      Should I worry about the drop from 10V to 6.3V??

      6.3V 3300uF, I have no problem with... The sky's the limit with these, there are plenty of these in 10mm.

        No. - It's on either 5v or 3.3v so either works fine.

          Are those big 10V caps on PSUs always either 5V or 3.3V, or are they sometimes really 10V? In other words, is it always safe to replace them with 6.3V? Forgive my ignorance.

            The standard output voltages of an ATX power supply are +12, +5, +3.3, -12v. There aren't any voltages from 6.3v to 10v so there's no need for a 10v capacitor on the output side. There could be 6v-10v on the input side or anywhere in a proprietary power supply.

            If in doubt solder a cap in a measure the voltage. A 6.3v cap will run at 10v long enough to measure it.

              What severach said.
              The rule only applies to the final output caps.
              Voltages between input and final output could be anything so those you'd have to check to be sure.

                I just tested the 350-PN... There are six "big" caps. Two of them were 4.82V, two were 12.9, and two were 3.36, so to answer my own question, none of them were unique to the design. They each just represent a different "rail".

                I'm about to re-cap this with Panasonic FK and FC. The FK has better spec than the Teapo SC, so I'm glad I listened to you and did not use the Samxon RS. Thanks.
