The 8Pack Polaris is back with the latest and greatest hardware. On its third iteration, this extreme PC still has a plethora of powerful features, such as the dual water-cooling system, a titan-class GPU, and the magic 8Pack touch. Equipped with an Intel Core Ultra 9 285K CPU and NVIDIA GeForce RTX 4090 GPU, the hardware has been overclocked to maximum stable speeds by champion overclocker Ian “8Pack” Parry, himself. What’s more, the 8Pack Polaris MK2.5 sports the same stunning blue aesthetic that makes it the centrepiece of any gaming or workstation set-up.
The 8Pack Polaris MK2.5 has been crafted to provide the best possible performance for multi-monitor, workstation, and ultra-high resolution gaming set-ups. Whether you’re a content creator or streaming the latest AAA and VR games, this extreme PC can handle anything you throw its way.
For its foundation, the 8Pack Polaris MK2.5 is equipped with ASUS ROG Maximus Z890 Extreme motherboard, sporting an LGA 1851 socket as well as support for DDR5, WiFi 7, and PCIe 5.0. This motherboard ensures the stability of the Intel Core Ultra 9 285K CPU, cherry-picked for its titan-class performance capabilities. This 15th gen Intel processor utilises the innovative hybrid architecture first introduced in Alder Lake generation CPUs. Enhancing the technology further, Arrow Lake features greater efficiency and lower temperatures. Making use of this new headroom, 8Pack overclocks the CPU to 5.6GHz on the physical cores and 4.9GHz on the efficiency cores offering upto 10% improvements in multi-threaded workloads. In lighter loads such as gaming, speeds of upto 5.7GHz can be expected.
To optimise multi-tasking and efficiency, the 8Pack Polaris MK2.5 harnesses the power of DDR5 RAM. Equipped with 48GB of DDR5 RAM at frequencies of 8400MHz, this memory solution has been specifically chosen as this is the optimum capacity for rendering, coding, and other intensive tasks. All whilst still offering the best overclocking potential and energy efficiency.
The 8Pack Polaris MK2.5 harnesses the power of the new RTX 40 Series, equipped with their flagship NVIDIA GeForce RTX 4090 GPU. Utilising next-gen RTX architecture Ada Lovelace, this extreme PC will render your games and images in photo-realistic quality, with AI-enhanced capabilities such as ray tracing and DLSS 3. Perfect for gamers and creators who want the very best out of their GPU.
To help maintain optimum temperatures, the graphics card has its own dedicated cooling loop. As such, the 8Pack Polaris MK2.5 remains cool and quiet.
In fact, the 8Pack Polaris MK2.5 operates with two custom water-cooling systems. There is a primary cooling loop, as well as the dedicated loop for the graphics card. This unique thermal solution is crafted with premium-quality components, such as hard-tubing, bespoke 8Pack branded distro plates, and high-performance radiators. Even the case has been optimised for phenomenal natural airflow, with extensive support throughout the chassis for cooling hardware.
Overall, the 8Pack Polaris MK2.5 thermal system has been designed to provide twice the cooling power needed, to maximise overclocking headroom. This extends the life of all the titan-class components. It looks great, too! Featuring coloured coolant and illuminated by RGB lighting, the dual water-cooling loops are a work of art. It’s not an 8Pack PC until the cooling system is a centrepiece of its design!
To ensure you have ample space for your gaming library and media files, the 8Pack Polaris MK2.5 features two Samsung 980 Pro NVMe SSDs. Both 1TB in capacity, they have been configured as the primary and secondary storage drives, to optimise loading times and fetch rates.
Powering the 8Pack Polaris MK2.5 is the very power supply that 8Pack designed in conjunction with SuperFlower, the Leadex 8Pack Edition PSU. This beast has an 80 PLUS Titanium rating – that is 96% efficiency at half loads – and delivers 2000W of power. Just what you’d expect from something with 8Pack’s name on it.
As always with an 8Pack machine, there are customisable options available for the aesthetic. Water cooling fittings can be changed, as well as the colour on the coolant. The braided cables can also be colour-matched to any adjustments you make. Please get in contact with our Prestige System Advisor prior to purchase to discuss any changes you want to make.
