Power Supply on MDD Dual 1G Same as Quicksilver?

Can anybody tell me if the power supplys are interchangeable.
Thanks
Enio

Hi-
No, they are not.
MDD's only work with MDD PSU's.
You can see wiring differences here:

Power supply in MDD dual 867 shot?

I arrived home today to find that my Dual 867 G4 was powered down, though I had left it on when I left this afternoon. Not only that, but it won't turn on at all - the power button doesn't light up, there's no spinning of the disks, no chime, nothing. I've unplugged and re-plugged the power cord, switched out surge protectors, plugged it directly into the wall socket - no dice. One thing I did notice, though, is that when I plugged the power cord into the back of the G4 after I had disconnected it, I hear a very faint and periodic short noise, maybe every one second, from the back of the G4. Almost like a short buzzing noise, but too quiet and brief to really be called that.
Does this sound like the power supply is shot? Like it's shorted or burnt out in some way? Thankfully I have two iBooks to use in the meantime, but most of my daily used files and such are on the 4 hard drives in the G4, and there's no space for them (particularly my music) on either of these laptops.
If I do need a new powersupply, does anyone have recommendations for sources? It seems sellers on ebay want the sell them for over $100.
Thanks,
Anthony

Hi,
Yes, that does sound like a power supply issue. It could also be a bad CPU card, or even the motherboard. To isolate the problem, I'd take out the power supply and measure the voltages across the different pairs of wires in the plug that feeds the motherboard. If the voltages don't equal what they should, as per the G4 MDD service manual, then you're in the market for a new power supply. And yes, the ones on eBay will go for 100-150 or so. Make sure it's stated to come from a working system. Untested power supplies could be dead ones from a similar dead machines.
If the power supply voltages are OK, then to isolate whether or not the motherboard, or CPU card is bad will require a spare motherboard, or CPU card, to swap with yours.
Sources for new, or rebuilt, power supplies include WeLoveMacs , DVwarehouse, HarCoreMacs , among many others.
Here is a good set of pictures and step-by-step instructions on taking the MDD power supply apart.
In my case, I had a spare motherboard and power supply to test with. The machine, which I got cheap off of eBay because it didn't work, did not turn on at all. Swapping first the Power supply with a good one didn't bring it back to life. Turns out the CPU card and the power supply were both bad. Once both were replaced, the MDD machine has worked fine.
Good luck!

Power Supply for G4 Dual 1.42 MDD

I am needing a new power supply for my Dual 1.42 G4 MDD and need to know what models I can replace mine with.
Thanks

Hello! Try looking HERE. Tom

Obvious power issue effecting all back plane jks. Popping HOURLY (clocked) thru speakers, lites up lamp on doc scanner. Has blown power supply once. "Genius" diag NTF twice B4 power supply blew. Still have same trouble. I made very CLEAR to Genius Bar that it was a hardware issue after they continued to trouble shoot software. I was referred to tier 2 who told me they only worked on SOFTWARE. Does anyone know a more qualified shop who can fix an OBVIOUS mother board issue tracing back to the power supply? I had the same issue with a 20" with 7 visits & had to literally take a video of the trouble before they could figure out the trouble was the video card. From reading the sheer number of posts of the same trouble descriptions going back to 2007, it's all too obvious the path to MSFT is being taken.

Want references for using ATX power supply with MDD.

There are references all over the place to adapting an ATX power supply for a MDD/FW800. But it would be nice to have links to as many useful ones as possible in one thread -- this one -- without too much superfluous verbiage.
Please post links with brief descriptive comments or, if you have some hard information that's not easily linked to, please post it as concisely as possible. Hopefully, the resulting thread will be useful to many people, and not just to me.

I have a 1st Gen Time Capsule 1tb. It turns on, boots up and turns green for 5-10 mins, but then turns solid orange and then blinks orange. I have removed the hard drive and replaced the power supply . . . still the same problem. Suggestions?

I purchased a used 1st Gen Time Capsule with a 1 tb hard drive.
When I plugged it in and did the initial setup, it worked fine, but gave me a hard drive error. A few minutes later the green light turned solid orange, then blinking orange, then the status light went off. The lights in back stayed on.
I removed the hard drive and rebooted, it turned green for 5-10 minutes then reverted back to a solid orange, blinking orange, then went off.
Next I purchased a remanufactured internal power supply, and installed it (without the hard drive in). It turned green almost immediately. After about 15-20 minutes, I decided to try to install the hard drive again, booted it up, and tried to erase the hard drive with was working properly according to the software. It stopped erasing the disc after about 20 minutes and turned solid orange again, then blinking, then no status light (but back lights were still lit).
I'm a bit flabbergasted at this point, any suggestions on what to do next? I think i've pretty much replaced everything except the logic board, but can't seem to find any information on the symptoms of a logic board malfunction.
Thanks!!!!!!!

A Gen3 is identical board to a Gen4 although they have some differences in firmware and wireless card was updated on every model.. but a Gen3 is substantially faster than Gen1, Gen2 which also have identical boards.
You can with careful shopping get a Gen3 pretty cheap.
Most use a delta power supply which I think is a lot better than the flextronics used in most Gen1/2
You can sell back the parts to ebay.. people still would buy the power supply etc. Even just the case can be useful to a repairer.
But if the board is gone.. it is hard to repair.. not impossible.. but hard.
Gen 3 and Gen 4 are not without faults.
See this page.
https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem s/apple-time-capsule-repair/new-issue-with-a1355-gen-3-tc
I have fixed it a different way.. by using the small converters you can buy in bulk from ebay for $1 each.. KIS3R33 .. they produce 3.3V at 2A peaking at 3A.. amazing.. I keep using them to replace onboard power converters by removing the inductor and simply power directly.. the end result has worked great. You can simply change the resistors around and get any output from 1v to 20v depending on input.
Is it worth doing it .. no of course not.. it will waste many more hours than $50 is worth.. but it is kind of fun that you can actually make things work again.
Here is a pic of the Gen 3 totally powered by me. All onboard power removed.
This was to track down the fault in the Gen3.. but I am kind of pleased that it ended up neat enough and reliable enough to work for more than a year.. the Gen3 still serves as a way to get Netflix via network for a friend running 24/7.
The units supply (from left to right)
1v, 1.1v, 3.3v, 5v, 1.8v
It is feed by 12v supply which is also directly connected to the hard disk.
So it is possible to fix.. !! Only got to be a bit crazy.

E3631A IVI class driver can not enable power supply three channel outputs at same time

Hallo,
with E3631A IVI class driver i am trying to enable all the channels at the same time,The problem is that class driver supports only Channel Switching between three Channel,i find in this Forums this Discussion
http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/E3631A-IVI-class-driver-cannot-enable-power-s...
is it possible to enable all outputs at same time that I modify the source code and recompile the drivers,but it is complicated for me.
Is there a another easy way to solve this problem??
Would appreciate if someone who has worked on it suggest a method appropriately. Thanks!
Note：Labview 2009 sp1

You'll either have to modify yourself, ask the poster in that other thread for it, or use the LabVIEW driver.

Power Mac G4 MDD Dual 1.25 - forbidden sign at bootup/PRAM

Hello everyone,
I am the proud owner of a couple of MMD G4s (the Dual 1.25 & the Dual 1.42).
My dual 1.25 (fresh Leopard install from two weeks ago) is giving me the forbidden sign at startup.
I did use the Leopard Install DVD to repare all the authorizations but it didn't make any difference.
The good news is that if I restart the machine and do a single PRAM reset, the machine boots beautifully into 10.5.8.
However, I'm afraid of damaging the motherboard by always booting with a PRAM reset so I'd like to know if anyone has encountered this issue ?
(maybe the battery is too old ? It's a replacement Newer Tech from OWC from 2 years ago).
Thanks !
Pierre André.

Hi Pierre, it does sound like the Pram Battery, it's life of 4 or so years can be drastically shortened if ever the Mac is without AC power.
Try holding the Option/alt key down at bootup & select the boot drive to se if that works.

Dual 867 kernel panic problems, is it Power supply?

My 4 year ish old dual 867 is acting weird. Started when i installed leopard (prob coincidence though) the other week. It started kernel panicking every night as i normally leave it on, but also any time i left it alone for half an hour. If i left it writing a dvd overnight it wouldnt crash.
I installed on an other drive and didnt install anything but it still crashed, it took 3 attempts to get it to install from the cd as it crashed the first two (kernel panics).
I took it to the only mac store on the island. Very friendly but couldnt reproduce even one crash. Had it for 36 hours, ran tests, no probs, left it on for a while, no crash.
In talking to them it came up that it could be the power cable as id posted on another site the crash log and someone said it was the power supply as hed had the same.
The shop disagreed, but lent me a new cable. No crashes for 3 days. Solved!
Then i installed new ram to try to speed up football manager. Back to crashing every 20 mins. Checked the ram was in okay, and ran remer, memory was fine. Crashing stopped being regular but still intermittent. The guy on the other forum is adamant its the power supply from the crash log but i cant see what says that.
The monitor is an apple adc lcd monitor which has two usb ports that stopped working about 2 months ago.
This is one of the crash logs

P/N for Install discs, G4 MDD, Dual 867

Does anyone know the Apple part numbers for the original discs that came with a Power Mac G4 MDD, Dual 867Mhz? or where to get them?
After reading through the postings here I gather they are a MUST have to be able to boot OS9.
If anyone knows of another way please let me know.
Thanks,
Jeff

Hi, Don and Jeff. I made a list a while back that was primarily focused on the part numbers for all the retail (universal) installer CDs. I do have some model-specific discs' part numbers, but not the one for the disc you need, Jeff. Calling Apple may be the best idea. If they're out of that disc and have no record of what its number is (very unlikely, I suspect), try reposting in the PowerMac G4 forums and seeing whether someone who has the same model can supply the number for the disc. Good luck!

Alternative power supply?

I am sad to announce the death of the 360w Power supply in my dual 1Ghz Power mac MDD, they are difficult to find and expensive and I wonder if anyone has successfully found an alternative? I have found that a standard 400w ATX PSU can supply all the voltages needed except the +25vsb. Does anyone know what that particular supply does (it is the white wire).
Thanks again everyone!

I was browsing through earlier posts and found the information I needed, If you are looking for the info your self I found it on http://atxg4.com/
Thanks!

Registering a 65w power supply? Where? How?

Just had not one but TWO G4 17'" powerbook power supplies go dead on me within the span of two weeks. The first one shorted out totally and left charred plastic and burn marks right where the cord the plugs into the computer meets the power brick. However the second literally caught fire in front of my eyes!
I was working on my laptop when suddenly everything shut down. I was confused at first but then I noticed the burning electric smell. When I glanced down at the power supply I saw blue sparks and tiny flames coming from where the cord meets the brick (computer side). I immediately unplugged my laptop first and then killed the power surge strip. The cord was totally burnt to a crisp. Gnarly...and good thing I was home when it happened!!!
Anyway, took it down to the Apple store where I got surprised looks from the staff but long story short my applecare was expired and they didn't have any 65w power supplies to "swap out" with me since all the new books use the 85w standard. Needing my computer desperately, I swallowed my bitterness and plunked down the $90 to get a new power supply. (Personally I find that price outrageous...especially since I recently had a problem with a LaCie drive and they sent me a new power supply free of charge without any hassle whatsoever!)
So I am using the one cord to power the two machines currently and I tried to register the darn thing in case this one decides to ignite but on the registration page I can't find any product listing for the power supply...or other apple peripherals for that matter. Its funny too because the Apple store staff made a huge deal of telling me to register the plug and I can't find a way to do it. I own many Apple products and they are all registered but it seems I am lost when registering something simple like a plug.
Can anyone out there help me or provide a link?
*I tried the normal registration link and there is no category for this product.
thanks!

yeah, I figured I would simply call AppleCare or take it back to the store and have them explain how to register online...since they said I could specifically register the power supply online.
also just to clarify things, the cords were not damaged but they were 3 years old. the litlle plastic flange nubs that are near where the cord from the laptop enters the brick were still intact. in fact, that is what MELTED and got all crispy and black. it seemed to me the problem was that the plug was somehow damaged INSIDE the plastic sleeve right where it entered the power brick.
I agree to never wrap the cord around the brick though. One thing that I must say to people who bought the G4 17" books when they first came out and are still using the same power supply, please take note of how hot the brick gets. Right before all this grief happened I started to notice that the brick was getting VERY warm (dare I say hot?) to the touch. I never once noticed any physical damage to the wires or connector...as far as I was concerned the power supplies were slightly less white but there were no visible signs that they were going to ignite.
At this point it is too dificult to determine the factors that may have caused both power supplies to catch fire, so I won't speculate. However, my new power supply is plugged into the same outlet as the other two and working fine. It is also much much much much much much cooler to the touch than my old power supplies.
My advice: if your G4 powerbook power supply is too hot for you to hold it in your hand it may be time to take advantage of AppleCare and trade it in for a new one OR go to your nearest Apple Store and plunk down $90. Your choice!

DC5750 New Power Supply Problems

I have a DC5750 (mini case). Everything is working fine with it. It comes with a 300W power supply. I am in the process of purchasing a new video card for it but the video card requires at least a 500W power supply. I purchased a Cooler Master Extreme Power Plus 550W PSU (http://www.coolermaster.com/products/product.php?act=detail&id=5888).
When I plug in the new power supply and turn on the PC the fans start to spin and then stop and the front power LED goes red and i get 9 continuous beeps followed by a couple of seconds of silence and then the pattern repeats itself. I have checked the HP website documentation for the DC5750 and it says that when you get these beeps to make sure that the correct voltage is set on the back of the PSU. I have made sure of this, it is set to 115V. There was also a long paragraph about the kind of power cord that you should use and I did use the one that came with the PSU and also the one that I was using before hand, but no still dice.
I have unplugged everything except the power to the motherboard when testing it and still nothing. I have sure that the 4-pin connector that goes from the PSU to the mobbo is labeled P3 to match the label on the motherboard. I tried putting in the old power supply and everything works like a charm again.
I read somewhere on these forums last night something about the CPU fan sensor and how some people had to trick their systems into thinking the power supply was putting out the same voltage as the original one. They did this by connecting two pins together but there was something about the fact that the pain had to be rated at 100ohms or something. I couldn't quite understand the solution and since it wasn't my same PC model and it was an old post I decided not to try anything of that sort just yet.
Like i said, the PC was running fine before and it is still running ok right now with the old power supply, I would like to upgrade the PSU though with the new 550W one. After i put the old PSU in i went back into the BIOS to see if there was anything related to the power supply that would stop it from booting but I didnt see anything relevant.
Does anyone have any ideas?
Thanks,
BD
Edit: I just tested the new PSU on a different system and it works just fine.

Do you remember that post about creatind a resistor connector to bypass? I have a fan not detected eror with my new PSU on the DC5750.

No power. Power supply connected and green live shows current. photosmart c310.

This barely used piece of crap lost all its power shortly after warranty expired. This is evidently a common problem as there are all kinds of mention of it on the web. It was evident before I bought this thing. Only solution by HP is to buy power supply for $16.50 and spend $11 to have it shipped. I don't even know if this will correct problem. Would like to hear from someone who has solved this problem.

OK, if you plug the printer in and it does not power up with no lights, it could be the power supply. If you change the power supply and you have the same problem, the printer is defective and you need to have it serviced.

Power supply clicks twice when plugged in.

I'm new to Mac however I've been a certified PC tech for many years. I recently purchased my first Mac. It worked fine but needed to have the fans cleaned out. I removed the components and power supply just as I would have done for any PC (I was using heel straps and working on an ESD safe workbench). Upon cleaning the components I reassembled the tower (no left over pieces) and heard two clicks coming from the power supply when I plugged it in and when I unplugged it. After troubleshooting the components individually, and still hearing the two clicks I decided to remove the power supply and test it independently. When I plug in the power supply w/o being attached to the tower I still get the same two clicks (making a relay opening and closing sound) no fans or LEDs come on. Falling back on my years in the industry and common since I decided that the power supply needed to be replaced. After receiving the new (not refurbished) power supply and installing it I'm still getting the same two clicks. At this point due to frustration I break down and call the pros. I called four Mac repair facilities (three third parties and The Mac Store) with a question "is it normal for a G5 power supply that is not connected to the logic board to make a relay open and closing clicking sound" and didn't get much help. Since I'm new to Mac I'm unfamiliar with the characteristics of the hardware. I know that if I were to plug in a normal PC power supply w/o the logic board nothing would happen, but I was told by two of the Mac techs that a Mac power supply would still make the same relay noise w/o being attached to the logic board. The problem is that I have now dropped a fair amount of money in this G5 and I have nothing to show for my investment and I don't know where to go from here. If two of the Mac techs were right then I need to send the new power supply back for an exchange, or if the other two Mac techs were right I need to replace the logic board.
The specs are:
1.8GHz Duel Processors
160G Hard Drive
600W Power Supply
2G RAM
512 Video Card
Any help would greatly be appreciated.
Thank you,
Brian M

Dear Brian,
I'm sure that clicking relais sound is the normal behaviour of every G5 power supply.
Did you use the official service manual for the specified computer? If not, you can download it here (I don't know which of the two files is appropriate for your computer, but one of those certainly is).
The 512 MB video card is not the standard configuration: the maximum amount of VRAM for an Apple supplied ATI or NVidia was up to 256 MB.
Lots of success resolving the problem and regards,
Robbert
