ASUS AI suite II keeps popping up a warning and I haven't been able to make heads or tails of of. the ENTIRE message is the title of this post. Picture:

-Asus m5 a97 r2.0
-Corsair gs700
-AMD FX 8350
-AMD radeon hd 7850

Constructed the computer 11 months ago, only started getting the warning recently after I formatted and installed AI suite for the first time.

More about : voltage 952

If the message is for real and not a software error, it is telling you that your PSU is not supplying the correct voltage on the 3.3V rail. Check it against another pgm like HWMonitor: http://www.cpuid.com/softwares/hwmonitor.html

Better yet if you have a multimeter, check the voltage at the 24 pin plug on the MB. You can usually probe the pins from the back side without unplugging it. Read between any orange and black wire: http://pinouts.ru/Power/atx_v2_pinout.shtml
The PC has to be on and running to do this.

The two programs give different readings; though, both are under 3.3v. I unfortunately don't have access to a multimetre. Any insight you can offer?

Relying on software like that for voltage checks is always iffy. That is why one should always keep a multi meter around to verify. If two programs both show it low, it might be a real issue, though.
+3.3V tolerances should remain withing +/_ 5%. So yours is (allegedly) low. The +3.3V rail is needed for CPU, RAM,MB, and chipset... I believe. Have you been having any crashes or other errors?

I just ran HWMonitor on my rig in my sig below, and the +3.3V rails read a steady 3.360V. I would borrow, rent or buy a small multi meter and check for sure before panicking.
