ATX 8-pin Power Connector: JPWR2 12v power to CPU

MSI P67A-G43 (B3) motherboard, COOLER MASTER Elite Power Supply, Intel Core i5-2400 Sandy Bridge 3.1GHz
I have two 4-pin power connectors coming from my power supply. Should I connect just one to the top of the socket as shown in this link
http://www.mediafire.com/i/?91bhhi1myt9f5zo
or should I hook both of them to the 8-pin socket?
I am waiting for a replacement for my i5 cpu. My new build wouldn't boot and gave a 5 beep code and then would immediately shut down. No display on screen. I'm hoping it's not the motherboard.
Thanks.

It should work with only 4, but if u have 8 pin connector coming from your power suply i would connect the other one too and be done with it.

Adding third party video card to P700 - no power connectors? New Power Supply Question...

Hello,
I have a new P700 30A90012US with a 650W PSU and that didn't come with a video card. I am planning to use it as a DAW and for occasional gaming via a dual boot.
I wanted to put in a third party video card like a nVidea 970 but there aren't ANY connectors for video cards that I can find inside. The monitor I have is a 3440x1440 monitor. I have ordered a second 2609 Processor and RAM from Lenovo and have the following questions:
Once I install the second processor, how much wattage for a video card is available to me?
I understand that the 3rd party video card isn't supported but how do I attach power to it?
If it is required that I have to replace the 650 power supply with an 850, does it come with the required cable? I only see a 4 pin connector on the mobo that is unused (and I believe it is for additional hdd)
I tried searching but I am at a loss.
Thanks,

Your config isn't really power hungry (and the 85W CPUs help a lot). Though technically outside of the official spec, I think you could easily go to a 225W card for graphics if you had the connectors available to support it. I'll double check the current when I get a chance, but it's probably really low risk if you want to convert your single 6-pin connector to dual 6-pin or a single 8-pin (via a dongle) to get to 225W TDP if you wanted to.
The PSU design is very modular, but unfortunately it's the aux power cable drops that kept it from being an easy field upgradable part. I always recommend that people buy the larger PSU if they ever think they'll be doing any upgrades in the future just to make sure they are covered.
And like I said if you're comfortable working inside the system, it's not impossible to upgrade that cable drop on your own if you want to go up to the 850W. You'd have to get the cable and PSU, but after that it would require removing the motherboard and PSU, cutting some cable ties and routing the new cable, then getting everything routed correctly such that the motherboard reinstalls cleanly.

K7N2G and 12v power connector

Hi all,
Do I have to connect the 12v power connector from my power supply to jpw1? Also is anyone experiencing any problems with lockups when pressing the reset switch?

yes,and no here

12v ATX Power Connector

Ive just modded my new power supply to fit my bespoke case, but the ATX 12v power connector(4pin) has a fault.
when connected it causes nasty noices through the speaker system like its got a break in the wires from the PSU to the connector on the board.
The question is......
I havent got it connect at the mo, the pc is running ok so do i need to use it??????

cd-r/dvd combo
2 case fans
neon lite
PS cant take the PSU back its got no case anymore

the 20 pin atx has 5x 5v feeds but only 1x 12v
this is because in the past 5v feed the vga card and the cpu
now modern vga cards lie yours feed of the 12v as does the cpu
now a pin on the atx moules i rated to 6a max giving 72 watts max
many amd cpu pull that on their own
this is why these and other boards have the extra 2x 12v feeds

Does anyone connect the ATX 12V power connector?

Does anyone connect there power connector to the ATX 12V connector? The 12V power connector is used to provide power to the CPU, or is that what the 20-pin connecter is for? The 12V connecter is usually next to the socket and has 4 pins. thx for the help 8)

plug the 4 pin in it should be more stable
update bios as well

HPE-210f, one 4-pin ATX power connector support USB card ?

For my Pavilion Elite HPE-210f, Product # BK169AA#ABA, HP support, Motherboard Specifications, H-RS880-uATX (Aloe), shows my PC as offering "one 4-pin ATX power connector."
Does that "ATX power connector" meet the requirement for a "5V 4 pin connector" to power a USB 3.0, 4-port, PCI-E Express Card that I wish to install? With no free PCI Express x16 slot, I can't mount a GigaBit Ethernet card, so the USB 3 card seems helpful, apparently faster anyway, for connecting to the SS-USB port on my Gigabit switch.
How do we decode/understand the P-codes (ergo, P3, P5, I think I recall) on the power connectors on cables from the power supply?
Also, the PC board specs promise "Three PCI-Express x1 (Gen 2.0)," and "One PCI Express x1 minicard socket (Gen 2.0)." I cannot identify the minicard socket, but I do see three identical PCI-Express x1slots, with only one occupied, so the slot requirement looks fulfilled.
Power cable OK? Comments, advice? Thanks!

No, the 4-pin ATX power connector is for the motherboard. If you have a link to the USB card, send it. Some use a 4 pin peripheral (molex) , some use a 15 pin Sata power lead.
I am sending this link. It explains all the various connectors of the typical PSU.

Quick question on 8-pin ATX Power Connectors

First, I am very VERY new at building systems. I was building a Athlon 3800+ X2 system with a MSI RD480 Neo2-FI motherboard and ran into a 8-pin ATX Power connector. Unfortunately, the 450 Watt PSU that came with my Antec Sonata II does not have that plug. The Computer Renassaince guy told me to just plug the 4-pin into the mobo and it would work (personally, I think he is nuts). Question, is he right? If not do I have to buy a new PSU or can I use some type of adapter?
Again, realize I am very new at this. Thanks in advance.

You mean that there is a 8 pin connector on the mainboard is for cpu power supply and your own power supply doesn't have such a relevant
connector. If in that case, then the guy who told you to use the 4 pin connector is right, most of the time, it would work. You don't need to buy another power supply. Please firstly have a try.

KT2 COMBO, Is 12v power Connector Needed?

Just Bought a "KT2 COMBO" to upgrade mi good old 6330 lite, and add some 2100 DDR Ram, and a new xp processor ( 2000+ ).
The problem is I'm using the same case, and the power supply in it has no 12 V ATX Power connector.
In the Quick User Guide, it refers to it (p 2-9), saying it's to provide power to the CPU.
Would the system work ok if I use only the main power connector?
Has anyone tried using it this way?

If you don't have stability problems it's probably fine.
You can buy an adapter to allow you to convert a mulex ( like you plug into an HDD ) to the 4 pin 12V plug.
If you don't have one you might try looking in local shops for butn out PSUs that have them, cut the wire and solder it to your PSU's output ( yellow to yellow, black to black )

K7T Turbo2 12v power connector

I connected the 4 pin (jpw1) 12v power connector on my mobo to my 250 watt PS and the video dropped out. If I disconnect the 4 pin connector, it works. Should this be connected? If not, why is it there?

That connector is used to supply extra power to the cpu. If the system works fine without it being connected, no need to connect it IMHO.

D10 - Voltage of 10 pin and 8 pin power connector

Dear All
I got a D10 here, the power supply suddenly stops to work this afternoon, I have already called my brother in US to find me FRU parts. But this might take one week or longer, I borrow a big 850W PSU from my colleague, but it doesn't have 10 pin and 8 pin power connectors on it. I know the voltage used by computer internally are 3.3V, 5V and 12V. Just wondering, what voltage shall I supply to these 10 pin and 8 pin connectors?
I sent the demaged one for recycling,..
Thanks in advance
Regards
Andres
Solved!
Go to Solution.

If you're talking about the 2x4 and 2x5 connectors used to power video cards, those are +12V.

2nd 8-pin CPU power connector on Big Bang XPower

I am currently using both 8-pin CPU power connectors and am wondering if it is really necessary with my current overclock. For all the BB XPower owners let me know your thoughts on this.

When doing early tests with the BB Xpwr, I only had a single 8 pin CPU connector ( PSU was single +12V Rail). Since it was not necessary but recommended, I purchase an 8 pin Y cord manufactured by Athena. It worked perfectly until I got a newer double cabled 8 pin PSU (Single +12V rail Corsair AX1200). I also supply power to the boards 6 Pin JPWR4. As Jack says, if the PSU has the connectors (or use the Athena), fill 'em up with power!

KT880 delta 12v power connector

I just purchased a Kt880 delta and see that it has a 12v cpu power connector which my atx power supply does not have. do I need this connector?. The msi web site says it is used for p4's.

Yes, a new PSU is in order. The KT880 board relies heavily upon the 12V and 3.3V, while (like many newer boards) largely ignoring the 5V.
As mentioned previously, avoid cheap PSU's, as they cannot always deliver the power needed for modern systems. Many cheap PSU's use a high amp rating on the 5V rail, to claim they have a PSU that can deliver more juice, but they simply cannot run a newer system.

Information on Sun Ultra 5/10 PSU regarding 6-pin AUX power connector

I've been messing around and reviving my old Ultra 5 and Ultra 10 machines. I've been considering upgrading the ATX power supply to something more modern, quiet, and 80Plus. From the hardware documentation, I have already confirmed that the 20-pin ATX main power connector is exactly as specified for ATX v1.3. So, any modern ATX PSU with a 20-pin or 20+4-pin main power connector should suffice in that area. However, on the Ultra 10, the 6-pin AUX power is also used. I'm guessing this is probably to power the UPA graphics stuff (Creator3D/Elite3D/etc.) since the Ultra 5 has the connector on the motherboard but the PSU doesn't supply any power to that 6-pin.
Looking at the 6-pin connector, it is orange-orange-orange-black-black-black. Typically, on PC hardware, this 6-pin is red-orange-orange-black-black-black. Does this mean Sun used a slighty different 6-pin AUX? I.e., instead of 2x 3.3V + 1x 5V line, does Sun use 3x 3.3V lines? I suppose I can just measure it, but it would be nice to have a 2nd opinion just so when I do measure it, I have some confirmation of what i'm seeing from someone else.
As FYI for anyone else, the U5 with a 10K RPM SCSI disk and 'glm' based SCSI controller draws only 60-65W, while the U10 with Elite3D draws almost 130W!!!! I'm hoping i can find an appropriately spec'd modern PSU since the power requirements on these things are so low!

four of the eight connector receptacles are blocked with a removable piece of plastic. Why is this?
You can safely remove the cap and use the additional four pins, if your power supply has a proper connector. Four of the eight pins are covered to avoid confusion with PSUs that only have a 4-pin connector.

Problem 2: PSU-mainboard compatibility
The Enermaxx LIBERTY DXX 620 SLI (ELT620AWT-00) is listed in the MSI PSU compatibility list. It does not have a -5V-rail either. You should be fine.

Problem 3: PCIe power connector
Use one of the 6-pin connectors of your PSU. That way you can make sure that the power load is balanced. Those adaptors are usually for PSU that do not provide 6-pin PCIe-plugs.

Do i hook up both 6 pin power connectors?

Hi everyone,
I have the N470GTX M2D12 graphics card. It has 2 places next to each other for a 6 pin power connector. Do i hook them BOTH up?
I do have two,and they have a small 2 pin connector hooked to them. What are they (the 2 pin connectors) for????
Thanks in advance on any help you can give me.
