How much do yo think my current build needs, my current one is 850 watts. Here is my build, https://pcpartpicker.com/user/Guled/saved/vQJmP6. I also found a semi silver+ certified 1000 watts for the same price, (it's 80 dollars off!). Also would I pay more for a 1000 watt power supply then a 850 watt power supply if I'm using like 790 watts. I'm asking this question because I have a 430 dollar graphics card and a very expensive CPU. I saved up for over 4 years and don't want to get a bad power supply or make my parents pay too much for the electric bill.

A very good 550W PSU will handle R9 290.. You're safe enough for that build... Don't go for 1000 W (1 kW !!).. Extreme PCs with high end CPUs and multiple GPUs use 1000 W PSU.. Save money..

850 watt is overkill in my book. Go for quality 550-620 watt from XFX or Seasonic. Also I would change the 8350 to i5 4xxx and get a mid range mobo. :no:

evga g2 850w can even handle 2xR9 290 you dont need to go higher. if crossfiring isnt in your plans this would be more than enough and save some bucks.

I would like to add that your power supply should exceed your power demands by about 30%
