Is my PSU causing my random shutdowns?

My system is in my sig but basically I keep getting random shutdowns and I've gone through everything to make sure there are no loose connections or malware. I have my cpu overclocked with a 1.35 vcore as well. I have had this fortron psu for almost 2 years now and I can't believe it's failing already. :confused: also, it's DEFINITELY not an overheating issue as I am always watching my temps are all in the low to mid 30s. Memtest also finds no errors.
 
I would go back to stock speeds and see just to be sure never know maybe your OC is unstable.
 
I'm at stock speeds now and it's running ok now with no weird shutdowns. I have a feeling my PSU isn't enough for an overclock since it has 15a on both the 12v rails. Do you think that would be the problem?
 
For that video card, you generally want at least 20 amps (combined effective amperage, not just the sum of both rails added up) on the 12 volt rails. I honestly do not know how well that Fortron unit of yours can combine rails. Some power supplies are very efficient at that, and the combined amperage is closer to the sum of the rails' amperages, while others have combined amperages that are closer to only one of the rails.
 
^^^What he said. I would try and borrow a friends PSU if at all possible and try overclocking again. If not possible a new PSU never hurts.
 
Yes, I have used core temp a few times (ver 94) but I heard about how it could cause shutdowns so while I still have the program I never ran it. I stick with everest to monitor temps. I'm almost positive it's my PSU that can't handle my system. I have a corsair 520 coming tomorrow so I'm sure that will be enough. My system is being pretty stable now although it's crawling at *ugh* 1.8 ghz :p

An update please!! Did the new PS fix your problem?
