Re: imac G5 PSU cap kit
More news:
As well as the obvious physical damage suffered by all four 6.3V capacitors in the group I found that the 35V 330uF capacitor was down to around half of what it should be (this is the one below the copper heat sink and may have been running rather hot as a result)
I don't have an ESR meter, but if I were to purchase an ESR meter it would probably be this one: [url]http://www.anatekcorp.com/testequipment/atlasesr60.htm[/url]Re: imac G5 PSU cap kit<br />

Re: imac G5 PSU cap kit
Just to report that I ordered
3 x Samxon GC 1000uF 6.3V D8 x 14mm
2 x Samxon GC 2200uF 10V D10 x 25mm
1 x Samxon GT 1200uF 16V D10 x 25mm
1 x Samxon GA 3300uF 6.3V D10 x 25mm (original was 4700uF)
1 x Samxon KM 1000uF 35V D12.5 x 20mm
1 x Samxon GF 330uF 35V D10 x 16mm
even thought only the 6.3V capacitors showed damage.
Repaired two power supplies, and both machines are working fine....Last edited by shiekh@dinecollege.edu; 12-06-2008, 02:30 PM.Leave a comment:

Re: imac G5 PSU cap kit
Thanks, I realized that; it was just that when I didn't see the 16V Cap (my fault), I could not figure what the 12V was riding.Leave a comment:

Correction, there is also a 16V capLeave a comment:

Re: imac G5 PSU cap kit
I'm way confused; the iMac G5 power supply is:
3.3V 3.1A
5.1V 9.6A
12.0V 9.2A
24.0Vsb 0.33A
5.1Vsb 1.5A
but the caps are 6.3V, 10V and 35V
how does this work? what holds the 12V for instance (which is by far the greatest power line)Leave a comment:
