Built for Gaming and Media Work

This desktop combines a 14-core Intel Core Ultra 5 245K processor with an Nvidia GeForce RTX 5090 graphics card. Liquid cooling keeps the CPU stable during long rendering or gaming sessions. It ships with Windows 11 Pro and 64GB of DDR5 memory for immediate use.

The GPU That Sets the Tier

The GeForce RTX 5090 carries 32GB of video memory, a figure that determines whether the system fits high-resolution texture workloads or multi-monitor setups. Builders who need more VRAM for offline AI training or 8K video timelines will find this ceiling fixed. No other graphics option is offered in this configuration.

Memory and Storage Headroom

Sixty-four gigabytes of DDR5 handles large project files and heavy multitasking with room to expand to 192GB across four slots. The 1TB Samsung 990 PRO NVMe drive delivers read speeds up to 7450 MB/s and writes up to 6900 MB/s, enough for active projects; additional M.2 slots and drive bays remain open for larger media libraries.

Questions about this item

How does the 14-core Intel Core Ultra 5 245K perform inside this desktop?

The 14-core Intel Core Ultra 5 245K runs at 4.2 GHz base and up to 5.20 GHz boost with 24 MB L3 cache, cooled by a 240 mm liquid AIO for sustained multi-threaded workloads.

What does the Thunderbolt 4 Type-C port on the Z890 motherboard actually limit?

Thunderbolt 4 caps at 40 Gbps for data and video, so external NVMe enclosures, dual 4K displays or high-speed docks hit that ceiling before the CPU does.

Will the RTX 5090 and 240 mm radiator fit in the Corsair 4000D case?

The Corsair 4000D measures 490 x 239 x 486 mm and supports a 240 mm front radiator plus full-length graphics cards, so the RTX 5090 and AIO install without modification.
