ATX 3.1 Certified

Designed to support next-generation systems, the COUGAR GR 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 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.

ATX 3.1 Criteria	Dynamic Power Excursion
100us	1500W
1ms	1350W
10ms	1200W
100ms	900W

Note: Above test results based on 850W’s performance data.

Designed for the Next Generation of GPUs

The COUGAR GR 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.

Notice: Before using the PCIe 12+4pin cable, please visit the GPU manufacturer’s official website to check recommended wattage requirements.

Protection

UVP (Under Voltage Protection)

If the voltages fall below a certain tolerance value on the single lines, the PSU automatically switches off.

OCP (Overcurrent Protection)

If the current on a single line is higher than indicated, the PSU automatically switches off.

SCP (Short-Circuit Protection)

In the case of a short-circuit, this feature prevents damage to the core components of the PSU and its System components.

OVP (Over Voltage Protection)

If the voltages increase above a certain tolerance value on the single lines, the PSU automatically switches off.

OTP (Over Temperature Protection)

If the temperature gets too high, the PSU automatically switches off.

OPP (Over Power Protection)

If the system is oversized and requires more power from the PSU than it can provide, this protection function is activated.
