New MB Pro Power Supply

The new MB Pro (Late '08) calls for an 85W power supply. Will the smaller 85W power supply from the now previous version of the MBP work with the new Pro. I've got a couple of spares I keep around so that I don't have to carry my only power supply with me everywhere I go. It would be a shame to have to buy an extra ps when I have two extras now.
I'll take advice from anyone right now. (My new MBP is ordered - 2.8 GHz model). (My previous MBP goes to my wife, and my Black MacBook will be put up for sale).

What I'm hearing here - hot body, waking up from sleep, battery drain - has has been happening with my Macbook (13") for quite some time. This seems to be more than a MBP issue! Tried taking the battery out and holding down the power button & tried cleaning the registry. Please help Apple!

Mac Pro power supply failure

Anyone have any luck repairing A 2008 Mac Pro power supply? There are two fried resistors on the board and would like to save the 300 USD for a new supply.

If I were you I'll check that nothing slows airflow around DVD location and I'll install Fan control to increase others fan speed (orange and red airflows on the drawing, mines are running at 1500/1600 rpm) this should help the whole system (AMHA), it doesn't cost to make a test.

13" mac book pro power supply weight?

What does a 13" mac book pro power supply weigh

My 85W adapter weighs 10.45 ounces (296 g) without the "duck head" corner plug inserted and 11.05 ounces (313 g) with the duck head in place. You can probably figure that your 60W adapter weighs (or will weigh) 10-15% less.

Macbook Pro power supply and grounding.

Hey Apple people. I noticed something disconcerting with the power supply on my MacBook Pro 13" (non-retina)
I have a stainless steel metal table in my kitchen. It is the same type of stainless steel table you find in restaurants.
I have my 13" MacBook Pro in a Speck See-thru case.
The MacBook Pro in it's case is sitting on a Rain Design "M Stand".
The Rain Design "M Stand" is sitting on the stainless steel table.
I am wearing a short sleeve shirt.
I am sitting on a fabric covered chair at the table.
The battery was getting low so I got out my power supply, which is the power brick with the two prong plug adapter.
I plugged this into a power strip and the other end into the computer.
While touching the case of the computer with one hand and leaning on the stainless steel table with my other bare arm. I felt a vibration through the fingers that were in contact with the MacBook Pro. I knew what was going on, and I got really concerned.
I tried an experiment.
I got out the extension cord that came with the MacBook Pro power supply and I changed out the two prong plug on the power supply for the extension cord. The extension cord has a grounding post.
When I plugged the power supply back into the power strip and connected the power supply to the MacBook Pro. I no longer felt a vibrating sensation when I was in contact with the stainless steel table and the computer.
I have other MacBook Pro power supplies and I always use the grounded extension cable with them, because it is located at my regular workstation area. This stainless steel table is located in my kitchen, and I was eating dinner and watching YouTube videos.
Just thought you would like to all know that when you don't use the grounded cable on your MacBook Pro. you become the ground.
Never using this power supply anywhere again without the grounded cable.
Thank you for your time.
Matthew Sievert

It depends on what you are doing. Yes, the power supply can get hot. This is normal.

Good evening.
I am a Hungarian citizen.
There is distributor in Hungary though here at us, but they do not have a component to it already. Nearly MSI centre it is in Germany
Well, call them back and ask where to ask for such since they don't have it,.
Or to tell the PSU specifications

Stupid question, but I ask it.
Is not for somebody into a machine like this his power-supply unit for sale?

You can try e-bay or such instead

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+.

Mac Pro power supply. Is it possible to change from 110V to 240v

I recently found out that I'll be relocating from New York, USA to London, UK. Does anyone know if it's possible change the input voltage of a mac pro from the 110 volts used in the US to the 240 volts used in the United Kingdom? or should I just rely on a step up/down voltage converter?

Hi and welcome to Discussions,
taken from the MacPro tech specs http://support.apple.com/kb/SP11
*Electrical and environmental requirements*
ENERGY STAR configurations available
Line voltage: 100-120V AC or 200-240V AC (wide-range power supply input voltage)
Frequency: 50Hz to 60Hz single phase
Current: Maximum of 12A (low-voltage range) or 6A (high-voltage range)
Operating temperature: 50° to 95° F (10° to 35° C)
Storage temperature: -40° to 116° F (-40° to 47° C)
Relative humidity: 5% to 95% noncondensing
Maximum altitude: 10,000 feet
So no converter needed, just a different power-plug connector.
And a hearty welcome to the 'old-world'

ATI Radeon 9700 Pro - Power Supply too small?

I'm having a problem with my Powercolor 9700 Radeon Pro. My system will simply not power when i plug this video card in (no power supply start, no posting beeps, nothing).
The 9700 pro card I have will work fine on another PC that I have with a lesser power supply and lesser cpu so I know the card is ok. My Geforce3 card works fine in the new 865PE computer, so it seems the MSI board/AGP slot is ok.
I've tried unplugging all peripherals (HDDs, CD, DVD drives) and still no power up when the 9700 is plugged into the power supply.
My system consist of:
MSI 865PE Neo2 FISR(v1.7)
P4, 2.8, 800fsb
512MB Corsair XMS Twinx (2 256MB sticks)
2 HDD (Western Digital, 60 & 120GB)
DVD/CD drive
CD-RW drive
Soundblaster live
2 internal case fans
360w PS
Stats for power supply:
+5v - 35A
+12v - 17A
+3.3v - 28A
Bios settings:
CPU BUS (FSB) - 200
AGP Voltage - 1.5
PCI/AGP speed (PCI clock) - 66.33/33.33
PCI latency timer - 32
AGP setting - (if this is the 4x/8x setting, I can't find a way to change it)
APIC ACPI SCI IRQ - disabled
AGP aperature - 64MB
Dynamic overclocking - off
Performance mode - slow
hyperthreading - disabled
I've tried upping the AGP voltage to 1.6 and I have disabled cacheing.
I read that some folks have recommended setting the AGP down to 4x, although for the life of me, I cannot find a way to do that in bios or anywhere else.
Does this power supply sound acceptable? Do the 9700's draw their power off the 12v circuit? If this PS is weak, then what +12v amp. should I aim for?
Does anyone have any ideas of any of issues that might cause my system to not power up like this?
Thanks for any help!

Thanks for responding Sean,
I did try upping the AGP voltage to 1.6v while only having the the 9700 card attached to the power supply. Same result, no power-up what so ever.
The other computer's video drivers are were the standard windows vga drivers. I don't think that really is a problem since I can't get the computer/power supply to even come on, let alone load windows.
What baffles me is that I have a geforce3 agp card that works fine in the neo2, and the 9700 works fine in another computer. Other then the power supply, or a problem/setting with the mainboard, I can't imagine what the problem is. The thing is, I don't want to shell out $100 for a power supply until I know that'll fix it.
thanks

Mac Pro Power Supply making noise (even when turned off)

Hi everyone,
My Mac Pro Early 2008 (Dual quad core 2,8) began to make noise a while ago and it drives me mad.
The sound is (100% sure) coming from the Power Supply. The sound is not mechanical, but electrical, like an oscillator crackle sort of.
First I thought it was the PSU itself, so I had it replaced with a new one, but that did not change the situation.
The (new) PSU makes excactly the same noise, even when my computer is turned off (but still connected to the power socket in the wall).
I've eliminated all possible factors that could create an interference (other electrical devices). I even completely switched off the power of my office, except for one power socket; the one I used to test the Mac. As soon as I connected the Mac, as soon the noise came back. So, it's got to be inside the Mac.
So my question is: if it's not the PSU, nor the power of my office, what could it be?
PS: I've tried a UPS too... but that did not change a bit.
Thanks for your suggestions!

Mac Pro power supply replacement?

We're on our yacht in Hobart, Tasmania. No access to Apple Store.
Re: Mac Pro 2006, how do I assess whether the power supply is failing?
I ask because we have experienced several times over the past couple of years the following issue. Typically in the morning I see the Mac Pro has shut down and will not startup. I go through the SMC reset procedure as per Article: HT1806. The straight forward "press the SMC Reset button" never works. Sometimes just pulling the power cord for a few minutes works. Yesterday was one of the "hard cases". None of the usual voodoo worked, so I left the Mac Pro for about 6 hours with power and all cables disconnected.
When I reconnected power the MP began a familiar 17 second cycle, both sets of Memory Riser Card Diagnostic LEDs illuminate for about 3 seconds, fans start, shutdown (repeat).
Pressing down the SMC RST button stops this loop, but still cannot startup.
Yesterday I pulled the top memory riser, left MP off for 30 minutes then when I reconnected power I could startup successfully. Shutdown, reinsert top rise, restart success.
I called Apple support, authorized a case. The tech went off to consult for 10 minutes or so, then came back and said "we think your power supply is probably stuffed".
To obtain a replacement supply here in Hobart is going to be difficult and expensive. So any advice on how to improve our assessment of the true source of this problem would be much appreciated.
The famous and helpful "Hatter" once suggested to another troubled Mac Pro owner to "leave the computer disconnected from power overnight". My experience is that the longer time disconnected is related to success, but I do not understand why. Why is overnight helpful?
PS - I've not done the following procedure yet, and because it is from the 2008 Mac Pro service manual it may not apply to the 2006 exactly as written. I'm including this info for the benefit of searchers who come along in the future:
Power Supply Verification
To power on, the computer’s logic board requires “trickle” power. If the system fails to power on, first reset the SMC as described in this chapter. If the computer still doesn’t power on, follow the procedure outlined below to determine whether the issue is related to the power supply.
Verify trickle power
Diagnostic LED 2 indicates the presence of trickle power required by the logic board to begin the startup process.
LED 2 should be yellow when the DIAG_ LED button is pressed, indicating that trickle voltage is present.
Verify Power Supply Is Providing Power
Diagnostic LED 8 indicates that the main power is OK and within regulation. Plug in AC power cord, and press the power-on button on the front panel.
LED 8 should be green when the DIAG_ LED button is pressed, indicating that the main power is OK and within regulation.
If diagnostic LED 5 and LED 6 are both solidly illuminated at power up, improperly seated power supply cables could be one cause of this behavior. Check all power supply cable connections to ensure they are properly seated.
PSS - I have recently replaced the PRAM battery.

Are you getting a chime?
The chime says the computer passed the first part of the Power-On Self-Test, and if enough working RAM and a boot drive can be found, booting is likely. Lack of a chime says something else is amiss.
The usual procedure in cases of no chime is to pretend that something is loading down the power supply. So you remove all the drives and the graphics card and everything except a minimum of RAM, and look for the chime. If you get to the chime, then you add back the graphics card so you can see what is happening, and boot to the Installer DVD. then bring back an item at a time and see when it craps out.

Help buying new GPU and power supply

Hello to everyone, I am new at the forum and also kind on new at buying gaming equipment for my pc.
Right now I am using a pc which I bought a year and a half ago but with the new games coming out I am starting to need an upgrade for my pc.
My actual gear is:
Motherboard MSI Z87 G45
NVIDIA GTX 650 2Gb
Power supply 600W
8 GB RAM
1 TB HD
thermaltake mk1 chaser
Sorry if my questions are kind of...stupid...I am thinking of buying the new GTX 970 4Gb GPU, buying an other 8Gb RAM and also getting a SSD, but the thing is that I dont know a few things:
1. Can I use that GPU on my actual motherboard?
2. Which power supply will I need for all this?
3. Would you make an other change to my PC?
Thanks a lot for your help!
Also sorry for my english, I did my best at this

Hi
Your PSU should be ok with GPU.
Yes, RAM should be identical. But even if you buy 2 separate kits of same brand, name, model, timings etc etc it may not work fine.
So preferably single kit. Like this:
As if you buy 2 separate sticks (like this):
Then you might have issues. In your case, you would be doing second option which is asking for trouble. For this, best to ask your RAM vendor for replacement once you buy another 8GB RAM stick.

12vDC MacBook Pro Power Supply

Looking for a real 12vDC Power Supply for my 13" MBP 2.53GHz Core2Duo. (12v to 120vAC) "Inverter" NOT acceptable! Total waste of energy to go from 12vDC to 120vAC then back down to DC voltage as is supplied with OEM 60w AC supply... anyone know of a source? (Airplane adapter not an option). Thanks!

Apple doesn't supply anything like this.
There are basically two options:
The solutions from http://mikegyver.com/
The hyperjuice, available from: http://www.hypershop.com/
Note that I'm not a customer of either, I just did the research out of curiosity.
