Built for rendering, editing.

This Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. A 1TB Samsung 990 PRO NVMe drive and a 10TB hard drive provide fast boot and deep archive storage. Windows 11 Pro 64-bit is pre-installed on the Z890 UD motherboard.

Practical limits of the Z890 platform

The motherboard supports four DDR5 slots with a 192GB maximum, so this build already reaches the ceiling. Wired networking tops out at 2.5Gbps through the Intel controller, while Wi-Fi 6E and Bluetooth 5.3 handle wireless links. Four M.2 connectors and four SATA 6Gb/s ports with RAID 0, 1, 5 and 10 define the internal expansion boundary.

Installation notes and common pitfalls

The system ships fully assembled in a Corsair 4000D case with a 360mm liquid cooler and a 1200W 80 PLUS Gold power supply, so no component fitting is required. Buyers who want more storage must add drives themselves using the two 3.5-inch and two 2.5-inch bays. Front-panel I/O offers one USB 3.2 Type-C and two USB 3.2 Gen 1 ports plus an audio combo jack.

Questions about this item

Should I choose the 192GB DDR5 option or look for a smaller kit for this Z890 UD build?

The board has 4 total slots and supports up to 192 GB. The 192GB kit fills every slot at the maximum supported capacity, leaving no room for later expansion but delivering the full bandwidth the CPU can use.

What does the 5.70 GHz figure mean once the Core Ultra 9 285K is inside this liquid-cooled tower?

That is the maximum turbo frequency the 24-core processor can reach on one or two cores when thermals allow. The 360 mm AIO keeps temperatures low enough to sustain high clocks longer than an air cooler would.

How does the Wi-Fi 6E AX211 and 2.5 Gbps LAN cap real-world throughput in this system?

The AX211 runs on 2.4, 5 and 6 GHz bands with Bluetooth 5.3, while the Intel 2.5 Gb Ethernet port tops out at 2.5 Gbps. Both share the Z890 chipset, so simultaneous wired and wireless traffic stays within those limits.
