I thought I had to turn the push pins in the direction of the arrow, the instructions are probably the worst I've seen. There is literally one diagram which is useless and don't get me started on installing the 2 metal fan clips. I checked some reviews of the cooler and even most reviewers managed to install them wrong.

I'm changing the psu to a 750w but the 550w is fine for temporary use. Even if it managed to use 550w from the wall that would actually only be 467 with 85 percent efficiency. Don't see anything wrong with using 467w on this power supply.
you have that totally backwards

80% means that out of 550 watts drawn by the components that means AT THE WALL you are drawing probably close to 630 thats how it works because you are rectifying AC CURRENT into DC POWER and you always lose energy there in the form of heat

you are pretty close to maxing that PSU

If I get a reading of 500w from the wall, how much are the components actually using if the psu has 85 percent efficiency.

if you are drawing 500 from the wall then then components should be drawing about 400WATTS if THIS IS NOT POSSIBLE WITH TWO 570'S if its reading 500WATTS Total draw AT the Wall @ LOAD then your Wattage Meter is WRONG

I guess the power monitor must be faulty then ;) 380-470 at the wall in vantage

Of course they are, check the vantage link a few posts back. That is 300 total system not just the graphics card.
either you'er pc is running on black magic or the meter is off
I would be very interested to see what the meter reports with a different psu

My idle to load difference at the wall is 300-400w. I think that seems right for 2 gtx 570's

not according to the bench marks I am reading every benchmark says the GTX 570 draws any ware from 250 to 330 WATTS(just for a SINGLE CARD)

http://www.guru3d.com/article/geforce-gtx-570-sli-review/13

"Our test system is based on a power hungry Core i7 965 / X58 system. This setup is overclocked to 3.75 GHz. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). On average we are using roughly 50 to 100 Watts more than a standard PC due to higher CPU clock settings, water-cooling, additional cold cathode lights etc.

We'll be calculating the GPU power consumption here, not the total PC power consumption.

Measured power consumption

System in IDLE = 218W
System Wattage with GPU in FULL Stress = 578W
Difference (GPU load) = 360W
Add average IDLE wattage ~ 50W
Subjective obtained GPU power consumption = ~ 410 Watts

Mind you that the system wattage is measured from the wall socket and is for the entire PC. Below, a chart of measured Wattages per card."

From that exact same post
With 2-way SLI we noticed our power consumption for the cards peaked to roughly 410 Watts, that's JUST the two cards, not the entire PC !!
so add 100Watts for the Cpu and another 50 for everything else you are pretty much MAXING IT OUT
410+100+50 = 560WATTS http://www.techpowerup.com/forums/member.php?u=83420

Isn't the 560 from the wall. So that is around 470w or am I getting this wrong? Is it the usage at the wall that counts or what the components actually use?

I would Check the +12V voltage at GAMEing LOAD as draw approaches maximum the voltage will start to drop if it gets below 11.70v expect stability issues

its what the component'S use THAT'S THE WATTAGE RATING and is its PHYSICALLY IMPOSSIBLE for you to be using LESS POWER at the wall then the components are using so factor in a peak efficiency of 82% for you're model of psu http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=62
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story2&reid=62

Test
7 1A 1A 41A 522.9W/
635W<draw at the wall 82% .99 24°C/
36°C
3.33V 5.11V 12.15V
So my psu is fine with 500 reading at the wall (assuming that it's correct) :pimp:

if that's correct then you have some pretty low power using 570's

O derp but thats still 300 Wats lol
Yep but again that's total system usage (from the wall) not just the graphics card.

:) I have already ordered a 750w just to be extra safe!

ps: 1 more post for 1337
