GTX 560Ti power requirements?

post #1 of 17
Thread Starter 
I have an OCZ 550W 24A +12V power supply and am considering dropping in a GTX 560Ti card but I see power requirements for it are a 500W power supply (check!) but that it also requires 30A on the +12V. That is according to the Newegg page for the EVGA model.

Is that correct? 30A? Maybe I am not calculating my amperage correctly for my PSU.

Any remarks? Suggestions? Advice [besides links to new psus on newegg:)]?

Your power supply puts out a total of 50A on the +12V rails. You'll be fine with that PSU and a 560 smile.gif

So you add the two 12's to get the total? Gotcha.

Is 550W ok? I know it says 500W minimum. I don't have much to spare especially with an overclocked X4.

Yeah, you add all of the +12V rails to get the total +12V amperage. And yeah, 550W is absolutely fine for your system (including the GTX 560Ti of course).

I run a 470 on a 500w, you will be fine

absolutely wrong ...u cant add up the 12v directly...to the op if u had 50amps on 12v it means u have 12x50 watts=600watts hows it possible ur psu is 550 watt....
now on topic urpsu would be giving u max 40 amps combined on 12v rails so u would be fine with a gtx 560 go for it......

GTX560 is a 170w GPU. That unit can pull about 36a/432w on 12v so based on what you have, it should be fine for now.

Basically, whether my maths is completely wrong or completely right (I think ghost z is right though), you'll be alright with your current PSU if you add in a GTX 560.

to make it more clear the op's psu has a max rating of 450 watt on 12v rails...so basically it means 450/12=37.5 roughly 40 amps...although they have stated 25 amps per rail but they r not supposed to be directly combined....it just states that each rail is capable of providing 25 amps at peak individually and not combined....hop that clears out the rail amps doubt....smile.gif
