High-wattage ATX supply for modern GPU builds

The COUGAR GEX 1000 delivers 1000 W through an ATX 3.1 design that includes a native 12V-2x6 cable for PCIe 5.1 graphics cards. Full modular embossed cables reduce clutter and improve airflow inside the case. One hundred percent Japanese capacitors back long-term reliability for demanding systems.

Integration into a high-power system

Five PCIe 6+2-pin connectors and three SATA power connectors support multiple add-in cards and drives without adapter cables. The 20+4-pin main connector fits standard ATX motherboards. Because the unit is fully modular, only the cables needed for a given build remain installed, freeing space for larger coolers or additional storage.

Thermals and acoustic profile

A 140 mm FDB fan runs at low speed under typical loads, earning a Cybenetics A+ noise rating. 80 PLUS Gold certification confirms efficiency up to 91 percent, so less waste heat enters the chassis. Comprehensive protections — OCP, SCP, OVP, UVP, OPP and OTP — guard components during transient power events.

Questions about this item

How much continuous power can the GEX 1000 deliver before hitting its limit?

The unit is rated for 1000 W maximum output, so sustained loads up to that level are within its design specification.

What noise and heat levels should I expect from the 140 mm FDB fan during all-day operation?

Cybenetics rates the fan A+ for noise, and 80 PLUS Gold efficiency up to 91 % keeps waste heat low even under continuous load.

Which cables must I already have to connect the native 12V-2x6 GPU plug?

The power supply ships with the 12V-2x6 cable included; no separate cable purchase is required for PCIe 5.1 graphics cards.
