12v Rail on power supply failing

[crushsquid]

Hello guys, I contacted corsair about this problem and they were no help.
First here is my rig:
Motherboard: Gigabyte GA-Z97X-UD5H-BK
Memory: 2x4GB Patriot Viper Xtreme
CPU: i5-4670k @ 3.5 Ghz
Graphics Card: PNY Geforce GTX 660
PSU: Corsair 600W

I believe I an having a problem with my power supply. Whenever my computer is under somewhat heavy to heavy loads I have noticed that my graphics card, cpu, and hard drive would all turn off for a few seconds, and then turn back on. After that happens I would exit whatever resource intensive program was running so I could prevent any damage to the parts in my computer. Also, the power supply that I have should be more than capable of supporting all of the parts in my computer. I believe that it is the 12v rail in my power supply that is malfunctioning, as all of those things are operated by it. I am submitting this to ask if there are any remedies to this, or whether I got a defective model and need to submit an RMA.

Thank you for any help.

Im guessing its a CX600. If so then the cheap caps it uses are probably starting to fail. It's a somewhat common occurrence with the CX series.
