I'm deciding between a 500 watt PSU and a 600 watt PSU.
I currently have a 460 watt PSU that powers everything but my dvd drive, spare hard drive, and 2 fans.
I've determined 40 watts is enough to power my hard drive (approx 15 watts) and my DVD drive (approx 25 watts). Please correct me if these are bad estimates.
So my question is about case fans. What wattage do they generally use? I can't find this information on newegg hardware specs, or by inspecting the fans themselves. I don't have their boxes anymore.
Also I noticed that these power supplies only increase their amperage for the 5 and 12 volt outputs. Would fans be using only the 3.3 volt output? Would in increase in total wattage for the PSU even matter if i'm only adding fans?
thanks.
great answers, thanks. i'll buy the 600 as it's only 10 dollars more. – robertpateii – 2010-08-24T01:23:20.163
