CORSAIR RM650e vs Fasgear PCI-e 5.0 12VHPWR

Overview of the Products

In this comparison, we will examine the CORSAIR RM650e and the Fasgear PCI-e 5.0 12VHPWR. The CORSAIR RM650e is a high-performance power supply unit (PSU) priced at £71.57, while the Fasgear PCI-e 5.0 extension cable is significantly cheaper at £18.00. The two products cater to different needs within computer builds, with one serving as an essential PSU and the other as an extension cable designed for high-end graphics cards.

Design and Build Quality

The CORSAIR RM650e boasts a fully modular design, allowing users to connect only the necessary cables for their builds. This feature not only enhances aesthetics but also optimises airflow within the case. With a 120mm rifle-bearing fan, it ensures low noise levels, even under full load. In contrast, the Fasgear PCI-e 5.0 extension cable is constructed with 16AWG tinned copper wire, which is an upgrade from standard 18AWG cables. This design choice allows for stable and higher currents, supporting up to 600W output. While the RM650e focuses on overall power delivery, the Fasgear cable is intended to extend connectivity options for graphics cards.

Performance

When it comes to performance, the CORSAIR RM650e excels with its Intel ATX 3.1 certification. This certification ensures that it can handle PCIe 5.1 platforms and withstands 2x transient power excursions, making it a reliable choice for high-performance builds. The RM650e is designed to deliver steady and reliable power with 105°C-rated capacitors, ensuring long-lasting performance. The Fasgear PCI-e 5.0 extension cable, while less powerful, is tailored for specific graphics cards, including the RTX 3090ti and the 4000 series, making it a great addition for users who require longer cable lengths without compromising on performance.

Compatibility

The CORSAIR RM650e is compatible with a wide range of systems due to its fully modular design and compliance with the latest power standards. It offers a robust solution for those looking to build or upgrade their systems. On the other hand, the Fasgear PCI-e 5.0 extension cable is specifically designed for use with the latest NVIDIA graphics cards, such as the RTX 4070, 4080, and 4090. While it supports a broad range of GPUs, it is essential for users to verify their specific requirements regarding cable compatibility and PSU capacity.

Price and Value

At £71.57, the CORSAIR RM650e represents a significant investment but offers features and reliability that justify the price. Its performance and modularity cater to enthusiasts and professionals who demand high-quality components in their builds. In stark contrast, the Fasgear PCI-e 5.0 extension cable is priced at £18.00, making it an affordable option for users who need to extend their GPU connections without the need to replace their entire PSU. In terms of value, the RM650e is geared towards those seeking a premium PSU, while the Fasgear cable serves as a budget-friendly accessory.

Noise Levels

The CORSAIR RM650e is designed to operate quietly, thanks to its 120mm rifle-bearing fan that maintains low noise levels, even under full load. This feature is particularly beneficial for users who prioritise a quiet computing environment. In comparison, the Fasgear PCI-e 5.0 extension cable does not have any noise output as it is simply an extension that carries power. Therefore, if noise levels are a key consideration in your build, the RM650e clearly stands out as the quieter option.

Installation and Use

Installing the CORSAIR RM650e is straightforward due to its fully modular design, which allows users to connect only the cables needed for their specific setup. This feature not only simplifies installation but also aids in cable management within the case. The Fasgear PCI-e 5.0 extension cable is also user-friendly, designed to connect easily to existing PSU and GPU setups. Users should ensure they have two unoccupied 8-pin PCI-e ports for proper functionality. Both products cater to users looking to enhance their systems, but the RM650e offers a more comprehensive installation experience.

Which should you buy?

Choosing between the CORSAIR RM650e and the Fasgear PCI-e 5.0 extension cable ultimately depends on your specific needs. If you're in the market for a high-quality, reliable power supply that supports modern hardware and offers a quiet operation, the CORSAIR RM650e is the clear winner. However, if you are looking to extend the reach of your GPU's power connection affordably, the Fasgear PCI-e 5.0 extension cable provides excellent value. For a complete build, the RM650e is essential, while the Fasgear cable serves as a practical addition for specific scenarios.
