live temperatures, or whatever image you would rather look at. Premium thermal paste is applied by hand on every build.
ASUS TUF Gaming B850-E WiFi
The board everything plugs into. TUF is ASUS's durability line, built with tougher components and stronger power delivery than a standard board.
It is PCIe 5.0 ready, so it can take faster graphics cards and drives as they arrive. Wi-Fi 6E and Bluetooth are built in, and there is 2.5GbE wired networking for when you want the lowest possible ping. Being AM5, it will also take a future AMD processor without replacing the board.
32GB DDR5 at 6000MHz
Memory is where the game keeps everything it might need in the next few seconds. 32GB is enough to play, stream, capture, run Discord and leave a browser full of tabs open without any of it fighting for room.
Running at 6000MHz in dual channel, it is the speed the Ryzen platform is happiest with. Quick answers to the processor show up as fewer sudden dips in demanding scenes.
2TB NVMe M.2 SSD
Windows boots in seconds and games load in a fraction of the time an older drive would take. Open world titles stream scenery in as you move, so you do not get textures filling in when you turn a corner quickly.
2TB gives room for a large library, capture footage and creative projects without having to manage space carefully, and the board has a spare M.2 slot if you ever want a second drive.
Lian Li O11 Vision Compact Black
Three seamless panels of tempered glass with no corner pillar, so the build is visible from the front and both sides rather than through a single window.
The integrated Vision 9.16-inch full-colour LCD screen sits in the chassis itself and can show temperatures, clocks and fan speeds live, or run your own artwork. Eight Lian Li Uni Fan SL Wireless 120mm fans handle airflow, and because they are cableless the interior stays clean enough to be worth showing off.
Corsair RM850e 850W
Clean, steady power for everything above, with an 80 PLUS Gold rating. It wastes less energy as heat, so it runs cooler and costs less to leave on.
It is fully modular, meaning we only fit the cables this build actually uses. Nothing spare is stuffed behind the tray, airflow stays clear and the low-noise 120mm fan stays quiet. 850W also leaves genuine headroom above the RTX 5080's draw for spikes and future upgrades.

What Can It Run?
The BattleBox Pro Extreme puts AMD's 3D V-Cache behind NVIDIA's Blackwell generation, a pairing aimed at players who want maximum refresh rates at 1440p and ultra settings at 4K without compromising on either. The 104MB cache array on the Ryzen 7 9850X3D targets frame-time stutter directly, so the frame rate stays as steady as it is high.
In competitive titles your monitor becomes the limit rather than the PC. Counter-Strike 2, Valorant, Apex Legends and Fortnite all run comfortably past what a 360Hz panel can display, and because the 3D V-Cache smooths out frame-time spikes, the frames arrive evenly instead of in bursts. That is what keeps your aim predictable.
Step up to the heavy releases and the RTX 5080 does the work. Cyberpunk 2077, Black Myth: Wukong, Alan Wake 2 and Call of Duty all play at ultra with ray tracing switched on, using DLSS 4 and frame generation to hold the frame rate up rather than turning detail down. 4K at ultra is a realistic everyday setting here, not a stretch goal.
With 32GB of DDR5 6000MHz memory, nothing has to be closed to make room. Game, stream, capture, Discord and a browser full of tabs coexist without the system starting to stutter, and the 2TB NVMe drive keeps a large library installed with fast level loads across all of it.
Outside of games it doubles as a serious workstation. Blender and Unreal Engine 5 renders, multi-track 4K timelines in DaVinci Resolve or Premiere and local AI workloads all sit well within what the 16GB RTX 5080 and this processor handle day to day.
FPS Benchmarks
Typical average frame rates for this configuration at 1440p and 4K ultra settings. A busy scene and a quiet one are not the same test, so treat these as the shape of the performance rather than a fixed number.
| Game Title | Settings | Avg. FPS |
|---|---|---|
| Cyberpunk 2077Open World / Cinematic | 1440p Ultra · Ray Tracing On · DLSS 4 | 165+ FPS |
| Black Myth: WukongAction RPG | 1440p Cinematic preset | 135+ FPS |
| Call of Duty: Black Ops 6First-Person Shooter | 1440p Extreme preset · DLSS Off | 210+ FPS |

Frequently Asked Questions
What resolution is this PC designed for?
The BattleBox Pro Extreme is built for maximum-refresh 1440p and ultra settings at 4K. Competitive titles run far beyond what even a 360Hz panel can display, while heavy AAA releases hold high frame rates at 4K with ray tracing on, using DLSS 4 and frame generation where supported.
What does the 3D V-Cache on the Ryzen 7 9850X3D actually do?
It stacks extra cache directly onto the processor, giving it 104MB in total. Games constantly request small pieces of data, and a larger cache means the chip finds them without waiting on system memory. The benefit you notice is fewer frame-time spikes, which is what separates a frame rate that feels smooth from one that just reads high.
Does the graphics card support ray tracing and DLSS?
Yes. The GeForce RTX 5080 16GB has dedicated ray tracing cores for realistic lighting, shadows and reflections, plus tensor cores that run DLSS 4 with advanced ray reconstruction. DLSS uses AI to reconstruct and generate frames, giving a large frame rate increase while keeping the image sharp, even at 4K.
What is the 9.16-inch LCD screen on the case for?
It is built into the Lian Li O11 Vision Compact chassis and can display live system telemetry such as CPU and GPU temperatures, clock speeds and fan speeds. You can also load your own images, animations or wallpapers onto it. The Kraken Elite pump face is a second, separate display you can configure the same way.
How loud is it with eight case fans?
Quieter than you would expect. Eight fans moving air gently is quieter than two fans working hard, and the Uni Fan SL Wireless units are tuned for airflow at low speeds. The 240mm radiator gives the cooling loop an easy job and the RM850e's fan stays off at light loads. Expect it to be audible under a sustained gaming load, not intrusive.
Is 2TB of storage enough, and can I add more?
2TB comfortably holds Windows plus a large modern game library, capture footage and creative projects. If you need more later, the motherboard has additional M.2 NVMe slots and SATA connections for extra drives.
Can I upgrade the PC in the future?
Yes. Everything in here is a standard part. The AM5 socket takes future AMD processors, there is a free M.2 slot and spare memory capacity, the case has room for a larger graphics card and the 850W supply leaves headroom for one.
Does this PC support Wi-Fi and Bluetooth?
Yes. The ASUS TUF GAMING B850-E WIFI motherboard includes Wi-Fi 6E wireless networking and Bluetooth, with external antennas supplied. There is also a 2.5GbE Ethernet port if you would rather use a cable.
Is this PC suitable for streaming and content creation?
Yes. The Ryzen 7 9850X3D, 32GB of DDR5 and the 16GB RTX 5080 handle streaming and capture alongside gaming with no dropped frames, and the same hardware is well suited to video editing, 3D rendering and local AI work.
Does the PC come with Windows installed?
Yes. Windows 11 Professional is pre-installed, configured and tested before dispatch, so your system is ready to use immediately.
How is the PC tested before shipping?
Every BattleBox Pro Extreme goes through a full build and quality assurance process. This includes BIOS updates where applicable, cable management, thermal testing, hardware stress testing, driver installation and a final inspection before the system is carefully packaged for delivery.
What warranty is included?
The BattleBox Pro Extreme includes a 3 Year Standard Warranty, consisting of:
- 1 Year Collect & Return
- 1 Year Parts Warranty
- 3 Years Labour Warranty
- Lifetime Technical Support
