Core Specification

This Adamant Custom desktop pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 carrying 32GB of video memory. The system ships with 64GB of DDR5 RAM, a 4TB NVMe SSD and a 10TB hard drive. It targets creators and researchers who need high single-thread speed plus massive parallel throughput for rendering, modelling and AI workloads.

Sustained Load Behaviour

A 360mm liquid cooler and a 1200W 80 PLUS Gold power supply keep the CPU and GPU fed during long compile, training or export sessions. The Z790 motherboard provides stable power delivery across all 24 cores while the Samsung 990 PRO maintains sequential reads up to 7450 MB/s and writes up to 6900 MB/s without thermal throttling.

Upgrade Context

The platform supports up to 192GB of DDR5 across four slots, so memory can be tripled when datasets outgrow the factory 64GB. Three additional M.2 connectors and two 3.5-inch bays allow further NVMe or SATA expansion without replacing the chassis. The jump is worth it when current hardware cannot hold active projects in RAM or saturates a single GPU.

Questions about this item

How loud is the 360 mm liquid cooler and 1200 W PSU fan when the i9-14900K runs at 6.00 GHz all day?

The CPU uses a 360 mm Quiet Edition AIO and the Thermaltake 1200 W Gold unit has a 140 mm ultra-quiet fan; both are designed for low noise under sustained load.

Do I need to buy a monitor, keyboard and mouse separately to use this PC?

Yes — the system ships with no screen and no peripherals, so you must provide your own display and input devices.

Can I keep my older SATA SSDs and mechanical drives alongside the 4 TB NVMe and 10 TB HDD?

The Z790 board offers four SATA 6 Gb/s ports and the case has two 3.5″ and two 2.5″ bays, so existing SATA drives fit without adapters.
