As far as a overclock being unstable I had the same thing when I switched to 8.1 my oc was stable it seemed on wins 7 but win 8.1 would cause crashs. I am not sure the reason why but benchs are also lower on 8.1 vs 7 so I use wins 7 again now. Maybe wait for someone who is a guru on why the os are like that to respond. As far as mine and strongisland1 response to it being a power supply you only gave us the led lights details not that when you used wins 7 it worked but not 8.1 those little details change things now.
I am not saying your psu is dead I am just saying the amp rating for your psu may not be quite high enough its 62 amps on the 12v rail and a 780ti classy if thats the card you have needs a MINIMUM 42 amps on the 12v rail thats everything at stock no overclock. Shike is always right on with psu but the unit is a year old I dont think he quoted a ti classy since they have been out for only 6 months.
I never said about different OS issues? Did you not see my two posts up above mentioning it? Here, let me quote it for you.
I also have a 780 classy not a 780ti.
He recommended me that PSU for the 780 classy. Even strongisland1 posted in a thread i made before about buying a new PSU and they told me that 750W was definitely enough for a single 780 classy + i5-2500k.

I am using 337.50 and now i even used the WHQL before that, im still getting the same problems. I tried both BIOS, the normal bios, and then the modified bios i got from this thread a year ago... it was perfectly fine in Windows 7 i had no complaints until now.

I have tried both BIOS, on my card, same result. I am on stock clocks on CPU. I pass on benchmark with no crashing at stock clocks. But i crash in any game when i overvolt.
When i plugged in my win 7 SSD, ran Firestrike extreme; I scored 6000 at a +284 GPU Offset and +800 Mem offset @ 1.38v. Completely stable. This was a bench i did a couple months back; and i get the same exact score when i run it again.
Overvolted to 1.38v on the GPU and 1.70v on Mem Voltage. Both stable and passed.
I have no problem in buying a new PSU i just dont want to buy one and then realize it wasnt my PSU..... ): But umm.... okay i think ill just wait for some more answers or strongisland1's answer....
See, it even says 1350+ mhz on the core, and 7ghz Memory. I cannot even get a +5 OC stable in windows 8.1; but in Win 7 i can do +284 easy lol... Same exact hardware i have right now. And my PSU is actually 10 months old; not a year old; just found the invoice on Newegg.... So youre saying my Gold rated Rosewill Capstone is a bunk and didnt last longer than my Thermaltake TR2 RX PSU which lasted me for two years? LOL! Thats really sad ):Edited by Aesthethc - 5/15/14 at 2:26pm
