In-Win IP-P350AJ2-0 - Replace 200v primaries with 160v?

[mockingbird]

I've got this PSU model and I want to replace the OST primaries with these, because I can't find 200V in 18mm. These are connected in parallel, so 320V should be enough for 220v countries, right?

Also, does anyone know if 0.3A is sufficient on the -5V rail for ISA slots, specifically, if three ISA slots were populated, or should I go for something with 1 amp?

Thanks (Sorry for the blurry pictures).

160x2= 320
rectified 230 is more than that!


maybe if you reduce it to 470uf you can find a fit.

Connecting the caps in parallel will give 1360 uf at 160 Volts. In series it will give 340 uf at 320 Volts.

It's 325.22V, correct? Yea, I can get it in 560uF, I think I'll do that.

"These are connected in parallel" Do you actually mean these two 200V rating caps are in series?
What ever you do make sure the ratings is 400V or higher. That looks like bridge drive setup.

Oops, yes, I meant to say they're connected in series.

So stj is correct, because after rectification the voltage would be 325 volts. I'm gonna go with 200V 560uF caps instead.
