Ready for Modern Graphics Cards

The ATLAS 650 conforms to the ATX 3.1 standard and supports PCIe 5.1.

Its native 12V-2X6 (12+4-pin) connector allows direct connection to compatible graphics cards without requiring a traditional 6+2-pin adapter.

The 12V-2X6 cable measures approximately 600mm, providing additional routing flexibility during installation.

Always check your graphics card manufacturer's recommended PSU wattage before selecting a power supply.

80 PLUS Bronze Efficiency

The ATLAS 650 is 80 PLUS Bronze certified and provides up to 87% power conversion efficiency.

This helps reduce the amount of energy lost during power conversion while providing efficient power delivery to your system.

Stable Power Delivery

The ATLAS 650 features a powerful single +12V rail, delivering up to 54.1A / 649.2W.

DC-to-DC conversion technology is used for the 3.3V and 5V rails, while Active Power Factor Correction (Active PFC) further supports its power-delivery design.

120mm Rifle-Bearing Cooling Fan

COUGAR equips the ATLAS with a 120mm rifle-bearing fan featuring grooved fan blades and an integrated stabilizing ring.

The design helps minimize blade flex and turbulence while balancing cooling performance with operating noise.

Built-In Protection

The ATLAS 650 includes:

• SCP – Short-Circuit Protection
• OCP – Overcurrent Protection
• OVP – Over Voltage Protection
• UVP – Under Voltage Protection
• OPP – Over Power Protection
• OTP – Over Temperature Protection

Why You'll Love It

The COUGAR ATLAS 650W gives modern PC builders many of the connectivity features you'd expect from a current-generation power supply without requiring a jump to a higher wattage model.

You get ATX 3.1 compliance, native 12V-2X6 connectivity, PCIe 5.1 support, 80 PLUS Bronze efficiency, a strong single +12V rail, and comprehensive electrical protections in a compact 140mm-deep design.

For compatible builds that don't require the additional capacity of the ATLAS 750W or 850W, the 650W model provides a more accessible entry point into the ATLAS lineup.
