@nas93 For how many years the PSU has been running on your system. I have the Tough Power Series 850 Watt 80 Plus Gold - The New Fully Modular One
http://www.thermaltakeusa.com/products-model.aspx?id=C_00002130
I got it from a shop owner I know , very reliable Used on It SLI 970s , and 980Ti
There is the DPS G version which is the newest with a software that monitors the System voltages
http://www.thermaltakeusa.com/products-model.aspx?id=C_00002389 - I am not sure if it is available in Lebanon.
But I do not think you need an upgrade - your PSU is just good and not jeopardize the performance of the 980Ti. It is a Tier Two PSU
Tier Two
As above, just slightly lower quality. Still safe to use and are all stable for any PC of today's standards, including Haswell C Stepping certification and 100% Japanese Capacitors. It is rare to find a PSU here with Taiwanese Capacitors and perform very well here, but they are here just in case.
