Built for AI workstations and 4K gaming

This desktop combines a 20-core Intel Core Ultra 7 265K processor with 192GB DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. It targets professionals running local AI models, complex rendering or heavy multitasking alongside high-refresh 4K gaming. The 2TB Samsung 990 PRO NVMe drive and 10TB hard drive provide fast boot and deep archive storage in one chassis.

PCIe 4.0 x4 and 2.5GbE set the throughput ceiling

The operating system and primary applications reside on a PCIe 4.0 x4 NVMe SSD rated for 7450 MB/s read and 6900 MB/s write. Wired networking tops out at 2.5Gb Ethernet, while wireless uses Wi-Fi 7 2x2. Rear I/O includes one Thunderbolt 4 Type-C port, one USB 20Gbps Type-C, three USB 10Gbps and three USB 5Gbps ports. Internal expansion offers four SATA 6Gb/s and four M.2 connectors.

192GB DDR5 is the maximum this platform supports

Four memory slots are populated to the 192GB limit, leaving no room for future RAM upgrades. Buyers who anticipate larger datasets or heavier virtualisation workloads should note that capacity cannot be increased beyond this configuration.

Questions about this item

Should I pick the 2TB NVMe or the 10TB HDD for my main workload?

Use the 2TB Samsung 990 PRO for the operating system and active projects — its 7450 MB/s read and 6900 MB/s write keep apps responsive. Keep the 10TB drive with 256 MB cache for bulk media and archives.

What does the 5.50 GHz boost clock on the 20-core Ultra 7 265K actually deliver inside this chassis?

The 240 mm liquid cooler lets the CPU sustain high frequencies during long renders or model training, so multi-threaded workloads stay near the 5.50 GHz ceiling instead of throttling.

How fast can the Thunderbolt 4 port move data with an external drive?

The rear Thunderbolt 4 Type-C port provides up to 40 Gbps bandwidth, so compatible external storage will run at its rated speed without bottlenecks.
