Somebody linked this shop in this thread.
Now I am little confused. Should I use 4.7µF with 16V or with 50V?
That has exactly what you need in one package, one price, but nobody could vouch for the quality. You'll likely need to buy at least two cap kits to get all the values elsewhere.
A small 4.7µF capacitor is likely gonna have a high breakdown voltage of 50V, but anyhow, 16V would still be safe. The Turbo Duo operates at 5V max past the voltage regulator where 10V comes in from the unregulated power supply (so it's probably like ~12.5V)... So, since the motherboard operates at 5V, 16V max caps are perfectly safe and way above that.
When you start getting lower than 10µF to 5µF to 1µF and below (1000pF) as far as capacitance goes, you start getting into the ranges that ceramic capacitors support and they can handle 50V to 250V, while still being small, etc. So, that's why, even though it's aluminum, it can handle 50V max... At 22µF and above, something like that, the the breakdown voltage that the cap can handle goes down, but for more money and at the expense of a bigger size, you can still get them with higher rated breakdown voltages, etc.
And I can't find anywhere (within Europe) Panasonic caps with 22µF/16V with a lifetime of 5000h-10000h, only 22µF/25V with 1000h-5000h lifetime or 22µF/50V with a lifetime of 5000h-10000h.
I want them to last as long as possible. Any recommendations?
The higher the max breakdown voltage is, the more expensive and bigger the capacitor will be. As long as it says 22µF, you can use it just fine! So get the expensive 22µF/50V ones if you wanna spend the money and want a high lifetime rating.
Basically, the rule for replacing is: make sure the capacitance value matches exactly, and that the voltage rating is at least twice what the circuit operates at. And simply know that the higher the max breakdown voltage is, the more expensive and bigger that the capacitor will be, as I said, but that it'll still work fine and likely just last longer...
