seperate 12 volt rails?

thats basically a redundant PSU right?

this is one odd PSU.

1 rail is used for the motherboard and one for everything else. I prefer 1 rail so that power isn't wasted on the motherboard rail.

yea, 2 Rails isnt the answer esp when there really weak.

i got my zippy wishing it would at least last me the 3 years its warranty is for. so 45amps on the 12v should power to run 2cpus and 2 gpus :P

Meh, I'm more of a fan of the single 12v Rail. Loving the zippy... but damn that sucker is gonna hurt my wallet on this next build.

does anyone have a link for the power req's of the 6800 series overclocked and running default speeds?

i think tomshardware posted an article not quite sure.

well the enermax has 2 seperate 12V rails, I use the other one for the graphic card. enough for a 6600gt or 6800u, although the clocks I'm running arent anywhere near "xtreme".

There is a 680w model that has 4 12v rails I believe, but they are all pretty low amperage.

I dont like the split rails.

EDIT

those ones dont look too bad for a normal rig, but enermax isnt the top of my list for power supplies..
