Default Re: DFI-ITOX G4S600-B with Chemicon KZGs - compatible caps?

The lifetime rating on the Panasonic FR is meaningless in this application, in the sense that if the Panasonic FR capacitor is meant to withstand all the ripple of an ultra-low ESR cap, it's lifetime rating wll probably be equal to or less than the ultra-low ESR cap. Moreso, FR has a lower ripple rating (not to mention that it will also get hotter because of its higher ESR), so it could last significantly less time.

You should use HM/HN/HZ. You mentioned you were looking at Digikey. They may or may not have what you need in an electrolytic cap. You might try doing a polymer re-cap.

Since this machine seems to be from 2006, it's robably worthwhile to have a look inside the PSU to check if the caps in there are OK. That way, you can order both the motherboard and PSU caps together and save on shipping.
