Built for 4K gaming and heavy workloads

This Skytech Legacy 4 desktop pairs an AMD Ryzen 9 9950X3D processor with an NVIDIA RTX 5090 graphics card carrying 32 GB of GDDR7 memory. The CPU runs at a 4.3 GHz base clock and can boost to 5.7 GHz. Windows 11 Home is pre-installed on a 4 TB NVMe SSD, and 64 GB of DDR5 6000 memory handles multitasking and content creation.

Ready to run with 1200W ATX 3.0 power

A 1200W Gold-rated ATX 3.0 power supply feeds the CPU and GPU without extra cables or adapters. The 360mm AIO cooler with ARGB fans keeps the 9950X3D at operating temperature under sustained load. An X870 motherboard provides the platform, while 802.11 AC Wi-Fi handles wireless networking. No mechanical drive is included, so the NVMe SSD is the sole storage device.

Replaces a custom high-end build when assembly

This system substitutes a self-assembled Ryzen 9000-series and RTX 5090 rig for buyers who want the same specifications without sourcing parts or managing cable routing. The jump is worth it when a single warranty and validated hardware compatibility outweigh the flexibility of choosing individual components. Builders who need additional drive bays, a different cooling layout or a specific GPU brand should look elsewhere.

Questions about this item

How does the 360 mm AIO liquid cooler handle the Ryzen 9 9950X3D during long gaming sessions?

The 360 mm AIO liquid cooler with ARGB fans is designed to manage the thermal output of the Ryzen 9 9950X3D, which has a 4.3 GHz base and 5.7 GHz turbo frequency, keeping temperatures stable under sustained heavy loads.

What is the typical noise level from the 360 mm AIO and the 1200 W power supply when the system runs all day?

The 360 mm AIO uses ARGB fans that adjust speed based on CPU temperature, while the 1200 W Gold ATX 3.0 PSU fan runs quietly at low loads, so noise stays low during typical all-day use and only rises under maximum GPU and CPU stress.

Does the X870 motherboard include Wi-Fi, or do I need a separate wireless adapter?

The motherboard provides 802.11 AC Wi-Fi built in, so no separate wireless adapter is required for network connectivity.
