As the title states I have an OCZ PSU which is not working due to what I suspect are some bad CapXon capacitors. This unit came from my home server which I had not turned on for roughly a year now (though it did work just fine when I shut it down last). Cleaned out all the dust and whatnot inside and went to turn it on, nothing, spent about an hour removing everything to bench test, nothing. Looked through the PSU fan grill and sure enough the one capacitor I can see has some yellow crust on top. Crap, just wasted an hour.
Anyway, strip it apart to find that there are a few capacitors swollen or with yellow crust on top, all of which are CapXon 2200 microfarad 6.3V capacitors.
Relevent specs pulled from CapXon spec sheet are as follows
Capacitance: 2200uF
Voltage: 6.3V
Size: 10x25mm
Ripple: 1470 mA, RMS @105C 100kHz
Impedance: 0.95 Ohm = 95 mOhm @105C
Lead Spacing: 5mm
Temperature Rating: 105C
Since I cannot find an exact replacement I was wondering what I would be able to get away with. I can easily find the same Capacitance, Voltage, and size but most of the ones I find have more ripple, less impedance, or both.
Here is the actual spec sheet.
