How can i tell if my PSU isnt enough ?

Hello everyone, so long story short, i have a decently beefy setup (at least id like to think so :??: )

im running

Asus crosshair Formula IV
H50 cooling
4 huge mm fans(top / front /side/ back)
90g ssd boot drive
total of about 6-7TB of hdd space(although 3.5 of it is external now)
GTX470
amd BE 495 quad @ 3.4ghz
16 gigs of RAM

and a gazillion USB items connected to it.
Im running this with a 3 monitor setup

oh oh and a corsair 700W PSU

to which i just added a GTX 570 for the extra screens....

and so overall, with the addition of the 570 what im wanting to know is, how will i know if this PSU isnt enough?
i dont want anything to get damaged etc.

Thanks in advanced.

More about isnt
  1. 700watts plenty for that system
  2. 700 is more then enough, Corsair PSU's are vary good, so I wouldn't worry.
  3. The Nvidia GTX 570 and your system do not require as much power as you think. The Corsair 700 watt power supply is definitely sufficient for your system. No need to worry about it.

    Nividia recommends a 550 watt power supply with two 6-pin power cables for a desktop gaming rig with a GTX 570 video card. Both Nvidia and AMD recommendations are conservative. Both companies overestimate power requirements.

    Yesterday morning I looked at some newer power consumption charts for various games. You'll probably only use somewhere around 300 watts with brief power peaks somewhere around 400 watts.
  4. but to my system i have a 570 AND a 470 attached. does it matter? i only game on the mid screen btw and occassionally pt one game on one screen paused and another in the main....does it matter?
  5. OOPS! I misunderstood. I thought you switched video cards.
  6. Yeah i have a GTX 570 AND a GTX 470 in this system. Am i still good? thanks in advanced.

    Common indications of insufficient power:
    bad 3D performance
    crashing games
    spontaneous reset or imminent shutdown of the PC
    freezing during gameplay
    PSU overload can cause it to break down

    Bottom-line up front is that if you're PC currently has both GPUs installed and you're not experiencing the above indications during high-load environments, then you should be good.

    How many internal HDD? What is the model of the Corsair PSU (I'm guessing it's the GS700V1 but want to confirm)?

    Edit: Corrected some spelling.
  8. ^If it works properly it's enough ;)
