Liquid-cooled gaming desktop with a 14-core Intel Core Ultra 5 245K, 128GB DDR5, 4TB NVMe storage and an RTX 5070 Ti 16GB GPU
This desktop combines a 14-Core Intel Core Ultra 5 245K with 128GB DDR5 and an RTX 5070 Ti 16GB GPU. It targets professionals who run local AI models, heavy multitasking workloads and high-resolution content creation. The Z890 platform and liquid cooling keep the platform stable during extended sessions. Buyers who need more GPU memory or a second graphics card should look elsewhere.
The 4TB Samsung 990 PRO NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s over a PCIe 4.0 x4 link. That throughput determines whether large project files, model weights and scratch disks load without stalling the CPU. If your workflow demands sustained write speeds beyond this ceiling, this drive will become the bottleneck.
A 240mm AIO liquid cooler handles the CPU while the Thermaltake 850W 80 PLUS Bronze PSU powers the full system. Under continuous multi-core and GPU compute, the liquid loop maintains lower temperatures than air alternatives, reducing thermal throttling risk. The case includes three 120mm front fans and dust filters to support airflow over long renders or training runs.

Fourteen cores and a 5.20 GHz maximum turbo give strong multi-thread throughput for rendering, compilation and AI workloads while keeping single-thread speed high for gaming.
Thunderbolt 4 caps at 40 Gbps and the 20 Gbps Type-C ports at 20 Gbps, so external NVMe enclosures or docks will not exceed those ceilings.
The 240 mm AIO mounts in the top of the 469 mm deep P20, leaving length clearance for the graphics card and height clearance for all four memory slots.
