PSU calculator - need ideas

just found it several days ago, and was playing with it since then.
seems to be pretty accurate, suggests about 20% over which IMHO is necessary. I have here a pretty basic wattmeter, according to this, my config draws peak (furmark+prime95) ~450w out of the wall which sholud be about 340-360w counting with 80+ efficiency. (yeah, I do not have plenty of headroom with my 425w enermax but haven't encountered any problems since yet)

could you guys please try it with your (honest) config to find out whether it is reliable or not?

The lite version lacks +12V loading calculation.

I use this calculator: http://web.aanet.com.au/SnooP/psucalc.php and the result was every accurate to my own readings (+-5W).

I use the OuterVision lite one. Set it at 10% "aging" and toss it all in. It's much over-estimating, but it's still better to have nice headroom.
