1050 W ATX12V power supply for high-output systems

The Cougar Polar 1050 delivers 1050 W of continuous power through a single +12 V rail and a fully modular cable set. It targets builders who need reliable output for multi-GPU workstations or overclocked desktop platforms. Japanese capacitors and a hydro-dynamic-bearing fan support long-term operation.

80 PLUS Platinum and Cybenetics A+ set

The unit meets 80 PLUS Platinum requirements, reaching up to 92 % conversion efficiency across the 100 – 240 V input range at 47 – 63 Hz. Cybenetics A+ certification confirms low acoustic output under load. These standards define the practical limits of heat and noise you can expect from this design.

Nine 6+2-pin PCIe connectors decide multi-GPU

With nine PCIe connectors supplied, the Polar 1050 can feed up to four high-end graphics cards without adapters. Systems that require more than nine PCIe plugs, or builders who prefer a shorter chassis depth than 180 mm, will need a different power supply.
