Built for intensive workloads

This Adamant Custom tower pairs a 24-core Intel Core i9-14900K with 128GB DDR5 and a GeForce RTX 5090 32GB GPU. Liquid cooling and a 1200W 80 PLUS Gold PSU support sustained performance. Windows 11 Pro 64-bit is pre-installed for immediate deployment.

GPU memory defines AI and rendering capacity

The RTX 5090 provides 32GB of video memory, which determines whether large models, high-resolution textures or complex scenes fit in VRAM. A 1TB Samsung 990 PRO PCIe 4.0x4 NVMe drive delivers read speeds up to 7450 MB/s and write speeds up to 6900 MB/s for fast asset streaming.

Suits creators and researchers needing maximum

Buyers who need more than 128GB system memory should note the motherboard supports up to 192GB DDR5 across four slots. The single-GPU design limits multi-card scaling for distributed training. Users requiring ECC memory or dual-socket configurations will need a different platform.

Questions about this item

What real-world difference does the 24-core i9-14900K make for heavy rendering or AI workloads?

The 24 cores and 32 threads let you run multiple compile, simulation or model-training jobs at once without waiting for a queue, and the 6.00 GHz peak clock keeps single-threaded stages responsive.

How fast can the Samsung 990 PRO 1 TB drive actually move data over its PCIe 4.0 x4 link?

Sequential reads reach 7450 MB/s and writes reach 6900 MB/s, so large project files and game assets load in seconds rather than minutes.

Will the 360 mm liquid cooler and RTX 5090 both fit inside the Antec P20 case without clearance issues?

Yes — the case supports 360 mm radiators up front and has 469 mm depth, giving the triple-slot RTX 5090 and the AIO plenty of room.
