24-core i9-14900K liquid-cooled tower

This new desktop pairs a 24-core Intel Core i9-14900K processor with a 360 mm liquid cooler in a mid-tower chassis. It ships with Windows 11 Pro, 32 GB of DDR5 memory and 8 TB of NVMe storage across two Samsung 990 PRO drives. The GeForce RTX 5090 with 32 GB of video memory handles the graphics workload.

Suits 4K creators and high-refresh gamers.

The tower form factor and liquid cooling support sustained heavy loads for rendering, simulation or competitive play at high resolution. Buyers who need a small-footprint system or who plan to run multiple double-slot add-in cards should look at a different chassis layout.

32 GB video memory on the RTX 5090

That capacity determines whether large textures, frame buffers or compute datasets fit entirely on the card. The rest of the platform — 192 GB maximum system memory, PCIe 4.0 storage and a 1200 W Gold power supply — is specced to keep the GPU fed.

Questions about this item

Should I pick the single 8 TB NVMe option or the dual 4 TB Samsung 990 PRO RAID 0 array for my workload?

The system ships with two 4 TB Samsung 990 PRO drives in PCIe 4.0 x4, giving 8 TB total and sequential reads up to 7450 MB/s and writes up to 6900 MB/s.

What does the 6.00 GHz boost clock on the 24-core i9-14900K actually deliver inside this liquid-cooled tower?

The 360 mm AIO keeps the 24-core, 32-thread CPU at its 6.00 GHz max turbo under sustained loads, so single-thread and multi-thread performance stay at peak without thermal throttling.

How does the PCIe 4.0 x4 link cap the RTX 5090 and the 990 PRO SSDs in real use?

Both the GPU and each SSD run at PCIe 4.0 x4, so the RTX 5090 32 GB and the Samsung 990 PRO drives operate at their full rated bandwidth without being limited by the Z790 platform.
