Users frequently highlight its robust build and stable power delivery, ensuring peace of mind for demanding systems. The fully modular design also contributes to an easy and clean installation experience.

Know before you buy
Yes. Because it is ATX 3.1 and PCIe 5.1 compliant, it includes the native 12+4-pin connector required for modern high-performance GPUs, ensuring stable power delivery without the need for bulky adapters.
A fully modular design means every cable can be detached from the power supply unit. This allows you to use only the cables your specific components require, which significantly reduces cable clutter and improves airflow inside your case.
The unit uses a 140mm Fluid Dynamic Bearing fan, which is designed for longevity and low-noise operation. It remains quiet even under load, making it a great choice for builders who prioritize a silent workspace.
The Leadex III features a comprehensive suite of safety protections, including OVP (Over Voltage), OCP (Over Current), OPP (Over Power), SCP (Short Circuit), UVP (Under Voltage), OTP (Over Temperature), NLO (No Load Operation), and SIP (Surge and Inrush Protection) to keep your hardware safe from electrical anomalies.
1000 watts is more than sufficient for most high-end gaming rigs, including those with top-tier CPUs and GPUs. It provides plenty of headroom for future upgrades and ensures the power supply operates efficiently without being pushed to its limits.
Super Flower provides a 10-year limited warranty covering both parts and labor. This long-term coverage reflects the build quality and provides peace of mind for the lifespan of your PC build.
