FSP Group Booster X5 450 Watt Dedicated Videocard Power Supply Review
 

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.

quality 600W PSU are available at less than $80; making FSP booster obsolete; if you are planning to run Dual HD4870X2 or GTX 295 you have enough money to invest in a high end PSU anyway
