I think my PSU may be failing! I set up my rig 6 months ago with all-new components. Recently my mobo detected power surges at random (I wasn't doing anything high-performance), which shuts down my computer for safety. Today my PSU emitted a high-pitched whine when I started gaming.

I'm reading that the power surge thing is common for ASUS motherboards, but the whine is worrying.

Here's what I'm using:
Corsair CX 600W (is this enough power?)
Asus Radeon HD 7950
Intel i5
Asus P8Z77-V LK
1 SSD
4 USB hubs

Any thoughts?

Check your PSU voltage levels on idle and under load (HWMonitor or AIDA64 should give you that info), each rail should be close enough to it's appropriate level (+3V at 3V, +5V at 5 etc).

Coil Whine is a worrying issue, could be an EMI issue or a defective PSU, the readings you're gonna check should give a more clear vision about which case it is.

As for the Corsair CX600w, the wattage should be enough, but I've no idea how much amperage it has on it's +12V rail, maybe it's not enough for the HD7950 (how much A does it need on the +12V rail I don't know either, search for that info to verify if your PSU can handle the HD7950).

Hi - Yes, some Asus Mobo's are too sensitive to PSU voltage's and shut down. Many users disable that feature in BIOS.

A good 600w unit is more than enough for a system with a 7950, so the issue isn't from 'not enough power'.

If that PSU is still in warranty, I'd RMA it now. If you have the choice, trade up from the CX series (RM, TX, HX), if not Corsair will replace it. They don't do repairs since they don't mfg them. The CX600 is mfd by CWT.

I did what you suggested. AIDA64 gave me a pretty good report of what is going on, though I'm lost on how to interpret everything. What I got was:

Voltage Values:
CPU Core 0.744 V
+3.3 V 3.328 V
+5 V 5.080 V
+12 V [ TRIAL VERSION ]
+5 V Standby 5.188 V
VBAT Battery 3.296 V
GPU Core 1.090 V
GPU Memory 1.602 V
GPU +12V 11.906 V
GPU VRM 1.003 V

Current Values:
GPU VRM 46.25 A

Power Values:
CPU Package 9.82 W
CPU IA Cores 3.56 W
GPU VRM 46.56 W

Ok, good to know that I'm not underpowered! Corsair's warranty on this PSU is 3 years, so I'll definitely see if I can get it replaced. I was hoping I wouldn't have to rewire!
