Know before you buy
These standards ensure the power supply is fully compatible with the latest high-performance graphics cards, specifically those requiring the native 12V-2x6 connector. It provides safer, more reliable power delivery for modern hardware compared to older ATX standards.
The Zero RPM mode allows the 140mm fan to remain completely stationary during low to medium loads, ensuring silent operation. The fan will only spin up automatically when the system temperature or power draw increases.
Yes, it is fully modular, meaning every cable can be detached from the power supply unit. This allows you to use only the cables your system requires, which significantly reduces clutter and improves airflow inside your PC case.
These high-quality capacitors are rated for extreme temperatures, which enhances the overall longevity and stability of the power supply. They are a hallmark of reliable units designed to handle demanding system loads over many years.
Yes, this model includes a manual fan speed control knob, giving you direct control over the cooling performance. This is particularly useful if you prefer to prioritize lower noise levels or maximum airflow based on your specific build requirements.
A 750W capacity is generally sufficient for most modern single-GPU gaming systems. However, you should check the recommended power requirements for your specific CPU and graphics card to ensure you have enough headroom for peak power spikes.
