Enough power for 570 ?

[mateso]

Hello, new here. (sorry for my bad english)
Im planning to buy in a near future GTX 570.

This one:

or
http://www.gainward.com/main/vgapro.php?id=449
they are a bit overclocked

Will my PSU have a chance to survive ?
It is OCZ StealthXStream OCZ600SXS 600w
http://www.newegg.com/Product/Produc...82E16817341010
It has 4 12v rails

+3.3V@36A
+5V@30A
+12V1@18A
+12V2@18A
+12V3@18A
+12V4@18A

Max combined capicity on a 12v line is 580 W

System specs are:

Win 7 Home Pr 64bit
AMD Phenom II x4 945 (3.0ghz Quad core.)
4gb DDR3 1066mhz
WD caviar Black 750gb
OCZ StealthXStream OCZ600SXS 600w psu
GAINWARD GeForce GTX 260-216

Thx for any info

Yes, your power supply is fine for the GTX 570.

Yes it should be fine

I couldn't find a required amperage for the 12V rail on the Gainward site. EVGA's 570 SC (the slightly overclocked version) requires 38 A on the rail. You might get away with it by putting the 6 (eg. on 12V3) and 8 pin (eg. on 12V4) power connectors on different rails, but I'm not sure about it.

Just to give you some psu load figures to look at, my main system is a [email protected] with a 570 in it. And when running Furmark and OCCT/Linpack, my APC UPS software was showing a total load of around 575 watts on my system. Since my psu is a Seasonic X-650 (80 Plus Gold rated), I figure that the actual load on the psu to be around 525-550 watts. I imagine that your Phenom won't pull any more power than my 980X (probably less, depending on your overclock), so I would guess you would be OK at least on the short term. If you keep a significant load on it by running a DC project like Folding@Home or Seti that loads both the cpu and gpu, then you might think of upgrading down the road maybe.

Should be fine, though I'm a bit worried about that GTX 260 in your setup, are you planning to keep that for Physx? If yes, you might be a bit tight on wattage with both cards in the system though I haven't seen wattage numbers when running Physx. If you count both cards at full power you are probably right at the limit for a 600 watt power supply.

I am running an overclocked Gainward GTX 570 GLH, with a 9600GT for Physx, on a Core2 quad Q9550 at 3.4 OC, 4x DDR2 modules, X-Fi sound card and a couple SATA hard disks with a Corsair HX 620 watt power supply. No problems. I have a couple spare GTX 260's but I don't think I'd try one for Physx in this box without a power supply upgrade.

With the 260 for PhysX, that would be a problem. Good thing he didnt mention that! Otherwise, he is in good shape.

Your Seasonic is a single-rail PSU so it doesn't matter where you draw that power from. His power supply isn't.

Thats saying that its actually split. Just b/c the sticker says it, doesnt mean it is.

Regardless, I wouldnt worry about it...

To clarify, the card does NOT need 38A for itself like was alluded to in a prrior post.

 

[Brazen_NL]

Actually, it is split. I took the time to check the manual for him just to make sure he doesn't run into problems. (Check your manual, page 3.)

It's best to use 12V1 and 12V2. Combined, the overcurrent protection won't kick in until you hit 48A, so you got a little wiggle room to OC it, too. Overcurrent limit for 12V3 and 12V4 is 20.5A per rail.

So, unless you hit that limit you will be fine.

 

[EarthDog]

Im no expert... But what I would do is follow the instructions as to where to put the PCIe power connectors.

Look at the label and it shows you that PCIe2/4 are what you should use for the card. Again the CARD does not require 38A to run that is what is reccomended for the system.

 

[Brazen_NL]

Wow, missed the part on the label.

I stand corrected.
