Question on PSU in custom build system.

[FrozenDonut]

I had some feedback on a PC that I am going to build recently on here and was told that a 550w psu would be fine. However I have just realised that the GPU I have ordered says it requires a minimum of 600w. Here is the build, I will put 2 PSU's in and am just wondering which one you guys think will work best in my system:

Ram:

CPU cooler:

SSD:

case:

Motherboard:

CPU:

GPU:

PSU 1:
https://www.aria.co.uk/Products/Components/Power+Supplies/Modular+700-950W/750w+Cooler+Master+GM+Series+G750M+80+Plus+Bronze+5+Year+Warranty+Modular+Power+Supply+?productId=61004

PSU 2:
https://www.aria.co.uk/Products/Components/Power+Supplies/Modular+650W+or+less/550W+Fractal+Design+Integra+M+Internal+Power+Supply+Unit+?productId=63236

So PSU 2 is the one I was going to get and PSU 1 is the one I was looking at since reading '600w or more'.
Also the system is going to be used mainly for some light gaming but occasionally something more intense and more demanding like battlefield. How necessary is the CPU cooler?

Welcome any feedback, thanks in advance .

PSU1 is a little overkill if you don't plan on overclocking. But you do have the option of overclocking with it, and have a little more headroom for cap aging. So I would go with PSU1. I also like the warranty.

CPU cooler is unnecessary if you aren't going to overclock. But for the price, it gives a little peace of mind.
