The Cougar GR 1000 power supply is a value-oriented 1000W unit with an MSRP of $129, designed to offer a compelling balance of features and affordability for budget-conscious PC builders. It is an 80 Plus Gold-certified unit built around the latest ATX 3.1 specification and features a fully modular cable design, support for PCIe 5.1, 100% Japanese capacitors, and a native 12V-2×6 connector that is ready for the latest Nvidia GeForce RTX graphics cards. These specifications are complemented by a 10-year warranty, which is a significant selling point that provides long-term peace of mind and sets it apart from some competitors with shorter coverage periods.
In terms of design and practicality, the GR 1000 keeps things straightforward with a no-frills aesthetic, forgoing RGB lighting in favor of a clean, professional look. Its compact 150mm chassis ensures wide compatibility with most ATX cases. The fully modular design is paired with embossed flat black cables that mimic the look of individually sleeved cables, aiding in cable management and creating a cleaner system build. Cougar has also made thoughtful refinements compared to its higher-end GLE series, such as improving the orientation of the modular connectors to make the release clips easier to access. However, the unit lacks a dedicated semi-passive or zero RPM fan mode, meaning the 140mm fluid dynamic bearing fan operates with a fixed active profile at all times.
Performance-wise, the Cougar GR 1000 proved to be a capable and reliable unit during testing. Under a maximum system load of approximately 811W, it delivered consistently stable voltages across all monitored rails, with every reading remaining comfortably within the ATX specification. While the EPS rails exhibited a slight voltage sag under heavy CPU workloads, the deviation was minimal, measuring just 0.31%, and had no practical impact on system stability. The native 12V-2×6 connector showed excellent regulation with less than 0.6% variance, and the +5V and +3.3V rails also performed well within acceptable limits. Although its voltage regulation is not quite as refined as the more premium GLE 1000, the GR 1000’s performance is excellent for its price class and more than sufficient for powering modern high-performance systems.
In conclusion, the Cougar GR 1000 offers exceptional value for builders seeking a high-capacity power supply without paying a premium. It delivers the essential features enthusiasts look for, including a fully modular design, native 12V-2×6 support, all-Japanese capacitors, and a standout 10-year warranty, all at a competitive $129 price point. While it faces competition from units like the SAMA G1000 at a slightly lower price, Cougar’s longer warranty gives it a clear advantage in long-term value. The review notes that availability is currently stronger in the Asia-Pacific region than in North America or Europe, but it is considered an easy recommendation for budget-conscious builders worldwide.
