Re: Ultra X3 ULT-XC600W Teardown & Repair

Ultra X3 is back in service.. Thanks for the help everybody.. It hasn't smoked or eletrocuted me yet so I guess that is a good sign..

I was going to place a heatsink on the T-220 but it has a resistor directly underneath.. If it dies in the future I'll see about doing something then.. Maybe custom (shortened) heasink.. Just tested sleep mode and everything works..

I replaced the following caps.. Partial recap..


Teapo 420V 390uF (Unchanged)
2 x JunFu WG 105C 25V 220uF >>> 2 x Rubycon YXF 25V 220uF 105C (5000hr)
3 x Teapo SC 105C 16V 3300uF >>> Samxon RS 16V 3300uF 105C
4 x JunFu WG 105C 10V 3300uF >>> Samxon RS 16V 3300uF 105C
1 x Teapo SC 105FC 16v 1500uF (Bulged) >>> Nichichon HD 16V 1500uF
1 x Teapo SC 105C 6.3V 470uF >>> NCC KY 6.3V 470uF
All Low value caps (Unchanged)

Hope these caps were ok.. Everything is working so I guess that is a plus.. Time for

It's usually better to measure voltage with multimeter, MoBo voltage sensors may be very inaccurate.

Re: Ultra X3 ULT-XC600W Teardown & Repair

Usually I do.. I was wanting to get this back in service and jumped thegun.. Looks like I have a short near PS_on or the -12v line to modular plate is causing problems.. Just had a random shutoff.. Time to tear this back out.. Im hoping a cracked solder lead when I put the board back in..

Power button doesn't want to work anymore.. Does anybody have advice for clip on heatsinks for T-220?

Redid some solder connections and it powered up.. Stressing it now.. I noticed initially the power button worked good.. Then occasionally had problems in the morning.. Then stopped.. Came on first time after the quick redo.. did pson.. 5v and the grey signal wire.. The -12v to the modular plate is iffy but its holding well.. I believe the T220 if this is the part is labelled Q1 or O1 on the board.. If I were to replace this would a small clip-on heatsink work with a resistor directly underneath?
