Title: A4000 PSU Capacitor List
Post by: rkidd7952 on September 22, 2015, 02:19:03 PM

I saw a request in another thread for a list of capacitors in the A4000 (desktop) PSU.  Here's the worksheet I came up with while preparing to recap the Lite-on supply in my A4000D.

I don't know if this applies to all Lite-on PSUs, and there's at least one other PSU model (skynet).  I recommend checking a couple locations on your PSU before ordering replacements.
