High-performance desktop for gaming and creation

The Skytech Legacy ST-LEGACY4-1805-B-AL is a new gaming desktop PC built around an AMD Ryzen 7 7800X3D processor with a 4.2GHz base clock and 5.0GHz turbo boost, paired with an NVIDIA RTX 5090 graphics card carrying 32GB GDDR7 memory, 64GB DDR5 6000 RAM and a 2TB NVMe SSD.

Suitable for high-refresh 4K gaming

This system suits players who want maximum frame rates at 4K resolution and creators who need 32GB of video memory for rendering or AI tasks; it is not for buyers who need more than 2TB of fast storage or who require multiple graphics cards.

Graphics card with 32GB GDDR7 video memory

The single specification that decides fit is the RTX 5090 equipped with 32GB GDDR7, which determines whether the machine can hold the textures, models or datasets your workflow demands.

商品問答

How loud does the 360 mm AIO liquid cooler run when the Ryzen 7 7800X3D sustains its 5.0 GHz boost all day?

The 360 mm AIO liquid cooler is designed to keep the Ryzen 7 7800X3D within thermal limits during sustained 5.0 GHz boost operation, minimising fan noise while preventing thermal throttling.

Does the motherboard provide the 12VHPWR connector required by the RTX 5090 32 GB GDDR7, or must I supply an adapter?

The 1000 W power supply includes native 12VHPWR cabling for the RTX 5090 32 GB GDDR7, so no adapter is needed.

Can I keep using my current 1080p 60 Hz monitor with the single HDMI and single DisplayPort outputs on the RTX 5090?

Yes, the RTX 5090 provides one HDMI and one DisplayPort output, both compatible with a 1080p 60 Hz monitor.
