Skytech O11 Vision Gaming PC

This Skytech O11 Vision desktop ships new with a Ryzen 7 7800X3D processor and a GeForce RTX 5090 graphics card. It targets gamers and creators who want high frame rates at 4K and local AI acceleration. The 64GB DDR5 6000 memory kit and 2TB NVMe SSD provide headroom for large projects. Windows 11 Home is pre-installed.

AM5 platform and PCIe Gen4 storage limits

The AM5 socket supports one processor, so CPU upgrades stay within the Ryzen 7000 series. The X670 motherboard runs the NVMe drive at PCIe Gen4 speeds; newer Gen5 drives will operate at Gen4 rates. The 1200W ATX 3.0 power supply delivers up to 600W over the 12VHPWR connector for the GPU. Wi-Fi uses 802.11 AC.

Pre-built system with 360mm AIO cooler

The PC arrives fully assembled, so installation means connecting power and peripherals. The 360mm AIO liquid cooler with ARGB fans is already mounted on the CPU. Builders who want a custom loop must disassemble the factory cooling. The O11 Vision chassis layout follows standard ATX dimensions for future part swaps.

Questions about this item

Should I choose the 32 GB GDDR7 GPU or the 64 GB DDR5 system memory for my workload?

The 32 GB GDDR7 on the RTX 5090 handles graphics and AI compute, while the 64 GB DDR5 6000 feeds the Ryzen 7 7800X3D for multitasking and large datasets; both are fixed in this build.

What does the 5.0 GHz turbo on the Ryzen 7 7800X3D deliver once the PC is assembled?

The 5.0 GHz boost clock on the 7800X3D raises single-thread speed for gaming and light loads, while the 3D V-Cache keeps frame rates high in cache-sensitive titles.

Does the X670 motherboard cap the 2 TB NVMe SSD at Gen 4 speeds?

The X670 chipset supports PCIe Gen 4 for the M.2 slot, so the 2 TB NVMe drive runs at its rated Gen 4 throughput without bottleneck.
