Hi, I was thinking to buy a nvidia gt 640 but its system requirement is a minimum of 350w power supply but my own PSU gives the maximum output of 350w. I know I can't buy the gt 640 because my psu output is too small.
Do you know any graphic card that fit my system without the need to change the psu.
My PC could be the worst PC in the world because it has a intel dual core e2xxx of 2.00Ghz.

The suggested power supply rating typically means your entire systems power draw. It is not telling you how much your card alone will draw.

That being said, if you have a 350W power supply it is extremely likely you have a poor quality power supply that might not be able to give its rated output. This should be replaced before you upgrade.

That being said, the card does officially fall within your PSU's specifications.

It might help other people help you if you opened your box up and checked the make and model of your current power supply. Some folks on here know a lot about these, and could tell you whether it is decent or not.

This benchmark shows that the GT 640 under load does only draw ~140W.

Again, I don't particularly recommend you buy any sort of GPU upgrade without a quality power supply... but it might work.

I'm wondering, what is your current setup/card now?

For dual core e2xxx of 2.00Ghz, I think any upgrade are useless, better save money to build a new rig... :)

Can I use the Radeon HD 6670 for mine. I am asking this because here they have explained something.
