Power supply COUGAR GR 850W 80 Plus Gold ATX 3.1 Fully Modular PSU - CGR GDN-850

Cougar GR 850W is an 850-watt, fully modular ATX power supply aimed at mid-range to high-end gaming and workstation configurations. With 80+ Gold certification and up to 91% efficiency, you get stable power with less loss and lower heat. It features a 120 mm fan, and its length of only 140 mm makes it convenient for more compact cases. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 ensures that you are ready for current and next-generation graphics cards.

What you get: with a power of 850 W, you have enough resources for a powerful CPU and serious GPU, without the power supply gasping under peak loads. The fully modular design allows you to use only the necessary cables, which simplifies cable management and improves airflow in the case. The 12+4 pin PCI-E (PCI-E Gen5 12VHPWR) connector is key if you plan or already have a modern graphics card from the latest generations. Thanks to the active PFC and high efficiency at input voltage 100 - 240 VAC, 50/60 Hz, the power supply is stable under various electrical conditions. The compact ATX format with dimensions 140 x 150 x 86 mm makes it a flexible choice for most mid-tower and even some smaller cases.

• Power 850 W – sufficient for gaming and creative configurations with a powerful GPU and many storage devices.
• 80+ Gold certification and up to 91% efficiency – less heat loss, lower load on the electrical grid, and quieter operation under typical load.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 and 12+4 pin PCI-E (12VHPWR) – readiness for modern and future graphics cards without the need for adapters.
• Fully modular design – all cables are detachable, making assembly cleaner and easier to maintain.
• Rich set of connectors: 1 x 20+4 pin ATX, 2 x 4+4 Pin CPU, 2 x 6+2 Pin PCI-E, 6 x 15 pin SATA and 2 x 4 Pin Molex for flexible component connections.
• 120 mm fan – provides necessary cooling for the power supply at normal noise levels.
• Compact dimensions 140 x 150 x 86 mm in black – easily fits in most ATX cases and does not attract unnecessary attention visually.
• Active PFC – cleaner and more stable power to components under varying input voltages.

Who it is suitable for: this power supply is a good choice for gaming and streaming builds that plan a powerful graphics card, including PCIe Gen 5 models with 12VHPWR. It is also suitable for working with heavy applications – 3D rendering, video editing, development – where stability under load is important. If you are building a super budget office build or a small low-power system, this power supply is more of an overkill.

The combination of 850 W power, 80+ Gold efficiency, and ATX 3.1 with a 12VHPWR connector makes Cougar GR 850W a balanced, modern choice for a serious gaming or workstation computer. You get a power supply that won't limit you during your next GPU upgrade.
