Ready-to-Game Desktop

The PRC DEMONIO1 is a pre-built gaming desktop built around a 12-core Intel Core i7-12700K processor running at 3.6 GHz with a 5.0 GHz maximum boost. It ships with 16 GB of DDR4-3200 memory and a dual-drive layout combining a 1 TB NVMe boot drive with a 4 TB SSD for bulk storage. Windows 11 Home is installed and the system is cooled by a 280 mm ARGB liquid cooler.

Step Up From Mid-Range Builds

This configuration replaces a typical mid-range rig that relies on a 6-core CPU and an 8 GB graphics card. The jump is worth it when you want 12 CPU cores with 20 threads for streaming while gaming and need 12 GB of GDDR6X video memory for 1440p textures. The 750 W 80+ Gold modular supply delivers clean power for the whole platform without cable clutter.

Sustained Load Behaviour

Under extended sessions the 280 mm AIO keeps the 12700K at stable clocks rather than letting it throttle after a short burst. The RTX 4070 maintains its boost frequency because the fully modular gold-rated unit holds voltage steady across both 12 V rails. Airflow stays consistent thanks to the ARGB fans on the radiator and the case layout.

Questions about this item

Will the 240 mm AIO liquid cooler fit my case?

The CPU cooler is a 240 mm ARGB AIO; check that your chassis supports a 240 mm radiator and has clearance for the pump block.

What is the correct way to seat the RTX 4070 in the PCIe slot?

Remove the rear bracket covers, align the card with the top x16 slot, press firmly until the retention click engages, then connect the required 12VHPWR power cable from the 750 W supply.

When should I plan to replace the 750 W 80+ Gold power supply?

A quality 750 W Gold unit typically lasts 7–10 years; swap it if you notice random shutdowns, coil whine under load, or when upgrading to a significantly higher-wattage GPU.
