a few questions...
-for my build is a 550 watt power supply adequate if i overclock, i put in a 650 watt to be safe
-does the ram being 1600 and also being only 8gb ok for gaming?
-is the motherboard/CPU cooler good enough for overclocking to around 4.2 or 4.4 GHz?
-is the monitor that i selected any good (particularly for gaming)?
Thanks for the help guys!

the 550W should be enough but if u wanna go for a 650W if u have money won't hurt and u can upgrade ur other components in the future without being worried about power..
no the ram speed doesn't effect gameplay and 8gb is more than enough for now..when things start to heat up u can put another 8gb in the future..
the cooler should be fine but I'd got a premium one like nd 14/15 for better cooling which will help u oc ur cpu more..
the monitor I don't know but the benq monitors are famous among gamers cuz it's a good one..(wait till someone else tells about it monitor)
