PSU duration period

Alot of manufacturers provide a MTBF in hours. For instance, my last PSU had a MTBF of 100,000 hours, or 11 years of continous use.

That said, depending on the build quality of the PSU, the unit is more or less likely to degrade over time. The reason your PSU is not the piece of hardware to save money on is because when a PSU fails, they have a reputation to destroy other system components when they go out. So, saving 80$ by not buying a new PSU could potentially result in 400$ worth of dead motherboard and CPU.

If your unit is made with solid capacitors from a reputable company, it may be relatively "safe" to continue and use it. I personally upgraded my PSU after about 5-6 years, and kept the old one just in case I have any problems.

Mine chieftec gps-550W is around 6 years too and works perfect still with i5-4670k @ 4ghz, gf 670 and 3 hard drivers. About half year ago fan broke down [my computer is on 24/7 most of the time] so I just bough new 12cm fan for 5$ and used some tape to put it right below the orginal one and its working flawless since then again :p

I'm going to say double the warranty period. So if warranty was for 3 years, then I'd start to worry after 6. There are a LOT of things that can change this. If you live in an area that has "dirty" power I'd replace it sooner. I'd also keep an eye on it if you have major electrical issues like lightening strikes, etc. TBH I've always replaced my PSU early because I usually need something my old one didn't provide. 8pin PCIe plugs, 8pin ATX AUX plugs, etc. I just moved to my 450W gold rated PSU because I didn't go CF/SLI and wasn't using the 750W that I bought. I'm not sure who "frontech" is but if you got 6 years out of it it's time for an upgrade. You probably need a total system upgrade.

With a fx 6100 i doubt that if it's still good enough for the ts,but a new psu wouldn't hurt to keep the system running for a longer time.

@ kaushik,
Do you have problems? Because of the question.

6100?

I mentioned total system upgrade because a 6yo PSU doesn't have the connections on it a modern system would need. 8 pin PCIe and ATX AUX plugs, etc. Probably has only one or two SATA plugs. 6yo PSUs are meant for powering system that are also 6yo. And I for one wouldn't want to use such a system.
