Compared to some of the high-end offerings that pass through HEXUS labs, these specifications look a little weedy.
But to dismiss the Corsair for this reason would be missing the point completely. That's why we'll be putting it up against the power supplies from FSP Group and be quiet! reviewed in our 400-500W PSU shootout.
The VX450W only comes with a single 12V rail and only one PCIe graphics (PEG) plug, suggesting Corsair doesn't believe it's up to the task of running top-flight graphics cards such as an 8800GTX, HD 2900 XT or multi-card configurations.
The power supply and the box that it comes in are mainly black, with radioactive-esq green highlights.
The back of the PSU has mesh to allow maximum airflow and this is pushed through by a low-speed 120mm fan.
According to Corsair, the fan noise is just 21dBA when the PSU is drawing up to 400W, increasing to 30dBA as consumption reaches towards 450W.
As you'd expect for a power supply, you don't get a great deal of extras. As well as the obligatory power cable there is a basic user's manual, a pack of cable ties, plus four screws to hold the PSU on the chassis; though we think that more in keeping with the strong brand image associated with Corsair, it's PSUs should be supplied with thumb-screws.
However the Corsair-branded bag is a typically nice touch from Corsair.
