Hi.
I have this 350W ATX power supply from 2005 and I decided to recap it and maybe boost it up a little.
Here is the schematic diagram for it. Many people here have the same PSU as I can see.
I have already replaced the two biggest caps (originally 330uF/200v) with 470uF/200v. Now I'm after the caps on the output rails and I have the following doubts:
1. Can I double the capacitance of C18, C22, C23, C25, C27, C28, C29, C32 without any consequences?
2. Can I use 6.3V caps on 5V rails? The original caps on 5V rails are 10V rated.
And a general question. Do C1 and C2 need to be low esr too?
I do not have much experience with switching supplies and the main reason I'm doing this is because I wanna learn something new.
