Core Ultra 7 265K workstation

This business desktop pairs a 20-core Intel Core Ultra 7 265K processor with 128GB of DDR5 memory and an Nvidia RTX PRO 4500 Blackwell graphics card. The system targets professionals running SolidWorks CAD modelling and AI workloads that benefit from high thread counts and 32GB of GPU memory. Windows 11 Pro 64-bit is pre-installed.

4TB Samsung 990 PRO plus 10TB HDD

The primary M.2 SSD delivers read speeds up to 7450 MB/s and write speeds up to 6900 MB/s over a PCIe 4.0 x4 link, while the secondary 10TB hard drive adds 256MB of cache for bulk storage. Together they give fast project loading and large archival capacity without extra drives. The motherboard provides four M.2 connectors and four SATA 6Gb/s ports for further expansion.

PCIe 4.0 x4 and 2.5G Ethernet limits

The NVMe SSD uses a PCI Express 4.0 x4 interface, so its peak throughput is bound by that generation's lane bandwidth. Network connectivity tops out at 2.5Gbps over the Intel Ethernet controller, while Wi-Fi 7 and Bluetooth 5.4 handle wireless links. The 850W 80 PLUS Bronze power supply caps total system draw, and the LGA 1851 socket limits CPU upgrades to compatible generations.

Questions about this item

How long will the 240 mm AIO liquid cooler last before the pump or coolant needs service?

The 240 mm AIO is a sealed unit with no user-serviceable parts; pump life is typically several years of continuous operation, and the system has no provision for coolant replacement.

Which component hits its thermal or power ceiling first when the 20-core Core Ultra 7 265K and RTX PRO 4500 run flat-out?

The 850 W 80 PLUS Bronze PSU sets the overall power ceiling; sustained full-load draw from the CPU (up to 5.50 GHz) and 32 GB GPU will approach this limit before either chip hits its own thermal throttle point.

How loud does the 140 mm PSU fan and 240 mm AIO radiator get during an all-day render?

The PSU uses a 140 mm low-noise fan and the AIO is a Quiet Edition design; both are rated for ultra-quiet operation, so acoustic output stays low even under prolonged heavy load.
