which one of these is the better one? and will they both support my computer and my PCI-E slot? and do they have more then enough power for my rig+7600GT?
btw i have a Compaq Presario (SR1830NX)

they got pelny of power alright, ive got the antec one, it does its job, its broken tho cos the fan dosnt spin, but it still works, i thnk the enermax one may be better tho

20A is pushing it. The official word says you need a Minimum of 18A on the +12v rail for a Athlon 64 system. So you're kind of pushing it. I would buy one of those PSUs if I were you. I vote for the Antec Smartpower, looks excellent.

antec is a very good brand, ive used one for a year and that thing has never had problems.

so go with antec!

 

[misterfatal]

are u guys sure that antec has enough power? im not sure how to figure 2 rails.

You add them together. +12v1@17a and +12v2@19a = 36A.

 

[misterfatal]

cool, i think im going to just go for that one then, i hope they have a warrenty

antec is a highly trusted company

dont worry dude it wont fail you.
and if it does. then it does have a warranty

cool

^^ Lol, I was about to say the same thing.

It does have a warranty, but you won't be needing it.
