The GTX 980 Ti owners thread.

Hi guys, recently picked up a 980ti and within 2 minutes it blew my psu :(

This is the PSU it took out. (the 520w version)

I know I was pushing my luck, and leason learned.

Thankfully, like realy thankfully! It only took the PSU out, everything else is ok.

I had a spare unused OCZ psu, slightly more powerfull, as shown

I was simply too lazy to swamp them out beforehand, now the 980ti has slapped my wrists, will that PSU feed this beast or am I still asking for trouble?
 
Not sure about the quality of that PSU but I was getting system shut downs with a SF 550w. I stuck a 980 in that rig instead, and when I do eventually downgrade one of my 980ti into that rig I'll probably pick up a 750w unit.
 
Am I reading this right? So the OCZ I'm using now (shown above) does 4x 18amps across the 12v rails so, 72amps?

I can't find any other 600w that can do that, and this psu is proberly 8 years old, but just used for first time today.

I was looking at replacing it with https://www.overclockers.co.uk/evga-600w-80-plus-power-supply-100-w1-0600-k3-ca-025-ea.html but the stats say it's worse than what I have now? It can do 49 amps on a single 12v rail.

Would you keep this OCZ 600w in a rig?
Found an old review http://www.hardwaresecrets.com/ocz-stealthxstream-600-w-power-supply-review/ but there was no hungry 980ti's back then.
 
Multi rail PSUs were slightly flawed as they would only have certain rails attached to each plug. So in high power draw scenarios you might only be using 1 or 2 rails because different rails are attached to different PCI-E cables.

This is from a while back so could be utter guff but I seem to remember this was the issue.

I think most high end PSUs are single rail designs nowadays.

Nice read that actualy makes my OCZ seem safer than some of the more modern single rail ones.

Do you think that 600w EVGA would be ok with a 980ti though, I feel naked not having a backup on the shelf. Will never go SLI, so don't need to go too crazy.

Safer yes but if it's one of the earlier multi rail types it won't be able to actually deliver all its power in a normal single card setup so you could overload it too.

Id be much happier with a single rail design like that EVGA.

That review of the OCZ states that all the PCI-E cables are on a single rail, so that's 75W through the PCI-E slot and a further 216W (12x18A) available via the PCI-E connectors, just under 300W in total. The 980Ti has a TDP of 250W so should be ok, but if you start overclocking it's a bit tight.

Thanks, those numbers check out nicely. I'm pulling ~100w idle and ~350w gaming, so it is tugging some 250w down the 12v rail.

Hopefully this one will just cut out if overloaded and not go bang like ye olde 520w OCZ.
Will stick with it for now.

In other news, my old gpu was a 760, so upgrading to this was quite the step up :D
It absolutely blitzes eveything I throw at it (1440p)

hi, i just reinstalled windows 10 pro , with the latest nvidia driver, also installed OC Guru II , but the clocks are just greyed, ive used this before and not had issues, and know my stable clocks , i think this is a newer OC Guru II then i used last time , cant find what the older version was and where ]

if anyone can help would be great , i know others use MSI afterburner , but this worked fun before and could control the LED's on GPU , thanks

What clocks are people getting? My EVGA 980Ti Hybrid is boosting to a max clock at 1366Mhz - Not going over 52C. This is using Precision X with a 10% (110%) power increase. What else can I use to maybe go over this limit, as Precision X doesn't seem to want to let me.

The 110% power target is fixed, so you can't go any higher. What are you over clocking it to?

I would add 100 to the core and 200 to the memory and start from there. My Zotec can hit 1500mhz boost and 7800 memory for benchmarking, however I am gaming at 1450 and 7300memory.
TBH I would expect your card to achieve 1500 plus and be stable.

I am sure someone will let you know what their similar card can do. However best thing is to try it out your self.
