Ram has little to do with power cunsumption now days. The 5V and 3.3V rails always have more then enough current for your systems needs. The primary aspect to look at is the power bing drawn from the +12v rails. About 90% of your system gets it's power from those rails. So it's importand to know what your system's power needs are in order to find a good PSU. Check the PSU 101 link in my sig for more inofrmation.
I found the link it was on tigerdirect.com guess they dont update that stuff very often huh. Either that or they are trying to get people to commit to a higher wattage more expensive PSU.
Any way I'm a newby at this stuff so I read every thing I can find on PC builds.
Thanks for the tip!
