GTX 470 might not be powered sufficiently by OCZ 600w?

[Averagegai]

I read that the GTX 470 requires 38A on the +12v rail, but my PSU only has 25A on the +12v and 25 on the -12v, I think...

Can someone confirm if that's enough for the GTX 470? The exact model of the PSU is OCZ ModXStream Pro 600w.

Also, if my 12v is rated as 12.368v in the BIOS, can that damage my card? The tech support told me that the function range of the card is only 11.9v to 12.2v. Is this true?

Anyways, I went out and bought a Corsair TX750w, but it's still artifacting when I'm booting up so I returned it.

I'm in the RMA process at the moment, and I'm worried my OCZ 600w PSU might damage my new card if I put it in.

Do you guys think the PSU damaged the card?

that ocz psu has 2 +12v rails if i remember correctly.

Could the high 12.368v rating have damaged my card?

Your PSU has 504 watts available total for the +12 volt rail that is equal to 42 amps total. http://www.ocztechnology.com/images/awards/mxsp_wattage_charts.jpg
The 12.368 volts is well inside the ATX std +/-5% and should not damage anything.

So it should be safe to use it when my GTX 470 comes back, right?

I would think so but the Corsair TX750 is a better PSU with 1 large +12volt rail. If you have to take a money loss on returning it I would just keep it and use it.

Returning the OCZ would be a big hassle since I got it in a combo deal with the GTX 470 (~$360 after instant savings + mail-in rebate). Looks like I'll just use the OCZ for now, thanks for the replies guys.

I think you need a more pweful PSU for the 470...like 850 or 1050
look at the Ultra X 4 PSU.....Tigerdirect has 2 video reviews on them

BUMP for some more confirmation.

If the rest of your system is using 350w or less, you'll be fine I reckon. Disregard the tosh about 850w PSU's and such.

I would think so, the rest of my system is pretty basic.

PII X4 965, 4gb G.Skill Ripjaw @ 9-9-9-24 1333mhz, 1 optical drive, 1 1TB 7200RPM Samsung Spinpoint, and 3 120mm case fans.

Nothing is overclocked at the moment, and I don't plan for now.

You should be good to go then.

 

[rolli59]

You should be fine with the OCZ. It meets the recommended specs and some.

Im running a GTX 470 on an OCZ 650W (OCZZ650), and it has 4 rails. No trouble at all, even with 100% CPU load and 100% GPU load.
