Built for AI-ready workstations

This desktop combines a 14-core Intel Core Ultra 5 245K processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. It ships with Windows 11 Pro on an 8TB NVMe array built from two 4TB Samsung 990 PRO drives. The system targets professionals who need large memory capacity and GPU compute in a single chassis.

240mm liquid cooler and four 140mm case fans

The CPU uses a 240mm Quiet Edition AIO while the Ceres 300 case moves air through two front and one rear 140mm fans rated at 1500rpm and 30dBA each. A Thermaltake Toughpower 1000W 80 PLUS Gold unit with Japanese main capacitors delivers power with over-voltage, under-voltage, over-power and short-circuit protection.

Z890 TUF motherboard offers Thunderbolt 4

Rear I/O includes one Thunderbolt 4 Type-C, one USB 20Gbps Type-C, three USB 10Gbps and three USB 5Gbps ports alongside Intel 2.5Gb Ethernet. Internal headers add a USB 20Gbps Type-C, a USB 5Gbps and two USB 2.0 connections. Four M.2 slots and four SATA 6Gb/s ports remain available for storage expansion. Buyers who need more than 192GB of memory or a second graphics card cannot be accommodated by this platform.

Questions about this item

How do I install the 240 mm liquid cooler and what step is often missed?

Mount the 240 mm radiator to the case using the included brackets, then connect the pump header to the CPU_FAN connector on the Z890 motherboard; the step most people forget is plugging in the pump power cable so the coolant actually circulates.

Which components will need replacement first during the life of this PC?

The 140 mm case fans rated at 1500 rpm and 30 dBA are the primary moving parts that wear out; the AIO pump may also require service after several years of continuous operation.

What thermal or power limit appears first when the system runs at full load for extended periods?

The 1000 W 80 PLUS Gold power supply sets the hard ceiling; sustained combined CPU and GPU draw can approach this limit before the 240 mm liquid cooler reaches its heat‑dissipation capacity.
