deciding on a good psu

What so you mean a psu can be dual rail but you effectively you cant run them together..

eg a psu with dual 12 amp rails, if you cant combine the rails your pc will only draw off a single rail?
 
As I understand it from the thread ( which at the time of writing is about 2 below this one ) in some situations dual rail PSU's are having 1 rail overloaded. Swapping to single rail cures the problem as the combined load is below the total, it's just that one of the two rails is getting swamped. Therefore, especially when using ATI solutions, Single rail PSU's or ones you can choose single/twin such as tagans are the safest option.

Excactly if you have a PSU with 2x15A and one rail is loaded with 8A and the other 17A you get an overloaded rail, even though the total is only 25A when you wouldn't have a problem with a single 30A rail
 
so wich tagans can combine the rail

the black series?

the modular ones?

480w back
or 400w modular

need to keep the price around that mark
