20-Core Workstation for AI and Rendering

This desktop pairs a 20-core Intel Core Ultra 7 265K with an Nvidia GeForce RTX 5070 and 128GB of DDR5 memory. It is built for professionals who run local AI inference, 3D modelling and video editing workloads that demand both high thread counts and GPU acceleration. The 8TB of NVMe storage across two Samsung 990 PRO drives keeps large project files on fast local storage.

240mm Liquid Cooling and 750W Bronze Power

A 240mm Quiet Edition AIO handles the CPU while front and rear 140mm case fans run at 1500rpm with a listed 30dBA noise level. The Thermaltake Smart 750W 80 PLUS Bronze unit uses Japanese main capacitors and includes over-voltage, under-voltage, over-power and short-circuit protection. Liquid cooling and the high-efficiency supply keep thermals and acoustics controlled during sustained render or compute sessions.

Upgrade From 64GB Systems or SATA Storage

Builders moving from 64GB DDR5 configurations gain headroom for larger datasets and concurrent virtual machines without swapping. The jump from SATA SSDs to dual PCIe 4.0 NVMe drives delivering up to 7450 MB/s read and 6900 MB/s write cuts asset load times in heavy creative pipelines. The step is worth it when memory pressure or storage latency is the current bottleneck.

Questions about this item

How do I install the 240 mm AIO liquid cooler on the LGA 1851 socket, and which step is often missed?

Mount the supplied LGA 1851 bracket, apply thermal paste, secure the cold plate with the four captive screws in a cross pattern, then connect the pump header and both 140 mm fan headers to the Z890 TUF motherboard; the step most builders miss is plugging the pump tach cable into the dedicated AIO_PUMP header so the BIOS can monitor flow.

What maintenance or replacement will the 240 mm Quiet Edition AIO and the two 4 TB Samsung 990 PRO SSDs need later?

The sealed AIO requires no coolant refill; plan to clean the radiator fins and replace the two 140 mm radiator fans when noise rises above 30 dBA, and monitor each 990 PRO via Samsung Magician — replace a drive once its SMART wear indicator approaches the rated endurance limit.

Which limit appears first during sustained all-core workloads on the Core Ultra 7 265K with this 240 mm AIO?

The 240 mm radiator reaches thermal saturation before the CPU hits its 5.50 GHz turbo ceiling, so coolant temperature becomes the bottleneck that forces clock speeds down during prolonged rendering or AI training sessions.
