## Summary description

COUGAR GR 750W is an ATX3.1 power supply unit with PCIe 5.1 support and 80 PLUS Gold efficiency (≈91%). Provides 750 W total power, 20+4 pin ATX motherboard connector, active cooling with a 120 mm fan, and universal 100–240 V AC input. Suitable for desktop PCs and gaming rigs requiring high-efficiency, stable power delivery and modern PCIe compatibility.

## Long description

The COUGAR GR 750W is an ATX 3.1-compatible power supply designed for modern desktop PCs and gaming rigs. It delivers 750 W of total power with an 80 PLUS Gold efficiency of about 91%, native support for PCIe 5.1 graphics through a modular 12V-2X6 (12+4 pin) connector, and a 20+4 pin ATX motherboard connector. The unit is compact (140 mm length), operates reliably up to 40°C, and uses a 120 mm rifle-bearing fan for balanced cooling and low noise.
Advantages
The GR series combines ATX 3.1 and PCIe 5.1 compliance with high conversion efficiency to reduce energy consumption and provide stable power delivery for next-generation GPUs. Fully modular, embossed black cables reduce clutter and improve airflow while the 105°C Japanese main capacitor and tight voltage regulation ensure consistent, durable operation. The native 12V-2X6 connector (12+4 pin) supplies dynamic spike loads according to the ATX 3.1 power excursion requirements.
Suitable for
Gaming desktops with modern PCIe 5.1 GPUs
High-performance workstations and multi-core CPU platforms
PC builds where compact PSU size (140 mm) and modular cabling are desired
When it may not be suitable
This PSU is focused on modern systems requiring PCIe 5.1 and ATX 3.1 features; it may be unnecessary for very small, low-power office PCs or legacy systems that do not need high transient power support. If your build does not use PCIe 5.1 graphics or requires less than 750 W total, a lower-capacity, lower-cost unit could be more appropriate.

How to use
Install the COUGAR GR 750W into a compatible ATX PSU bay and secure it with the case screws. Connect the 20+4 pin ATX cable to your motherboard and attach only the modular cables required for your components to reduce clutter. Use the native 12V-2X6 (12+4 pin) PCIe cable to power compatible PCIe 5.1 graphics cards, ensuring the cable has adequate slack during routing. Power on the system and verify stable operation under load; the PSU is designed to handle transient spikes as defined by ATX 3.1 standards.
What to consider before purchase
Verify your GPU supports PCIe 5.1 and requires a 12+4 pin connector to take advantage of the native cable.
Confirm 750 W total power is sufficient for your CPU, GPU, and peripherals, including peak power demands.
Ensure your PC case accommodates a 140 mm PSU length.
Decide if 80 PLUS Gold efficiency and modular cabling are priorities for your build.
Usage recommendations
For optimal performance, route modular cables to minimize sharp bends and avoid obstructing airflow; keep the PSU inlet clear and allow ambient temperatures below 40°C for sustained peak performance.
