Built for 4K and heavy multitasking

This pre-built desktop pairs an Intel Core Ultra 9 285K 24-core processor with an NVIDIA GeForce RTX 5090 graphics card. It ships with Windows 11 Home, 128GB of DDR5 memory and a dual-drive layout of 2TB NVMe plus 2TB SATA storage. The 240mm liquid cooler and 1200W power supply support sustained high-wattage operation.

32GB GDDR7 on the RTX 5090

The graphics card carries 32GB of GDDR7 video memory, a capacity that determines whether the system can hold large 4K textures and heavy compute datasets without swapping to system RAM. Buyers who need more VRAM for extreme workloads should look elsewhere.

Liquid cooling and 1200W headroom

A 240mm liquid cooler manages CPU thermals while the 1200W unit delivers stable power to both the 285K and the RTX 5090 under continuous load. This combination keeps clocks high during long rendering or gaming sessions rather than throttling after a short burst.

Questions about this item

What does the 5.7 GHz figure mean when the Core Ultra 9 285K is inside a complete PC?

The 5.7 GHz is the processor's base frequency. In this system the 24-core chip runs at that speed across all cores, backed by a 240 mm liquid cooler and a 1200 W power supply so the clock can be sustained under load.

The RTX 5090 uses a PCI Express x16 slot — what does that interface cap in practice?

The graphics card connects through a full PCI Express x16 link, giving the RTX 5090 its maximum available bandwidth for the 32 GB GDDR7 memory and GPU compute.

What does the 240 mm liquid cooler need to fit inside the ASUS TUF GT302 case?

The 240 mm radiator mounts in the GT302 chassis with standard fan positions, and the closed-loop cooler arrives pre-filled and installed on the LGA 1851 socket.
