Power Supply COUGAR GR 1000W ATX3.1 PCIE 5.1 80 PLUS Gold, 1000 W, 20+4 pin ATX, 120 mm fan

POWER YOU RELY ON
The COUGAR GR 1000 series is an 80 PLUS Gold-certified power supply, delivering reliable performance even at 40°C. Designed with a native PCIe 12V-2X6 connector, it meets Intel ATX 3.1 and PCIe 5.1 standards. As a modular PSU, it efficiently supports next-gen GPUs with a single 12+4-pin cable, reaching up to 91% efficiency. This reduces energy consumption, lowers electricity costs, and ensures stable power delivery.

ATX 3.1 Certified
Designed to support next-generation systems, the COUGAR GR 1000 series conforms to the ATX 3.1 standard. Featuring a native 12V-2X6 design, it provides power to the next-generation graphics cards through a single 12+4-pin cable. With an 80 PLUS Gold efficiency rating, it offers high-quality stability, durability, and reliability.

The COUGAR GR 1000 series passes the four strict power excursion tests from PSU ATX 3.1 Guide, in which the spike power consumption must bear up to 200% of the rated power for 100μs.

Designed for the Next Generation of GPUs
The COUGAR GR 1000 series supports the latest PCIe 5.1 specification: its powerful and stable performance meets the needs of next-generation GPUs, delivering perfect power for next-gen graphics cards. Equipped with a modular native PCIe 12V-2X6 connector, the 600mm length provides sufficient slack to reduce the risk of faulty connection during PC installation, without the need for a 6+2 pin adaptor.

High Performance
Efficiency
The GR 1000 series features a highly efficient design that surpasses the 80 PLUS Gold standard, to help you save money on your electricity bill.

Perfect Fan Speed to Noise Ratio
The 140mm FDB fan perfectly balances fan speed and silent performance.

FDB Fan
Compared to other fan bearing types, the FDB fan is considered the best in its class for operating noise and expected lifespan. Fluid dynamics and fluid-based characteristics greatly reduce friction and vibration, resulting in better reliability and quieter operation.

Refined Regulation. Stable Operation

How to use

Install the power supply into a compatible ATX case and connect the 20+4 pin ATX cable to the motherboard. Use the included modular cables to connect storage devices, fans and other peripherals as needed. For modern PCIe 5.1 graphics cards, connect the native 12V-2X6 (12+4 pin) cable directly to the GPU according to the GPU manufacturer’s guidance. Ensure correct cable routing to maintain airflow and avoid pinching cables. Confirm input voltage and switch off power before connecting or disconnecting components.

Recommendations

For reliable long-term operation, combine the COUGAR GR 1000 with a case that offers good airflow, connect only the required modular cables to reduce clutter, and allow some power headroom above your estimated system draw to accommodate power spikes and future upgrades.
