Will my PSU handle my planned upgrade?

[jawknee530]

I have a Corsair hx520 right now. My plan is to buy an EVGA 8800gts 320 and "step up" to the 9800 when it's released. I also plan on getting a quad core penryn when they are released. will my current psu cover this upgrade or should I have purchased the 620?

I wouldn't be suprised if the 8800GTS pulls only a small amount more power than your current Radeon 1950pro....ATI cards are always power hungry, as for the G92 no one besides the R&D at Nvidia knows...nothing solid has even come out about the card. Penryn is a die shrink of Conroe and thus it should pull less power than Conroe. Your current PSU should be fine.
