I am wanting to upgrade an office desktop to dual monitors. It only has one VGA output.

Looking at getting a $30-$40 dollar video card just to support dual monitors, I don't need anything fancy. Lots of MS Office and Internet based work. Probably something like this.

I have the stock 350W PSU in it right now. My question is, will I need to upgrade the Power Supply? In general, how do you know how much power you need will need in a computer? (I don't see power requirements anywhere I've looked for that video card)

Thanks!
