Oversized PSU an issue?
Posted: Sun Sep 14, 2008 1:44 am
I'm looking at buying a new case that comes with a 430W PSU (Antec NSK6580) - the PSU is an EarthWatts, so it has an 80 PLUS rating.
I calculated (using Antec's PSU calculator) that the most I'm every likely to require is about 300-340W depending on how many HDDs I might use in future - given the efficiency of the PSU, am I going to be using more electricity than I might be if I used a smaller PSU (e.g. 380W)?
Just not sure as to how efficient PSUs are when they're only running at say 50%.
