Power Supply COUGAR GR 1000, 1000W 80 Plus Gold ATX 3.1 PSU - CGR GDN-1000

Cougar GR 1000 is a 1000W ATX power supply aimed at more serious gaming and workstation configurations, where there is a powerful GPU and potentially a lot of storage. With an 80+ Gold certification and up to 91% efficiency, it keeps consumption and heating under control, which is important during long gaming sessions. It supports ATX 3.0/3.1 and PCIe Gen 5, so you are ready for modern graphics cards with a 12VHPWR connector. The compact length of 150 mm makes installation easier even in tighter mid-tower cases.

What you get: with real 1000W and active PFC, you have stable lines of 3.3/5/±12 V for powerful CPUs and high-end GPUs, without worrying about sudden voltage drops under load. The modular design allows you to connect only the necessary cables, improving airflow and making assembly much cleaner. With one 12+4-pin PCI-E (12VHPWR) plus additional 6+2-pin PCI-E connectors, you can comfortably power a modern graphics card, and if needed – also an older GPU in parallel. With 9 SATA and 3 Molex, you can easily build a system with multiple SSDs/HDDs, fans, and accessories. A 120 mm fan takes care of cooling, and the higher efficiency reduces heat output and noise during normal operation.

• Power 1000W – sufficient for high-end GPUs and multi-core CPUs, overclocking, and future upgrades without worrying about changing the power supply.
• 80+ Gold certification and up to 91% efficiency – less energy lost as heat and more stable operation under prolonged load.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – fully ready for modern graphics cards and standards, including high peak loads.
• 1 x 12+4-pin PCI-E (12VHPWR) + 3 x 6+2-pin PCI-E – flexibility for a powerful new generation GPU or a combination of several older cards.
• 9 x SATA and 3 x Molex connectors – allows building a system with many SSDs/HDDs, fans, and peripherals without additional splitters.
• Modular design – remove unnecessary cables, improving cable management and airflow inside the case.
• Compact dimensions 150 x 150 x 86 mm and 120 mm fan – easy installation in standard ATX cases and effective cooling.

Who it is suitable for: if you are building a serious gaming PC with a powerful GPU, streaming, and rendering, or a workstation with many drives, this 1000W ATX 3.1 power supply is a very reasonable choice. It is also suitable if you plan future upgrades to more power-efficient graphics cards. For ultra-budget office configurations, it is frankly unnecessary – there, a lower power would be more sensible.

The combination of 1000W, 80+ Gold efficiency, ATX 3.1, and modular design makes the Cougar GR 1000 a stable foundation for a long-term build, where you won’t worry about whether the power supply is “tightening” the configuration.
