i don't know the first thing about what im asking but i know that in order for me to get a better graphics card, i'm going to need at least 600w power supply.. my question is - can my motherboard hold a new power supply and if so what would be the maximum wattage i could buy for it

im 19 and i just want a computer that will play diablo III, starcraft II and counter strike source but im clueless about anything other than how to put a graphics card in a motherboard so all feedback is appreciated

thank you

It's not true that you need a 600W PSU to upgrade your graphics card.

However, the stock Enlight PSU this seems to ship with is crap, and I wouldn't use it anyway.

Given that this is a low end build and you will be somewhat limited by the processor, you will not be buying a very big graphics card anyway.

Here is a nice PSU at a good price:

This would be a good graphics card match:
