Replacing Capacitors In My Xbox

The Xbox is notorious for a failing capacitor known as the clock capacitor. When it fails it will leak at the bottom, spilling it’s corrosive electrolyte all over the motherboard which will destroy the solder mask and the frail traces beneath it.

The clock capacitor from my unit.
This is the clock capacitor from my unit. I’m glad I didn’t postpone this restoration more than I already had.

Due to this ticking time bomb and the looming capacitor plague I decided to recap my Xbox. Not just the clock capacitor or the other usual suspects, all of them. Every electrolytic capacitor that is. The caps in the power supply too.

My Xbox is a PAL unit with a revision 1.4 motherboard and as it turns out it’s the most common revision. It’s my first time recapping this model so I decided to document the capacitors very carefully. I’ve found other documentation online but it hasn’t been as meticulous as mine so I thought I’d share my findings as well.

The power supply in my unit is a Delta DPSN-96BP. I’m not aware of how common it is but I’ve included my documentation for that as well.

Warning: I would guess that the motherboard will have the same capacitors regardless of region as long as it’s the same revision but I’m quite certain the power supply unit will have different capacitors depending on if you live in a 240V or 120V country.

Note: The values in the column Capacitor map to a value in the column with the same name in the BOM tables.

Note: The physical dimensions, i.e. the diameter and the length, are inexact but for our racapping purposes accurate enough.

Bill of Materials

If you want to order capacitors I made these BOMs with the relevant information you need.

Motherboard

Capacitor ⌀ (mm) L (mm) Capacitance Voltage Count
1 8.2 12.4 1F 2.7 1
2 5.3 11.4 22µF 25 13
3 10 23.2 3300µF 6.3 3
4 12.7 24.8 3300µF 10 2
5 6.2 11.4 100µF 25 7

8 6.3 4.7 47µF 16 1
9 4 5.5 10µF 16 5

That makes 36 in total.
