PowerPC :: Use Case For New Hackintosh - Replace Power Supply?

Apr 14, 2008

After reading about Psystar and all that crap I have become inspired. I want to build my own hackintosh . I have an old G4 Gigabit Ethernet PowerMac that I aquired a few weeks back. I was wondering if it would be possible to gut it and use the case for my new hackintosh. Will a standard mobo fit in it? Can I easily replace the powersupply?

PowerPC :: Video - Replace Power Supply Burned Out?

Feb 21, 2006

I have a first gen imac g5 (bought it in dec. 2004). So far I've had three major problems with it:

1. After 6 months of use, the power supply burned out and had to be replaced.
2. 3 months later the well known video problems due to faulty capacitors appeared. The midplane board was replaced.
3. I was out of the country for 6 months; after the midplane board was replaced in August my imac was sitting unused. Booted it up yesterday and the computer would just hang. Took it to the genius bar at the apple store today and was told the logic board has to be replaced. Luckily, though the computer is out of warranty, Apple has extended the warranty for this specific problem.

At this point, I am very frustrated. I am going to call Apple and request that they replace my imac with a new one. It is obvious reading the posts here and Apple's boards (btw, before Apple's board monitors started censoring and delting posts that address these problems - my post on the Apple board yesterday was deleted by the monitors) that many users have had lemons with the first gen imac g5. I consider three major problems in less than a year to be symptomatic of a "lemon". If Apple doesn't replace lemon imac g5's what are the alternatives...I wonder if they would buckle if enough people threaten a class action lawsuit. Something must be done to alert the general public about this problem.

PowerPC :: Mounting The Power-supply From The 2004 On The 2005 Is The Power-supply Compatible Or Not

Dec 29, 2010

I have a PowerMac G5 with the first motherboard that is out of order, and another PowerMac

G5 Late 2005

with 2x2.0GHZ

Mounting the powersupply from the 2004 on the 2005 is the powersuply compatible or not?

EDIT: I looked on Mactracker and compared the two:
Max Watts in the first is 604W and 450W on the late 2005.
I want to put a powersuply from a G5 2004 (604W ) on a G5 2005 that had a 450W powersuply is this possible ?

PowerPC :: Beige G3 Power Supply Jumpers

Aug 2, 2006

I am trying to switch out mobos. I want to put a desktop mobo in a minitower case. But my understanding there is a jumper that can be changed to switch between the models. Has something to do with the power supply differences if I remember correctly. Anyone know where on the motherboard that would be located? in need to find it because currently using the desktop mobo in the minitower case it will not power on at all.

PowerPC :: The Power Supply Recently Blew On It?

May 14, 2009

So, I have the latest 2.5 G5 quad.

The power supply recently blew on it so I had the local Apple shop replace it. I brought her back home and powered her up for the first time and the fans are on full blast the whole time.

Usually the fans would be on high during start up and while shutting down...but they would ALWAYS slow down when OS X is loaded. Now they are on high all the time.

specs: 2.5 quad, 6.5 gb RAM, 2x 500gb HDD's, GeForce 7800GT, 10.5.6 (I know 10.5.7 is out...I'm installing it tonight, as it took over an hour to install on my iMac's)

I know I can just take it back to the tech, but if I can fix it with a simple setting then I'd like to try that first.

PowerPC :: G4 Tower Power Supply Dead?

May 19, 2010

Have a Power Mac G4 MDD - Apple genius bar looked at it and told me probably need a new power supply (shutting down at will and having trouble powering up but before that the computer was running well) and I'm not sure if I should get a used or new one on ebay or if you have a better idea. Can't afford a whole new system so want to resurrect this one.

PowerPC :: Quicksilver Power Supply On A Gigabit Motherboard?

Mar 7, 2008

Recently I didn't do my research, and I purchased a Quicksilver power supply to put on a Gigabit machine. I noticed it had four extra pins which look like some of the ones they use to power processors in some PCs (tho I've come to find this is for the ADC port). I dug a little deeper (Googled "powermac_g4.pdf") and found out that some of the pins have differences between the Gigabit PS and the Quicksilver PS.

Has anyone else had an experience like this? Will the PS work without any wirecutting or do I need to get a new one?

PowerPC :: Bad Power Supply, MDD G4 Trips APC Overload Circuit?

Aug 30, 2009

I recently fired up a old MDD G4 at work, and after 5 seconds or so, the APC unit that it was connected to started warning that there was a current overload, and killed the power port. I plugged in another computer to make sure that it wasn't a general overload, and it ran fine, so it's a problem with the MDD. The power supply area smelled a little different, and it was hot. The system powers on completely (fans, hard drive, etc.), but it just trips the overload circuit by drawing too much power. Is there a way to take apart the PSU and see what's going on?

PowerPC :: No Airport Card Installed After Power Supply Replacement

Nov 11, 2008

I just picked up my iMac g5 20" (2.0 GHz PPC) from the Apple Store for having the power supply replaced. Now I've lost all traces of the built-in Airport Extreme Card: When I click on the now hollow diamond-shaped Airport icon, I get a grayed-out prompt stating "No Airport card installed". Any record of an Airport Card under System Profile comes up with "No information found". My Airport Express does not show up in Network settings either.

Airport Express works fine in my Macbook Pro, so I know it's not something wrong with my Airport Express. I tried installing the "Login & Keychain Update", but can't: "You cannot install Login & Keychain Update on this volume. This volume does not meet the requirements for this update". Ran Disk Utility and came up with errors and unable to repair disk. The iMac was fine going in - except, of course, for the random shut-downs from a failing power supply.

PowerPC :: Replacing Power Supply Board On IBook 12" G4

Dec 16, 2008

I've been lurking for the last 12 months but haven't posted until now. Does anyone know if it's possible to purchase a new PCB and lead for the power input. My youngest kid pulled my mac off the sofa and it landed right on the input which knackered up the lead forcing me to buy a cheap chinese job. I've taken the cover off and pulled out the small PCB to inspect it and it did have a cracked solder. I fixed that but the connection is still very fussy, I can't move the mac much or it will switch off (dead battery too). While I'd love to go out and buy a brand new macbook I simply can't afford it right now so patching up this one is my only choice. It needs ram, new battery, proper lead and power supply PCB. All easy to find except the PCB.

PowerPC :: G4 MDD Power Supply Repair / Small Thin Atx Replacement?

Sep 26, 2009

I have a MDD quicksilver with a bad power supply. I have done some research and have found that the MDD psu does fail more than most. One of the biggest problem is cost. As most of you know replacements run $125 and up What I would like to know is has any one found out what actually goes wrong in these psu's? With the amount that have failed I would guess it is a few components that are commonly going bad on each unit. If I cant figure out whats wrong with the unit, maybe a replacement? I have seen the standard atx power supply mod for the mdd but I was thinking something along the lines of the same form factor as the factory psu. the guts could fit in the factory psu enclosure with rewired new 24pin plug. Again I am just throwing this out there maybe some one all ready did this.

Hardware :: Test A G5 Power Supply Like An ATX Power Supply?

Feb 12, 2008

My 2*1.8Mhz G5 tower (second version) shutdown two day ago and refuses to turn up again. I have absolutely no sign of life, not even the external white led or the internal red one. I'm trying to figure out whether it is the power supply of the start button which cause the problem.

Is it possible to test a G5 power supply like an ATX power supply, by connecting two pins which would make the fans start ?

Power Mac G5 :: G5 Power Supply Beeping/Churping Corrected With Leopard

Nov 8, 2007

I made this a new topic because I think it is important enough to do so. Probably most of those that originally complained about this have moved on to the new MacPro but I am sure there are still enough G5 owners out there that still have concerns about this topic.

A clean install of Leopard eliminates the infamous power supply beeping

Its amazing, my G5 is like a new machine; no more of the annoying power supply beep; although, I learned to live with it after a while and didn't even notice it. However, the silence is now very noticeable.

Mac Pro :: How Far Can You Tap The Mac Pro's Power Supply

Mar 16, 2009

It has no doubt come to the attention of many that the Radeon 4870 requires two PCIe six-pin power taps off of the motherboard, which is exactly how many  allots. Say we wanted to use a GeForce 8800GT and a 4870 at the same time, which would require a total of three PCIe six-pin power taps. What I've read on the forums here indicates that powering them would be possible, but what ways would work?

As far as I can see, I've got two options:

1) Split one of the 6-pin power taps with a Y-splitter, and use the resulting two taps for one card and the other tap for the other card.

2) Use one of the ODD 4-pin molex power taps, convert it to a 6-pin tap, run it down to the card. But I'm running two optical drives; would it be possible to split one of those power taps into two, then run one out converted to a 6-pin and into the card?

I don't know nearly enough about the motherboards and power sources to know which way would work - if any - and if there is any risk involved. I'm running an early '08 mac pro, but I'm curious if this would work in other models as well. Anybody know enough about the hardware to say?
