Built for Modelling and AI Learning

This desktop pairs an eight-core AMD Ryzen 7 9800X3D processor running at 4.7 GHz with an Nvidia GeForce RTX 5090 graphics card carrying 32 GB of video memory. Sixty-four gigabytes of DDR5 system memory and a 4 TB Samsung 990 PRO NVMe drive feed data to the GPU without bottleneck. Windows 11 Pro is pre-installed on a platform that supports up to 192 GB of RAM for future expansion.

Suits Creators Who Need Local Compute

The combination of high single-thread frequency and large VRAM makes the system viable for 3D modelling, video editing and on-premise AI training workloads. Buyers who need more storage than the 10 TB mechanical drive provides should plan additional drives. Users whose workflows rely on certified ISV drivers for specific professional applications should verify compatibility before purchase.

Accessories That Change Daily Use

A 240 mm liquid cooler keeps the CPU quiet under sustained load while the Cooler Master HAF 500 case supplies front 200 mm ARGB fans and a dedicated GPU fan for thermal headroom. The Thermaltake Toughpower 1200 W 80 PLUS Gold unit delivers stable power with Japanese capacitors. Connectivity includes dual USB4 ports at 40 Gbps, Wi-Fi 7 and Intel 2.5 Gb Ethernet for fast network transfers.

Questions about this item

Does the 1200W PSU have the 12VHPWR connector the RTX 5090 requires?

The Thermaltake Toughpower 1200W unit is specified for this build and powers the RTX 5090 32GB GPU as configured.

Will the four DDR5 slots on the TUF X870-PLUS accept my older DDR5 modules to exceed the 64GB installed?

The board has 4 total DDR5 slots supporting up to 192 GB, so additional compatible DDR5 modules can be added alongside the factory 64GB.

How can I confirm the Samsung 990 PRO is delivering its rated 7450 MB/s read speed after setup?

Run a sequential-read benchmark such as CrystalDiskMark on the 4TB NVMe drive and compare the result to the 7450 MB/s specification.
