My power supply is a 600w OCZ GameXstream and it is over 3 years old and has been running basically 20/7. Maybe 16/7 at the least. But over the past year, the house i've been living in has very very bad electrical work. Frequently my power goes out in the middle of a gaming session or doing stress testing so its using a very large chunk of power at the time of a power outage. So my question is, since everything in my system is also overclocked with voltages as well, (ram, cpu, video card) should I still trust my power supply for the next 2-3 years when I go to buy a new gtx 560 Ti as an upgrade. Is it possible that the power supply could be faulty at this point could damage other components and may have already done so? In the sense that it could be impeding or have already done permanent damage to my processor, ram, or motherboard?
-TL/DR - Old power supply ( consecutive power outages/voltage drops) 1) Should I keep/replace 2) Will it damage future parts if I end up keeping it? 3) Is it impeding my performance or have already done permanent damage to components?

One of my systems is essentially identical to your present system (OD'd Q9550, 4 GB DDR2 RAM, GTX260-216, G'byte EP45-UD3P).
Running 3 instances of Prime95 and 3DMark06 (my standard load to check power consumption) to load the CPU and GPU, the system pulls 300 watts from my 80% efficient power supply as measured by my Kill-a-Watt meter.
I probably would not replace the PSU until I upgraded to a 560 Ti. Then I would go to a good 650 - something like a Corsair TX650V2 or XFX 650 (both built by Seasonic) or the Antec equivalent.
I will not buy an OCZ PSU. They now have 4 or 5 PSU lines. One is pretty good. One is OK. The rest are, umm, excessively mediocre. And I never can remember which one is which.
