I would like to splice in a computer power supply to see if the the time capsule electronics are still functional--the power supply is dead.
Questa è una buona domanda?

Dan Gardner, I used an image from ifixit. The voltages are
Pin 1- 5v
Pin 2- 5v
Pin 3- Gnd
Pin 4- Gnd
Pin 5- Gnd
Pin 6- 5v
and the image should tell the rest of the story. . BTW have you tried to fix yours. You do know that some of them only have the usual failing capacitor issue. May be a cheaper fix. Hope this helps, good luck.

The Time Capsule is notorious for blowing capacitors. It traps the heat and tends to kill good caps like Nichicon and Ruycon like a cheapo capacitor in a Gateway monitor. You can recap it but it will just do it again. I'd still do it and try anyway, just in case it lasts. If it doesn't die again so soon, then it will probably be fine. If not, then don't try again.
Also, don't be that one guy who changes the bad caps out and leaves the ones that are fine in, and blames Apple for it. Change them all out, even if they work. The ones that are intact always fail next.
However, doing this is VERY risky. You need to drain the power supply for a few days and then find a way to dump the extra power that's left, especially for the filter cap. The small caps will drain easily and not bite but the filter cap will get you good. It's possible, but I really don't recommend this unless you do your homework or know how. This isn't for the feint of heart.
Here's a recap kit if you think you're up to rebuilding the old power supply
If my advice is tough, it's because you can't screw around with this.
I am not responsible for the results, either.

nick, nice little Wicki, but transformers do not hold a charge, it's the caps that do. Those are the once you want to be careful off:)
The tolerance is not 50uF but a percentage of the capacitance the caps. Power supply electrolytic capacitors have a tolerance of up to 100% higher, so you can replace a capacitor with another capacitor as long the replacement is equal or higher in uFs and voltage
I can say from experience that leaving the time capsule out of mind for a few days will NOT drain the capacitors. They hold their charge for a long time. Get a low ohm resistor between a pair of pliers and hold it across the contacts of each of the capacitors. Make sure they are drained because it does hurt to be zapped.
