I thought that if you run it on 1 PSU...those power "leaks" from it (since most of modern PSU have 80-90% efficiency), would be smaller...but no...I just did some math...and saw that its exactly the same...the only small "problem" is that you need 4 PSU's instead of 1...but since they can be 250-300W each...it's no such big deal either cause they can be found on ebay for few $$$ only - or for free if taken from some old nonworking computer (and some people will even pay you if you take them with you....so there is also possibility to earn with F@H...AMAZING! ).
