I have an older PSU and I am dumb about PSUs

[FoldingZebra]

Will my PSU:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817371009

Run This:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814130622

??

I tried looking at the info on the PSU, but I dont know know if it will work.

Thanks.

It has 64amps on the 12V rail, which is plenty for your GTX 570 choice.

Umm, how did you come by that? Based on the specs on New Egg:
+3.3V@25A, +5V@30A, +12V1@25A, +12V2@25A, +12V3@25A, +12V4@25A, -12V@0.5A, +5VSB@3.0A
I don't see it...

Based on the review, I got 64amps: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story2&reid=58

Notice JonnyGuru shows the 12v rail to be 18A versus Newegg's shown 25A (which is a misprint by Newegg). After that, I exammed the images on Newegg and Image 3 (I believe it is that one) shows the screen shot of the specs on the side and they show 18A versus 25A, as well.

So I'm confused. I read the article, but it's all over my head a little. The 570 says it needs minimum 550W PSU with a 12v rating of 28 amps. If I understood the article, only one of the 12v rails actually powers the video cards? So wouldn't that mean It's only 18 amps? Sorry for lack of understanding on PSUs, but I have to start learning sometime!

Thanks!

You are fine...

Basically, there are four 12v rails which each PCIe connector goes through it's own, along with other connectors. Since your card basically has two connectors, it is drawing from each one providing the required 28amps needed.

 

[FoldingZebra]

oh, it's adding 2 of the rails together. Ok thanks

 

[tecmo34]

Yes... It is okay

Kewl, so if a PSU only has two +12V rails and 2 x 6Pin PCI-E Connector, such as: http://www.newegg.com/Product/Product.aspx?Item=N82E16817148028&Tpk=N82E16817148028
and a GTX 560 requires a Minimum recommended power supply with +12 Volt current rating of 30 Amps, it would work without probs then?

I'm looking at:
+12V1@22A, +12V2@24A
which would equal 46 Amps when both +12V rails are used on the GPU, which is more than it's requirements. Is that correct?

Not really a misprint, Antec revised the specs, Newegg didn't change the pictures
