Custom-built desktop for high-refresh gaming

This Velztorm Gemmix system pairs an 8-core Ryzen 7 5700X with a Radeon RX 6900 XT carrying 16GB GDDR6. The combination targets players who want strong 1440p frame rates and creators who need multi-threaded CPU performance in a single chassis.

Sustained load handling

A 240mm AIO liquid cooler keeps the processor near its 4.6 GHz boost during long sessions while the 750W supply feeds both components without throttling. The 64GB DDR4 buffer prevents memory pressure when games and background tasks run together.

Chassis connections and daily use

The black case measures 10.7 IN by 16.5 IN by 15 IN and weighs 32.4lb, so it sits on a desk or floor without special mounting. Rear I/O provides one HDMI, one DisplayPort, USB 3.2 Type-C Gen2, six USB 2.0 ports and a combo audio jack for headsets.

Questions about this item

How loud and warm does the 240mm AIO liquid CPU cooler keep the Ryzen 7 5700X during long sessions?

The 240mm AIO liquid CPU cooler with RGB lighting is designed to handle the 8-core processor's thermal output, maintaining lower temperatures than air coolers while the 750W power supply delivers stable power.

What display and cable do I need to use the Radeon RX 6900 XT's video outputs?

You must provide a monitor with either an HDMI or DisplayPort input and the matching cable; the system includes one HDMI port and one DisplayPort on the graphics card.

Will my older USB 2.0 peripherals work with the front and rear ports on this desktop?

Yes, the chassis provides six USB 2.0 ports alongside a USB 3.2 Type-C Gen2 port, so legacy keyboards, mice and headsets connect directly without adapters.
