PSU Confusion!!!

EDITED:
Hi, :)  I’ve bought an Evga 8800GTS KO ACS3. It will need 28A on +12V rails. This is the PSU I’ve chosen.

http://www.thermaltake.com/product/Power/PurePower/w004...

My confusion is about the Single VS Multiple +12V rails. 8800GTS need 28A on +12V rail. Does this mean combined +12V rails (if it has more than one +12V rails, like this one) OR one of the two +12V rails? It has 52A on combined (14A+23A+15A) +12 rails but it has highest 23A on the single +12V rails. So which will count – the highest single one’s A or combined rails A. This is where I get confused. Please help.
Thanks in advance. :D

first, you can't just add the max rating of each +12V cause it doesn't mean that the PSU can provide it at the same time (for more information check PSU 101&102 at the sticky)

On the TT site it says that you've got a combined 52A which is more then enough for you!

where did you read the second rating? maybe you've looked at another model?

as for the number of rails, though one rail is better most of PSU has more then that and it won't cause you problem with the video card.

The Pure power line from Thermaltake isn't all that great.


Apperently they re-did the PurePower line.
52A sound good to me.
