MPower Z87 Power connectors

Recently put together a new PC build using a MSI MPower z87, but my power supply (BFG 1250watt - modular) only had one lead for the 8pin power connection for the board. I tried to use a different connector that the power supply had plenty of, a 6pin + 2 pin that was the same size and shape with the +2 connected, but when I attempted to power on, the thinner wire to the +2 portion melted. Did this hurt the board? and Is it safe to run the board with only one of the two 8 pin power connectors connected? (JPWR1 and JPWR2) I do have the larger JPWR3 connected (the one above the SATA connectors).
I'm guessing I'll need to get a new power supply, the BFG one I have is a bit old, from a 2009 build, which may be why it only has one ATX 8pin connector. Can anyone recommend a power supply that defiantly has 2 (or more) 8 pin ATX power connectors?
Thanks

that may have fried the board as a 8 pin CPU power connector has different pins (a live and a ground on the side) but a 8 pin PCI-E power connector has 2 grounds there so you may have blown something on the board or damaged the PSU itself if your unlucky!
try with just one 8pin CPU power connector and and hope to hell you haven't blown something and you lucked out there and haven't damage something (It only needs one unless your using LN2 cooling and doing massive overclocks and huge over voltage's to push the CPU way above its design limits)!
also if you have damaged something and its broke your in a bad position here as you will have voided the warranty as its classed as user error because you made the mistake of convecting that!

Z97 Mpower CPU power connector

Hi I have a Z97 MPOWER with an 8-pin and a 4-pin CPU connector. My PSU only has a 4+4 pin. Is it one or the other or both? Do you use the 8-pin or the 4-pin, or is it recommended to use both? If both, which PSU do you recommend and can you use the 8-pin PCI-E for the 8-pin and 4 of the 4+4 only? Thanks.

Use the 8pin (4+4), the 4pin is for extra power if you OC to extreme.

Z97 MPOWER MAX AC power connectors... are all required?

I am building a system with an i7-4790K and the Z97 MPOWER MAX AC board. I see that it has 4 different power connectors:
24-pin (manual calls it JPWR1)
8-pin (two 4s side-by-side JPWR2)
4-pin (JPWR3)
6-pin (JPWR4)
As I understand it, JPWR4 (the 6-pin) is optional and can supply power to things.
My question is: are the other three REQUIRED? What is JPWR3? I do not have a 4-pin connector that I can see in my Seasonic X-560 Gold which is Haswell compatible according to Seasonic.

It's very nice motherboard I have to say, will serve well

Z87 XPower -- What's the third 6-pin power connector for?

I'm a happy new owner of a Z87 XPower, currently getting it installed and I'm seeing a six-pin power connector between the CPU and PCI-E slots (this is in addition to the two 8-power traditional motherboard power connectors). I'm assuming it's a PCI-E power connector but can't find any documentation about whether it's required or optional or under what circumstances I would use it. Is there any documentation out there about this power connector? It's in a bit of a problematic area as far as cable routing goes, it's next to the rear end of the expansion slots which is as far away from cable management routes as you can get and requires routing a connection over at least third of the motherboard no matter how you run it.

that 6 pin is only needed if your running 2 or more graphics cards to supply extra power to the PCI-E lanes as its draw will exceed the limits that they have causing instability!
it is an optional connector and if you only have 1 graphics card its not needed at all (I usually connect it anyway if I plan on going SLI or crossfire in he future!)

(MSI MPOWER Z87) System Won't Start

Hi, a month ago I built for myself a new PC with MSI MPOWER Z87 motherboard.
For a month it worked fine, but couple of days ago, when I tried to launch it nothing would work, OS doesn't start, fans not working including processor fan. All I see is power button button(on motherboard) lit, OC Switch Led lights (one red and one blue) and Clear CMOS (blue) blinking. Debug led doesn't work either. Can anyone help me to solve this problem, what problem do I have and what can I do to fix it?

HuntKey Green Power 550W Sounds cheap and unreliable. Haswell also requires slightly different PSU than older systems did, so if possible test something like Corsair, Seasonic, Antec (and similar with GOOD quality and reputation). You could also go to local PC shop/IT services and ask for testing your system with their quality PSU.

MPower Z87 - strange bahavioure with SSD - Unable to upgrade BIOS

My Spec:
CPU: i7-4770
Mobo: MSI Z87 MPower (MS-7881) 1.0
Chipset: Haswell Rev.06
Bios: v. 1.3
Memory: G.Skill 2x4GB XMP1.2 Dual channel
Graphics card: GeForce GTX 660
PSU: Seasonic M12II-620Bronze - 620W
HDD:
WDC WD20EARS-00MVWB0 - ATA8-ACS-SATA II
WDC WD20EARX-00PASB0 - ATA8-ACS-SATA III (MSI tested - ok)
WDC WD20EARX-00PASB0 - ATA8-ACS-SATA III (MSI tested - ok)
SSD:
Samsung SSD 840 (256GB) - ACS2-SATA III
Toshiba THNSNS128MCP (128GB) - ATA8-ACS-SATA III
*According to this: http://www.msi.com/file/test_report/TR3_2851.pdf
PC - Windows 8 x64bit
Laptop - Windows 8 x64bit
Strange thing happens yesterday, I did run above setup for over a month now without any issue (excluding HDD A2 detection that took around 30sec-45sec). I did copied some video files (3files - around 2GB) from WDC WD20EARX to my Laptop over network (SMB - or whatever proto. Windows 8 x64 uses these days) and copying just stopped - no error or anything - just progress stopped. So I tried to kill Explorer process - without success. On my laptop I couldn't access these directories with the error "Unable to access...". So what I did was to restart PC - not hard restart but windows Restart. I did same on the Laptop. Laptop boot up properly but my PC did not.
   On PC during boot I can see 99 -> 9C -> A2. At first 9C was fast, after some reboots it's taking now 30sec+, and A2 ... takes 10minutes. Strange part is that after that time everything is working fine. After Windows 8 turns on I did scan drives and non of them had an error.
   And now it's a kicker - I did copied all my data from mSATA drive (Toshiba one) and removed partition and reformatted drive - PC now starts after A2 like - 30 sec.
   But still booting up takes like 9C (sometimes its faster) - 30sec, A2 - 30sec -> 10min.
   Also I did tried to update BIOS from 1.3 to 1.5 or 1.4. After selection in BIOS file motherboard just freezes.
So questions:
1. How long it takes on MPower Z87 to detect drives for You guys? (on my 9C - 15-30sec, A2 - 15-30sec - total boot detection time is around 1min)
2. Why I cant update BIOS?
Thanks for reply
Regards

I almost brick my mobo. I did got my USB drive prepared and after reboot on "Do You want to run Mtest before update" I did press Y, although instead of running Memtest it went back to my boot chain - so boot into OS, and halfway during boot power was turned of...
Now after disabling setting up 1 drive for boot device (was that before update) I can see that speed increased.
EDIT:
Ok it did not helped at all, now its even longer to boot.
What's strange is that after 1st boot after BIOS update everything went OK == fast, then after reboot from Windows slowness starts again. No changes to BIOS settings...
I had exactly same situation with WD EARS, repartitioning helps but if this occurs again on that drive then I'm in big trouble as I don't have any more 3,5' USB HDD bay.

MPower Z87 - long board start up

Hello,
I purchased MPower Z87 board and after yesterdays assembly I stumbled upon strange board behaviour.
Spec:
CPU - i7 4770
RAM - 2x4GB G.Skill
HDD's - 1x WD EARS 2TB SATA2 - 1x WD EARX 2TB SATA3
SSD'a - 1x OCZ Vertex 90GB SATA2 - 1x Samsun 250GB SATA3 - 1x Toshiba 128GB mSATA
PSU - Seasonic 620W
Problem:
AFAIKT - Debug codes:
9C - SCSI detect
A2 - ATA detect
Long board start up. When I power up PC then I can see debug codes:
9C - 20sec -> 2min
A2 - 2sec -> 5min
So in worst case scenerio board boot up up to 5minutes !!!
NO HDD/SSD - 9C - 20sec -> A2 - 3sec = 23sec to BIOS !!!
This is on 130 BIOS, same on older one that's why I upgraded from 100.
Any idea what can cause this?
Any adivce more then welcome.
PS> Some complains:
I must say that I'm not a fan of MSI at all. I did purchase this board only because sound was better then the one in ASUS ones. My bad and now I regret it because this on my speakers won't be noticed anyways.
6xSATA slot - congratulation on adding to the Mobo L shaped connecters and not streight ones, now I can't connect upper ones when lower ones are used !!!

Well ... I don't know what debug code mean because well.. no entry in manual on this one... so. But that's not important.
Tests, now I see only A2 debug codes (9C is either super fast or not present at all) and time is related to that code:
Legacy+UEFI
SATA3 - boot very fast (SSD Samsung 840 - clean - factory state)
SATA3 - WD EARX (HDD - clean - factory state) - slow (around 5-10sec)
SATA3 + SATA3 - (SSD + HDD - factory state) - very slow
UEFI:
SATA3 connected - boot very fast (SSD Samsung 840 - clean - factory state)
SATA3 connected - WD EARX (HDD - clean - factory state) - very fast
SATA2 connected - WD EARS (HDD - partition data) - very slow
Ok.
That's deal breaker for me, as I won't juggle drives when new ones will be purchase later just to get acceptable boot speed.
In old days (Pentium 1 to 3 times) MSI product were portrayed by me as cheapest one and cr@9ies ones, now only first one changed as it's still cr@9 but cost now much more.
Going to the shop for ASUS one <- that's probably faster solution.
UPDATE:
Sometime when I press power off after some time (5-10sec) PC turns ON automatically, maybe I did turn on some "auto wake" feature - although I have all this disabled.
A2 - on drives still with long wait.

Computer won't power up if the 2x2 CPU POWER connector is plugged in

Yesterday I assembled this computer and it was working great. Played games on it and everything.
MSI K9a2 CF, ATHLON 5000+, LC POWER 550W, RADEON 3850 256MB, 2x1G SUPER TALENT 800MHZ RAM.
3 hours ago I went to the store and left 2x PRIME95 torture test running just to check for stability. After 2hours I got home only to find out the the computer has been shut down but the KEYBOARD still had a light on the NUMLOCK led.
So then I unplugged the PSU from power and started up again. But the PC only started for half a second and then the power went off.
So I pulled everything out of the board only to find out that if the CPU POWER 2x2 connector is in the board then it will not power up. Then I also took out the cpu and try to power up without the CPU and with the CPU POWER 2x2 connector in and it also doesn't power up.
Conclusion:
If the 2x2 CPU power connector is in the MB regardless if the CPU is in or not then the computer will not power on. But if the 2x2 CPU power connector is absent then the computer powers up. But that don't do me any good since without that connector the CPU can't function.
I also tried hooking it up to another PSU but it does no good. The MB, CPU, GPU, RAM, HDDS are only 2days old.
Also it couldn't have overheated since the temperatures never went higher than 50C during full load thx to Scythe Ninja Revision B cooler and also there is no smell or any indication that something could be burned. The temps were checked with BIOS as with MSI probe.
My question is is the MB the problem?? So I would know which part to send back for warranty

Do you use system stock parameters?(No OC)
Check CPU cooling system.
List PSU details(Look over PSU sticker for them)
Everything was at stock speed there was even no tweaking involved.
CPU cooling system was working great. Under load the max temperatures it had gotten was 50C. And also the CASE was opened so there was no chance of overheating. And also when I started PRIME95 I opened the window and closed the radiators which means the room temperature was about 15C celsium only.
LC POWER 550w 140MM fan.
3.3v 35a
5v 40a
12V 16a

It is probably the board right? I must know this quick to RMA it

Dx4-1548dx notebook -power connector is not working.need replacement/ fixing? any idea?

This is my second HP laptop malfunctioning as many years. Power connector (slot where you plug in power cord) goes off and on at will. Laptop totally useless if I cannot charge the battary. Look like I have to toss the laptop. May be somebody out there can help me save my computer. Thanks.

Sir,
I tried out with another charger but of no use. Also I tried out with the following steps suggested by HP:
1) Flee power discharge.
2) Remove and reseat RAM/HDD.
1 thing:
Also, sometime back, I contacted a service center for this problem, and they informed me that there is a transistor iin power line of the laptop which is not working. And we need to replace the laptop's mainboard to rectify the problem.
Thanks.

Can I get an additional power connector for a HD inside my MacPro?

Hello,
I have a MacPro Early 2009 with all HD bays full and both optical drives full. I have a Apricorn Velocity Solo x2 with 512 GB SATA III SSD and the card has an additional SATA port for my additional 2TB HD SATA III that I would like to make into a Fusion Like Drive. My question is: Is there any way to get power to that 2TB HD? Please let me know and if you have the cable I would need to purchase. Thank You,
John

Not true. There are SATA connectors that carry both data and power. There are motherboards that use separate power and data cables for SATA drives. Your question stated:
Please let me know and if you have the cable I would need to purchase.
This clearly is a request for someone here to see if there is a cable we could sell to you. That would imply you are asking Apple the question. It's not my fault that you were not clear in what you asked.
Nevertheless, my response is just as applicable to one form of cable as to another. If you have no available power connection in the computer, then you need to split one that you are currently using. This could either be the SATA power connector or it could be a Molex power connector as used on older SCSI or ATA drives.

MSI N460GTX Hawk Talon Attack - LEDs near power connectors

Hello
I've searched this forum and the web, but i didn't found the answer.
I just recently bought this VGA. It works all right, but there's 6 led on the back of the card and two of them are glowing red when power connectors are plugged in.
I just want to know if this is just an indicator that the card is receiving power thru power connectors (when i put them out, they turn off) or if it's indicator that somethings not right (you know, the red color ).
This is my pc:
MB: Asus Sabertooth i55
CPU: Intel i5 760
RAM: Kingston HyperX 8GB
power supply: Silent Pro Gold 700W
etc
Power usage shouldn't be the problem, got 2 HDD and 1 SSD and 4 fans (i used couple of web power, all of them showed value around 520W).
I've tried connect the card like 3 or 4 times (plugged with 2 separated cables from supply, connected only by "hard installed cable", conect it via one modular cable etc.), the card's 2 LEDs are always on (it's LED1 and LED2).
Thx in advance for any info.
John

New FX5900 TD128 - Power Connector?

Hello everyone,
I just bought a new FX5900 TD128 card to replace my FX5600, but before I install it, could abyone tell me what the power connector on the card is for? Do I need to connect it to the power supply, or is there some other specific purpose for it? Sorry if its a silly question, but I don't want to risk damaging my new card and the manual does not mention it at all.
Grateful for your advice.
Thanks
Orcnobeard.

I measured the current drawn from it, something like 3A from the 12V and 3A from the 5V so that's about 50W, way more than just powering the fans.
The card will work without the plug, but the fans won't spin and the card will prevent you from entering 3D mode to prevent overheating.

UMI-7772 position power connector part number

We lost an UMI-7772/7774 4-position power connector (power input connector for V, C, Viso and Ciso). Anybody knows what is its part number and manufacturer?

Hi Ben,
The power connector is a Mini-Combicon 4 position connector. The part number is 761785-01. You will have to call the Service Line to get pricing and availability. You can get these from Digikey, which might be a better option for these.

Hi Frank, thanks for the answer. The 761785-01 link is not working (probably only available to NI employees) and a search for 761785-01 on the NI website returns nothing found.

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 )

MSI MPOWER z87 BSOD on boot in RAID mode

Hello, I've just recently added a harddrive and was attempting to set up a raid and encountered this issue. I have 2 ssds - one is the boot drive, second for games, and I have 3 1tb hdd drives which I was attempting to put in a raid5. I installed the third drive today, went in to the BIOS, switched SATA mode to RAID and got an immediate BSOD before even booting to Windows. Previously, I've had the two ssd in a RAID-0 and never had this issue. The ssd are no longer in a RAID, I was hoping to only have the 3 hdd in the raid5. I'm now having to reinstall windows because the error corrupted a system file somewhere and I'm unable to repair it. Any help would be greatly appreciated.
My system is:
Windows 7-64bit
MSI MPOWER z87
Intel i7-4770k
8gb corsair vengeance RAM
2 120gb OCZ Vertex 3 SSD
3 1tb WD10ezex HDD
MSI GTX760 GPU
Rosewill Capstone 750W PSU

You cannot just change SATA modes.
