the newegg recommendation is for total psu capability. the pcpartpicker is more accurate and counts each component. the general rule of thumb is a power supply is most efficient when the load is half the capacity. this will also leave room for overclocking. the system you listed requires 437 watts so a psu with capacity of 450 would work, but it would be running at full capacity and probably be noisey and hot. 150% isnt bad so 650 should be plenty. the more important factor is the brand and rating of the power supply. antec, seasonic, xfx, and evga all have good reviews based...

If you just plug in your computer and use it, the PCPartpicker is fine. If you overclock or want to add new stuff in the future you should use a larger power supply. Typically you want about 25% more capacity. And add about 100W for each part you want to overclock.
