Check out www.thecapking.com<http://www.thecapking.com> . I tried sourcing caps on my own and a lot of suppliers were out of stock. This guy had replacements that would work. It's not just the voltage and temp rating. You need to match the type, particularly in power supplies and monitors. They can have bi-polar and high-frequency specs that you have to match up otherwise they will pop.

Recently, I had a customer Dell monitor fail. Inspection revealed swollen capacitors in the power supply. My son has been seeing and replacing the same kind of swollen capacitors in Flat panel television power supplies with a good success rate. My guess is that this is a capacitor manufacturing issue (low quality or NO quality) and these capacitors are used in power supplies of many different products. They run for a while but fail prematurely, taking out the device they power. I'm trying to get a capacitor order together for next week so we can put a few devices back into service. We're going to try some capacitors with a slightly higher voltage rating and the same microfarad rating and see if we can get a little better service time out of them. Many of the TVs my son is seeing are less than a year old.

I'm trying to go through emails, but I honestly can't recall off the top of my head what the model number was (they were all the same). -----Original Message----- From: Matthew W.

We're having a very large failure rate of computer power supplies in 2 of our brand new labs. These are 2 labs of 32 computers each... one lab is Dell Optiplex 390 SFFs, the other is Dell Optiplex 790 SFFs. I think they use the exact same PS. Issues are either A) No power and no lights, B) Blinking yellow power lights and won't turn on, or C) *Poof* smoke. We have 8 failures in the past month out of 64 computers. I'm just curious if anybody else on the list is seeing similar failures for recent SFF dells... Sales rep contacted, I'm awaiting response. --Matt Ross Ephrata School District ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
