Hey Mom - I have a new graphic card that I would like to install but box says needs a 350W power supply. I have a 300W in the box. Should I risk it and try it or beef up my wattage first? Could it cause any damage to the card or motherboard if I ran light on wattage? Thanks !

I have never personally ran into that issue..but...

If the power supply doesn't meet the minimum requirements damage could result to your computer, the video card, or both.

Yeah it might blow your power supply if it's underpowered. Most likely your comp will just randomly shut down. Could damage your mainboard and videocard if it blows.

I always recommend getting a real power supply vs a generic one(the ones that come with the case) Get an antec, thermaltake etc.. 400W should be good enough. The generic ones will blow up and destroy motherboards etc if you push them too hard...

What about going over on wattage? I.e. 500-650W?
Any probs or just extra heat?

Nah, should be no problem. Your computer will only draw the amount of power it needs.

Here's a pretty helpful Explanation (http://www.pcpowercooling.com/technology/myths/)

Thanks very helpful. One last question... Seems like you have to be really careful on the physical size of the PS if you want it to fit right in the case. Are there 3 or 4 "standard" sizes or do you just have to carefully measure?

an ATX power supply will fit in an ATX case. it shouldn't be an issue for you

I got THIS ONE (http://www.circuitcity.com/ssm/ULtra-X-Finity-500-Watt-ATX-Power-Supply-ULT31844/sem/rpsm/oid/159269/catOid/-13015/rpem/ccd/productDetail.do), and it kicks ass. It's pretty quiet, and the cables are designed to help air circulation. It's 80 bucks at Circuit City, but I think I only paid about 40 online. I can't remember who I got it from, though.
