I agree with PostmanPot: the graphics card companies exaggerate the PSU requirements by a BIG margin to cater for poor PSU's!
eg.
Then you can add like another 15W for the HDD, and 95W for the CPU (eg. i5 2500) and another 50W for good measure, which would translate to roughly another 14A on the +12V rail, which would bring the total current requirement on the +12V rail to under 30Amps !
If you have like an i3 2100, 1x HDD and the reference design GTX560Ti, you can easily run it off a Corsair CX430 (+12V rail @ 336W or 26A).
On the other hand, if you're going to overclock the GTX560Ti to like 950MHz and you have like an i7 2600k that you're also overclocking to like 4.5GHz, then there is no way that the Corsair CX430 / Gigabyte Odin 585 will be able to handle the load, because you're almost going to double your power consumption if you overclock that much. In this case I doubt that even the CX500 will be able to handle the load. The GS600 on the other hand would run it like a dream.
You can always use http://extreme.outervision.com/psucalculatorlite.jsp as a reference. Please just select like capacitor aging of like 10-15% as a safety margin. Unfortunately that calculator won't really help you with a PSU size when you're going to overclock, unless you know beforehand what your CPU speed & voltage would be - both at stock and overclocked speeds.
Lastly, try and go for single +12V rail PSU designs, otherwise you'll end up like a friend of mine where some of his HDD's work and others don't, just because his PSU has like a quad rail design, and you'll have no idea on how those rails distribute the power!
eg.
Now the reference Nvidia GTX560Ti is rated for 170W TDP, which would translate to roughly 15A on the +12V rail for the graphics card.

This is probably a bit off the topic, but I don't think it justifies a new thread, so here goes....
I have the Gigabyte Odin 585 PSU (2nd one, 1st one failed after a year, this one now just over a year young...)
My problem is this: As of about two days ago, the PSU fan started making unearthly noises. Dust being the culprit I presume. Does anybody else have this problem with PSU fans in general or know how to fix this? This is not the first time that this has happened to me, and the last time I had to replace the PSU in the end. I regularly clean my PC with a vacuum cleaner & air pump to suck/blow all the dust out (while keeping the fans still as to not damage circuitry....). Since I cannot replace the fan without voiding the warranty, what do I do to stop stop the noise? Vacuuming/air blower seems to work for a little while, but then it starts up again...
In general, what do you guys do to keep your system dust free? I'm at the verge of building a box consisting of air filters to put my PC in....

Probably why you have so much experiences with "kak" psu. Putting and advocating low power psu's for top top graphics card.
You have this unwaivering believe these newest graphics card will run on those underpowerd graphics cards.
The Graphics card companies is in fact understating it in some cases.

Here below is some of my sources form my spreadsheet. I referred to alot of different manufacuters and the end i settled with an approx figure.

^I disagree with that, I've successfully run a 6850 on a 400w PSU and it was a crappy thermaltake too.
It's still under warranty so RMA it.

This list that Rock Bottom Computers gave is quite a nice reference guide, but it is most definitely not the smallest you can go 
Just take note that those recommendations are for PC's that won't be overclocked or with many hard drives in them. He has also suggested a good selection of PSU's (ie. no Huntkey / Gigabyte / Coolermaster / Thermaltake).
It is almost always better to go for a bigger & better PSU, because then it will run cooler and last longer too.

Feel sorry for "all" those customers of yours you've lied to.
You've now been proven wrong twice in this thread.
You quote manufacturer recommendations (which are grossly exaggerated) while selling quality PSUs (even small ones which completely negate what said manufacturers say).

My advice has now been called "BS" my recommendation "KAK" and my opinion a "lie"
What a nice person you are.

Has nothing to do with what kind of person I am.
Wrong is wrong.
I take it you then have no comment on the CX430.
One could argue that I am such a nice guy that I actually go to the lengths I go to to correct misinformation. Anyway, that's off topic...
Have a nice day.

My opinion on the CX430
Corsair makes great psu's
Can it run a GTX560. Yip. Should you do it? Probably not if you can avoid it.
You could put a VW1300 in a Bentley, but you probably should not.
I guess you will call BS and Kak again.
"Has nothing to do with what kind of person I am."
It most certainly do.
The manner in which you differ from others says alot about you.
One can agree to disagree without being a jerk. There is a difference between Frank and being Dick.
This seems to be your modus operandi here. Bashing others with opinions differ from yourself.
Your opinion on the MSI and EVGA link?
Have a nice day yourself.

You're smoking something strong. You provided incorrect information. When challenged you provided further misinformation.
Agreeing to disagree?
Bashing with my opinions?
Wrong again.
Good luck with your venture.
