Power rating for Dual 2.7GHZ G5 coolant pump

Does anyone happen to have the numbers on voltage, current etc. for the coolant pump on the dual 2.7 ghz G5

The cord may get warm if not to UL standards ... not a good idea. As for the Mac, there might be slight voltage drop, but unlikely to be outside the tolerance range it can handle. Use a cord rated for 15 amps or better, and you should be fine.

Power Mac G5 Dual 2.7GHz Processor L.E.D indicator

I got a power mac g5 dual 2.7GHz here and it is acting weird. I found out it is the liquid cooling system that causes the problem. I took out the whole lcs unit and fix it. But when I put everything back, turn it on, there is no display and chime sound. The fan seems to run at the normal speed and when I check the processor board, there is a red l.e.d light at the bottom, which i didn't notice it before. Could that mean one of the processor is having error? Please advise me of what to do. Thanks.

Well, sorry if I didn't stated it clearly. It is not the L.E.D that we normally found on the motherboard. It is the one that on the processor board itself, which attach to the bottom of the liquid cooling unit. There is two processor board in my case, which one of it got the red l.e.d lights up. Could it be the processor problem? I can't get any display or chime sound when booting it up, even though the fan and everything seems to be running properly. I wonder if you ever encounter such problem?

Special power cord for Dual 2.5 G5?

Service manual specifies that the liquid-cooled 2005 Dual 2.5 GHz Dual Core G5 needs a special heavy duty power cord and won't function without it.
Can anyone tell me what symptoms it produces if connected with a standard cord?
thanks,
Pat

Power Mac G5 Dual 2.7GHz

I've had this G5 (2.7GHz, 1.5GB Apple RAM) since around February or March and for quite some time it made two clicking sounds and that was it. Today at around 6:40 I was just about to go pick up another G5 also a 2.7GHz for parts to replace the power supply. Right before I left, I plugged my Mac in one last time and poof, it turned on. I couldn't believe it, right before I went to replace it the G5 came back almost as if to say "not so fast".
Now what's happening when I press the power button is:
fans spin up, then slow down to normal speed
hard drive spins up
no chime
front LED only comes on when it is pressed
red LED behind the processors on logic board (not the one by the RAM)
after approx. five minutes fans speed up and after ten minutes they are at terminal velocity
will not communicate with any peripherals
only way to turn it off is pressing the CUDA or pulling the plug
Things tried:
CUDA reset
cold start
Some more info on the machine:
RAM is tested and good
DVD-RW is good
all fans run
I don't have the original disks
I don't have a monitor for it (since it never worked)
Any help would be greatly appreciated, as my iMac is really showing its age and finances are tight.
Thanks!

This is a liquid cooled Mac, It is most likely leaking/oozing something on the processors.
I recommend a complete disassemble of the machine and clean all the crud off the processors and anywhere else its found, it's important to catch this as early as possible because that stuff is so acidic it will actually eat the traces right off a circuit board!
As for the liquid cooling unit I personally:
remove heat transfer plates and clean them in an ultrasonic cleaner.
drain system and flush with fresh water, dry thoroughly, and then seal transfer plates with Permatex thermostat sealing compound (automotive store) new "O" rings would be a good idea I suppose, but I have cleaned and used the originals over with good results.
I fill mine with a 50/50 mix of prestone or equivalent
A service manual will help with disassembling the machine.
Hope this helps some

An advice for an used Power Mac G5 dual core 2.3

Hello.
I used a Power Mac G5 PCI-X (sett. 2003) 2.0 GHz, working with Photoshop. It worked great for yeras, but now, due to its typical logic board lack, it got broken and is unable to boot anymore (three times flashing power light).
Now, I use software for PowerPC CPUs, so I can't get new computers, because I should replace all the software too!
I'm going to buy an used Power Mac G5 dual core 2.3 GHz:
http://www.everymac.com/systems/apple/powermacg5/stats/powermac_g5_dual2.3.html
This is the configuration:
Ram: 5.5 GB
HD: 250 GB
SVGA: GeForce 6600 - 256 MB.
About 650 dollars.
According to you, is this a good product? do you know any issue or manufacturing fault?
Would you buy it if you were me?
Thank you!

I tried heating it (not with the hair dryer), after about 1 hour it booted and worked very well, as in past. But when I powered it off, it started again with the same problem: unable to boot and three times flashing light.
I need a working system.
Furthermore, I removed the hard disk (sata 160 GB), and installed it in a Mac Pro: but it recognized only the second partition (data). So I run the Disk Utility and gave immediately an error (wrote in red and big), writing that the hard disk had a serious physical problem, and that if the computer was able to see the disk, I had to make immediately a backup.
But the three-times flashing light error of the G5 was not given due to the hard disk, because I tried several times to boot it from the OSX DVD, also removing the hard disk, and it always gave the same problem.

I have a Apple Power Mac G5 Dual 2.3 GHz/6GB RAM/500GB HDD/Superdrive PowerPC Desktop and just bought an Airport Extreme card for it. The card is recognized but will not see the in-house network. This is a pre-intel computer. Do I need an antennae?

Dual monitor for Power mac g5 dual 2.3ghz

I wanted some advice on which monitors to get for a dual monitor setup and if its even possible to setup on my G5 or do I need a different video card?
Here's my computer spechs:
Power mac G5 dual core 2.3 ghz (late 2005)
Model: A1177
Memory: 2GB DDR2 SDRAM
HDD: 250GB
OS X 10.5.8 Leopard
The only thing I run on this is logic studio 8. I wanted to expand my setup but not sure how.
Any advice is greatly appreciated! Thanks

It depends on which video card you have installed, though not much. Whichever card you have installed, you should have two DVI outputs available. With the minimum 256 Meg VRAM, you should be able to support two 1920x1080 monitors without a problem, and the "HD" monitors are getting very plentiful and dropping in price. Were I to buy today, I would make sure to get an LED monitor, as that flavor should have a longer overall life than a florescent panel monitor. You can find monitors in 23" dimensions for under $200 a pop, and more 27" monitors are showing up at a slightly bigger bite.

I just purchased a 3TB Time Capsule. I live in Italy and have 220V power. The Time Capsule is rated for that, but the cord says 125V. Can I use this cord with an adapter, or do I need to buy a new cord at an Italian store?

Due to the kind of plug used the US power cord is rated at the 125v value.. and legally we cannot advise you to use on higher voltages.. although I have never had issues in Australia.. 240v.
But adapters from your Euro power plug to US are generally ugly .. unsightly things.. and often sit high above the socket and are none too stable.. I agree with Bob.. just go out and buy a standard figure 8 power cord.. check with Apple in Italy for a white one.. if you are going to have it on show.. black are far more common. Or even check ebay for a standard power Apple power cord as a number of items they sell use the figure8 socket.

Need help finding a good monitor for a Power Macintosh G5 Dual Core (2.0)

Hi
I've owned Macs since the 90's - the past 7 years have been using Imacs... I'm going to purchase a Power Macintosh G5 Dual Core (2.0) with the Nvidia 6600LE card. Whats a decent monitor for it? It's DVI output only as far as I can tell - I want at least a 22 or 24 inch monitor and want a fairly inexpensive one as I'm a poor man (Social Security disability). Can anyone suggest one - I can't tell what screen resolutions are optimal for the card (googled till my eyes hurt) if I knew that I could start hunting CompUSA, Sams Club, etc.

Check out newegg.com. I just got the same G5 you have this past summer and a couple months ago finally decided it was time to ditch the old 21" CRT Viewsonic Ive been using for years.
I picked up a 21" Acer widescreen HD LCD on sale for $119.00 from newegg and could not have been happier..
Ive never bought anything from Acer before but its so far got no complaints from me other then, the DVI cable they give you is the wrong type to use with your G5's video card. Lucky for me it had a DVI-VGA adapter so I could get running. Its running just fine at 1900x1200 without any dual link DVI connecter.
One thing I like about newegg is you get to read user reviews and they are not afraid to tell you if something is bad. Theyve always got different models and brands rotating on and off sale so check em out and make sure you check the reviews and you can find a killer deal.
I think the Viewsonics I looked at in the same size were around $199 or so.. I wouldve got one but Im a broke and jobless kinda guy nowadays so had to get one as cheap as I could..

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

Is there no external power option for new MacBook pro with dual core?

Is there no external power option for a MacBook pro 17 with dual core. Apparently apple doesn't offer one and I can't ind any who does

Given that the stumbling block to more flexible power options is the infamous patent-protected MagSafe connector
The funny thing is, I've seen loads of cheap "replacement" MagSafe adapters on eBay, Amazon and in local shops. On eBay, they cost (new) about $26, on Amazon I've seen them as cheap as $17!!, against the $80 that Apple charges. And apparently, it's not worth it to pursue the matter, it's been going on for more than a year now.
made of pure unobtanium and guarded by packs of rabid lawyers, someone is shooting themselves in the foot by making the power bricks so frail that the secondary damaged goods recovery market grows without bounds...
I really dig that unobtainium reference :-)
What I've found is that the bricks aren't so frail but the DC cord is! Apparently that's difficult to make resilient, with the characteristics that Apple wanted them to have. Out of every ten broken MagSafe adapters I've seen, only two actually have failed electronics, five have frayed DC wiring and three have a broken MagSafe connector.

Best video card for a Power Mac G5 Dual 1.8 GHz

What is the best video card I can upgrade to with my Power Mac G5 Dual 1.8 GHz?
Thanks,
Jeff

Hi-
The best is probably the one that you can find..... getting hard to find Mac 8x AGP cards.....
Best OEM cards are (were) Radeon 850XT, Radeon X800XT, Geforce 6800 Ultra and Geforce 6800 GT, in order from fastest.
X800 vs. others
Now, most options are the above, used, or, flashed PC cards. PC cards include the above, but have one faster than even the X850XT- the Geforce 7800 GS.

CPU fan recommendations for dual 800 Quicksilver

It never rains but it pours.
Just a few hours after posting about HD heat issues my CPU fan has gotten really noisy with a slight rattling noise. Yes, it is the CPU fan. Maybe it's the hot weather we are having causing something to expand, or maybe the cleaning I gave it yesterday with compressed air pushed it over the edge. Anyway, I removed the fan, lubricated it with one drop 3M oil under the sticker, replaced it. All dust and dirt is off the blades. I have poked and prodded it to see if there were other items vibrating (e.g., the famous screws touching something), but nothing changes. The sporadic rattling (sometimes disappears for half a minute or so but usually there) really suggests to me that a bearing might be going. At this stage I think it is time to go shopping for a new fan.
This is a dual processor machine of the early QS series so it's like a toaster inside and I'm not sure if any of the standard QS fan recommendations apply to a dual. Of course I want everything - high CFM and silence. I found a lengthy discussion from last December talking about a single processor replacement but I thought I'd solicit current recommendations, especially for dual processor.
Thanks

The specs aren't too hard to find; I just searched: " Sunon PMD1206PTB1". Google brought me to a Sunon site.
http://www.tmcscsi.com/Sunon.shtml
the above link doesn't seem to work as a link, but when I type it into my address bar, it works fine. Go figure!
which tells all. The KDE1206PTV1 fan is a different series and rated at 23.5cfm and 33.5 dBA, which I think we knew; it also runs somewhat slower and draws about half the current. More importantly, there are probably half a dozen 60X60X25mm fans of either the PMD or KDE series that would fit, and would push more or less air at more or less noise. What it doesn't tell is what your ear would call an acceptable compromise. In general, of course, more cfm, more dBA. It also doesn't tell how these stats compare to other brands; I ran it all down at one time, and it's a rather laborious process, but it can be done. I didn't have any frame of reference, so it was all just numbers to me; I set the whole matter aside until just now with your inquiry.
I wouldn't worry about the connectors too much; I fit QS fans to the DA model and wind up connecting them with Molex plugs and no problems. The replaced SilenX fan had three wires, of which only two were used, and it worked. Most PCs use a third wire to turn the fan off or on, or up and down, or something - which Apple doesn't. N.B. If you use the Molex connector, you will note that the red (5v) wire plugs into the yellow (12v) socket; not to worry - it spozed to. The PMD fan I got came with two wires, bared at the ends, but no connector(s). I wound up jury-rigging the connexion. PC accessory houses that sell fans also sell wire adapters of dozens of configurations, just search. My two favourite such houses are Xoxide.com and pcToys.com. I think I got the Sunon fan(s) from Allied Electric (alliedelec.com) for about $12 and $12 s&h, which is a minimum figure. You can ship multiple fans for that.
Sunon says its fans work on the Mag-Lev principle, so lubrication wouldn't help much. What would hurt would be an unbalanced fan, so it might help to clean the crud off the blades - evenly, if possible.
I keep wondering what a slot fan would do to cooling and noise, but that may be a thought better postponed. First should be getting the CPU acceptably cool. I also understand it helps cooling if you clip some of the grillwork in front of or behind the fans (power supply fans, especially).
Just a few thoughts ..... Jon

Power Mac G5 Dual 2.0 GHz Model #M9032LL/A - Is it usable?

I have a lead on a used Power Mac G5 Dual Processor, Model #M9032LL/A. I'm trying to determine if these models were any good - any known issues, any recurring problems? I know that it's not liquid cooled - any problems with overheating? I believe this is one of the earlier G5s, manufactured in June 2003. This one comes with 2.5GBs of memory and the price seems fair. It will be used as my son's primary computer - he does music as well as the normal high school work. Any thoughts? Thanks!

I use this same machine at work. Bought it when it first came out in 2004. This baby is a work horse, used for a minimum of 8 hrs. a day since I got it and not one problem. Its also easy and cheap to upgrade (RAM, Graphics, HD and Optical, if needed). We can easily afford to replace it with a new Intel machine but we choose not to because of this machines speed and stability. If the price is right, do it.
