ArsenalPC AP202 White Gaming Desktop

This ArsenalPC system pairs an Intel Core Ultra 9-285K processor with an NVIDIA GeForce RTX 5080 graphics card for high-end gaming and creative workloads. It arrives with 128 GB of DDR5 memory configured as four 32 GB modules and a 4 TB NVMe solid-state drive. The build is housed in a white ASUS Prime AP202 chassis with a 360 mm liquid cooler that includes an LCD display. A 1000 W power supply and Windows 11 Home complete the package.

Suits AI developers and 4K enthusiasts

The 24-core processor and RTX 5080 GPU deliver strong throughput for local model inference, image generation and high-refresh 4K gaming. Builders who need ECC memory support or a workstation-grade driver stack should look at certified workstation platforms. Buyers who want more storage than 4 TB or prefer a smaller form factor will need a different chassis configuration.

128 GB DDR5 memory capacity

The system ships with four 32 GB DIMMs filling every slot on the Intel LGA 1851 platform. This density supports large dataset loading and heavy multitasking without paging. If your workflow demands more than 128 GB of RAM, this motherboard cannot accommodate it.

Questions about this item

Should I choose the 128GB DDR5 kit or a smaller capacity for this Core Ultra 9 285K build?

The 128GB DDR5 kit (32GB x 4) fills all four DIMM slots on the LGA 1851 platform, giving maximum capacity for AI workloads and heavy multitasking without leaving room for later upgrades.

What does the 5.7GHz boost clock on the Core Ultra 9 285K actually deliver in daily use?

The 24-core processor hits 5.7GHz on thermal headroom, so single-thread bursts stay fast while the 360mm liquid cooler with LCD keeps sustained all-core loads stable during rendering or model training.

How does the RTX 5080 with GDDR7 connect to the rest of the system and what does that limit?

The GPU runs on the platform's PCIe lanes alongside the 4TB NVMe SSD and 2.5G Ethernet, so storage and network traffic share bandwidth but the 1000W supply ensures stable power for peak graphics loads.
