Built for AI workloads and 4K gaming

This desktop pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 32GB GPU and 64GB of DDR5 memory. Windows 11 Pro is pre-installed on an 8TB NVMe array backed by a 10TB hard drive. A 360mm liquid cooler and 1200W 80 PLUS Gold power supply support sustained heavy loads.

Suits creators and researchers who need local

The specification serves users running large language models, complex rendering or simulation workloads that benefit from 32GB of VRAM and high core counts. Buyers who only require 1080p or 1440p gaming, lighter content creation or a smaller storage footprint will find the configuration excessive.

Deciding specification: GPU VRAM capacity

The RTX 5090 provides 32GB of video memory, which determines whether large models or high-resolution texture datasets fit entirely on the card. If your workflow stays below that threshold, a GPU with less VRAM reduces cost without sacrificing performance for your use case.

Questions about this item

Does the PCIe 4.0 x4 link on the Samsung 990 PRO SSDs limit real-world throughput?

Each drive is rated for sequential reads up to 7450 MB/s and writes up to 6900 MB/s, so the 4.0 x4 interface delivers those speeds in sustained transfers.

What clearance does the 360 mm liquid cooler require inside the Corsair 4000D case?

The 4000D supports a 360 mm radiator in the front, and the AIO is pre-mounted there with the 140 mm fans pulling air through the mesh panel.

How is the 64 GB DDR5 kit installed on the Z790 PRIME board, and what step is often missed?

The four modules fill all four slots; the step people forget is enabling the XMP profile in BIOS so the memory runs at its rated speed instead of the default JEDEC frequency.
