So I'm building a budget pc - part picker list here:

all bought second hand an currently totalling around £70-90 but I am currently as to what psu I should get. I was thinking 400w-500w and hopefully £10-20 second hand or new. For example this:

any advice onto how much I should spend, if this option is sensible, etc. would be greatly appreciated.
Thank you.
