Recapping Mac SE PSU: 620uf 400v impossible to find

Hi,

I've been looking for on Farnell, Digikey, Mouser, Google, Ebay,... you name it for a 620uf 400v snap-in capacitor ( D=40mm, H=42mm ).

It's in the Sony PSU of the Mac SE series.

I could find a 680uf, 400v snap-in but I don't know if it's a good idea to replace it with this value.

Probably a 10% difference won't hurt however my concern is it might overload the rectifier with higher inrush currents as it's just after it.

Here's a link to the schematics of the SE PSU:

No, its not going to hurt anything, its not a large enough jump and it has TH151, an inrush current limiter. besides it has power factor correction so it will handle the situation as the PFC regulation comes up.
