G5 Power Supply Zapped. Design defect?

Had my new Powermac G5 processor for 4 months and when I turned it on recently, I heard a very loud snap. Would not turn on after that. Did the internal power reset procedure found in the Apple support pages. No good. Took my processor to CompUSA for service. Power supply was blown. Apple tech at CompUSA said he has had 3 other G5 units in for the exact same problem! Wanted to post to alert others and find out if this is a problem others have run into.

I had the same thing happen to me back in October of 2004, actually. I bought the computer in July of 2004 and in October, nearly 4 months to the day, my dual 1.8 G5 died and it was the power supply. It took the San Francisco Apple store 19 days to repair it (they broke the case during the repair and had to order one from the Apple store in Chicago). The main gripe I had was how long it took them to diagnose the issue. They replaced a whole slew of other stuff first because the power supply tested ok. In the end, the summary statement of how much they spent was about $300 more than I paid for the machine. They could have just given me a new machine and made me a happier customer and come out financially better off than they did in the long run.
And yes, it's a chronic problem. There's an entire section devoted to it at Macintouch: http://www.macintouch.com/readerreports/powermacg5/topic4026.html

  • HP Pavilion s5-1224 (Windows 7 64-bit) power supply problem

    Can 550W SATA Power Supply work/ fit my hp pavilion model: s5-1224?
    link:
    http://www.ebay.com/itm/550W-SATA-Power-Supply-New​-design-with-larger-fan-Pulled-from-HP-Pavilion-/2​...
    I want to upgrade my power supply, but I am not sure if this will fit.
    Any replys will be appreciated

    I would be a little cautious when ordering from eBay.  It's a used power supply for $5 and the seller used a HDD term (SATA) to describe the power supply.  Granted, they could just be saying that it does have SATA power connectors. 
    It looks like a standard ATX power supply. 
    To answer your question, no that power supply will not fit your system.  Your particular system is a slimline and requires a unique power supply to fit the case. 
    The following is the original power supply your unit came with.  You will need one that is like it. 
    http://www.amazon.com/Genuine-Original-Supply-FH-Z​D221MGR-633195-001/dp/B00BJ0QW16
    This site claims it is a slimline power supply and provides the dimensions of the power supply.  I would get the dimensions of the power supply currently in the system.  If they match, then that would more than likely be an upgrade for your system.

  • Designing variable output power supply

    hi 
    could anyone  help me out in designing variable output power supply ?
    as i am new to this please post the circuit and also the step by step procedures in developing the circuit.

    Hi rckz,
    The link below has an example of a variable power supply.
    http://www.google.ca/imgres?imgurl=http://howcircuits.com/downloads/circuits-and-diagrams/power-supp...
    You can try to find the components in Multisim by right-clicking and going to Place Component. You can look through the database and place them on the schematic and then wire them as shown in the schematic.
    Hope this helps.

  • Re: Power Supply Problems/ Bad Design

    The moderator of this site seems to think that any external power supply can have the same problems as apple powerbook supply. "Not so", say I ! Most PC notebooks and yes, I do use them, have a fairly sturdy cord on both sides of the connection. Should one find oneself in a situation without a power supply for a pc notebook it is usually possible to get one from a local Radio Shack or international electrical store. Not so with apple powerbooks. the connections are specifically apple and although there ae a few generic replacement PSU they are not generally available only from mac speciality stores. Why apple decides to design what is obviously a flimsy (my electrical gaffer on my movie looked at it and just laughed)and possibly dangerous device is beyond me. It occurs to me that with all the innovative design apple has come up with in the past has gone to the designer's heads. Now we are faced with a 'magnetic' connector on the new powerbook pro line. Are you kidding apple ? Please just give us a simple, generic power supply and conmnector so that we travellers can rest in peace knowing we can replace the PSU anywhere in the world.
    BTW my PSU was smoking and sparking when I awoke in my hotel room until it just gave up.

    Two alternative power adapter manufacturers:

    http://eshop.macsales.com/item/Newer%20Technology/APLN2M/
    The most common issues people have with Apple's adapters that I've seen are (not that this applies to you, but perhaps one will refer to something you've done that you didn't realize could cause harm):
    1. They pull by the cord and not the bulb.
    2. They push in without looking.
    3. They let the cord bend at the bulb or at the brick. Give it at least two inches of slack.
    4. They don't remove the plastic wrapping that is clear from the brick when they first get it. This under the wrong conditions could create an overheating condition.
    5. They rely on unreliable power sources. Some older houses have issues with giving reliable power to outlets. Using a backup battery surge protector like those from APC can help.
    By the way, my father's Dell power adapter had to be replaced too. Non-Apple notebook power adapters are actually more flimsy than you give them credit for. Part of the problem is designing the transformer to be in such a compressed space that is lightweight too. Until people don't mind the extra weight of a full fledged desktop power supply inside a notebook, thus allowing standard power cables, or a room temperature superconductor is invented, this will be a persistent issue. Take good care of your cords, and don't let them bend so much that they fray.
    I might add, I went to Radio Shack, and they had the parts for me to build a power adapter for my Powerbook. Unfortunately the transformer brick would have been 3 times as large and as heavy.

  • My 27" Imac (A1312/EMC2390) keeps shutting down unexpectedly with no warning or "screen of death". I replaced the power supply, reset the SMC, and zapped the PRAM, but the problem continues. Can anyone help me?

    My 27" Imac (A1312/EMC2390) keeps shutting down unexpectedly with no warning or "screen of death". So far I reset the SMC, and zapped the PRAM. I even replaced the power supply but the problem continues. My error and system logs seem unhelpful too. Can anyone help me out?

    You can get a shutdown like that if the computer gets too hot. Make sure the air intakes on the bottom and the exhaust vent on the top are clean and are not blocked by something in your workspace like papers or the back of the computer being too close to part of the furniture. You need a good six inches (15cm) of clearance between the exhaust slot and other objects or surfaces.
    Anti-virus/internet security software, especially the "pay for" kinds, can increase operating temps. So can third-party backup software furnished with many "name-brand" external hard drives.
    Fan motors and/or temperature sensors can fail. If you have the original grey disks that shipped with your iMac, find the on that has Apple Hardware Test (AHT) and run it. If you have a failed heat sensor or fan motor, it will detect it with an error code containing "SNS" if it's a bad sensor or "MOT" if its a bad fan motor.
    AHT instructions here:

  • 6-month old Mac Pro has already had a new logic board and power supply

    At a cost of $400 in shipping and a one-month wait, my 5-month old Mac Pro got a new power supply and logic board
    Now I keep getting kernel panics, runaway kernel_task in Activity Monitor, and corrupted boot drives
    External Firewire drives work some of the time, and occasionally my USB devices dont work either
    This computer is a nightmare - how do I begin to figure out if this is OS (10.6.4) or hardware related?
    The extended AHT test reports that all is OK - as does an extended memory test using Applejack
    Should I do firmware updates and re-install the 10.6.4 combo pack, or am I just wasting more of my time?
    I've got 4 macs and this is the only one that works badly - I think Apple's OS updates are getting as bad as Windows updates

    My first question is why you spent $400 to get a 5 month old system fixed. That should have been covered under the warranty. So someone ripped you off, or you left out some key details.
    And if you had both the logic board and PSU replaced, did you ever stop to think that maybe the problem lies with the power coming into your house? It's not really the big power spikes or blackouts you need to worry about, since those are pretty rare. What you need to worry about are the small fluctuations in voltage that happen several hundred times a day, if not an hour. Sometimes there's not quite enough power, other times there's a little too much, and all of this takes a steady toll on the PSU. It will do what it can to try and feed the rest of the computer a steady diet of electricity, but sometimes a jolt will get past it and start damaging other components. It could even cause data corruption on your HDD.
    If the PSU and logic board already went, who knows what damage it may have caused to anything else. It may just be taking longer to show up.
    It might also be that whomever ripped you off to the tune of $400 simply traded you one defective logic board for another. Or maybe they don't really know how to protect against ESD. I once saw a repair shop where the techs smoked in the same room they did the repairs. Sadly, for every one good tech out there, there's probably at least 3 complete idiots. Kind of like auto mechanics.
    And I never have problems with Windows or Apple updates. Seems like on Windows the majority of people who have problems with updates are either running some program designed to change the way Windows looks or messes with low level system files, or they have a malware infestation they were unaware of/oblivious to. Most of the people who have problems with Apple updates seem to be the same way. They're running some truly bizarre programs that mess with the system in ways programs were not intended to mess with the system. There's generally a reason OS vendors provide an API for developers. You deviate from that at your own peril.

  • IMac G5 Power Supply Going Bad Again?

    I had my power supply replaced back in December 2005. Now my 20" iMac ALS is shutting off randomly again. Often when starting up it the fans will get loud and the computer will shut down. When booting from a CD, the computer will do the same thing - most of the time. I got it to boot up so I could run the Apple Hardware Test, but it shutoff during the mass storage segment. (It said my Logic Board was okay). I was able to boot once using the TechTool Deluxe that I got with my Protection Plan and I had no errors. I've tried several times to boot up with the DiskWarrior CD, but the computer always shuts down before it even gets past the grey Apple.
    So, I can sometimes boot from CD. The computer sometimes shuts off suddenly. The computer sometimes won't boot beyond the Apple until shutting it down and trying several times. However, sometimes the computer starts right up.
    I've ruled out software, the hard drive and probably the Logic Board (since it passed the Apple Hardware Test). Can it be anything beside the power supply?
    My iMac falls under both extended warranties and I have AppleCare Protection Plan until sometime in 2008. If only it wasn't so hard to get a reservation at the Genius Bar...

    Hey... had the SAME thing just happen to me. It IS the power supply, trust me. The model iMac you have had defective power supplies from the start. It was/is just a matter of time before they go out. The GOOD news is you have Apple Care (although you are probably covered under the Repair Extension program for this issue/iMac model)... Now beecasue you HAVE Apple Care and are not gonna get this fixed under the extension program APLE WILL COME TO YOU to fix your iMac. It is part of your Applecare agreement. Tell them it is impossible for you to bring this heavy, awkward (albeit a design wonder) computer to a genius bar -- which are often situated in malls and hard to get to areas carrying an iMac. Tell them you just can't do it. They WILL come to you. It actually free up the Apple Stores from doing the repairs and tying up the genius's... I just did this, a three day turn around and I never left my house... and I live in LA where we have at least 6 Apples stores in my vicinity. Hope this helps! If it does can you reward with a "helpful/solved" (I know that's tacky to ask for but this will solve his probably)... Do it, call Apple, tell them you physically can't carry it in (probably the scenario) and they will dispatch a tech. GOOD GOOD Luck.... I know this shut off thing can make you crazy!!!! Kudos for buying AppleCare!

  • Replacing Power Supply Problems

    Apple Care had kindly sent me a new power supply. It is a self servicing part, i.e. I have to install it myself. Tried for 2 hours yesterday to get the old one out...didn't work.
    The problems:
    1. Middle screw on back of power supply does not get loose [the screw close to the power cord connector]. I tried to pull the power supply up while loosening screw...no success. Did anybody run in the same problem...how did you get this screw unstuck?
    2. Middle case screw [the one at the bottom of the computer] needs to be turned to the right...which is in contradiction to the downloadable manual...but the front ot the screw still touches the power supply...and possibly holds it in.
    How easy should the power supply come out...how much force can I apply without breaking the computer's case?
    3. Ambient light sensor connector: comes as separate cable. Since I have not gotten the old power supply out, I do not know how to connect the cable to the new one. There does not appear to be a designated hole on the power supply.
    Experiences welcome!
    Thanks

  • IMac G5 20" power supply problem

    The power supply on my 20" G5 recently fried. Somehow I had the activity monitor showing that the "FaxJobMgr" was using about 70% of my cpu. I had had that problem before and the computer was very warm. I quit that process but shortly after that there was an acrid smell that I ultimately found was coming from the power supply. When I re-started everything came up to the desktop but then it shut down just as if the plug were pulled. I see that there were many issues with the power supply on this first generation G5. I took it to the Apple Store and they say it is the power supply AND there appears to also be damage to the logic board. $734. I'm wondering if maybe its only the power supply and they are just being cautious that there might be damage to the logic board so just replace it or buy a new computer. I thought I might try to replace the power supply only, but then that seems to be about a $120 that might be gone. Any thoughts would be greatly appreciated. Thanks

    Generally speaking, the defects which affect a logic board and power supply in that family of products are similar, but there typically exists no causal link between them. It is possible to have a logic board affected by the defective electrolytic capacitor issue, a defective power supply, or both.
    You can readily determine if the logic board is defective by examining the clusters of capacitors on the logic board for bloating, distended tops or leakage. If they exhibit such symptoms, your logic board can be repaired for $ 189.00 by contacting this company.
    You may also need to replace the power supply, thought that determination is best made once the logic board as been verified as good or bad, and replaced, if you elect to do so. Power supplies for this product family generally cost roughly $ 139.00, and are user replaceable. Replacing the supply in a unit which exhibits the defective capacitor issue will not correct the logic board related problem, and may—under relatively rare circumstances—cause the eventual failure of the replacement supply.

  • UPS Causing Disturbance to Mac Pro Power Supply

    I have been doing a lot of work on upgrading two Mac Pro's over the last few days. I have one attached to an APC UPS 1300VA 780W rated. Normally this Mac Pro is under my desk, so I do not here it. During the process of one of the upgrades I had the Mac Pro sitting right in front of me on my desk. As soon as I powered it up, I could hear this disturbing "hum" or "buzz" coming from the power supply of the Mac Pro. However the Mac Pro seemed to operate fine.
    I decided to unplug the Mac Pro from the APC UPS and into a regular Tripp-Lite wall surege protector with no UPS. The noise was significantly reduced. Therefore my question to you is:
    1. Do you think the fact that the APC is creating the problem or introducing a different signal (maybe not true Sine Wave) than what is required by the Mac Pro?
    2. For those that have a newer Nehalem Mac Pro and they have access to the back, how would you rate the "hum"? Is it what you would expect? Now that I have it off the APC UPS, it seems more normal (it is audible, but only with my ear close to it).
    3. How well are the power supply units in the Mac Pro designed? Enough to handle immediate loss of power? What about cleaning the power coming in? Sometime the voltage drop across my AC outlet is 110V to 120 V.
    Mike

    RS? XS? something other than those? The linked discussion OP had an XS and went to SMART unit. Before I bought CyberPower to replace one of my two 1500VAs (one XS and other RS) I decided to ditch APC this go around. And, glad I did. Quiet, green, stand-by mode.
    The 2008 had bad inrush current, and ever since the G5 Quad with 1kw PSU people have been looking for the best UPS.
    One article talked about PSU efficiency, and apparantly Apple's didn't match the 85+.

  • HP Z400 Workstation Power Supply not Supported

    Good Day All,
    I would like to seek help on the issue that i am currently facing.
    Currently, I am using an HP Z400 Workstation and decided to switch to a bigger casing. I Bought a Full tower and casing and just realized that i am unable to move the power supply (425 Watts) as well due to the cables are too short to reach the CPU main Powers.
    So I bought a separate Power Supply (Cooler Master M2 Silent Pro 850 Watts).The cables are perfectly enough to reach the CPU main power source. After putting everything the pc won’t turn on……
    I thought my newly power supply was defective and got a replacement at the same day. I tried the new Power supply and simply does not want to turn on… this is getting frustrating as I am unable to figure out what is really causing the issue.
    I also tried to just plugging the cables at the Main power and removed all the additional devices just to test but still no luck….
    I started checking forums… there is only one post regarding about unable to change any other third party Power Supply for this HP Z400 Workstation. I guess it apply to all HP Branded as well as Dell.
    Guys I need your help as I don’t want to make a mistake again on considering to build another machine just because this one was not working… Maybe there is one there that manages to bypass or have a resolution on how I can successfully upgrade my Power supply using the same HP Motherboard.
    Here is my Current Specs..
    Processor
    Intel® Xeon® Quad-Core Processor W3565 (3.20 GHz, 8 MB cache, 1066 MHz memory)
    Chipset  Intel® X58 Express

    Will wait for your kind reply,
    Thanks

    The reason it won't turn on is because pins 21 and 23 are not in the standard ATX PSU configuration. Your motherboard works with an HP configured ground on pin 21 and +12 VDC instead of the ATX  (ATX12V v2.01)standard unused pin and +5VDC respectively. 
    Z400 PSU connector
    Standard ATX PSU connector
    I have not seen a non HP PSU available that would work without modification.  
    Not all HP's are built with propietary PSU connections most newer, non-business models use the standard ATX PSU configuration.

  • Power supply voltage upper-non-recoverable

    Hello,
    One of our customers is seeing the following errors occur intermittently across all 4 power supplies in their chassis. They are running 2.0(2q). The chassis is powered via an APC UPS and PDUs, and there are no power events or alarms from within the APC InfraStruxure tools. Has anyone else seen these errors in 2.0(2q) or is this error indicating a voltage fluctuation from the UPS?

  • 12 V power supply / built in airport

    any plans to add a 12V power supply input?
    this would be very handy for the usage in motorhomes, cars, ships etc.
    also a buildt in air port express would be great, one wire less...
    so apple, go ahead and make Hi Hfi even better

    You could introduce some noise by mounting a power supply inside of the SCXI chassis. The chassis itself does provide some degree of shielding, so you would be eliminating some of that shielding by placing that power supply inside. However, we have no specs for that because the chassis was not designed for that application. Another option may be to use the SCXI-1124 analog output module. While it has 6 channels with a +/- 10V range, you can cascade channels to get up to 60V per module. Below is the link to the SCXI-1124 produce page. I hope this information helps.

  • M7332 Power Supply-How can I tell if it works?

    I have a power book G3 Lombard, I believe. I have purchased a brand new power supply from ebay. But my computer won't start. The battery is dead too. It has been sitting idle for nearly a year.
    My question is- shouldn't I be able to test the output of the power supply with a voltmeter to prove that it works? I have purchased 3 different power supplies and they all produce no electricity at the outlet tip.

    ABoney,
    Welcome to the Discussions.
    You cannot safely measure the voltage of the plug which connects to the power port due to its design. The center post has three insulated parts with the tip being one and it does not carry power.
    Did the powerbook work the last time it was used (last year)?
    First, try resetting the power manager:

    If unsuccessful and since the 'book has been stored for a year, I would recommend this procedure:
    Remove the power adapter, main battery, and optical drive; position the display vertically since the 'book will want to tilt backwards. Lift off the keyboard (place it face down on the palm rest...do not disconnect the ribbon cable), then disconnect the PRAM battery as shown in this photo; click to enlarge the top photo.

    Without any reassembly, connect just the power adapter and try starting. If successful, press the power button until it shuts off (disconnect the power adapter if it will not shut off). Reconnect the PRAM battery and test startup again. If successful, shut down and reassemble the 'book; if it fails to start, disconnect the PRAM battery, then reassemble the 'book.
    The powerbook will run fine without the rechargeable internal backup battery a.k.a. PRAM battery and these can be replaced for about $20.
    The purpose of this procedure is two-fold: You may have a corrupted power manager that will not clear normally and/or the PRAM battery has an internal short that prevents startup.

  • Replacing power supply in G4

    This isn't totally on topic, but it's the closest I can find in the discussions.
    I run several macs on ethernet. I have an old G4 Power Mac, dual processor, 500mhz Model M5183, which I use to run a flatbed scanner. The scanner software can only use OS 9 which is why I've held on to this G4. Last weekend, it would not start up at all. I replaced the battery and reset the little button beside the battery, but when I plug it in again, still nothing.
    A kind friend gave me another G4 to use for parts. I'm thinking that perhaps the power supply is bad on my G4 and that I can swap out the power supply from the gifted G4 (it's the same model as my original). I've looked at the instructions on the Apple website (where the promised link to the instructional video doesn't work, BTW.)
    Can anyone advise me on this? I've contacted a Mac service provider, but the new power supply would cost more than the CPU is worth, plus the scanner is 10 years old, so it may not last much longer. Anything else to consider? I'll have an extra logic board, too, so if the power supply doesn't do it, perhaps that will do it.
    I'm not a techie person. I'm a freelance graphic designer, so excuse my ignorance if it's apparent.
    Thanks for your help. Sorry about the long post.

    The G4 I was given is semi-operable; I don't think it's hard drive is working. Hadn't thought about swapping hard drives. My original HD is 40Gb and the gifted G4 is a 20Gb. Would that make any difference?
    I'll try replacing the power supply and see how that goes because I think this second G4 is kind of beat up.
    Thanks for the link. I had found it myself. That's where the instructional video link is that didn't work. But the printed info looks good and I'll use that as my guide. I was fishing for more info about unexpected problems I might encounter.
    Thanks. I'm sure I'll be back in touch.
