PURE POWERL8 630W / CM
The Essential Power Supply Unit. For quiet and reliable operation and the best quality
When designing the Pure Power Series, our developers in Germany concentrated on the most important features applications such as reliability and secure operation.
The Pure Power L8-630W has been engineered with the same high quality that you have come to know and appreciate from be quiet!. The usual quiet operation thanks to a high-quality temperature-controlled 120mm fan and the usual stable performance thanks to two separate 12V rails.
The L8-630W offers an efficient and economical operation, achieving an 80PLUS Bronze certification with an efficiency of up to 88%.
Equipped with four PCI Express connectors (2x 6+2 pin and 2x 6 pin), the L8-630W is suitable for multi-GPU operation.
Quiet operation through be quiet! fan using SilentWings technology
- 120mm fan with flow-optimised fan blades for enhanced airflow and exceptionally quiet operation. Especially quiet thanks to optimised rotational speed throughout the working range. Quiet operation and long lifespan of up to 100,000 hours thanks to a high-quality bearing and an individually balanced fan wheel.
High performance and stability for CPU and GPU
- Two independent 12V rails. Suitable for SLI and Crossfire multi-GPU operation. Supports the latest generations of processors from Intel® and AMD.
Efficient and economical operation
- 80PLUS bronze certification for top efficiency of up to 88%. ErP ready. Stand-by energy consumption 0.3W.
Very high compatibility with older and future components
