I would like to ask if this 450W PSU would handle this build or should I go for the bigger one 550W PSU? When I counted the voltage input it was about 350W but than some people recommend to times it by 1.5 which gives me about 525W which suggest me that I should go for the 550W PSU. I'm not planning to overclock any of my components so I'm not looking for anything higher than 550W PSU. Most people recommend to use SeaSonic 80+ Gold PSU. What do you think?
 
Solution
The PSU that you have selected is ample for the system you have specced out, especially since you do not plan to overclock.
The Seasonic is a high quality, efficient unit.
