Core configuration

The Adamant Custom tower pairs a twelve-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card, 64GB of DDR5 memory, an 8TB NVMe array and a 10TB hard drive. Windows 11 Pro is pre-installed on the solid-state storage. Liquid cooling handles the CPU thermal load inside a CoolerMaster HAF 500 chassis. A 1200W 80 PLUS Gold power supply feeds the components.

Target audience and limits

This workstation suits professionals who need high single-thread frequency, large video memory and multi-terabyte local storage for modelling, rendering or AI training workloads. Buyers who want more storage bays than the four internal drive slots provided should look at a different chassis. Systems without liquid cooling or with smaller power supplies will not match this thermal and electrical headroom.

Deciding specification

The 32GB frame buffer on the GeForce RTX 5090 is the single figure that determines whether this build fits a workload. Projects that exceed that VRAM capacity will swap to system memory and lose performance, while smaller datasets gain no extra benefit from the larger card.

Questions about this item

How loud does the 240 mm liquid cooler and the 140 mm PSU fan run when the Ryzen 9 9900X3D is under load all day?

The 240 mm Quiet Edition AIO and the Thermaltake 1200 W PSU both use ultra-quiet fans designed for low noise even during sustained workloads.

Which display cables do I need to have ready for the RTX 5090 32 GB card?

The RTX 5090 uses a PCI Express x16 slot and standard DisplayPort or HDMI outputs, so have the matching cables for your monitor on hand.

Will my existing SATA SSDs and 3.5-inch hard drives fit inside the CoolerMaster HAF 500 case?

Yes, the case provides two internal 3.5-inch bays and two 2.5-inch bays plus four SATA 6 Gb/s ports on the motherboard.
