Question about adapters.

[Dan2rock4]

I'm getting an adapter that converts my one molex to 2 molex on my 500 watt psu, my freinds say this will work even if the cards min requirement is 500, but they waraned me to not play heavy games on super high setting, is this correct?

What make/model of power supply are you using with what make/model of video card?
