Fair points from @ExChippie94 and @RetiredElectrician, but I'd actually push back slightly on the "overkill" angle.

@EdHamilton — quick question before you pull the trigger: have you actually logged your consumption over a full month yet?

Have you calculated your actual power draw? Gaming PCs can spike to 300-400W easily, and dual 27" monitors add another 80-120W depending on brightness and panel type.
