VS400: the entry-level power supply with high-end features
The Corsair VS400 is a great choice if youre building a home or office system with lower power demands, but you still demand the compatibility and reliability that Corsair is known for.

Real power
The VS400 delivers a guaranteed 400 Watts of continuous power. With 0.99 Active Power Factor Correction, you get the peace of mind from knowing that your components are protected from uneven power delivery. And, a dedicated single +12V rail saves you from the hassle of balancing your components across multiple power cables.

Low noise, high efficiency
The 120mm fan is thermally controlled, so it only spins at maximum speed when its pushed hard and even at full load, its pretty quiet. The VS Series reaches 80% or greater efficiency, so it generates less heat, and youll enjoy lower energy bills.

Sophisticated design
The black powder-coated enclosure and the black-sleeved cables give any system a polished look. Youre building a PC, not a battleship, and with the VS400 you can avoid that look of unpainted steel that youll find on so many entry-level power supplies.

Reliability you can count on
VS400 is backed with a three-year warranty, and you get lifetime access to Corsairs legendary technical support and customer service.
