Know before you buy
The ATX 3.1 standard is designed to handle the high power excursions and transient spikes common in modern, high-performance GPUs. It ensures better stability and safety for your components compared to older ATX 2.x units.
Yes, the C1000 Gold includes a native 12V-2x6 connector capable of delivering up to 600W, making it fully compatible with the power requirements of RTX 50 series and other high-end GPUs.
When your system is under 50% load, the 135mm fan remains completely off, resulting in silent operation for tasks like web browsing or document editing. The fan only activates once the power draw increases, ensuring quiet performance when you need it most.
Yes, a fully modular design allows you to connect only the cables you need, which significantly reduces cable clutter in your case. This improves internal airflow and makes the initial installation process much cleaner and easier to manage.
Japanese capacitors are widely regarded for their superior heat resistance and longevity compared to standard alternatives. Using them throughout the unit ensures the power supply maintains consistent, reliable voltage delivery over many years of heavy use.
Yes, the 10-year warranty covers the entire power supply unit, including the fan and internal electronics. It provides long-term protection for your investment, reflecting the manufacturer's confidence in the build quality.
