Source for PM G5 2.0 Dual (Late 2005) Power Supply

Ok, thanks to Steve & Roberto I now know exactly how to install a replacement Power Supply for my PM G5.
Now, as Apple will not sell me the part as it is not a user replaceable part, does anyone have any recommendations as to where I might be able to find a Power Supply ? I've searched the web but haven't been able to locate a new one nor am I certain that any of the sources I've managed to find are reputable.
Thanks
Tim

Take Apart Guide for PM G5 2.0 Dual (Late 2005)

Hello
It has been determined that my PM G5 has a blown power supply. Unfortunately I do not qualify for the repair program as I purchased my PM G5 in late December '05. So, now I'm going to have to try & replace the power supply myself.
I've been searching the web now for about 2 days & did manage to find some guides, the best of which is from '03, but I can't seem to find clear consice instructions for my particular G5. I'm stuck at the point where I need to remove the large plate (the on with G5 printed on it) that covers the CPU's. After that everything I've read/seen seems pretty straight forward.
So, anyone know where I can get a take apart guide for the Power Mac G5 Dual (Late 2005).
Thanks
Tim

Steve, looks like you have exactly what I need. Is there any chance you could send me the information, or a link to where I could obtain it? I have two G5's that need repair and I am under a deadline. Thanks in advance. (Hope someone is still watching this thread!)

I have a Late 2005 (Power PC) G5 running 10.5.7 that I purchased used from

Hi all,
I have a Late 2005 (Power PC) G5 running 10.5.7 (13 GB ram) that I purchased used from a company online that refurbishes and resells off-lease machines. It worked great until a few days ago when I came back to it frozen. It had a pixelated pattern over everything, and would not force quit, so I held the power button in to shut it down. Ever since, I still get the pixelated display, and it will not get past the startup screen. The progress indicator (under the apple) twirls for a bit, and then stops. Then nothing happens. Fans are quiet, I tried pulling out sticks of ram & swapping, hit the reset on the board, removed & replaced the battery & reset the pram. I can get the drive to come up remotely in target mode, repaired permissions and ran disk utility - says the disk is OK. Video card? Logic board? Something totally obvious that I am missing? I bought used because I am on a limited budget, and now, 6 months after my purchase, I have an expensive paperweight and had to go back to my trusty but slow dual 1ghz G4. This is really killing me personally, and productivity wise. Any insight or suggestions would be greatly appreciated!! Please let me know if there is any info I have not provided. Thanks in advance!!!

Can you boot the machine from the Leopard installer DVD without issue? If so then perhaps the OS just needs to be reinstalled. This is something you can do without erasing the drive:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
If you have the Apple Hardware Test disc for the computer, then you can boot from it and run the hardware diagnostics.

I I have a late 2005 power PC G5 that I want to bring back to life. I need to replace the original hard drive, a Maxtor 250 GB Sata. Can I replace it with modern drives, SATA 5-6 etc?

I knew I should never get rid of my old G5's. By the way, there is a browser still supported for the PPC, TenFourFox, if you're not using it already. Go to the Floodgap website (they author it) download it for free. The only thing it doesn't support is the Flash plugin, but the browser works great. Other video types are supported. It's based on Firefox, and runs most of the plugins and add-ons. It's very fast, and beats all other browsers on the browser compatibility and speed test. That's now my default on my G5's. Firefox and Safari are no longer supported. As far as the OS, both Tiger and Leopard were solid for me. The reason, as I stated before, was iMovie. The version in Tiger with iLife was far superior to what Apple changed it to. They 'dumbed it down' for the masses. Even the newest iLife 11 on my Mac Pro quad isn't is good, in my opinion. So Leopard should be fine for you. It's a much larger browser in terms of sheer megabytes and disk space, but it's fine. As far as getting an OS disc, I'm seeing Tiger for about $45.00, Leopard for $50 - 60.00 on that famous auction site. As far as RAM, I have 8GB in my G5 2.3, but you should check Activity Monitor when you are running your apps. See how much green slice you have left (unused RAM). You might find you don't need eight. A Mac Pro will grab more free RAM than a PPC machine will. I have a hard time maxing out use of my 8 on the PPC. Not true with the eight on my Mac Pro. The OS doesn't hesitate to grab and use it. You might be OK with 6GB on your PPC. More will not make you faster, as long as you still have free RAM available. As far as backup on your resurrected machine: look for a firewire enabled backup if can. Use CCC (Carbon Copy Cloner) and make a clone backup. Next time your PPC machine wipes out the hard drive, just take your Firewire drive and plug it into another PPC machine, and you can select it as your boot drive. You'll be back and running in five minutes. You can also take the physical drive out of your enclosure, and put it in your tower to replace the failed drive, and you'll be back to where you were in less than ten minutes, OS and all. The PowerMac has an 800 port, so you can do the 800 on the machine to an 800 port on your backup. A firewire 800 to 800 cable is only about $8.00. It runs nice and fast through the 800 port. I like the OWC Mercury Extreme enclosures. They use USB, Firewire 800, and eSATA, so all your options are open.

G5 Dual 2.5 Power Supply Replacement?

Hi, I tried searching for this, but there seems to be no information available for my particular model. Last week, I had the dreaded power supply failure for an out of warranty, June 2004 G5 Dual 2.5 Ghz. I brought in to a repair shop, and they ordered a new power supply for it. But I was told today that the they can't seem to locate any detailed documentation on this particular computer. My own searches have turned up the same (although plenty of documentation on other, different G5's).
As it stands, no one can seem to figure out how to access the power supply, which seems to be placed between the "floor" of the interior, and the actual bottom of the case. Does anyone know where to find the right instructions/documentation, or know themselves how to pull this sucker apart? I'd be eternally grateful for any help.

Hi. Reference material and anything detailed on the G5 is a bit scarce. The G5 Service Source is here.
The manual does not show liquid cooling. Some more info here - but again, not liquid-cooled
http://www.sharpeningbeneath.com/g5guide/
Some photos here
http://homepage.mac.com/thunderaudio/PhotoAlbum1.html
As you can see it's quite an undertaking - the risk of damaging something much more expensive than the PSU is high. Which is why, I guess, people let the shop have the problem of fixing anything they break...

Up for the Challenge? A Real Mystery (Fried Power Supply?)

I didn't know if this is the appropriate place to post this, but here goes.
I have a file server at home that runs Arch/KDE. It used to be a desktop/gaming machine, but I don't really play games on my computer anymore so I re-purposed it as a file server (SSH, Unison). It has a Geforce 9800GT video card and a 610watt continuous power supply. (No onboard video, requires a video card to function).
Yesterday I helped a client with his PC. I was trying to figure out if his issue was his video card or his motherboard, so I shut down the server, unplugged it, and removed the video card and put it in his PC to test (since my video card is known-good). After testing, I put it back in my server, connected the power cable to the video card, secured it with a screw, and continued working on my server.
About a half hour later, I noticed a really foul stench coming from my PC. I checked all the temps (CPU, video card, etc) and all were in range. I even tried a video card from a different PC and it still stunk. I traced the smell to my power supply, which stunk really bad. (Smells like a burned up motor). The Fan in the power supply turns just fine but it stinks! I unplugged it and stopped using it.
The server works absolutely fine (runs good, boots up fine, graphics works great, everything works) but it smells so bad you can smell it quite some distance from the tower so I'm not comfortable leaving it on.
Here's the mystery:
Is it possible that it's all just a coincidence, that the power supply decided to die coincidentally after testing the video card in another PC, or could testing the video card in a different PC have caused the power supply to burn up? The problem is definitely the power supply, but what I'm wrestling with is the fact that the server has been on for probably several weeks straight with no issue, and it decides to quit immediately after testing the video card in another PC. I know the coincidence is possible but it seems like a stretch.

It is probably rather simple.. I've had the same general thing happen many times. When you turn on your machine the hardware demands a lot more power compared to when it is just running. Disks and fans need to spin up and so forth. So this PSU might have been fine if you had just kept it powered on, it would never have happened. Having said that it's bad that such a powerful unit dies, but I've come to accept that most power supplies are garbage when it comes to reliability.. Doesn't matter if you spend extra $$$ on a "good" brand or if you stick to cheaper ones - they just suck in general..
If I had the money I'd buy a UPS to remove power surges and such, but until then I will have to buy a new PSU every second year I guess.
That makes sense. I emailed the company to get an RMA yesterday, and have not heard back yet. I don't have the money to buy a new one so it really depends on them replacing it under the warranty. I'm sure I'll be without the server up to a month until it's fixed.

G5 Dual 2.0 Power Supply Issue.

I am the original owner of a Power mac G5 dual 2.0 I purchased this machine in april of 2004 and it has been working nearly non stop ever since. Recently I put it into sleep mode and when I came back it had powered down and would not start up. I assume it's the power supply and I would like to know if there is anyway to tell what type of power supply and model thereof without tearing down the machine. Can anyone be of assistance.
Thanks
AJ

Hi, and a Warm Welcome to Apple Discussions and the Power Mac G5 Forum!
Well - the Power Supply Units for the Original DP2 G5s are available here
http://www.mac-pro.com/Replacement-Power-Supply-for-PowerMac-G5-600-W?sc=2&categ ory=408
and here
http://www.welovemacs.com/6612904.html
Replacing the PSU is covered at page 54 here
http://akserver.dyndns.org/macosx/hw/asm/PowerMac/PowerMac-G3-G4-G5/PowerMac-G5/ powermac_g5.pdf
If you disconnect the mains power from G5, is there a 'relay click' from the PSU when you plug the mains lead/power cord back in?
Any other sounds, LED activity, nothing?
You could try disconnecting everything except the display and wired keyboard and mouse, and resetting the PMU by pressing(once, firmly) the button shown in the photo at the bottom of the page here
http://docs.info.apple.com/article.html?artnum=300341
Earth/ground yourself by keeping one hand on the G5 casing as you press it; you do not have to remove the Intake fan bracket to get at the button.
Good Luck.

Using LabVIEW for temperature control with AMREL SPS200-50-A022 power supply

Hi, I hope someone can help me out. I'm an ME undergrad with pretty much no knowledge of LabVIEW. I am working a project which requires a temperature controller. Previously, we were using an SPS120-10 power supply from AMREL and a grad student wrote a LabVIEW VI which performed feedback temperature control. The VI would acquire temperature from a Benchlink which acquire the temperature from a thermocouple. The VI also monitor the output voltage & current and determine the power output and heater resistance from those values. When a desired temperature is set, the VI compares the actual temperature to the set temperature and adjust the voltage/current setting to achieve the desired temperature. The VI was designed to keep temperature deviation to within +/-0.5 deg C. I'm not sure of the data refresh rate, but it's on the order of seconds since the system has a small thermal mass and we're operating in the 800+ deg C range. When we were using the SPS120-10, the device used GPIB for communication with the PC. Due to higher power output demand for the heater, we switched to an SPS200-50, which only has an RS-232 port. First of all, I was wondering if someone could help me modify the VI so that it could communicate with the SPS200-50 through the serial port? In addition, the drivers for the SPS120-10 and SPS200-50 might be different. If modifying the VI to communicate through the serial port isn't enough, I would need to figure out where to modify the VI with the SPS200-50 drivers, which is provided by AMREL. If anyone would like, I can send you the VI files so that you can take a look at the block diagram and tell me where to modify it. I'm still not 100% certain I understand how to read LabVIEW block diagrams.
Please let me know if you need any additional information. Any help would be appreciated. Thanks in advance!

I have looked over your vi. First of all you have to do some changes in the "ARSPS Initialize.vi" See picture.
The best way to check instrument communication is to send the *IDN? Command. The instrument will indentify itself in response to this command. The vi I have included is a labview example. Use this Vi to test your communication. Do not progress before this is working. The VI is also an excellent example on how to set up and close down RS232 communication.
The VI "Tfeedbackpowercontroller-nolvdt-Dinh.vi" looks OK so I guess it will work then your RS232 communication with the SPS200-50-A022 is working
good luck
PS as mentioned before you will find all the RS232 details in the instrument manual
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Which video card to get for my late 2005 Dual 2.0 G5

Sorry if this has been answered in others posts. I have been a bit confused on what card I should be getting for my G5.
I have a late 2005 model (last generation of the PPC) and it came with a 6600LE PCIe 128mb card.
I would like to get a better video card (256 or 512) but I don't want to break the bank. I read about the ATI x1900 but I wasn't sure what the differences were between the two versions. There seems to be an x1900 MAC edition and an x1900 XT. Can someone let me know which card I need and whether or not there are other choices that might be cheaper.
Thanks.

I recently purchased an ATI Radeon 9600 Pro PC & Mac edition and installed it in a PowerMac G5 2.0 DP to power a 30" Apple Display ... installed easily and worked perfectly. It was $186.98 at Amazon, but is currently unavailable there; $204.99 at Small Dog. Here is the detailed description:

Sound Card for Power Mac G5 (Late 2005)

Hi folks, I'm sure this question has probably been asked here before but I'll appreciate it if someone could give me some info on pci-e sound cards for the late 2005 Power Mac G5.

Hi Joe Goes;
Instead of going to PCIe cards which I think would be extreme expensive, I would suggest connecting the optical cables to a receiver or amp and then connecting the multiple set of speakers to it. Which is what I did. I picked up an amp at used equipment table at the local sound store for nearly nothing. In fact the optical cables I needed cost me more the amp if you can believe that.

G5 Powermac Dual Core Power Supply Issue

My G5 Dual Core 2.3 GHz was working fine till this morning when at about 6:00 AM the power supply started making a bunch of noise. Luckily I was at home not at work so I pulled the plug...waited a while, powered on again, saw the apple logo and decided to turn it off till I get it fixed.
This is the third G5 I have with power supply issues. The first one was a dual processor that hums when doing a lot of networking or when attaching USB flash drives...so apparently there was a extension program on that one. I sold that and switched to the dual core machine, then both of the dual cores had power supply issues. One got replaced under Apple Care. The 3rd one just had the issue happen.
Anybody having bad luck with these? My old G4 DP 1.42 has been running almost flawlessly since it came out (only replaced the main fan for a more powerful and quieter unit).
Have the power supplies for the Dual Core G5 machines been redesigned or should I expect my new one to fail again?

Hi Jack,
I'm sorry. You did note that with your first G5 you knew of the extension program. Too early in the day for me I guess. Personally I haven't sensed from the G5 discussions that Power Supplies have been a major continuing issue, but there certainly have been a lot reported. Usually it's Logic Boards that keep getting fried for one reason or another. Fortunately it doesn't seem to be the most expensive thing to replace, especially if you buy a used one. Maybe someone will chime in who is more observant then I am this morning.
For what it's worth I still have the first Mac I ever bought which is a PM8500. It still runs fine whenever I pull it out from it's dusty storage. By contrast this is my third G5.
Edit: Up early and fasting for a test... I just caught your reference to 3 years. That time frame I have seen a lot here, usually 3 years plus a few months, just out of Applecare. Apparently for G5s thats like 90 in Mac years.

Sample programmes in C# for setting voltage in a TDK lambda power supply

please provide some guidance for setting the voltage of a TDK lambda power supply through GPIB. Any driver software needto be installed?

If you use an NI GPIB controller, then you will need to install NI-488 and it is recommended to install and use NI-VISA. There will be coding examples installed with the drivers. You don't mention the model number but you might find an existing instrument driver from NI or the vendor.

What kind of wireless card I need for my Power Mac G5 (late 2005) Dual 2 GH

hi there,
I have for sometime now a "Power Mac G5 (late 2005) Dual 2 GHz PowerPC G5", and recently I have been thinking to get an Airport extreme wireless card with a bluetooth on it, which could work on my machine.
I have already try to deal with apple representatives and Apple sales people to give me a hand on the matter and so far is been a nightmare to approach this guys, tired of wasting time and effort, so that is way I am posting a topic on this section to see if you guys could give a hand on the matter.
All what I would like to know is what kind of wireless card I need for my Power Mac G5 (late 2005) Dual 2 GHz PowerPC G5 (version 10.4.11) and where I could buy one on line to install myself.
This is the mac unit I have.

You're welcome. Funny how Apple works isn't it? If it's any consolation, that Airport/Bluetooth card doesn't show up on the Apple U.S. store either. I don't think they ever intended it to be a user installable part, so perhaps that's why they don't offer it for sale. Do you have any Apple Authorized Service providers in your area? I'd think they'd be able to order the card as a replacement part.
Can you give a little more detail or a link to the gadget you're referring to? It sounds like a USB dongle to enable Wi-Fi, but that must be a third party solution, since I don't believe Apple ever offered something like that.

You need an Airport Bluetooth module with the required runway card.
Here is the kit:

You can use a faster memory, but it will not run faster, will likely report wrong and may give other issues.

What happened to dual sources for input and monitoring?

In LP7 you could set up for two different hardware sources for input and monitoring. That's Gone?
Gee's there is so much wrong with LP8 and all the constant crashes, makes it an unusable program. Apple really needs to get this fixed. They should already had a fixe. Lord knows they have seen enough disgust from users. To go this long without any updates is shameful! IMHO!
