i9 13900K /F - Intel's fastest desktop processor.

24 Cores (8 Performance & 16 Efficient) - 32 Threads - for Maximum multi-tasking and performance.

Superior Performance When You Need It*. Multitasking Like You’ve Always Wanted.

Our fastest gaming computer features the latest 13th Gen Intel Core processors—a generation like no other before it. With unprecedented new performance hybrid architecture, 13th Gen Intel Core CPUs offer a unique combination of Performance and Efficient-cores. And that means real-world performance, intuitively scaled to match whatever you’re doing1.

The Performance-core is Intel’s highest performing CPU core ever. And it’s designed to maximize single-thread performance and responsiveness for compute intensive workloads like gaming and 3D design. The Efficient-core delivers multithreaded performance for tasks that can run in parallel (like image rendering), along with efficient offload of background tasks for modern multitasking.

So that Performance-cores and Efficient-cores can work seamlessly with the operating system, Intel built Intel Thread Director right into the hardware2. Automatically monitoring and analysing on-the-fly, Intel Thread Director guides the operating system, helping it place the right thread on the right core, at the right time. And it does it all dynamically, adapting scheduling guidance based on actual computing needs, not on static rules.

With 13th Gen Intel  Core CPUs, standard, built-in features enable capabilities like noise suppression, auto-framing, and optimization for bandwidth and video resolution while gaming3. That saves you time and lets you multitask in ways you’ve only ever dreamed of—until now.

From epic gaming to browsing to streaming to creating your next masterpiece, 13th Gen Intel Core i9 13900K /F processor make it all entirely doable.

ASUS DDR5 Motherboard with Intel Z790 Series Chipset

Show More

ASUS is the world's biggest motherboard manufacturer, and renowned for its design thinking that revolves around users – just like you. Their engineers employ exacting standards to guarantee quality throughout the product's life, choosing the finest components for real-world protection. ASUS gaming PC motherboards are proven to be compatible with more than 1,000 components and devices, and undergo a minimum of 8,000 hours of strict validation. That gives you the peace of mind of knowing that ASUS gaming computer motherboards are fit for all environments and applications. To build your gaming PC with the best foundations, build it with an ASUS gaming computer motherboard.

All-round protection provides the best quality, reliability, and durability

We use ASUS motherboards on our gaming desktop PCs. 8000+ validation hours - Extensive testing for extreme reliability, compatibility and safety. ASUS motherboards guard your gaming PC with 5X Protection. We use quality components like DIGI+ VRM digital power design for precise CPU power on demand, ESD units tested to strict standards that eliminate electrostatic interference, and resettable fuses around DRAM slots to prevent overcurrent and short-circuit damage. We also use corrosion-resistant back I/O shields, all examples of ASUS providing the best possible reliability and durability for your gaming computer.


32GB DDR5 Dual Channel Gaming RAM with Heatsink.

Show More

While other PC shops use DDR4 RAM on their fast gaming computers, we use the latest and faster DDR5.

DDR5 is the next evolution of PC main memory.

Energise your Ultimate Gaming PC With Dual Channel. The data path is doubled by using two sticks of DDR5 memory. By giving the CPU/north bridge another data path to the memory, bandwidth is effectively doubled. In simple terms, think of Dual Channel DDR5 as widening the bridge by adding two more lanes. This effectively allows more data to travel faster; much like traffic moving faster when there’re more lanes to drive in.

We use A-Grade RAM in all our gaming computers such as Corsair and Kingston.

Hi Brett

Total War Three Kingdoms just released not too long ago and it was the game I was looking forward to play the most this year, with the computer the game ran very very smooth! Couldn’t be more happier getting heaps of FPS on high to ultra settings.

Very pleased with the computer, no problems encountered so far and i hope i never have to anyway.

Apologise for the late reply (it was long due indeed) was waiting for the Total War game to release first before I let you know my overall impression.

Anyhow wishing you and your team much success this year. Really appreciate your customer friendly attitude it truly fits our motto “Excellence, Simply Delivered”. Please keep up the great work as always, will be missing much of your work as times flies by.
