post #1 of 10
Thread Starter 
Hey all. Just went 570 oc 850/1700/2000 sli I'n my set up with i7 950 @ 4.0 vcore 1.27

Using ASus probe my 12v is at 12.20 at idle then when I load it up
It drops to about 11.7.

Also when I'm playing metro max settings with 3d vision about 5 min I'n the pc freezes

Am I in need of new psu.

Thanks.

Try running the OCCT PSU test, it loads your PSU as much as possible, if it crashes you need a better PSU

How about trying M2033 without any overclocks and see if it freezes.
If it still does, try it in 2d mode.

Software voltage monitoring is worthless. Use a digital multimeter.

11.7V is well within spec regardless.

It drops to 11.7 just stressing the cards.
So if the CPU gets stressed I think it's dropping even more and freezing. I can't test both at the same time.

Voltage software isn't accurate, don't even use BIOS.

To find 12V power with a multimeter, touch your red probe with a yellow wire and your black probe with a black wire from the same plug. You can use the plug to the video card.

Try using the OCCT PSU test.

And as already said, 11.7v is well within specs and software monitoring isn't particularly accurate either. Apparently my 12v rail drops to 0.23v for no reason.

Why would you want a new PSU? The one you've got is a top tier unit built on the SeaSonic M12D platform.
