I know on the box/system requirements it says 750w but I've heard that the number was determined by being overly safe hence less is actually needed than what is put on the requirements.

So, now I'm wondering if that's true or not so I can figure out whether or not I should buy another power supply or just stick with this one.

*Other Notes* - I have mini-itx motherboard so in no way will my future be using more than one graphics card as it won't fit more than one.
