Adamant Custom i9-14900K Workstation

This desktop combines a 24-core Intel Core i9-14900K processor with 64GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card carrying 32GB of video memory. It targets professionals who need high single-thread speed and massive parallel throughput for rendering, modelling and AI learning workloads. The system ships with Windows 11 Pro installed and a 4TB Samsung 990 PRO NVMe drive for fast project storage.

Z790 Platform and Connectivity Limits

The Gigabyte Z790 AORUS motherboard provides four M.2 slots and six SATA 6Gb/s ports, allowing additional NVMe or SATA drives up to the board's 192GB maximum memory capacity across four DDR5 slots. Rear I/O includes one USB Type-C, two USB 3.2 Gen 2, three USB 3.2 Gen 1 and four USB 2.0 ports, while front-panel I/O adds two USB 3.2 Gen 1, one USB 3.2 Gen 2 Type-C and audio. Networking uses Intel 2.5Gb Ethernet alongside Wi-Fi 6 and BLUETOOTH 5.2; no faster wired or wireless standards are present.

Mid-Tower Build with Liquid Cooling

The CoolerMaster HAF 500 mid-tower case measures 508 x 203 x 508 mm and includes two 200mm ARGB front fans, one 120mm ARGB rear fan and a dedicated 120mm GPU fan alongside a 360mm AIO liquid cooler for the CPU. Internal bays accept two 3.5-inch and two 2.5-inch drives, but the 5090's length and the radiator placement restrict further full-length card upgrades. The 1200W 80 PLUS Gold power supply delivers ample headroom, yet builders adding multiple high-wattage peripherals should verify total draw against the unit's 1200W rating.

Questions about this item

Should I choose the 64GB DDR5 configuration or upgrade to the maximum 192GB supported by the motherboard?

The system ships with 64GB of DDR5 installed across four slots. The Z790 AORUS board supports up to 192GB total, so you can add modules later if your rendering or AI workloads need more capacity.

What does the 6.00 GHz boost clock on the i9-14900K mean for actual editing and rendering performance?

The 24-core processor can reach 6.00 GHz on its performance cores under thermal headroom provided by the 360mm liquid cooler, shortening single-threaded compile steps and improving viewport responsiveness in modelling applications.

How fast is the Samsung 990 PRO 4TB drive on the PCIe 4.0 x4 interface in real use?

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