Please confirm a question for me

[Quintz]

I'm working on my boss' computer (e-machines W1800) it would not start up at all, no power to any fans or lights so I have found that the power supply has gone bad (using this test method http://www.duxcw.com/dcforum/DCForumID3/447.html ) so I feel it needs replaced. Would there be any reason that I'm wrong about replacing this PSU and do I need to replace it with an exact model, or will any 250w PSU work?

edit:If curious, here is the PSU that was in the computer http://www.power-on.com/atx12vem250bt.html#conn

I can't say for sure whether the supply is bad or not, but as for your other questions, yes, the pinout of your current supply looks to be standard atx (some prebuilts use a different wiring arrangement), so yeah, most any aftermarket supply of at least 250W should work. Try to get a good brand though, something like Enermax, Enlight, Antec, Sparkle, or PC Power & Cooling. 250W supplies by good name companies are getting harder to find though....Sparkle might still make one.....I can still find some 300W ones though, and those would do fine as well. Maybe something like one of the following.

If it's not the PSU, what should I check?

thanks for the info.

Careful! That's a proprietary PSU. A standard one won't work in there.

Did you actually jumper the green wire to ground ? If so did you measure the voltages with a DVM? what did you see ? if it is bad this is a good supply and reasonable.

If the power supply is good ? then you have another faulty component...
Try disconnecting all drives and anything but the MB. Something could be loading the supply down or the MB good be bad..

using that above test, I got nothing out of the PSU, I tested the cord with another PSU using the above test and it worked.

Blue, I was afraid of the proprietary PSU... that's why I thought I'd ask in here before ordering an replacement.

[Al Pollock]

Hey Blue how do they make a pripriortary PS ???special plug's ???I would like to know...........

The motherboard plug would be the same dimensions but the wiring will be different from a standard ATX wiring.

OOOOH ! thanks Cricket

[Al Pollock]

But that could be fixed with a pin pusher and just moving pins around

[Cricket]

I guess that would work...never tried it before.

That's an idea, but you better make sure you do it right.

Would you care to elaborate on how you came to that decision, blue? If his link to which power supply he has is correct, the wiring pinout is the exact same voltages, colors, and everything as a standard atx. That being the case, why would it be proprietary?

[Quintz]

If I could get something other then what was listed, it would save me some money. Guess it's either paying more for an exact replacement, or roll the dice for an off name. Since it's my boss', will go with the exact replacement. Thanks for the help all, very much appreciated.

Take a look at the link I posted. I plugged in his model number and it came up with that power supply, it's listed a proprietary 20 pin ATX power connector.

If you've got another standard power supply to compare with, you could double check. Or google around, and find the pin definitions just to confirm.

Yeah, I saw your link said the connector is proprietary too. I did already look up the pin layout before my first reply and that's why I recommended the other supplies, because the pinout for that supply is the exact same as a standard atx supply. So either they're labeling it as a proprietary supply when its not or the pinout is wrong and it is proprietary, one of the two. Because they're saying its proprietary but the pinout says it's standard atx. Don't know which.

Here's one I just used in an eMachines. I'm thinkin' this proprietary connector issue at affordable surplus isn't special at all. I've swapped standard ATX psu's in emachine's that are on that list without a problem. As long as the wire colors are in the same arrangement on both connectors, I think you're good to go.

I got the one that was posted in my link from power-on..arriving today. Thanks for the help all. :-)
