Hi,
I'm currently in the process of re-capping a NOS (new old stock) Sparkle ATX-400PN (from the late-2000s), which was chock-full of Teapos and CapXons . Am looking to put a yummy mix of NCCs, Panos and Rubys in their place.
Here's the problem I ran into: The 3.3V rail is filtered by a single 4,700uF/10V Teapo... The problem? This thing is only 10mm wide, and a wider (12mm) cap will not fit! I've searched the "big three" shops (Mouser, Digikey, Newark/Farnell) and all the 4,700uF/10V I found were at least 12mm wide. The closests matches I could find in 10mm were 3,300uF/10V and 4,700uF/6.3V.
So my question is, as the title says: Is it okay to use 6.3V caps on the 3.3V line of a PC PSU? (In fact, I don't recall ever seeing a 6.3V cap on a 3.3V rail; it's always a 10V, just like on the 5V rail.) If not, then would dropping from 4,700uF down to 3,300uF cause issues?
Thanks in advance.
