990FXA-GD65 MAINBOARD POWER CONNECTORS

hi,
I am building a new system using your 990FXA-GD65 board and an AMD 8320 chip.
I am at the part where I must connect power connectors. I see that there are 3 connectors: JPWR1, JPWR2 and PWRCONN1.
My Power Supply has the 24-pin cable for JPWR1 OK. But it does not have the 8-pin cable for the 8-pin JPWR2. It only has 2 x 6-pin connectors labelled PCI E1 and PCI E2 and another 2 x 4-pin connectors labelled CPU1 and CPU2.
The power supply I have is a OCZ 700W unit (OCZGXS700) and its about 4 years old.
What to do? Can I just leave the connector JPWR2 unplugged? Or will I have to purchase another Power Supply?

connect both 4pin CPU ones to JPWR2 as that is a 4+4 connection and if you look at the pins its 2 identical pin sets as a 4 pin so use both.

990FXA-GD65 Power Supply Help

Hi there, I am currently looking to build a new computer, though I am trying to make sure before ordering the parts that my power supply will work.
I know that the power supplies listed under the motherboards tested section on it's information page is probably the best way to confirm, though I was curious if someone may be able to give me a hand as I would not like to buy a new power supply if the one I have is actually sufficient. I have done some online calculations to see if the wattage is enough, and it has come back with positive results, though I am not sure if the ampage will be enough for what I am wanting to run.
Here is a list of the current parts that I am looking to run in the new system:
MSI 990FXA-GD65
MSI Nvidia Geforce 9800G2 1gb 800 MHz
Seagate Barracuda 7200.12 ST3500418AS 500gb HDD
Kingston KVR1333D3N9K2/8G 8gb Ram
The power supply that I am looking to use is the TR2 RX-850 ATX 12V 2.2 14cm Fan.
+3.3v/30A
+5v/28A
+12v/18A
-12v/0.8A
+5vsb/3A
the +3.3v and +5v have a combined max wattage of 180W
the +12V's have a combined max wattage of 720W
the -12v has a combined max wattage of 9.6W
the 5vsb has a combined max wattage of 15W
I am looking to buy the parts for the computer in a bundle, and this would be some helpful information to help with my purchase. I am trying to stick MSI for as much as I can, though unfortunately there are no MSI power supplies! If anyone has knowledge on the basis of my request, or just general knowledge to share about choosing a power supply, I am always open to hearing more and expanding my personal knowledge of computers.
Anyways, thanks for reading everyone, I look forward to your responses!

Thank you for the quick reply, I appreciate the fast response.
Out of curiosity, would a second MSI nvidia Geforce 9800 G2 1gb card be something that would add too much strain for the power supply? In the future I would like to pop in a second card, though I don't want to burn anything out. Also, are power supplies generally universally equal for their ability to hook into a board, or do some board require different cords and such?

MSI P55-GD65 Active Phase Switching and power connector

1. The APS LEDs on my board are alway blinking, is this normal or is there something wrong with my PSU?
2. The 8 pin power connector for the CPU: I have a 4 pin cable and and a 8 pin cable. I tried connecting the 8 pin cable and the CPU temp was very high (70-75 Celsius) and my PC shuts down. With the 4 pin cable every thing work fine (apparently). Can someone please explain why is there a 8 pin connector and when I'm supposed to use it? I thank u in advanced and i'm sorry for my bad English.

access to more power
That is actually not correct. The current drawn by the processor will be the same in each case. The only thing that happens if the number of pins are doubled is that each pin has to "carry" only half the current. You thereby minimize the chances of overheating/melting the pins or the connector. In that sense, an 8-Pin +12V connection is "safer" than a 4 Pin connection (especially when overclocking an already power-hungry quad core processor.

Strange! What do your temperatures look like now? Doubling the number of current carrying pins of the +12V Connector should have no effect on the CPU's temperatures. It is hard to find an explanation for that kind of behaviour. We are looking at current distribution here, nothing else.

Starting New Build with 990FXA-GD65

I received my 990FXA-GD65 Motherboard.
Waiting for delivery of the CPU: AMD Phenom II X4 980 Black Edition Deneb.
Memory: AMD Entertainment Edition 4GB 240-Pin DDR3 SDRAM DDR3 1333.
Heatsink: COOLER MASTER Hyper 212 Plus.
Question 1. On the 990FXA-GD65 motherboard there is a 4/8pin power connector (JPWR2). My power supply has both 4 & 8. which should i use?
Question 2: The board has an ATX 6-pin Power Connector (PWRCONN1) for the Graphics Card. My GeForce 8800GT card has a 6pin connector attached to it. Should i plug the power supply connector into the mainboard, graphic card, or both?
Thanks for any and all suggestions.
This is a build in progress and i plan on upgrading the graphic card and a few other things.

990FXA-GD65 Vs. 990FXA-GD80

Hello to every-one
I'm hoping someone can tell the difference between the "990FXA-GD65" and the "990FXA-GD80" in regards to performance and durability.
I've seen some people say that the GD65's Northbridge gets hot and that the GD80's does not, Would a hot Northbridge be a problem ?
I may do some light OC'ing.
Basically i would like to know which one would be better
What i will be doing: Game Programing, Gaming, Some rendering and Video conversion.
I'm getting the FX-8120 BTW.
Many thanks.

Advantages:
Dr Mos:In order to provide customers stable and high quality products, starting from P45 series mainboards, MSI is leading the industry to introduce the world's most advanced power supply component, DrMOS (Driver-MOSFET), which integrates Driver IC, Top MOSFET and Bottom MOSFET into one chip. Except for its outstanding performance in power saving, DrMOS possesses switch frequency which is 400% faster than traditional MOSFET and has great improvement in stabilizing power supply and voltage control. Even under heavy loading and overclocking conditions, DrMOS can still provide the most stable and efficient power supply and quality.

Sideport Memory(Useful you buy a vga that support hybrid SLI or use onboard vga): is used by ati tech. as dedicated buffer memory for integrated
graphics,located on the motherboard.It is usually higher clocked ddr2 or ddr3 memory
which is faster than usual system memory providing better performance for integrated graphics.
Motherboards claim for an increased >10% performance by using sideport memory.
3 way sli
APS:Active Phase Switching, APS, technology is an intelligent design that helps to save energy on MSI’s mainboards. The underlying idea is to switch off the power supply as soon as no electricity is needed, and when the system needs more resources again, APS will automatically adjust electricity supply accordingly. APS will automatically detect your processor’s loading at any given time and save energy accordingly. This is only possible by means of a very advanced power controlling technology. Other than software-based solutions, APS technology stands out from MSI's own research. The specially developed IC chip can operate automatically depending on the demands of the power supply, which is to reduce the total power usage.
Generally speaking with MSI boards, the first part of the model indicates the chipset ie 990fxa or z77 and the last set the tier. ie gd 65 / gd 80
Generally the higher the number at the end the higher end the motherboard.

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.

MSI 990FXA-GD65 + AMD FX-6300 + 16GB 1866MHz RAM Won't Boot

Hello,
Today I received parts for my new gaming system (sans water cooler, using the stock heatsink+fan until then), however I'm experiencing problems with the setup. The specs are as follows:
- MSI 990FXA-GD65
- AMD FX-6300 CPU
- GSKILL 16GB (2x8GB) 1866MHz DDR3 RAM
- Kingston SSDNow V300 120GB SSD
- 2x MSI GeForce GTX 660 Ti
- EVGA NEX750B1 PSU
- BitFenix Comrade case
Upon powering on (after assembly), the Phase Indicator only has the first two LEDs lit up (Phase 2 Power Mode, according to the manual). No output is displayed on screen. I've tried removing and re-inserting the CPU and removing one of the graphics cards, to no avail.
I would appreciate any help/advise that could be offered, that I might get this system up and running!
Kind Regards

Try to run this system out of the case on non conductive area (e.g. plain cardboard) with 1 stick of RAM only, 1 GPU (try without any graphics cards too), single HDD/SSD, PSU of course, CPU+cooler and monitor+keyboard and mouse. When booting spam Delete and it should take you to the BIOS where you have to change timings of RAM suggested in the post about GSkill memory.
If possible, borrow different brand of RAM to test your PC with.
Make sure that if you're running single GPU, that video cable is connected to the card. If no GPU, then to the motherboard.

Smoking MacBook Pro Power connector

Hello, I am working on a 13" MacBook Pro for a coworker. She said one day she plugged in the power cable and smoke started rolling from the laptop near the power connector. She quickly unplugged the power cord from the computer and because it was 1 week out of warranty it got put in the cabinet and sat for a couple months.
Yesterday I disassembled the computer and the power connector board has some slight discoloring and there does appear to be a damaged component on it (it is small, looks kind of like a SMD Voltage regulator, but I'm not sure).
My question is this, Has anyone had this problem before and successfully fixed it? Is it just the power connector board or could there have been another failure on the mainboard that caused the connector board to fail, and subsequently cause a replacement to fail if I were to get one (I loked over the mainboard and it appears OK)? Could the power adapter have failed and caused this problem ie over-voltage (the cord and brick appear to be in perfect condition)?
Thanks
-Brad

Normally when we get problems like these in we change both the power adapter and the power connector board

Limited vcore 990FXA-GD65

I have a 990FXA-GD65 and from what I can tell there is a revision 1.0, 2.0, and 3.0. What is the best, most accurate way of finding out the revision of the board? Also, do any of the beta bioses allow more voltage adjustment? The vcore can only be set to 1.45v in the bios, it can go higher in AMD Overdrive. I'd like to not use overdrive anymore but the board doesnt allow enough Vcore adjustment for me to do so.

Its been a BIOS restriction for a long time, and it was introduced when the FX8000 series were launched.
These CPUs start spiking to over 200Watt TDP when overclcoking. The board was designed before these CPUs were launched and thus the VRMs are not safe at those power requirement levels. To protect the VRMs from burning up, the restriction was added.

990fxa-gd65

hi i have a msi 990fxa-gd65 whit fx4130 cpu and i wonder why the cpu temp is inkorekt in bios ? can somone tell mi why ?

When you are in your bios at startup, not ClickBiosII, the temp is likely correct but:
Your CPU will be running at max clocks and not running any powersaving feature like Cool and Quiet. Therefore the temp will be somewhat higher. On mine it wil run anywhere from 38C to 48C depending on if it was running prior or not. After windows login, where the power stages are run like C&Q, It will operate like normal and for mne those temps are as low 27C and only ever really get to 45C under some moderate load. All these tamps are socket temps. It is no big deal.

MSI Military Class II 990FXA-GD65 - No Signal

Hello. I'm an amateur builder and this is my third project. I've spent many hours trying to figure this one out with no luck, so here I am.
All the components are new, save for a stick of RAM. Everything seems to have power. I've only had it boot into BIOS once. As soon as I moved the mouse I lost signal to the monitor. I have not been able to reproduce this. I have cleared CMOS, reseated everything, tried a different monitor and video card and took it down to one weak stick of ram and one HDD. I've also tried using a VGA cable to no avail.The only thing I haven't tried is powering up the Motherboard outside the case. I haven't tried it because I'm under the impression that the motherboard had to be grounded to the case to work properly and safely, but I have seen it suggested on this forum in other similar threads.
Any words of wisdom would be greatly appreciated.

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.

Z68a-GD80 (G3) which power connectors?

The board comes with an 8-pin power socket, with a 4 pin blanking plate on it. There is also a 6-pin socket which I think should only be for multiple GPUs.
My Coolermaster modular PSU has one 8-pin and one 4-pin power cable in the same bundle as the 24-pin cable.
I will be installing one of your 6970 Lightning graphics cards and an i2500k CPU.
So...
I assume I remove the blanking plate and use the 8-pin power cable, but do I need to use the 6-pin with just this GPU? If so, is the 4-pin cable any use, or do I need to use all 6-pins and hence a molex to 6-pin?
thanks
Blonkster

Remove the plastic cover & use your PSU's 8-pin EPS/ATX power connector. The 4-pin is of no use. The mainboard 6-pin connector is for a PSU PCI-E power connector, or a dual Molex adapter to PCI-E 6-pin. If you have a PCI-E PSU cable left over after the connections to the VGA, may as well power the mainboards PCI-E 6-pin too.
Thanks, I don't have a spare 6-pin cable, so I assume I don't need to obtain one for the single graphics card - it has two 8-pin connectors of its own!

Please help with this issue.

You have already been advised using more graphics cards than what is supported is not going to work. That is a user to user support answer that was provided. This is not MSI but a user to user forum of MSI products. MSI is not involved here, and the opinions & statements here are not connected to them in any official manner. Your question has been answered. This thread should now probably be locked.

It is sad MSI cannot support their customers in professional way no matter what they are using their equipment for. It is my private matter and counted on support. Thanks anyway

990FXA GD65 CPU voltage reading

Hi, I Have an MSI 990FXA GD65 with an AMD FX 6100 cpu.
I have been struggling with this board for a while trying to match the voltage I set in the bios to the readings I am getting from CPU-Z and HWMonitor.
at default with CPU voltage set to auto in the bios cpu-Z and HWMonitor show 1.32v at idle and about 1.30v under load with P95, if I set the cpu voltage to 1.4 in bios they show about 1.48 at idle and 1.44 under load.
What puzzles me is that my CPU needs 1.4v in bios to run at 4.2 ghz, this seems to match what a lot of other people are getting with this CPU but if I am to trust CPU-Z's readings then I am needing 1.44v so should I be trusting what I set in the Bios or should I go with CPU-Z and face that I need a lot of volts to run stable and 4.2ghz is as far as I can go.
I also seem to have very low temperatures for running such high voltages, if it's really at 1.48v then surely it should be getting hotter than 46 degrees running P95 even with a corsair H80. Temps were even lower with a thor's hammer in push/pull on there.
For some reason I cannot run MSI ControlCentre in windows 8.1 so I have no idea what that will tell me.
So just joined up here to see if anybody else has the same issue and can give me some advice.
Thanks,

I have the sunbeam twister 120, and it's AMAZING! The fans on it rotate in different directions making the airflow VERY quiet even at 3k RPM. It's a dual fan push pull with 3 DirectCU Healpipes, and an amazingly smooth base. I purchased mine for just under 30 bucks from Newegg (discontinued on their site) and it allows me to push my AMD Athlon ii X4 640 (3.0Ghz) to 3.8 with a 1v change, and still keeps it around stock temps. @ 3.5Ghz (what I run @ stable due to motherboard limitations) I hit a max of 40c core temp and an idle of anywhere between 16c-20c.
Stock temps were about 19-21c idle, and 38-40 under load.
Stock cooler was almost 20c more idle, and under load, so this is DEFINITELY a badass cooler.
It also comes with a fairly decent size tube of TX-4 Tuniq paste which is apparently one of the best in the game, so I went ahead, and used some of that on my HIS HD 6850, and I'll be damned, the paste alone dropped my temps enough to get a world record breaking overclock on stock air cooling. The heatsink also comes with a "RheoSmart" rheostat controller that also plugs into the four, or three pin cpu fan connector, to allow you to switch between manual, or motherboard controller speeds. (Which is pretty awesome IMHO) I absolutely LOVE this thing, and am 150% confident it'll be able ot cool my 8350 efficiently when I get it (if I don't end up waiting on the Steamroller cpu line.)
This is what you're looking for. According to several testers across the internet, this is right on par with a V6-V8 cooler...and over 30 bucks cheaper.

This is the validation for my CPU using the paste that comes in the box with the Twister 120 - btw, that's on the standard stock HS...nothing special at ALL.
