Built for heavy multitasking

This desktop pairs a 14-core Intel Core Ultra 5 245K processor with 128GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe drive. A 240mm liquid cooler keeps the CPU stable under sustained loads. The GeForce RTX 5070 12GB GPU handles modern games and GPU-accelerated creative workloads. Windows 11 Pro is pre-installed on the Z890 TUF motherboard platform.

Suits creators and power users

Video editors, 3D artists and developers who need large memory capacity and fast storage in a single workstation will benefit. The four memory slots are fully populated at 128GB, so anyone planning to expand beyond 192GB should look elsewhere. Buyers who only need mainstream gaming performance or a smaller storage footprint can save money with a lighter configuration.

Accessories expand connectivity

The Antec P20 case front panel adds two USB 3.0 ports, one USB 3.2 Gen 2 Type-C port and dual audio jacks for quick peripheral access. The motherboard rear I/O provides Thunderbolt 4, USB 20Gbps and 10Gbps Type-C ports plus 2.5Gb Ethernet. Internal headers include an extra USB 20Gbps Type-C and four SATA ports for additional drives. Wi-Fi 7 and Bluetooth 5.4 are integrated on the board.

Questions about this item

What monitor connections do I need for the RTX 5070?

The RTX 5070 provides DisplayPort and HDMI outputs. Use a cable that matches your monitor's input — DisplayPort for high refresh rates or HDMI for broad compatibility.

Will my existing SATA SSDs and hard drives work with the Z890 motherboard?

Yes. The motherboard includes four SATA 6Gb/s ports, so any 2.5-inch or 3.5-inch SATA drive can be connected directly.

How can I verify the liquid cooler is running after I power on?

In the BIOS or Windows you should see the CPU fan speed reported and the pump RPM above zero. The front-panel 120 mm fans will also be spinning and the CPU temperature should stay low at idle.
