2 12V ratings?

[Panda Man]

Just out of curiousity, why is there 2 12V ratings on some power supplies such as the Antec TruePower 2.0 TP2-550 EPS12V ATX12V 550W Power Supply? And is +12V1@19A, +12V2@19A good? B/c it would seem to be pretty poor if its only 19A...

its a good thing

It just keeps things more stable when overclocking and such.... isolates componenets so their power draw doesnt affect others as much.

It's NOT poor if there's TWO at 19A. It would be poor if there was only one at 19A.

ok, thanks. I was just a little confused when i saw that, im used to seeing one rating, like +12V@28A or something. So that could power, say, an AMD FX-55 w/ Geforce 7800GTX SLi? (maybe pushing it with this PSU, but you get the idea)

With that kind of hardware, i would get an OCZ powerstream 600W. It would be ok if it were 2 7800GTs but GTX hog more power.
