I have a Corsair GS 800 (2011 model) power supply.
This is connected to an ASUS Matrix 7970 GHz graphics card. I'm suspecting a major problem between these two components.
This morning the power supply started to squeal. It starts up about once every 30 seconds and goes for about 5 seconds each time it does. I also got the BSOD saying "Quota_Underflow". Now this has only happened once so it may just be an odd coincidence. What I noticed is that the LED indicator on the graphics card changes color from green straight to purple (http://www.bjorn3d.com/wp-content/uploads/2012/10/matrix-load-indicator.jpg). The purple means heavy load, only issue is that I'm hearing this happen right now and I don't have any games or graphically intensive programs opened.
I've watched this cycle through quite a few times this morning and I'm positive that the issue is between either the video card (which is from November) or the power supply. The first thing you hear is a squealing from the power supply (not way too loud, but it's definitely noticeable) and then the LED on the video card changes to purple. When the squealing is over the load indicator returns to it's normal green.
Using CPUID Hardware monitor I can see that the CPU VCORE is ranging from 0.828V (with no squeal) to 0.960 (when the squealing occurs). The video card power (VIN0) reads a very consistent 0.950 when there is no squeal, and 1.256V when there is a squeal.
i7 3930k powers are reading the following. (current value does appear to jump up to 40w at a time during a squeal)
Package min 14.49W, Max 71.41W
IA Cores min 5.39W, Max 61.36W
I stuck a pencil into the PSU (while running) to stop the fan. The squealing issue persisted even with the fan stopped (so I know it isn't an issue with the fan). I also stopped the fans in the video card (very temporarily) and the squealing continued.
I'm thinking it's a bad capacitor in the power supply, but I'm not sure. There is absolutely no overclock whatsoever on this machine and 800W certainly should be enough to handle all of this hardware.
My build.
Windows 7 Ultimate 64-Bit
Gigabyte X79 UP4 LGA 2011 Motherboard
Intel i7 3930k (3.2GHz six-core) LGA 2011 Processor
32GB G. Skill Ares series @1866mhz (in quad-channel)
180GB Intel 520 SSD
500GB Extra HDD
800w Corsair Gaming PSU
Cooler Master HAF 932 Blue Edition Case
Triple ASUS 24" HD Displays
ASUS MATRIX 7970GHz 3GB 384-bit Graphics Card
Logitech 5.1 Surround
Any help would be great. Thanks.
EDIT
Looking at task manager there is also a clear correlation between CPU usage and the squeal. I'm letting my computer sit at idle, when there isn't a squeal CPU usage sits at 1-2%, but once the squeal starts there's a clear jump to 7 or 8% usage for no apparent reason.
