I have had a corsair GS800 for about 2 & 1/2 years on my PC that is on about 16 hours a day for almost every single day those past 2 & 1/2 years. I was wondering what the lifespan should be if its used every day for 16+ hours at a time.

I don't know about that specific PSU but in my case, the PSU lasted for over 8 years in similar conditions (the fan started to become noisy after like 5 years). It died 2 weeks ago, and it was just a Deluxe 450W cheap PSU that came with the Case. I think it varies on the specific build of your PC. If you are overclocking a lot and stuff like that, it might not last for that long. It also depends on the electricity provider (Here in Romania, I had situations when the power went down for a few seconds every night (my PSU cooler started to become noisy after this kinds of things)

My Corsair C?650 recently died after 6 years of use similar to yours.. I thought that was good going so replaced with a Corsair CX750M. I noticed their top of range come with a 7 year warrently.. so if they give a 7 year.. they probably expect it last 10.. .. anyway .. gives you some idea.

Heat, heat is the enemy of all things electronic. As long as your PSU is kept cool it can last a very long time even when being run continually (I run all my PC's 24/7). As SteveSkills points out, even no name PSU's can last a very long time. Things that will help your PSU last longer; 1) clean the PSU out, when cleaning out the dust from your PC, give the PSU a little attention also, there are heatsinks and other areas to catch dust in there, keep those clean. When the PSU is unplugged from the wall it is safe (and I recommend this) to put the canned air's plastic wand down inside the PSU to work the dust out. 2) Keep load on PSU about 50% of it's rating. 50% is the magic number where almost all PSU's are at their most efficient, it is also a load that does not put too much stress on the PSU.
Keeping the PSU clean, cool and not overloaded, I expect about 7-10 year lifespan from my PSU's (even at 24/7 operation). Will I get 7-10 years from them? That remains to be determined. I had one PSU that was still working at 12years so you just never know.
