Corsair VX450W Power Supply Review


Corsair Introduces A 450W Mainstream PSU

Now that Corsair HX620W and HX520W power supplies have been released for nearly a year, it’s time to release some new models. Why bother with a 450W model when the 520W and 620W models are doing so well? Price, of course! The new Corsair VX family of power supplies incorporate a single +12V power rail that is designed to deliver continuous power under heavy loads while keeping things simple inside the unit. By reducing the specifications on the VX450W, the power supply is significantly less expensive than the HX620W power supply. Corsair informed LR that the MSRP is $85 and street price is going to be around $69~$79, which is a bargain seeing how the MSRP on the HX520W was $119 and the HX620W was $169.
