Need Help, First time Ordering a Cap for a PSU for a Computer

[Xtremepayne]

A freind at work recently had a PSU go on her and Best Buy replaced it with a new one. I asked her for the old supply to see if I could fix it. I found a bad capacitor in it. I have since got it removed and here is the all the information off the side of it
Teapo 2200uf 10v sj105c 04/08 T3

I have never ordered a capacitor but I have been reading here about making sure to order low ESR Capacitors.

The Power Supply is a Bestec ATX0300D5WC Rev. A

I am repairing for the experience of it as I have never repaired a PSU before. What I am looking for help on is how to order thru Digi-Key, its kinda confusing. I wanted to learn because from what I have read here I get better quality if I order online.
I await your wisdom.

I know it often runs together but the SJ isn't supposed be part of the 105C.

That is a Teapo SJ series but it's not likely the only cap that's on it's way out.

ESR = .021 ohms [Want the same or a little less. - Without going nuts.]
Ripple = 2360 mA [Want the same or more. - Can go nuts.]
13x20mm

---
Standard Procedure:
---
List the caps.
Include - Make / Series / uF / Volts / Diameter / Approximate Length
From that I/we/you can find the Ripple and ESR specs.
-
While you are at it make a map of the PCB and mark where all the caps are including their polarity. [Cap Map]
It will come in handy later when you forget what came from where or which side of some cap was negative.
On PSU's it's easier if you draw it life-size.

- Tip -
Lacking a tiny inspection mirror. [Which are near impossible to find small enough.]
... For those buggers you can't read the back of take a butter, steak, or exacto knife and polish the 2" of blade nearest the tip up all nice and pretty with some gritty toothpaste. Then use it for a mirror.

A small flashlight helps too.
And an artist paint brush [or cue-tips sometimes] to wipe dust off the markings.

When you search at digikey, once you are at the caps search screen...

Select:
"In Stock"
"+/-20%"
"Radial, Can"
And then using the "Ctrl" key select all the Operating Temps that end in 105C.
- Then click "Apply Filters"
---
That will get rid of like 90% of the caps you don't want to look at.
