I have ordered an 11% overclocked 980ti (6pin+8pin), I have got in i5 3470. My system consumes about 181 w. I have a Thermaltake tr2 80bronze psu. It provides 42A at 12V rail (504W). Will this 980ti work ok, given 181+250=431? And if anything could I lock the boost to keep it from going to the full 250W.
180W system plus Gtx 980ti on a 550W PSU?

Should work fine, no worries. 
How do you get 431w? Is that the whole system? I actually think the system wont go above 350w at load.

funny, im quite sure that psu would break down within the first 2 days.
you need to replace it.

431 is 181+ 250W of 980ti. 181 is my whole system w/o graphics card. i5 3470 is just 77W. The rest is not that consuming: 1hdd, RAM-1333, simple motherboard and 1 fan.

But your system without gpu will not use 180w if that is everything you have in it. probably around 100w so +250w from the 980ti is around 350w at full load. 2 gtx 970 at load + processor etc use about 550w, im quite sure one 980ti and i5 will not use 430w.
But if you don't feel sure about then sure you can buy a better psu, after all it's your system so you must do what feel right You can also buy one of those wattage meters which shows you how much your system pulls from the wall.
Also how old is the current psu?

Unique_3 Technically you could power that system and GPU with that power supply. However, I wouldn't personally do it. Those Thermaltake TR2's have a poor reputation; especially the older ones.
I would be concerned about poor ripple suppression slowly damaging the 980 Ti and the rest of the system. When it comes to PC components, I admit that I have my favorites (further below). Were it me, I'd buy the power supply below. From my personal experience of owning two 980 Ti's non-overclocked with stock fan curves, I've seen each of them using 80% of max TDP; 200 watts. Add your CPU's wattage, plus the MB and other components, you're probably looking at 300 watts while under load. That's very close to the most efficient 50% consumption curve on a 650 watt PSU. In addition, it's rated at platinum efficiency, fully modular, EVGA warranty for 10 years. Right now it's at the same price point as the gold efficiency unit. The EVGA G3 is less money but I've seen too many customer review mentions of the aggressive PSU fan curve creating unwanted noise.

I used one of those online calculators which gave me the 431W for the whole system w/980ti. If as you say it would only use around 350W then the psu is not likely to fry. Only worry is thermaltake tr2 series have bad reputation. I have been using it for 3.5 years, with a gtx 660.

Those online calculators always exaggerate
I myself use an i7 4790+gtx 1070+2ssd+1hdd+3fans and 4x4gb ram on a 550w psu from antec and had no problems so far. Also I said 350w at full load, so that means every component running at 100% and I dont expect that to happen that often. But like I said if your feeling says you need a better one then get a better one, you can find very good psus for a decent price
Im not to familiar with the psu you have, but since you said 42a at the 12v rail it sounded like a decent psu TRENDING THREADS
