Firstly, let me say the configuration pages of the website are, in general, excellent. They allow you to play "what if" games with possible configurations - are the components compatible, have I enough space/power/cooling etc. That is really helpful. However, when it comes to overclocked PCs I think there is a flaw. Put the same PC configuration in as a standard desktop - and, separately, as an overclocked pc and you get the same power consumption. Clearly that can't be correct, an overclocked PC may take more - may be tens of watts more. Not an issue if your PSU has lots of headroom, but certainly the case if you are getting close to the limit.
All that said - brilliant website!
