Fasgear PCI-e 5.0 12VHPWR vs be quiet! System Power 11 750W Power Supply

Overview of the Products

When comparing the Fasgear PCI-e 5.0 12VHPWR and the be quiet! System Power 11 750W Power Supply, it's clear each product caters to different needs within the power supply category. The Fasgear is designed primarily as an extension cable for high-performance GPUs, while the be quiet! System Power 11 is a fully-fledged power supply unit. The Fasgear is priced at £18.00, making it an affordable option for extending GPU connections, whereas the be quiet! comes in at £64.99, offering a more comprehensive power solution for demanding systems.

Design and Build Quality

The design of the Fasgear PCI-e 5.0 12VHPWR focuses on functionality and aesthetics. It features a 30cm length, allowing for better cable management in a DIY computer setup. The use of 16AWG tinned copper wire enhances current stability, which is critical for high-performance GPUs. On the other hand, the be quiet! System Power 11 750W Power Supply is built with a temperature-controlled 120mm fan that ensures quiet operation, a hallmark of the be quiet! brand. Its robust construction supports power excursions up to double its rated capacity, showcasing its ability to handle demanding conditions.

Performance and Output

The Fasgear PCI-e 5.0 extension cable supports up to 600W output, making it suitable for high-end GPUs like the RTX 4070, 4080, and 4090. This capability is essential for maintaining stable performance during heavy loads. In contrast, the be quiet! System Power 11 750W offers a maximum output of 750W, making it an ideal choice for systems requiring substantial power, including multiple GPUs or high-performance CPUs. Its 80 PLUS Bronze certification, with efficiency ratings up to 90.0%, underscores its performance and energy-saving capabilities.

Compatibility

The Fasgear PCI-e 5.0 extension cable is designed specifically for next-generation GPUs, including the RTX 3090ti and the 4000 series. It requires two unoccupied 8-pin PCI-e ports on the power supply to function correctly, ensuring compatibility with modern graphics cards. Meanwhile, the be quiet! System Power 11 750W is designed with both native integration of the 12V-2x6 connector for PCIe 5.1 graphics cards and traditional PCIe 6+2-pin connectors. This versatility makes it compatible with a broader range of components, including both current and future-generation GPUs.

Noise Levels

When it comes to noise levels, the Fasgear PCI-e 5.0 extension cable operates silently as it is a passive component. However, the be quiet! System Power 11 750W is engineered for low-noise operation, featuring a quality fan that helps keep the system quiet even under load. Users can expect remarkable quietness at this price level, making it suitable for builds where noise is a concern, such as gaming or media PCs.

Safety Features

Safety is paramount in power supplies, and both products offer different protections. The Fasgear PCI-e 5.0 extension cable includes notes about proper connection to prevent system damage but lacks integrated safety features. In contrast, the be quiet! System Power 11 750W comes equipped with multiple safety protections, including safeguards against overcurrents, over- and undervoltages, overtemperature, short circuits, and overloads. This comprehensive protection ensures that users can rely on the stability and safety of their components during operation.

Price Comparison

The Fasgear PCI-e 5.0 12VHPWR is priced at £18.00, making it a budget-friendly option for those looking to extend their GPU connections without breaking the bank. In contrast, the be quiet! System Power 11 750W is more expensive at £64.99, reflecting its advanced features and capabilities as a complete power supply solution. While the Fasgear serves a specific function, the higher price of the be quiet! can be justified by its efficiency, power output, and safety features.

Which should you buy?

Choosing between the Fasgear PCI-e 5.0 12VHPWR and the be quiet! System Power 11 750W depends largely on your needs. If you're looking for a reliable extension cable for a high-performance GPU, the Fasgear is an excellent choice at £18.00. However, for those needing a robust power supply that supports high wattage, efficiency, and safety features, the be quiet! System Power 11 at £64.99 is the superior option. Ultimately, your decision should align with your specific performance requirements and budget constraints.
