Corsair VX450W 450W Power Supply

With a faster processor, graphics card, and a more feature-packed motherboard, we set out to see how these units react when having to power a little more hardware goodness. This system configuration pushed about 275W at maximum, which is above the “typical” load which Corsair claims its maximum efficiency levels (i.e. 225w).

With this system configuration, we see similar results compared to our low-level tests, as the Corsair VX450W delivers the lowest watt usage at these varying load points. The numbers get close between the two Corsair units at higher wattage levels, but it appears that the new kid on the block is a bit more efficient than its older brother.
