The SFF power supplies in the Optiplex 390s and 790s are relativly easy to replace, thankfully. 3 screws in the back, removing the drive cages (all screwless) and you're good.

OUCH!!!!! We are in the process of installing nearly 100 Optiplex 990's here. Is it very easy to replace the power supplies in your units? On our Precision Work Stations, we had to pull the motherboard to get to all the power supply wires. (Fortunately, we had become quite good at that as I think our motherboard failure rate on the PWS-series was something over 60%.) -- richard "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] 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 ~ 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
