300 is WAY too small for anything but a minimal system. 500 is gonna be plenty as long as you have a single graphics card, that isn't too big. Just make sure its got the things you need. there are 20 and 24 pin motherboard connectors if you don't go cheap you'll end up with a PSU that can cover both. I'm not sure if they still make PSU's without the 4 pin 12 volt MOBO connection but just make sure its go, if your mobo needs it. (its easy to spot just a square 4 pin connection near CPU) If your graphics card needs PCIe power connection make sure that's covered too.

number one rule: DO NOT go cheap when it comes to PSUs you will regret it its worth a few extra dollars to get something dependable that actually puts out the Wattage and voltage that it advertises. getting a cheap one can end up in a burnt up CPU.
