Picking caps for Antec SU-380

[ajdrenter]

In my search for a proper 5v heavy ATX power supply, I selected an old Antec SU-380 that I've had in storage for a long time. Opening the power supply reveals a couple bulged capacitors. I removed all the caps and made a map for myself. I found the datasheet for the PCE TUR series in this thread:
https://www.badcaps.net/forum/showthread.php?t=14159
It says these are general purpose, so I assume I can replace them with any general purpose capacitors, but I don't really know anything about power supply circuits or reading capacitor datasheets. Despite this, I've been shopping for replacements:

I've been following recommendations in this thread for replacing the OST RLS series:
https://www.badcaps.net/forum/showthread.php?t=14433
Some of the series mentioned there have had a limited selection or availability in regards to size and capacitance.

I've linked the caps I've picked out so far, but I'm wondering if somebody with more knowledge can give me some advice on what to buy.

Re: Picking caps for Antec SU-380

When it comes to power supplies, one of the most important things to consider is the ripple current. Look at the datasheets, make sure the ripple current matches or is bigger than the cap you're replacing it with (but not crazy too high). There is another factor called ESR but it usually does not apply to PSU's. The caps for them are sometimes listed as for power supplies.

I did this for an antec basiq 380 some years ago it worked great

I have pictures somewhere. Also usually if you don't see the mains (400v) bulging you usually don't need to replace it

Re: Picking caps for Antec SU-380

Thanks for the advice. I ended up ordering mostly Panasonic FR-A series to replace the OST RLS, and I ordered both general purpose and low ESR equivalents for the few general purpose PCE TUR caps. Is there any reason I shouldn't replace those with low ESR caps?

Re: Picking caps for Antec SU-380

i only use low-esr caps.
for small ones i use whatever is cheapest - usually FR's
large caps i'v used FC and FK in the past.

Re: Picking caps for Antec SU-380

I wasn't able to find a low-ESR cap for the primary, but I did buy a Nichicon LGU cap (LGU2G221MELB). I'm not sure it's a good replacement for the Hitachi HU4 that was in there already though, so I could just put that one back. I'm going to attach the datasheets here if anyone can give me an idea.

the high voltage caps you want to try to get 105' temp rated with a long lifespan

Re: Picking caps for Antec SU-380

The Nichicon LGU should be just fine as a replacement for the Hitachi prinary capacitors.
