I am currently looking into purchasing a new PSU for my PC.

My current PSU is http://www.amazon.com/Thermaltake-Su...KA0CCW5VJYDYCB

Given my budget, I am looking at http://www.amazon.com/Antec-Earthwat...Y30ZEM38CETB8D

Is the Antec Earthwatts 650W sufficient for a build with an R9 290 and i5 4690K? I only have one HDD and will maybe put an SSD in eventually. No crazy power hungry components besides the R9 290.
