Recommended Posts

these boards like good clean power and lots of it remember that you'll probably upgrade a componant or too and you don't want to be upgrading your psu everytime get somthing that will last a generation or two

Well I was looking at Antec's PSU's, and the highest they go on the 12v is 19A...so does that mean that none of the best selling PSU's can work with this mid-end Vid Card?

 

Even OCZ says its highest is 18A on the 12v.

 

Am I reading these charts wrong????

There's more than one 12v rail on the high end PSUs. I can't speak for that 450, but I know the corsair and ocz models have several 16-18 amp 12v rails.

So does that mean that you add the Amps?

 

So say the Video Card says it needs 20A on the 12v (Link from 1st post)

 

Do you add the 2 12v rails? I haven't seen a PSU that has 20A on one 12v rail yet.

Yes you add the 12V rails to get the max. amperage! BTW: Read this!
