How much watts does my Power Supply gives?

[KoRn_KId]

I want to get the ATI Radeon 9800 Pro 128MB video card for my Sony® Vaio PCV-RX650 computer, however I don't know how much Watts does my power supply has which I need to know in order to see if this video card will be run properly. I check the online manual (pdf file) but did not find any info about it.

Is there a utility that will tell you how much Watts does the system has, or do I have to open up my system?

Any help is appreciated,

Thank

you need to open the case and read the lable on the power supply to find out what its rateings are.
