A 20-core Intel Core Ultra 7 desktop with liquid cooling, 32 GB DDR5, 4 TB NVMe and 10 TB HDD for AI-ready work and gaming
This desktop PC ships new with a 20-core Intel Core Ultra 7 265K processor and a 240 mm liquid cooler in a mid-tower case. It includes 32 GB of DDR5 memory, a 4 TB NVMe SSD and a 10 TB hard drive. The system targets professionals who need high multi-threaded throughput and large local storage without a discrete graphics card.
Video output relies on the processor’s integrated graphics providing HDMI and DisplayPort connections. This configuration handles office productivity, multi-monitor desk work and media playback but cannot accelerate modern 3D games or GPU compute workloads. Buyers who need hardware ray tracing, high-frame-rate gaming or dedicated video encoding should plan for a separate graphics card upgrade.
The motherboard uses an LGA 1851 socket on the Z890 chipset with four DDR5 slots supporting up to 192 GB total memory. Verify that your intended CPU cooler clearance fits the 240 mm radiator and that the 750 W power supply covers any future graphics card you may add. The case accepts E-ATX boards and offers front-panel USB 3.2 Gen 2 Type-C plus rear Thunderbolt 4 connectivity.

Use the 4TB Samsung 990 PRO NVMe drive for the operating system, applications and active projects — its PCIe 4.0 interface delivers up to 7450 MB/s reads and 6900 MB/s writes. Keep the 10TB hard drive with 256MB cache for bulk archives, media libraries and backups where capacity matters more than speed.
The processor runs at a 3.9 GHz base and can boost to 5.50 GHz across its 20 cores with 30 MB of L3 cache, so multi-threaded tasks such as video encoding, compilation or AI inference scale across all threads while single-thread responsiveness stays high for gaming and desktop snappiness.
The rear Thunderbolt 4 Type-C connector provides 40 Gbps bandwidth for external NVMe enclosures, docks or displays, while the additional 20 Gbps and 10 Gbps USB ports handle high-speed peripherals; Wi-Fi 7 and 2.5 Gb Ethernet give wireless and wired network headroom.
