Hi! So I don't know if to send my pc to an expert so he can change the PSU for me for 65 dollars. I already have the PSU I want to change but I feel a bit scared because of bad experiences I had when I was building my pc. I'm changing from a EVGA 600w 80 plus white to a 850w Rmx full modular. The funny thing is that I want to be a computer engineer and I feel scared. :/ Should I challenge myself to doing this? Also, I would be asking lots of questions when I start with the process(today) just to make sure. What you guys say? An expert for 65 dollars or myself?
