Hello to everyone :)
Wasn't sure if this was the right thread, but still hoping to get some answers.
I am hoping to upgrade my little brother's PC as a Christmas present, yet I am still very new to PC building.
At the moment there's a 450W PSU feeding power to i5 3470, a stick of 4gb 1600Mhz RAM (don't really know how relevant is this), some 7200RPM 500Gb hdd and just simple stock CPU fan.
Since there's a desire for better gaming experiance and integrated Intel Graphics solution doesn't cut it anymore I was thinking of buying a decent value-orianted graphics card. For intance, a overclockable gtx 650 or 7770..
So, my question is as follows - is the updrage safe with the old 450W PSU?
Thank you so much in advance :)
P.S. Have two more questions, yet, don't want to span the forum with multiple threads. Should I get additional fan or two for cooling if I get the GPU? And can I mix RAM stick's brands as long as the speeds and capacity matches?
