Built for AI-ready creative workloads

This desktop pairs a 14-core Intel Core Ultra 5 245K processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5070 graphics card. The system targets professionals who need fast rendering, local AI inference and responsive multitasking in a single workstation. Windows 11 Pro ships pre-installed on a 1TB Samsung 990 PRO NVMe drive.

PCIe 4.0 and 2.5 GbE set the throughput ceiling

The boot SSD reaches 7450 MB/s read and 6900 MB/s write over a PCIe 4.0 x4 link, so sustained transfers cannot exceed that bandwidth. Network traffic tops out at 2.5 Gbps on the Intel Ethernet controller, while Wi-Fi 7 and Bluetooth 5.4 share the same 2x2 radio. Four SATA 6 Gb/s ports and four M.2 slots provide expansion headroom within those limits.

Pre-assembled with a 240 mm liquid cooler

The CPU cooler, motherboard, power supply and drives arrive installed inside the Corsair 4000D case, so the builder only connects peripherals and power. A 750 W 80 Plus Bronze unit with a 140 mm fan feeds all components, and the board uses an LGA 1851 socket that accepts no other processor family. Internal bays hold two 3.5-inch and two 2.5-inch drives if more storage is added later.

Questions about this item

Should I choose the 128GB DDR5 configuration or add more memory up to the 192GB maximum?

The system ships with 128GB DDR5 across four slots. The Z890 motherboard supports up to 192GB, so you can add modules later if workloads demand it.

What does the Core Ultra 5 245K's 5.20 GHz boost mean for actual gaming and rendering?

The 14-core CPU reaches 5.20 GHz on thermal headroom, so single-threaded game logic and light render bursts run at that speed while the 240mm liquid cooler keeps temperatures stable.

How fast is the Samsung 990 PRO 1TB drive on the PCIe 4.0x4 interface in daily use?

The M.2 SSD delivers up to 7450 MB/s reads and 6900 MB/s writes over four PCIe 4.0 lanes, so large project loads and game level streaming are near the interface ceiling.
