I'm bumping this because I've wondered this myself. 2+ 12v lines are cumulative. I don't understand the point of splitting the 12v lines into two. I'd rather have ALL of the current on ONE line, than split into two lines. Since they are indeed both cumulative, then they obviously must come from the "same place", right? So, I don't understand the advantage of this.Originally posted by: theslug
I've read through this entire thread, but I'm still confused about one thing:
Is it generally better to purchase a PSU with a high enough amperage on one 12V rail, or is it better to get a PSU with dual 12V rails as long as enough amps are supplied when necessary?
I might need to purchase a new PSU as I think mine is failing, so would the Antec TruePower II 480W be good? Right now I've got a 20-pin mobo with a 6800GT AGP card, but if I need to replace my PSU, I may as well get one that would be good for the future when I upgrade and go SLI. My main concern is whether this model will provide enough power. If not, what other models are recommended?
There appears to be an error on that Antec page. Note the location of the *. It is not listed next to the +12V2 current, yet below that they state "* +5V, +3.3V, +12V1, 12V2 maximum output 460 Watts max."
