I recently bought a new video card(EVGA GeForce GT 620) but then realized my Dell Inpsiron 660 might not have the 350w that the card requires. I have next to none education on power supplies and i only really understand graphics cards and RAM, can someone educate me on what things are required for a power supply to be compatible with my computer? Thanks for the help!

Most power supplies have a label on the casing telling you the wattage. There is no other way to check.
Just find the power supply in your computer (looks like a box with wires coming out of it) then try to find a label on it. Look for a number with wattage or W next to it.

If you cannot find the label, it is safe to assume the Dell has a PSU higher than 350W.

ok, but i would like to buy a new power supply. So what youre saying is the only thing that matters is the wattage? So i can buy and install any power supply i wanted aslong as it has the wattage i want? or is there like specific amount of wires i need or something like that?

Power supplies are pretty consistent in specs. Most have the nessacery features for modern computers and you would struggle to find one that did not. The main difference between power supplies is their wattage and component quality. You will only need a 300W psu for your system.
However, 300w psus are usually bad quality so it is safer to get a higher wattage one. Here is a cheap option from a very good brand (this psu is a good option to go for):
