Actually i am working with True 380S right now, and on the secondary there is a 1µF 50V non polar Fuhjyyu cap. But the slot it's in is polarized.
I think it'd be okay?
The rest of the Fuhjyyu's are burnt, with most in the 5VSB area reading over 40Ω of ESR.
And the 5VSB was reading 8.3V

Wait a second - aren't you asking the same thing that Pentium asked two years before?

Anyway, I already mentioned that I couldn't think of a part of a PSU that would require a bipolar, but another alternative is to use ceramic capacitors for the low values (up to 4.7μF or so at a 50V rating). (The reason they didn't use ceramic capacitors there in the first place was because they cost more than the same-value electrolytic, but on the plus side, they have no electrolyte to dry out.)

I think GP cap would be OK in there. Most of the new low-ESR cap series do not go as low as 1 uF so I start with 2.2 uF KY. Smaller are GP (older VZ stock, newer is KMG).

If you need some caps for it just drop me a message
