Tweaknews posted a review on the FSP Group Booster X5 450 Watt Dedicated Videocard Power Supply

I can definitely see the niche that this product sets out to fill, and it does a good job of filling it. Available from the FSP website for less than $80 US, this is a great value for the enthusiast needing more graphics power but unable or unwilling to spring for a new power supply.
