HP proprietary motherboard and power supply problems...

This is why specialized, proprietary systems are a bad idea.

Trying to change a blown power supply in an HP desktop machine results in ridiculous expenses, or a whole lot of futzing around trying to get things to work, because this machine, like a number of HP models, does not use standard parts. They look standard, but they're just different enough to cause problems.

@pooooo52 New, or used? Also, keep in mind that this video was posted 2 years ago. Things change a lot in the industry in that time.

Hi there. I've been doing almost exactly the same thing, but transferring the d530s into a compaq case. I was able to remove the cpu heatsink compartment from the compaq, and pop it into the scewholes in the d530, and securing it with the little plastic tension pins that fit into the corner holes. I am curious how you would have sorted out the front I/O pinouts tho, as they are attached to the mobo with a single plug, rather than separate ones for led/pwr on. Cheers from nz :)

All is not lost, get your multimeter and soldering iron out ;)

@cbiltcliffe I don't have a multimeter, but I am sure I can borrow one. Thanks for the suggestion and the help.

@fortyaider Wow. They're pretty rare. I might have seen one or two of them in years. Couldn't tell you the pinout offhand, or where to find an adapter, either.

If you've got a multimeter, you can measure voltages off the PSU, which will tell you if something's missing, or badly out of spec. A bit more work, but cheaper than an adapter, provided you've already got the meter.

@cbiltcliffe I don't have a digital camera, or else I would send you a pic. The type of connector is called a Micro-Fit ATX plug/connector. I might order an adapter so I can plug in a regular PSU in to the MB and make sure it's not the PSU that is bad. I have a feeling the PSU is good but the motherboard is toast.

[cbiltcliffe]

@fortyaider Smaller than the older 20 pin ATX? Weird. But not really surprising.

Could you get a photo of it and send it to me? I'll PM you my email address if you can do that.

You could always rig up an adapter to go from standard ATX to HP weirdo connector. I think the voltages should all be the same, provided there isn't some strange "ThisIsTheCorrectProprietaryPS­U" signal line.

That's assuming you're comfortable with wiring something up.

[cbiltcliffe]

@tubewinkle Exactly. I mention that in either this video, or another one I have where I'm swapping a Dell motherboard into a generic case due to the exact same problem.

[fortyaider]

@cbiltcliffe The motherboard on the HP slimline I have doesn't have a standard atx connector. It uses a propritary(sp) connector, it's smaller than a regualr atx connector.

[cbiltcliffe]

@fortyaider The connector on this one is standard ATX. You can plug a standard power supply in to test it, but you'll have to run it with the cover open.

Check the connector wiring between both PSUs before plugging in, as they sometimes change things just to be annoying. As long as they're the same, testing is simple.
