Intel Core Ultra 7 265K desktop

This Adamant Custom system pairs a 20-core Intel Core Ultra 7 265K processor with 128GB of DDR5 memory and a GeForce RTX 5080 graphics card. A 4TB Samsung 990 PRO NVMe drive provides primary storage. Liquid cooling and a 1000W 80 PLUS Gold power supply support sustained workloads. Windows 11 Pro is installed.

Suits rendering, modelling and AI learning

The 20-core CPU and 128GB RAM suit professionals running heavy rendering, modelling or AI learning tasks. Buyers who need more than 4TB of fast storage should look elsewhere. The configuration includes no hard drive bays for bulk archival drives. Maximum memory supported is 192GB.

4TB Samsung 990 PRO NVMe SSD

The boot and application drive is a 4TB Samsung 990 PRO PCIe 4.0x4 NVMe SSD. Sequential reads reach up to 7450 MB/sec and writes up to 6900 MB/sec. This single specification determines whether capacity and speed meet project demands.

Questions about this item

How loud and hot does the 240mm liquid cooler keep the 20-core Core Ultra 7 265K under all-day load?

The 240mm Quiet Edition AIO uses a 140mm low-noise fan and liquid cooling to manage the 20-core CPU at 3.7GHz base, up to 5.50GHz boost, with a 1000W 80 PLUS Gold PSU supplying efficient power.

What display cable and monitor port do I need for the RTX 5080 16GB to work out of the box?

The RTX 5080 16GB uses standard DisplayPort and HDMI outputs; connect a compatible monitor cable to one of those ports — no proprietary adapter is included.

Will my existing SATA SSDs and 2.5-inch drives fit inside the Antec P20 case alongside the 4TB NVMe boot drive?

Yes — the case provides two internal 3.5"/2.5" bays and two dedicated 2.5" bays, plus four SATA 6Gb/s ports on the Z890 motherboard for additional drives.
