| 90338 | 2002-10-17 18:54:00 | I have a bunch of Compaq p100 machines with faulty psu's. These psu's have one 9 pin 9 wire plug and one 7 pin 6 wire plug going to the m/b. The psu also mentions supplying 3.4v as well as the normal 5 and 12 volts. They are a atx type setup regarding the on/off switch but an at case. Part number 213928-001. Can they be replaced with a standard at supply(with mods if needed) or does anyone know of a source of replacements??. Thanks |

| 90339 | 2002-10-17 19:01:00 | Ah branded computers. I imagine compact did this because an AT case is smaller, and its cool to be small. I would see no problem with why you couldn't replace the ATX PSU with an AT one. But remember the m/boards themselves would have to take AT power supply |

| 90340 | 2002-10-17 19:57:00 | Ok, it is the 3.4v thing that I am worried about. It is not a problem to fit the psu into the case and make the switch work etc. Typical Compaq, why do they do these things?? Mabey I will have a play and if i fry a m/b i allways have 4 spare! |

| 90341 | 2002-10-17 20:14:00 | Hi RMCH I did the reverse & fitted a Compaq PSU into a standard clone computer. I found that the two plugs were directly equivalent to the normal single large PSU plug so I just cut off the wires and spliced then onto the plug off an old dud PSU. I had to do this because the Compaq supply had very short leads and they had to be extended to reach my MB. The reverse installation that you are planning would probably work without modification because the leads would be longer and the single plug should go where the other two went. I don't know what the 3.4 volt oddity is for (any chance it is for charging a nicad cmos battery?) but it could be the PSG signal (power supply good). That just tells the computer that the PSU has come up and since my computer didn't need it I left it unconnected. In the reverse case the PSG supply can be picked up off any +5volt line. I'd do a google on the 3.4volt if you are concerned but otherwise patch in a PSU and see if everything works without it. Cheers Billy 8-{) |

As I have warned a lot of ppl do not get branded PC.. and this is one of the reason.. not only Compaq, HP is the same .. well .. they are practically the same now :D They do this so they can rip you off when yr PSU is dead since u can't use a generic one, and they will sell you THEIR version of PSU ranging from $150 - $300 depends on model .. Heck! I could get a certified reputable 400W dual fan PSU for $110 ... |
