I need to upgrade the power supply in my Precision T3400 for the new GPU i'll be installing in it, so i just bought the Dell YN637 525W power supply. I have searched the manual, and i don't see anything in there about how to properly remove the old and install a new power supply. Can anyone give me some tips on how i can approach doing so? Thank you

I was reading into it a bit, and looking inside the tower, there are wires leading from the PSU underneath the CPU itself and out to the hard drives. I read one person so it's best to cut the wires off the PSU and take it out that way. They said the long way would be to take the CPU out completely then reapply all the thermal paste. I really would rather not cut them or remove the CPU honestly
