I hav" a "late 2004" G5 2.0 dual processor. To upgrade graphics card, I find many require a power supply splitter. Do I have a molex 4-pin connector? I can't see the location inside the box.
Information:
G5 dual 2.0, 2.5Gb
Mac OS X (10.4.3)
I'm referring to this thread here:

There's 2 images that are missing so I'm a bit confused. It seems pretty basic but I have to ask just to make sure. The cables that came with my card looks exactly like the image in the post. It has 2 inputs PER cable. With the molex split, I'm guessing I plug only 1 in per cable, so does that mean the other input is left hanging with no connection? Is there a specific input on the cable that I use? I notice there's only 3 colors with yellow and black leading to different holes and the brown one leading to the same hole. It seems so basic, but so confused without the 2 missing pictures.
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 ?
a friend recently gave me a g5 power mac that had some issues, and the failure was described as intermittant. The machine supposedly would work properly when booted and start freezing up after time, but if turned on the next day it would work properly for some time. I assumed it was an overheating issue, but apperently there is more to the picture. I have tried booting the machine quite a few times and the display always reads no signal. The machine sounds as if it were booting normally, but there is not output. At first I assumed it was my display cable, which was a DVI-D single link, however the DVI-D dual link cable leads to the same result. Is it nessicary to have a DVI-I cable? None of the error LEDs light up on the motherboard. After doing some hunting I haven't found anyone with the same issue, but I am wondering if I should assume the graphics card is dead. What steps do I need to take to isolate a graphics card failure in a power mac g5?

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 ?
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.
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.

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.
Anyone know where I can buy an extra AC cable for the MagSafe 85W power supply that came with my late 08 MBP? I'd like an extra cable and I'm not interested in ponying up the dough for the entire power supply. I checked the Apple Store and Macmall, but haven't found anything as of yet.

Power supply partially expired on my 2.3GHz G5. Have found a donor. Manual says remove logic board before power supply. But you could remove power supply with board in situ on older G5s...

I'm looking on cragslist right now for an older powermac to use as a media hub and I think I found one. It appears to be an AGP G4 PowerMac (500Mhz-ish). I have a 256MB graphics card I was using with my PC, I was wondering if I could plop it in and it would work? I know it's probably a pipe dream, but it doesn't hurt to ask
View 7 Replies View RelatedI'm upgrading to a Nvidia GeForce 8800GT graphics card on my 1st gen Mac Pro. I know how to install the card and that it needs aux power to work. The card has the aux power cable, but I'm not sure where to plug it in. There is a egg crate looking connector near the fan. Is this the aux power connector? There are two little prongs on the cable? Do these prong have to go into a specific side (i.e. positive and negative).

Do not want a nuisance to escalate into a serious problem thru benign neglect. Random black screen -- Turn monitor off then on, and all comes back fine. No loss of power in machine, no fan quirks, no overheating. Is it the Monitor? or the graphics card?

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?
i'm in desperate need of an APC backup power supply for my mac pro and acd. the old backup i've got (APC ES350) is not sufficient to power the mac pro and acd. i purchased the ES350 for my powerbook almost 7 years ago.
anyway, every time i have a power failure (it happens quite often), my entire system shuts down. which APC should i buy? i want to ensure that everything still runs for a good while so i can save everything before powering down completely.
There has been plenty of discussions in the past re: CPU, HDD and RAM temperature, but what about the power supply on the Mac Pro?
My 08' MP reports 70 degree Celsius while the 09' MP reports 35 degree Celsius, while both machines are reporting an Ambient temperature of 27 degree. Why such a discrepancy?
How about your machine?
The power supply fan in my 2010 3.2 quad just went beserk. Spinning at 2950 rpm. I suht down and restarted using the four finger solute (command-option-p-r) and it seems normal now.
What could have caused it to spin full speed? Maybe I should buy apple care . . .
I was wondering if someone could tell me what power supply is used in the current oct/quad core mac pro. Also in the Power Mac G5 and early versions of the mac pro. I am thinking of buying a Power Mac or early Mac Pro second hand and will upgrade the GPU myself and just want to know what PSU (watts) they have.

View 3 Replies View RelatedAt the beginning of the year my power supply died and Apple changed both of them. 4 months later, happened again. Now, 4 months later, it is happening again!
The power supply is plugged into a power strip with other electronics as well. The power supply keeps the laptop alive but won't charge it. If you unplug it the battery drains like normal. No light on charger, other chargers charge the laptop.
Do I have dirty power at my house that keeps blowing it? Nothing else has been effected.
Can a computer effect the charger? Please help! Still have 6 mos of applecare, but am tired of this. Would like to find solution.
The MBP's a late '08 15" unibody. I know I obviously can't (or at least shouldn't) use the Airs power supply with the MBP.
View 5 Replies View RelatedTried to wake my 24" white iMac from sleep yesterday and discovered that it was off. Pressed the button in back but no go. Unplugged and replugged, pressed the button and it fired up fine. Surfed a bit, then put it back to sleep.
Came back about 3 hours later and it was off again. Unplugged and replugged, pressed the button and nothing. Tried it a couple more times just to check, and no go.
Any ideas? I've had this computer for a little over two years. Bought it used and bought Applecare which expired on.... Nov. 16th. Beautiful timing or what.
6 of 8 processors at 100% for 24 hrs/day for nearly a week), my MacPro's "Power Supply 2" temperature suddenly rose to ~207 ?F (~95 ?C).I got a large external fan going through the desktop to bring the temperature down. I also tried to install smcFanControl to see if I could bump up the internal fan speed. Well, I could bump up THREE of the fans (I/O, CPU/Memory, and Exhaust), but it says that the PS fan is steady at just under 600 rpm, despite me cranking it up in the software to anything else (including the max, 2800, and anything less).

My UPS is flaking out, and it's a really old one I got from work that was a 'server' class UPS.
I don't want to drop $999 on the thing, as that's what an equivalent of what I was using go for. However I want my battery to last more than oh, 30s so I hope to size it right.
Any experience from anyone running a UPS on one of these things? The UPS sites aren't much help and if the tech specs are to believed if it draws 12A at 120W that's a 1440W requirement for the power supply, and that seems a tiny bit high to me, but I might be wrong.
I'm running the 2.66GHz dual core, the ATI1900XL, and 4 500GB drives in it.
I need to replace the power supply in my Mac Pro (2008) but I'm stuck at getting the small cover off. I've removed the metal plate that was under the optical drives (POV when looking through the side).
But it seems there's a small cover for the power supply that's similar to the big processor cover for the liquid cooled G5 towers. I can't figure out how to remove that.
Does anyone have a link to a manual or take-apart guide for the Mac Pro?
