Workstation desktop for AI and rendering

This tower system combines a 24-core Intel Core i9-14900K processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. It ships with Windows 11 Pro and a 360mm liquid cooler for sustained heavy workloads. The chassis is a CoolerMaster HAF 500 with ARGB fans and tempered glass panels.

1TB NVMe plus 10TB HDD storage

The boot drive is a Samsung 990 PRO delivering up to 7450 MB/s read and 6900 MB/s write over PCIe 4.0. A 10TB hard drive with 256MB cache adds deep capacity for project libraries and archives. Four M.2 slots and six SATA ports remain available on the Z790 AORUS motherboard for future expansion.

RTX 5090 with 32GB video memory

The graphics card provides 32GB of frame buffer, which is the decisive figure for large-model AI training, high-resolution 3D rendering and multi-monitor simulation workloads. Buyers whose projects fit within smaller VRAM allocations will not utilise this capacity.

Questions about this item

Will my older SATA 6Gb/s hard drives and USB 3.2 Gen 1 peripherals work with this Z790 motherboard?

Yes. The board provides six SATA 6Gb/s ports and rear USB 3.2 Gen 1 ports so existing drives, keyboards and mice connect without adapters.

How can I verify the i9-14900K is reaching its 6.00 GHz boost and the RTX 5090 32GB is recognised after first boot?

Open Task Manager or CPU-Z to confirm the CPU hits 6.00 GHz under load, and check Device Manager or the NVIDIA control panel to see the RTX 5090 32GB listed as the active GPU.

What storage and cooling hardware ships inside the HAF 500 case, and what must I add for a second NVMe drive?

The build includes a 1TB Samsung 990 PRO NVMe SSD, a 10TB 256MB cache HDD and a 360mm liquid CPU cooler; a second NVMe drive and its heatsink are not supplied.
