After installing a new 780ti my PC has started acting strange. When playing games my PC will just randomly shut off and power back on. Specs in Sig. My PSU is an antec 850. The card the 780ti replaced was a 680. I'm not sure what's going on here. Any suggestions? All drivers on system are up to date including BIOSes.
 
780Ti sucks a lot of power just like the new 290's do .. an old trick is to unplug things not needed as to bare min to make the system run which it should boot from one stick of ram.. fans/drives/ram etc.. as to see if the power supply is overloaded or needs replacing.

We use to rate video cards by amps on 12v rail and not overall power supply output .. i'm sure the 780Ti has a amp rating and your power supply also has a amp output for 12v rail.

Immediate shutdown, PSU issue is a high probability.
 
that power supply must be defective if it's the problem because it's enough to power 780 ti SLI with that system.
 
The PSU is about 5- 6 yes old. Its an Antec 850. If that's the problem I can get a corsair RM850 this afternoon.
 
5-6 years? Damn. How do you even have that card hooked up? I can't think of any power supplies that old that have an 8 pin. Some didn't even have 6 pins.
 
What? I have an old corsair 520 that is at least 5 years old and it has an 8 pin.


Yeah my Corsair 750 bought in 2009 (came out at least a year before I bought it) had multiple 6 pin and 8 pin connectors with half the 6 pin connectors coming with the 2 pin adapter hanging off the side.
 
Before buying a New PSU.
Try an older driver for now, install MSI Afterburner and add some voltage to your 780Ti card.
Also recheck power to GPU and reseat the card in the slot.

Im probably thinking a year or so before that. Even then though, you had to buy a pretty high end psu for an 8 pin. I remember I was excited about my enermax liberty 500w having 2 6 pin connectors.
 
Thanks guys. I'll try to reseat and I'll switch the cables to change what rails its using. Lastly I'll switch it out.
 
Cleaned and moved to a different 12v rail. So far its working. I still think I'm gonna change it out.

Good to see its working, but up the voltage a little, and I bet no need to buy a new PSU.
Although no harm in upgrading cause I do it all the time.
 
Damn. Just failed. Gonna switch it out. I bought a corsair RM850 just in case. I don't wanna toast my PC from the PSU failing.

why would he up the voltage? a 780 ti has plenty of headroom to oc without even touching the voltage. the card would be defective if it was not working at stock voltage.

Because its a known fact to me Nvidia cards can fail with default voltage,but upping the the voltage helps on some cards.
People like you suggesting new PSU without even trying anything is not right,his fucking 680 ran fine and he changed to a 780.

please show me one case where out of the box voltage is an issue on the 6 or 7 series. the voltage issues where on some 4 and 5 series Fermi cards that came clocked higher than the voltage could reliably handle. those cards where over optimistically binned by some card makers. voltage on Kepler is nothing like that. AGAIN if he had to adjust the voltage on the 780 for it work then it would be considered defective.

and surely you know that a 780 ti uses way more power than a 680? his psu is 6 years old which is pretty old for a pc component.
 
I checked the the System Event Viewer and it shows 7 Critical events Kernel-Power failure. Now im sure the PSU just cant handle the extra wattage of the VidCard.. Can this damage my hardware?

I would, sudden power downs are generally power source related. a 5-6 year run on one psu is awesome, but its time imo to get a new one.
 
You are either overheating or your power supply is overloaded. Of course, could be bad video card or bad ram or something, but most likely is overheating / bad psu / overloaded psu.
 
I only use Corsair AX supplies and Antec atrue Power news (made by seasonic).

i havr had one antec tpnew 650w fail me but was promptly replaced via warranty.

I know you resolved this issue but in the meantime a low cost psu tester can be a life saver to prevent needless headache and troubleshooting.
 
There's really no reason to run a 6 year old PSU anyway these days, unless you just like the extra heat in your house :) Hell, the Coolermaster 1100 I bought when I built my x58 rig (that sat on a shelf for the last 3 years due to incompatibility with the x58 board) is a 88% efficient unit.

Wow, just realized it's actually closer to 5 years old.
 
Try the 314.22 drivers. I had the same problem with the GTX 780, as well as my friend with the GTX 670. Problem with mine is that 314.22 is not supported, so I had to mod the inf file to make the drivers recognize the GTX 780.

All the drivers past the 314.22 has BSOD or restarted. My friend with the GTX 670 did the PSU replacement before rolling back the drivers, still rebooted out of nowhere. I have an AX850 that has been working well for a time, and I know it isn't my PSU. The driver rollback did the trick though, for both of us.

So, if it is still having problems, try the 314.22 drivers.

Also, some games will trigger the BSOD or restart, some won't.

see below...

perhaps read the thread?

I read the thread. Three times. I know he's not having problems any longer.

As I've said, if the PSU replacement does NOT work and gets a random restart, BSOD, or black screen, try the driver rollback. And yeah, I know how old his PSU is.

I said it particularly here:

Sigh. Maybe you didn't read my post.
