Product information

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.

Key specifications

  • Total output power: 750 W
  • Efficiency: up to ~91% (80 PLUS Gold)
  • Motherboard connector: 20+4 pin ATX
  • GPU connector: native PCIe 12V-2X6 (12+4 pin) for PCIe 5.1 graphics
  • Fan: 120 mm rifle bearing
  • Operating ambient: guaranteed performance at up to 40°C
  • Capacitors: 105°C Japanese main capacitor
  • Input voltage: universal 100–240 V AC, 50/60 Hz
  • Form factor / length: compact 140 mm
  • Colour: black

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.
