Hello, Whats the best PSU to get? I had a 300W one and changed last week for a 450 Low Noise PSU. I know I wont need 450W and it will probubly do me no differernce but is it worth having that extra bit more? I was going to get the 600W one but it was faulty, so I had to take it back and get the 450W one. I think 300W is plenty, What you guys think?
