you should be good BUT you cannot have physx with a ati video card

I don't think so. You should be looking at a 750w @ 60amp psu for that.
Your's is:
Fatal1ty OCZ550FTY ~37A
Originally Posted by BradleyKZN I have an OCZ Fatal1ty 550W, and im planning on getting a 5870 soon. Now, I want to also add a dedicated physx card, something like a 9600GT. The maximum wattage for the 5870 is 212w which equals to 17.6A and the 9600gt is 78w which is 6.5A. When I see the mechanical drawing of my power supply, it shows that it has 2x12v rails, 25A on each rail. 12V1 runs the Motherboard and CPU, while 12V2 runs all the modular connectors. Right, so now for my question. When people find the wattage that the GPU uses, does that include the 75w that the PCI Express slot gives out? I.E. The 5870 uses 212w but only uses 137w from the PSU. The 9600gt uses 78w but only uses 3w from the PSU. You see, if the total wattage on those cards are on the power supply, 290w or 24.1A I would have a problem, because I wouldn't be able to power any hard drives or other drives. |

Where did you get 37A from? Have I missed something?

Which figures exactly?...212W and 78W?
Is that total power consumption of the cads (PCI-E + connector)?
Whatever the case, you cannot say if the card will use up all of the 75 W limit on PCI-E or part of it, untill you measure/look at the datasheet/know the design

Seems both, I nearly had a heart attack when you asked if it tested both

I have looked up 2 datasheets now, and still nothing.

| For this test we measure power consumption of only the graphics card, via PCI-Express power connector(s) and PCI-Express bus slot. A Keithley Integra 2700 with 6.5 digits is used for all measurements. Again, the values here reflect card only power consumption measured at DC VGA card inputs, not the whole system. |

Ok..
I went through the review you quoted.
It does look like they have taken both PCI-E and connector power into consideration.
Also, check this out if you havent already...
http://www.tomshardware.com/forum/26...l-power-hd5870
Notice that going from 1 card to 2 cards makes the recommended power supply requirement go from 500W to only 600W.
Since these figures are officially from ATI, I think you would easily be able to run your setup.
Also, doing some math...
out of 212, assume atleast 50 out of PCI-E (probably more like 60)
thats ~ 13A off the connector.
For 9600, assume 50W off connector (probably much lesser in reality)
thats ~4A
so you only have 17A going off the 2nd rail...
I think you should be fine.
To add to that, the techpowerup review said 'Maximum' case as done with furmark...unlikely to get those loads in games...ever...
so on the whole, I think you should be fine...
