GPU 5090

CPU U9 285K

  • Intel Core Ultra 9 285K reaches 5.7 GHz turbo for responsive compute
  • NVIDIA RTX 5090 with 32 GB GDDR7 drives high-fidelity gaming and AI workloads
  • 64 GB DDR5 6000 memory sustains multitasking and creative throughput
  • 2 TB Gen5 NVMe SSD loads games and projects fast

Built for AI workloads and 4K gaming

This desktop pairs an Intel Core Ultra 9 285K processor with an NVIDIA GeForce RTX 5090 graphics card holding 32 GB of GDDR7 memory. The system targets creators and enthusiasts who need local AI acceleration alongside high-frame-rate 4K play. Windows 11 Home 64-bit is pre-installed on the 2 TB Gen5 NVMe SSD.

Capacity and headroom

Sixty-four gigabytes of DDR5 6000 memory provides ample space for large language models, heavy multitasking and complex creative timelines. The 2 TB NVMe drive holds the operating system and active project files, though users with extensive media libraries will need secondary storage. The 1200 W ATX 3.0 power supply delivers stable current for the GPU and CPU under sustained load.

What the bundled cooler and software change

A 420 mm AIO liquid cooler with ARGB fans keeps the Ultra 9 285K at 3.7 GHz base and 5.7 GHz turbo clocks during long renders. Intel AI Boost built into the CPU handles real-time video and voice optimisation for streaming and conferencing. NVIDIA Tensor cores and DLSS 4 on the RTX 5090 accelerate Stable Diffusion, image enhancement and high-refresh gaming without extra configuration.

この商品に関する質問

Will my existing PCIe 4.0 NVMe SSD work in the Z890 motherboard alongside the 2TB Gen5 NVMe?

Yes, the Z890 board supports PCIe 4.0 drives so your older NVMe SSD will function normally next to the 2TB Gen5 NVMe.

How can I confirm the 64GB DDR5 6000 memory is running at its rated speed after first boot?

Open Task Manager or enter the BIOS and verify the memory frequency reads 6000 MT/s.

Does the 1200W Gold ATX 3.0 power supply include the 12VHPWR cable needed for the RTX 5090 32GB GDDR7?

The 1200W Gold ATX 3.0 unit ships with the native 12VHPWR connector required by the RTX 5090.
