an old dell power supply I have does have 2200uf 16v 105 capacitors I could use. Just have to ask why higher voltage would be okay? Being cautious is all. Also, thank you very much!
That is already a fairly tall height to diameter ratio capacitor, so the 16V cap is probably larger diameter, and may also have a wider lead spacing, 3.5mm vs 5.0mm. Since it is an older (aged) PSU, if it is not larger diameter, it's probably not a high quality capacitor. One trademark of poor quality caps that historically proved to be failure prone, was too high a capacitance value for the can size relative to higher quality major (Japanese, etc instead of Chinese) brands.
Regardless, you really don't want to use a capacitor out of an old power supply. Output filter caps in switching PSU like these have a hard life which is why it failed, so you should get a very low ESR, new capacitor, and consider replacing all the output filter caps while you're at it, so it doesn't just have a similar failure next time on the 12V rail rather than 5V or 3V.
BTW, you don't even need a 10V cap. As mentioned above this is 5V or 3V rail so a 6.3V cap would work, then get 16V replacements for those on the 12V rail.
If located in the US, I'd pick out of these suggestions on the following link based on diameter, lead spacing, and next highest voltage over the power rail it filters (of course there are many major brands of very low ESR caps that would be suitable). Digikey has no minimum order limit and reasonable USPS shipping rates, but any major discrete electronics supply house would carry something suitable in a top tier brand.

On a side note, I never realized I could paste a picture from my windows clipboard into a post! I accidentally did that intending to post the above link, and of course them removed it because not appropriate to the topic.
