I personally would go for a 620W Enermax Liberty (www.ascent.co.nz) this will give room for upgrade and has the ageing factored into it :nerd:

554325 2007-05-30 08:40:00 This is what I am referring to:

+12V1@20A,+12V2@17A

buyraidmax.com

or

www.enermax.com.tw

+12V1 0.5A/22A /+12V2 0.5A/22A


As for what a GTS draws or not, whats wrong with getting a PSU that will last a few years? Instead of worrying about it all over again when the next graphics upgrade comes along.

Hold up.

20A on one rail and 17A on the other one doesn't mean you can draw 37A.

For example, in the second link you posted, only 36A can be drawn from the two 12V rails even though the two rails added together is 44A.

The first PSU will probably be more like 30A. That would be a perfectly good PSU to use, but it's not 37A.

Also, no one is suggesting getting a crap PSU, in fact that is about exactly the output and price range I was suggesting.

Sorry if you already know all this, but it seemed like you were saying 17+20=37.

554326 2007-05-30 08:48:00 A cheap $80 550W Task PSU like the one I currently have should just fine. It gives you 36A (18A+18A) on the 12V rails. qazwsxokmijn (102)

That will do, it's not a quality PSU but it will handle the load fine.

I have a $380 850W psu. It also works fine.

Yes I do know all that . And the ATX 2 . 0 standards too which say how much should be permitted on each rail and all that . I read all these articles too .

But its easier to say get one with 37a - I mean how do you explain all that in a couple of sentences when you are recommending something .

20 + 17 means it is sufficient for most systems . With a bit to spare in most cases .


Or 22 + 22 = 36, or whatever .

Ah .

If that's what you meant, I totally agree that it's a good spec for this PC . It probably ONLY confuses people like me and Graham who try to analyse it :p
