What is a good psu for a gtx 980 ti?

Tier B+ or better, assuming you are not running HEDT/workstation:

550W is plenty if you aren't - again - running HEDT, otherwise you might need more.

 

If you want some more personalized recommendations, be sure to post the rest of your system and location where you are at (your local market may be different from mine).

GTX 980ti is a very power hungry card.
Back when i was using one i was using a 4770K on a Z87 platform with a 550W XFX XTR 80+ Gold PSU (a very good unit) but when i was playing battlefield online for more than 10 or 15 minutes the fan on the powersupply would go nuts...it would ramp up to max speed for like 15 or 20 seconds and then it would come back down...for a minute or so, and then rinse and repeat...

 

So yeah, the PC wasn't turning off or anything, but the PSU was suffering, and it was as good as it gets for a 550W unit. SO...others aren't wrong when they recommend some 550W PSU, but if you overclock the card a bit, and use an unlocked CPU, be prepared for that kind of stuff...

My advice is: PSU is a thing that IS future proof...so it's worth spending a bit more to get a unit that will last you for your next few builds with room to spare...

 

i ended up having to sell the 550W PSU and i replaced it with a EVGA G2 750W gold and now the thing is dead quiet and reliable.

I would recommend a 650W Gold rated PSU or better, that has good reviews.

Eh. OCed CPU? I ran my i5 2400 and MSI Gaming 980 Ti 6G off a CX450M without issue. It's a 225-250W card, as power hungry as any other high end card (similar power consumption to the 1080 Ti, 2080 Ti, and Radeon VII). It performs about on par with a 1070/1660 Ti at stock though, that's why it's considered power hungry. It eats a lot of power for its performance level, but overall no it's normal '80 Ti power draw. Actually far more efficient than the previous gen, my 780s pull similar power for much less performance.

CPU was running 4.2ghz but with only 1.2v on the core...so not really more power consumption than stock.

GPU was 980ti Asus strix running 110% of powerlimit with an overclock...that card was pulling very close to 300 watts under full load.

CPu was probably around 100 watts (i guess) with load.

 

I don't see how such a machine could run with 450W...i had an AIO cooler, some led strips and about 5 or 6 fans...and 4 SSD.

...and like i said, it was bringing a very well built 550W unit to it's knees.

 

GTX 980ti is a ginormous 601 mm square die...it's one of the biggest and more power hungry high end card ever produced (in comparison 1080ti is ''only'' 471mm²)

 

From my experience with them (i had a GTX 780, 980ti, 1080 and now 1080ti) the 980ti was BY FAR the hottest running and hardest to keep cool card EVER...it would heat up my gaming room noticeably in a matter of minutes...no matter what some skletchy websites may say about power figures, i go from my own experience and how it went down for me, take it or leave it.

I have two 780s, had two 980 Tis, had two 1080s, had a 1080 Ti, had a Vega FE, have a Radeon VII and a 1660 Ti now (had some other GPUs along the way too). 980 Tis were never really hot (Gaming 6G and an EVGA SC) unless they had no airflow. Same with the 780s (EVGA Classifieds), they don't get past the high 70s unless there's no airflow (like in an SLI 0 slot spacing config the top card will happily slap over 95C). 

My Vega FE running around 70% fan speed and doing furmark or F@H would heat my room quite effectively. Don't remember my 980 Tis doing that. One I put in an mITX rig (H200) and it still didn't break 80C, stayed around 77C. Only time I got one above 80C was to 83C, in summer, with no airflow to the card (single fan in the top front of an Evolv ATX, no direct airflow to the card cause I was a noob). Once I fixed that it stayed in the 60s and 70s. 

The RVII is harder to cool, especially on the stock cooler. On a custom loop it behaves much better, still pulls a lot of power with a +20% power target though. With MorePowerTool I can feed it even more, but drivers or something have been fucking me so even feeding it a 180% power target and 320W+ limit along with 1.3v doesn't really improve clocks. Runs a lot hotter at that too, didn't monitor power draw under those conditions but I'd imagine it's large. Rig under F@H load with the GPU at around 1880Mhz with a +20% power target and stock wattage limit (IIRC 250W) my rig (5960X at 1.3v + Radeon VII) pulls up to 380-390W (from the PSU, a Corsair RM1000i, would be about 8% higher from the wall). With the CPU under load that would climb quite a bit, under CPU only load with the GPU at idle it does about the same numbers lol. But that's an overclocked 8c HEDT chip from 2014 with a hungry Vega card. 

The 980 Ti I ran was at stock, didn't increase power target or anything since it was on a 450W PSU. i5 2400 was, of course, stock since it's not a K chip. My point is that the GPU isn't as crazy power hungry as you seem to think. Compared to similarly performing GPUs now, yes it is (1660 Ti performs about the same as a stock 980 Ti and pulls 130W max). Compared to how much PSU you can get for not a lot of money... nah you're fine. 550W is plenty for most configs. 

That said, @Ciorot what CPU are you running?
