Asus GTX 780 ti DirectCU II OC causes reboots ?

[weebs93]

Whenever I play a GPU intensive game or run a benchmark program my whole PC reboots itself.

Drivers are all up to date as far as I know. The only thing I can think of is that I'm not correctly wiring my GPU to the PSU, however I have tried pretty much every possible combination of wiring between the two components. I'll list my PC components below, everything is brand new (less than a week old). Don't really want to take it back to the shop as they charge $50 for a diagnostic test and it can take 3+ days to get it all back. At least if i work out what the problem is myself I can get a refund/exchange if there's a faulty Part.

Specs:
Motherboard: Asus Z87-A
CPU: Intel Core i7-4790
GPU: Asus GTX 780 ti DirectCU II OC
RAM: G-Skill 8GB
PSU: Antec HCG-850M
HDD: Seagate 2TB SSHD

Have you updated the BIOS?

Have you updated the BIOS?

I believe so. I actually had the shop update it for me because there was a problem with the CPU originally. I imagine it would be updated to the correct version if they did it then?

Just double checked if the bios was up to date, if it wasn't before then it is now but the problem is still there

UPDATE:

I just switched out my GTX 780 ti with my old Radeon HD 7850. Ran Valley Benchmark like I always have and it went through fine, no reboots. Could this mean that my GTX 780 ti is faulty or could it have something to do with the Drivers. Could it also have something to do with the Power supply?

I would imagine the PSU is more than enough to handle it... though I would double check if it actually supplies the right ampage on whichever rail it's plugged into. If the PSU is a single rail then it should be adequate... doesn't mean the PSU isn't the problem and you should probably have a look at that too.

Your 780ti could actually be damaged in some sort of way, perhaps take it back to the shop and show them what happens and let them test each piece that could be causing the problem.

Sorry forgot all about this thread. Took the card back to the shop and got a replacement and all is working fine now
