Do I have to get 1000watt psu
According to several calculators, my system uses 805-831 watts on its peaks. Should 850 watts be enough or should I go for 1000 watts?

AMD 8350 TDP 125W
R9 290X TDP 290W
Rest of system 100W

That's 515. I like to add 100-150W on top of that for headroom, so 650W would be good for that system.

I got 850 watts corsair Gold PSU, when I put my NEW AMD card in it, in the bios i can see the cpu is getting like 2.8volts only, I had to took several hard drives and dvd out to make get in optimal range, I guess after 4 years, my power supply is not as good as it was used to be anymore, time for new one basically. I was also facing lots of system crashes even b4 I put on the new card for last 6 months and couldn't figure out till today. I was one of the ones who didn't pay attention to PSU and paid for it. Let me know if you need any more info.
Also I had this strange problem, first time my computer turns on, it reboots(turns itself off all the way) itself off after like 5 seconds (b4 the video logo even shows up on screen), then it starts again automatically and finally goes all the way to windows on the 2nd start, I am also facing issues where when I turn the computer on, I get boot error and beeps, so I have to switch it off completely for 30 seconds and then restart and everything goes smoothly. And it happens a LOT! I hope new PSU solves the issues, I have basically replaced everything, my motherboard, cpu, ram, only thing I never changed was PSU

How about you post your system so we can see for ourselves.

Please list full system specs, but in general the calculators over estimate so 850 would be plenty. In general ;) .
