ATX 3.1 compliant 850 W power supply

This fully modular unit meets the ATX12V v3.1 and EPS12V v2.92 standards, delivering 850 W of continuous power. It carries 80 PLUS Gold certification and uses a 135 mm FDB fan with a zero-fan mode that stops the blades below 50 % load. Japanese capacitors and a full set of nylon-sleeved cables complete the package.

Builders needing ATX 3.1 power and quiet operation

The supply suits systems that require the 12V-2x6 connector for modern GPUs and benefit from silent running at typical desktop loads. Its 160 mm depth fits most mid-tower cases, but very compact chassis may not accommodate the length. Users who do not need the new 12V-2x6 connector or who prefer a smaller footprint should consider other models.

12V-2x6 cable rated for 600 W GPU power

The included 12V-2x6 cable can deliver up to 600 W to a compatible graphics card, which is the decisive specification for pairing this unit with high-end GPUs. If the target graphics card draws more than 600 W through that connector, a higher-rated power supply is required.
