Help a newb connect his power supply cables to the MSI Z97 XPower AC?

My Background
I am mostly a software kind of guy, and this is my first time building a computer. I saved lots of money, did lots of research, and picked my parts.
So far, I've installed my CPU & Fan to the Motherboard, and mounted them to the case.
Now it's time to install my Power Supply. Mounting it to the case is easy. The problem comes when I have to connect the cables. The manuals don't explain the purpose of these cables or provide "step-by-step" instructions.
I've been searching for over an hour, but can't get a clear idea of what I'm supposed to do. So I'm hoping someone can help me here.
Hardware
Motherboard: MSI Z97 XPOWER AC
Power Supply: Seasonic X-1250
(EDIT: Forum does not let me link to the manuals, so for anyone who needs...please look online)
Problem
On page 29 of my motherboard manual, it shows 4 different power connection slots (JPWR1, JPWR2, JPWR3, JPWR4). Unfortunately, it doesn't explain what goes in them.
On page 59 & 61 of my Power Supply manual, there is listing of all the key cables.
I think the "Mainboard 24/20 Pin" cable goes into the "JPWR1" slot.
- So I am mostly confused about the other slots (JPWR2, JPWR3, JPWR4).
- Also, it's confusing that there are two CPU cables called "CPU 8/4 Pin" & "CPU 8 Pin".
Can anyone help me?

Hi guys, I have a follow-up question about my Seasonic PSU "PCI-E cables".
The way my PCI-E cables are designed is...
There's one end which is a single cable with a 12 hole connector...that goes into the PCI-E port on my power supply.
But then the other end splits out into two different cables, with each having a sort of 6/2 connector.
So regarding the end that splits out into two different cables...
Can each be used on different PCI-E devices?
Or is it the case that because my PSU has 3 PCI-E ports (and 3 of the cables I described)...that only 3 PCI-E devices can be powered?
all can be used however you plan to use them! all them connectors are tied to a single 104amp +12v Rail so they are getting power off a single Rail!
as long as what you plug them into do not exceed the Rail's ratings your fine (would take quite a few Graphics cards to get above that) (basically if it works it works) (would take like 2 R9-295x2's or 4 R9-290X's to get to that point)

My Macbook Pro with Remakes funny noise when connected to power supply cable and no other response. The best description of the sound I can give is the buz the computer makes on startup. Sound goes on and off while connected

I am new to the Macbook community. I own this Macbook since 10/2012.
My Macbook Pro 15 with Retina Display suddenly totally stopped responding. No display, no activity on keyboard. When I connect power supply cable, the Mac makes a noise as if it is starting up, but this lasts a second and this sound comes and goes the whole time the power cable is connected.
Any advice?
Thanks!

HT5219 I have a macbook air (mid 2012) and a thunderbolt display. Do I absolutely need to connect the power supply together with the thunderbolt cable ? I found that the screen won't wake up if only the thunderbolt connection is plugged.

I have a macbook air (mid 2012) and a thunderbolt display (27'').
Do I absolutely need to connect the power supply together with the thunderbolt cable ?
I found that the screen won't wake up if only the thunderbolt connection is plugged. Is this normal ?

I just got my ATD and late 2011 MBP up and running. I've not tried running without the power adapter from the ATD plugged in, but I just tried and didn't have any problems with the display not waking. You may want to take your query to the ATD forum - https://discussions.apple.com/community/peripherals/thunderbolt_display - perhaps someone there has experienced a similar issue.
Good luck,

LB1815, welcome to the forum.
If I understand your problem correctly, this is the connector that you need. It converts a single SATA power cable to two connectors. This allows you to connect two drives with on cable. There are many other brands available on Newegg. This is just one example.

My MacBook Pro will not powerup (even when connected to power supply).

My MacBook Pro will not powerup (even when connected to power supply). The caps lock key is the only light on.

Hi PatB11902,
Thank you for visiting Apple Support Communities.
If your MacBook Pro does not seem to power on, but the caps lock key will light up when you press the caps lock key, you are likely seeing a video issue.
There are several steps that can help troubleshoot this behavior, found at this link:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
Start with these steps:
Reset the system
You can reset the Mac's parameter RAM and SMC.
Start up in Safe Mode.
If your Mac does not start up normally after these steps, here are some additional tips that can help:
Troubleshooting: My computer won't turn on - Apple Support
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.
If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).

Why does my FP-1600 take a 24V .5 Amp Power Supply and drop the Voltage to 11V at .5 Amps?

I have a FP-1600 connected to 4 FP-TB-1 bases. 2 FP-AI-100, 1 FP-TC-120, and 1 FP-AO-210 modules. I am powering the FP-1600 with a 24 V .5 A power supply. There are no devices currently connected to any of the modules. The power supply should be supplying 12 W, which should be enough to power the FP-1600 and the 4 modules according to the power requirement calculation in the manual P = 7 W + 1.15*#modules. When I install the third module, the FP-1600 stops communicating. Checking the power supply I see that the voltage drop across the power terminals on the FP-1600 is only 11V and then measuring the current being drawn it is .5 Amps, which is only 5.5 W, not enough to power the devices. When I unhook the power supply and measure the Voltage it is 24 V.
Why is the FP-1600 dropping the Voltage to 11V? Should I just purchase a 12V 2 Amp power supply?
Thanks for any help
Jeremy

Hello jqk,
You got it figured out. The maximum current that can be drawn is .5 which is too small. As the current being drawn approaches the maximum allowable current, the voltage will begin to drop. Eventhough the current you measure is .5A, the fact that the voltage is 11V means that the circuit requires more current to function properly.
As a rule of thumb, you want the maximum current your power supply can deliver to be at least the double of the system's maximum current consumption.

How do I scan and email documents on my canon mx870? I have a MAC OS X 10.7.5 and it is connected with a usb cable to the printer. Thank you so much!

Hi, I have 10.6.8 and an HP printer so it may be slightly different but I'll give it my best shot:
Go to System Preferences.
Click on "Print & Fax"
Near the top of that page you should see "Print" and "Scan" options. Click "Scan"
A button appears that says "open scanner"
The settings are different between the different scanner models so I'm not sure what the next window will look like, but it should be pretty straightforward from there. It will scan to a JPEG image which you can attach to an email. I hope that helps! Let me know if there's anything ense I can help with.

Help with kernel and possible power supply problem

From 2 days after getting my imac I had my first Kernel restart. Since then I have done everything apple has asked. Ram resets and removing everything from the imac itself To find that it still had a kernel problem. The error messages are Plugnplay or spinlock usually but have also been various ones such as Kerneltask. I have done a full reinstall of the operating system and only installed official apps from apple store, adobe flash and silverlight and next day was a kernel error for plugnplay.
The imac is currently in the shop for a look at but 2 phonecalls back saying they have had no evidence of errors. In fact its perfect for them. The kernel is usually a few hours from turning it on but can go all day fine But they have had the imac almost a week.
So the only thing I can think of is if it works great for them is either they are really lucky or have a different electricity supply/cable. So this leaves me thinking as stupidly as if it is working perfect for them then could it be a surge protector or power supply causing the random crashes? Even something to do with the power lead itself? I am really pulling at strings and going crazy because the only other thing I have been told to do is spend a week at a time just adding one thing at a time till the error shows itself so could be months and months.
i know kernel issues are historically hard to diagnose but any help would be great. At the moment i have a £3000 paperweight on my desk thats only turned on a few hours a day because I have no faith in it.

Hi Joel,
For the external drive issue try resetting your firewire ports.
To do this, shutdown and disconnect the firewire devices from your computer and from each other if there is a chain of them. Now disconnect the power cords from both your computer and from the firewire devices. Wait fifteen minutes. Connect up again and see what happens. The FW ports on Macs have a 'self re-setting fuse" that requires all power to be removed for a period of time for re-activation.
You may also want to try a PRAM reset if that doesn't resolve the issue. Sometimes this can also be implicated in FW problems. Shut down. Hold down the command option p r keys. Now start up, keeping the keys mentioned depressed until the chimes have sounded three times.
Cheers
Rod

Power supply cables

In the upper expansion bay of the G3 DT case the power supply has some cables coming out of it. There are the larger 4-pin sockets for hooking up hard disks. Then there's a smaller 4-pin connector. Does anyone know what that smaller 4-pin connector is for? Could it be used for an extra case fan or blower?

I also believe the small 4-pin connector is for powering a Zip drive.
If you are looking for a power connection for an extra fan or blower, most come with a standard 4-pin connector for convenience. If you are out of 4-pin connector power out plugs in your Beige, simply buy a 1 into 2 plug converter. They are available in places like CompUSA, Rat Shack, and others. Also available on line.
You are dealing with low voltage DC power, so there isn't a problem in splitting the supply from one into two.

To connect a Power Supply over RS-232 in LabView

Have a nice day,
dear friends, I have done some basic programs before in LabView, my project is now to connect Agilent E3631A DC Power Supply serially and sending/recieving data(my aim to change input voltage from the computer without touching the hardware device).
I actually already connected the Power Supply to my computer ,I also downloaded driver of it from Agilents web site.
So the only thing is now to establish the connection in LabView.
hmmm. can you please tell me what to do now ? I have no idea if I should choose VISA or DAQ or sth else.. how can I let the LabView to send a new voltage to the hardware.
With best wishes

After installing LabView 7.0 and VISA Now I have concrete questions. Do I need some more program to install ? ( drivers I already found from ni.com )
You should have everything you need to do serial communications installed. The drivers you downloaded should help you get started with your applicaition, so I'd install them as well.
first of all I installed LabVIEW Evaluation version 7.0 , and I can`t open sources which are written with ver. 7.1 , how can i handle this problem ? ( because somebody sent me some codes which are written in 7.1 and I definetely want to see them )
You can save VIs to the previous version only. So will need to have somebody save the code to 7.0 for you.
second; should I use VISA or IVI ? whats the difference between them ?
At this point, I wouldn't worry about IVI. The drivers you downloaded are probably "IVI Drivers" but use VISA to communicate with your instrument. If you want to know a bit more about IVI in general, just do a search on ni.com for "IVI".
third; lets concider that I use VISA . From the IO Config menu, I choose COM 2 and VISA interface name is than ASRL2(automatic). And than from VISA Assistant, I choose the place of the driver of my Power Supply. Up to now everything seems to be ok. what is the next step after here ? Do i forget some configurations?
The first step is to initialize the port and instrumnet. If you look on your functions palette from the block diagram, there's a sub palette named "Instrument I/O" and a sub palette of that one named "Instrument Drivers". In this drivers palette, you should see a palette for the drivers you installed for the power supply. There should also be a sub palette in there named "Applicaiton Examples" that can help you get started. There should be one or two examples that will allow you to control the power supply, and you should be able to open the block diagram and see how it's put together.

My macbook model 7.1 will not start up unless connected to power supply even when it is fully charged. Does anyone know the cause of this?

I have a 4 year old MacBook 7.1 that has worked wonderfully until today. I went to turn on my computer and it would not do so until it had been plugged into the power supply, and it was fully charged. Can anyone suggest what to do to fix this? DO I need to take it to an apple repair tech? Thanks

Hello ssamaro13,
I definitely understand your concern with your battery not powering your MacBook when the power adapter is disconnected. I found a couple of resources that I think might help with this.
The first thing I recommend is resetting the System Management Controller (SMC) on your MacBook:
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
You can find the full article here:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/ht3964
If your battery is still not powering the computer when disconnecting the power adapter, the next thing I recommend is troubleshooting your MagSafe adapter using the steps in this article:

HT201263 iphone has completely dead, it wont connect to power supply or PC and won't re charge

My iphone 4 has completely died - it wont connect to the power supply, wont connect to PC nothing - any suggestions ??

Maybe the fact that it's dead has something to do with it...?
If a reset didn't work, make an appointment at the Genius bar and let them look at it.

Need a piece for my power supply cable

So my mag safe power supply for my Macbook Pro has the two little "hooks" that pop out and allow you to wrap the cable around them for travel. One of the hooks broke and during the process of trying to get it fixed through Apple, by replacing the hook, I was advised you have to replace the whole thing.
I was wondering if anyone knew any place to get these little guys or had an extra one lying around that they would be willing to sell via a Paypal payment.
Thanks!

Alternative suggestion I gave to one of my clients: buy another power adapter, then use the "broken" one permanently at your desk. So rather than rushing out of the house, forgetting to pack your charger, instead leave one of the chargers in your bag. When you get home, you plug in to the "permanent" desk charger. The one on the desk would never be coiled up, or coiled up in a different way with wire ties or something. And if the charger is under your desk, well, out-of-sight, out-of-mind.
I've done this for years, ever since that first time I forgot my charger and blew my school assignment because no one on campus had a compatible charger I could borrow. While it is an additional expense, it's also a comfort that when I break the charger, I have an immediate spare, or have a second charger for troubleshooting.
