Do I need a more powerful PSU?

Hardware Build a PC
1

I have been putting together a build for my first go at a mid-range gaming PC. 

Several of my friends have recommended that I get something more powerful than a 550W PSU.

 Am I good with just the 550W or is there some truth to their suggestions?

You'd be fine with the 550W for this build, but if you plan on doing some upgrading in the future (which most of us do) then it's safe to say to go with a 600w - 650w

I would go with a 650w personally just to give myself plenty of elbow room for upgrades without worrying about the psu.

Thanks! I might just end up going with the 600W then.
