Reviews & advice about my build + some questions

[jjg2013]

So I believe I got everything I need for my Rig. This will be my first build.
But I have a couple questions still.

Is a 1000W PSU needed, or can I go lower? If I can go lower I'd like to stay with 100% modular if possible.

Should I buy and extra cables? or extensions? If possible link to the type of cable or just let me know so I can look it up.

Tools? I hear just a basic Philips and good lighting is enough.

I think that's all the questions I have. I let you all know if more pop up.
Thanks in advance!
