Best online PSU calc?

[Admiral Huddy]

Can anyone recommend a decent PSU calc?

I've come across this one
http://www.extreme.outervision.com/PSUEngine

but it seems to suggest too much..

For example, it suggests a 925W PSU for a quad core GHz C2D, 2 sticks of DDR2, 2 SATA HDD, 3 x 120mm LED fans, 1 DVD/RW drive, deskyop Mobo and a soundblaster, a 8800 GTX (no OCing)??

Thought I'd get awy with a 650W

What do you think..

this one seems more realistic.. recommends 638W for a generic brand and interestingly only 368W on a decent branded PSU..

It doesn't have latest C2D processors or AMD..

I think i'll stick with the second I mentioned.
