Smoked another PSU....Grrrrrr!!!!!!!!!!!!
OK, this is the 2nd one I've done this to, so I need a better method for...........
Plugging-in a PSU!
I did it to an e-machines too at work.......(thank goodness I'm a good storyteller so our network guy just ordered another proprietary e-machines psu). This morning it was my daughter's computer. It happened the same way both times. Plug the power-cord in & the psu fries.
This morning's event took a little longer, 'cuz I was in the room a few seconds after I plugged it in & didn't see/smell anything. Then my wife called me several minutes later while I was on the road & said the room smelled like smoke. I knew EXACTLY what it was. Had her try to unplug/replug & this time "FLASH"...........ahhhh.......chestnuts roasting on an open PSU flash! Oh well......anybody got a suggestion for keeping this from happening?? I move computers around too much to leave 'em plugged in all the time. TIA

ummm don't get emachines ???" If you kill a man you're a murderer ..... Kill many and you're a conquerer ....... Kill them all ... your a GOD...."

This one ain't an e-machine ya' metal-head. It's a generic, never-been-touched by Fortune 500 hands, homebuilt!!! har har har!!!
What the heck are ya' doin' up at this hour anyway??? <g>

Doesn't make any sense. I do it the same way and never have smoke checked a PSU. Maybe make sure the switch on the PSU is in the off position first?“MICROSOFT: Where do you want to go today? APPLE: Where do you want to go tomorrow? LINUX: Are you coming or what?”

Maybe an UPS attached to each machine would smooth things out?

since were on the subject off cleaning computers you know those pressurized air cans can you use those on the mother board
December 15th, 2003, 01:31 PM #8
you can use the cans or any dry air source.Hard Sayin Not Knowin

Pressurized air can.......yes. (Though a nice 125psi 20-gallon air compressor works a bit better.......he he he!
For those who have never had this happen to them.......I do know of one "sure fire" (no pun intended...har har) way to keep it from happening.
Method: Immediately after plugging in the PSU, hit the powerswitch so that the psu cycles the power properly through the mobo, etc. When doing this, it seems to inhibit "smoking psu" syndrome!!!
As for flipping the switch on the back, I don't think that has any bearing on whether the psu smokes due to plug-in, rather it controls "output" power to mobo, periphs, etc......(imho)

I use a 125#air compressor with a breathing air filter.Hard Sayin Not Knowin
December 15th, 2003, 01:50 PM #11
Ya, a filter can be good if your computer's growin' a full-beard inside.......LOL!!!!!!!!!!

so is the moral of the story to blow out the power supply more than once every 3 years ?" If you kill a man you're a murderer ..... Kill many and you're a conquerer ....... Kill them all ... your a GOD...."

i wouldnt use a regular air compressor to blow out a pc, those things have moisture and condensation build up...be safe and only use the pressurized cans of airI'd rather be driving a titelist

i think thats why he uses a breathing filter to cut down the pressure
December 15th, 2003, 02:24 PM #16so is the moral of the story to blow out the power supply more than once every 3 years ?
No.........we must resist the temptation to do this!!! What you do is you go 4 or 5 years, then bring the computer to the kitchen table & don't shoot the air in 'til PRECISELY when your wife asks what the $%@#$ you think you're doing!! That's about the same time it looks like somebody got a haircut all over the kitchen floor!!!! he he he!!
As for can vs. air compressor?..........(chanting briskly rises above the wind)......."a/c.........a/c...........a/c...........a/c............a/c!!!!!!!!!
December 15th, 2003, 11:50 PM #17Beware as its possible to accidentally spin a fan WAY beyond its RPM limit with 125 lbs of airpressure---make sure you have a watertrap on it as well---dont wanna spray oil/water around inside your case...
I have an inline filter installed on my blowgun, which can be found at any auto paint store, because I use it for cleaning computers and other delicate parts.What did a tornado sound like before freight trains were invented?

only a dryer will remove the moisture
December 16th, 2003, 12:26 AM #19
are you suggesting we toss our comps in the dryer and spin them around? that would probably make stuff fall out of the sockets and whatnot, also prepare for some serious denting of the case
December 18th, 2003, 06:18 PM #20
Uh oooh!!! Put in a nice new 500W psu & no-go!!
I don't see any burning anywhere else on the mobo or anything.. What might have happened?? Could I have fried the power switch?? Something from the mobo ATX connector to the power switch header that could have fried??
