The only feedback you will get here is people's opinions. The model you linked is plenty big to power the system - it has 52amp on the 12V rail. The question is, when is it going to crap out, and has it degraded over time?
The manufacturer's rated MTBF (mean time before failure) is 100,000 hours, which equates to over 11 YEARS of continuous use.

Back to your question - I just replaced a corsair identical to yours about 6 years old (but I had the 550 watt version). The thing was rock solid and I was very happy with it. I waited until I could find a good coupon deal, and ended up with a Seasonic platinum rated 660watt psu for 79$ after MIR. That is currently what's powering my GTX 770 + 3570K @4.3ghz.

So my recommendation would be...

So my recommendation would be similar - start looking for a really good deal, I'm sure your current PSU will be adequate for a while. You could probably get at least another 1-2 years out of it. That said, you DO NOT want the PSU to die while running on your new system. I have heard horror stories of PSUs going bad and taking other parts with it (motherboard, CPU, you name it....).

Again the MTBF is 11 years, but no one is going to buy you a new PC if that thing fries and takes your expensive components with it...

The Corsair TX series is a good quality PSU. Your particular one has a 100,000 hour MTBF (Mean Time Between Failures) rating. What this means is that theoretically, even if you left your machine on 24/7, it should last ~10-11 years before failing. What would be of more concern to me would be the capacitor aging that occurs. As capacitors used in PSUs age, it becomes harder for them to provide maximum (full load) power at a continuous level. So a brand new quality 650W PSU would have no problem delivering 650W continuously. However, over time it will struggle to keep that up.

The end result of my explanation is that you are probably fine with your older PSU since a system using a single GTX 770 GPU is recommended to have an ~575W PSU, but that does not include any overclocking. When overclocking, I tend to recommend adding 50W-100W to the recommended wattage. So a brand new 650W PSU would be ideal. However, with a 6 year old PSU, your overclocking ability may no longer be there. I'd say you are probably fine with using the PSU for now, but if you notice graphics issue(s) and/or oc'ing limitations that others with similar components are not having, then you might want to consider getting a new PSU.

Sorry for the long-winded answer, hope this helped. :)

Thanks alot guys! I am thinking of upgrading to a corsair RM850 to prepare for an additional 770 and possibly some overclocking, but now i know I don't necessarily have to rush it.
