Question about the Extreme Gaming 3400 build. Is the 1200W PSU necassary or is it required if you plan to upgrade? I plan on getting a nearly identical build but won't upgrade it any further (no tri-crossfire but I will pop in 4 x 200mm fans), will a 850W power supply do the job or not?
Power supply in question is.
