No. Video editing takes ram, the more the better. It also takes processing power, which the A series APU's are lackluster. Windows 10 will have a hard time running on 4Gb of ram, not that it takes up that much, but any working applications do.
You'd be looking at Intel i5-6500 and 16Gb ram if you don't want to be working on the same project next week.
There are better psu's to be had, cheaper. Try a corsair cx450m. @$30.
SSD will be your best friend with video editing. Constant i/o from a hdd will get very old, very fast as video files are not exactly small. For budget builds a 120Gb is ideal, this is where you'd keep the actual software, but the video itself save to hdd.
