I have a compaq board, and that's about all the compaq left of my presario 5320US. I have a new 350 watt power supply. The **** thing isn't getting power from the new power supply. Yes it's plugged it. Yes, it's switched on, etc, etc. My fear is that compaq has their own wiring scheme for the atx connector. Anyone have any help as to where i can find this wiring scheme so that I can switch the pins around correctly?
And no, I'm a poor college kid who can't afford to buy a new board (unless there's a P4 w/ 400fsb board for ubercheap...sdram too...not ddr).

i'm pretty sure that PS is standard...my question to you would be why you purchased a replacement PS. isn;t that thing still under warranty? |

it's not a replacement...it's an upgrade from the 235 that came with it. and no, warrenty's out.
my gut tells me the **** thing's proprietary. comparing the wiring to the wiring specs of the new (and standard) supply, it's a little bit different...and on the compaq plug there is no pin 8 (strange). argh...darn computers. |

Make sure you connect the p4 connector, most of those boards require it.. |

not to split hairs (but since you brought up the definition of 'replacement')...but since you changed the PS, it *is* a replacement...albeit you are upgrading as well.
not able to find any documentation on the compaq site re:the mobo PS connects. |

Yeah, P4 connector connected. Right now i've got my old ps sitting on a garbage can next to the case...looks pretty classy, i should take pictures. So I'm well aware how to plug it in...
And yes, you are correct, it is a replacement. To me, replacement seems to imply that the old one is broken or cant be used, whereas upgrade is to make it better than the current (and still usable) state. The english language just has too many different words  |

if the PS is incompatible...my sympathies
try calling compaq support or email them for more info. if they do indeed use a proprietary PS, you might want to consider a replacement mobo. p4 mobo's are fairly inexpensive...is your case a standard atx? |

also, try clearing the cmos and see if it boots up afterwards. |

You can almost rest assured that Compaq isn't like Dell, who rewires their PS's because it's "better" than the ATX standard. And if they did, your PC would be dead because of incorrect voltages going to the wrong places in your computer.
A couple things that could be preventing your PC from working are the P4 connector, a short, a dead power supply (try plugging in your old one; if it works... guess what!) Since you didn't take the mobo out I'm assuming, it's probably not anything to do with that.
Experiment, because it's only 200+ volts and however many amps, right? |

Compaq doesn't use standard connectors.
My friends tried to insert a compaq mobo to a new case and nooo-o, the power cords just wouldn't fit on the mobo.
