Adamant Custom Core Ultra 7 265K RTX 5090 Desktop

This new gaming desktop PC pairs a 20-core Intel Core Ultra 7 265K processor with an Nvidia GeForce RTX 5090 graphics card. It includes 32GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe SSD. A 240mm liquid cooler and a 1000W 80 PLUS Gold power supply support the high-performance components inside a Corsair 4000D case. Windows 11 Pro comes pre-installed.

Who This Suits and Who Should Look Elsewhere

This system suits users who want a ready-to-use workstation for gaming and media creation with strong AI-ready hardware. The four memory slots allow expansion up to 192GB total capacity. Builders who need more storage bays than the two 3.5-inch and two 2.5-inch internal slots provide, or who prefer air cooling over liquid, should consider a different configuration.

The Spec That Decides Fit

The motherboard uses the LGA 1851 socket, which only accepts Intel Core Ultra Series 2 processors. If your upgrade path requires a different socket or chipset family, this platform will not support it. The Z890 chipset provides four M.2 connectors and Thunderbolt 4 connectivity for high-speed peripherals.

Questions about this item

How loud and hot does the 240mm liquid cooler keep the 20-core Core Ultra 7 265K and RTX 5090 under all-day load?

The 240mm Quiet Edition AIO and 140mm PSU fan are designed for low noise, while the 1000W 80 PLUS Gold supply delivers efficient power to the 20-core CPU and 32GB GPU during extended sessions.

Which display cables and monitor inputs do I need to use the RTX 5090 32GB right out of the box?

The RTX 5090 provides modern display outputs; connect a compatible monitor with the appropriate cable — HDMI or DisplayPort — to start gaming immediately.

Will my existing SATA SSDs and USB 3.2 peripherals work with the Z890 motherboard and Corsair 4000D case?

Yes — the board offers four SATA 6Gb/s ports and the case front panel includes USB 3.2 Type-C and Gen1 ports, so current drives and devices plug in directly.
