Core Ultra 7 265K Workstation

This desktop pairs a 20-core Intel Core Ultra 7 265K processor with an Nvidia GeForce RTX 5090 graphics card. It targets professionals who need high core counts for rendering, modelling and AI learning workloads. The system ships with Windows 11 Pro and 128GB of DDR5 memory for immediate deployment.

Liquid Cooling and 1000W Gold PSU

A 240mm quiet-edition liquid cooler handles the CPU while a Thermaltake Toughpower 1000W 80 PLUS Gold supply delivers power. The Cooler Master HAF 500 case uses two 200mm front fans, a 120mm rear fan and a 120mm GPU fan for airflow. The PSU includes a 140mm ultra-quiet fan and Japanese main capacitors.

Sustained Load Behaviour

Under continuous compute or rendering tasks the liquid cooler maintains stable CPU temperatures while the case fans manage chassis heat. The 1000W Gold-rated unit provides headroom for the RTX 5090 and 20-core CPU drawing power simultaneously. The Z890 TUF motherboard and DDR5 memory sustain throughput without throttling during extended sessions.

Questions about this item

How do I install the 240mm liquid CPU cooler and which step do people miss?

The 240mm AIO Quiet Edition cooler is pre-installed on the Core Ultra 7 265K; the step people miss is connecting the pump header and ARGB cable to the Z890 TUF motherboard before first boot.

What maintenance or replacement will the 128GB DDR5 memory need later?

The 128GB DDR5 fills all four slots; future capacity increases require replacing modules with higher-density DDR5 kits up to the 192GB maximum supported by the Z890 chipset.

What limit appears first during sustained loads on the RTX 5090 32GB?

The 1000W 80 PLUS Gold PSU and 240mm liquid cooler set the practical power and thermal ceiling for the RTX 5090 32GB under continuous rendering or AI workloads.
