Built for heavy creative workloads

This desktop pairs a 20-core Intel Core Ultra 7 265K with 128GB of DDR5 memory and an Nvidia GeForce RTX 5070 graphics card. It is aimed at professionals who run rendering, modelling or AI learning tasks alongside gaming. The Z890 TUF motherboard and liquid cooling keep the platform stable during sustained loads. Windows 11 Pro is installed and ready to use.

Storage capacity and headroom

A 4TB Samsung 990 PRO NVMe drive delivers read speeds up to 7450 MB/sec and write speeds up to 6900 MB/sec, providing ample space for large project files and fast asset streaming. The board includes four M.2 connectors and four SATA ports for future expansion. Memory can be increased to 192 GB across four slots if workloads grow beyond the current 128GB configuration.

Upgrade path and when it matters

The system replaces older workstations that lack DDR5 bandwidth, PCIe 4.0 storage throughput or a modern 12GB GPU for hardware-accelerated creative apps. Builders who need more than 12GB of video memory or who require ECC memory support should look elsewhere. The 750W 80 PLUS Bronze power supply supports the current specification but leaves limited headroom for significantly higher-wattage graphics cards.

Questions about this item

Will the 128GB DDR5 memory work with the four total slots on the Z890 TUF motherboard?

Yes, the 128GB DDR5 kit fills all four slots on the Z890 TUF board, which supports up to 192GB maximum capacity.

How can I verify the Samsung 990 PRO 4TB NVMe drive is delivering its rated 7450 MB/s read and 6900 MB/s write speeds after setup?

Run a benchmark such as CrystalDiskMark; sequential results should approach 7450 MB/s read and 6900 MB/s write on the PCIe 4.0x4 interface.

Does the Antec P20 case include the 3 x 120mm front fans and dust filters, or must I buy them separately?

The case ships with three 120mm front fans and bottom, front and top dust filters already installed.
