Please check my PC build

I am building a PC for my Dad, he is a teacher, therefore he mostly browses the internet and works with PowerPoints etc.
Recently he has wanted to make videos and screen capture, to make presentations for his classes.
His PC is long in need of an upgrade.
His budget is about £300 (GBP).
The following is the build I have planned for him. All constructive critisim is welcomed, I would like opinions and suggestions on the planned build.
The RAM is on the motherboard's supported hardware list, and the CPU cooler has enough clearance for the case.
Do you think 500W is overkill for this system, could I lower it to 430W?

Mother Board
Gigabyte GA-F2A88XM-DS2
CPU
AMD APU A10 6700
RAM
HyperX Genesis 2 x 4GB
PSU
Corsair Builder Series CX 430W
Hard Drive

CPU Cooler

Okay thanks for the advice, I'll look into it.

Sorry I forgot to mention that I want to be able to use multiple monitors, will that be possible with an APU setup?

Agree with the APU thing, in that price bracket.

I have updated my build to an APU build, please take a look. :)
