Enermax 1000w + EVGA 680i Mobo compatable?

My 850 and 680i in sig are running sweet na problems.

Yes...I think this connector is optional. I don't think it is even on the striker. And I can verify from my build that on the Abit IN9 you can't even plug it in !! The 2nd card blocks it. If you already have 2 pci-e connectors going into each G80, I can't see how you need this 4pin aux, expecially with a quality psu.

On my last abit board it was optional too, but when you put in 2x7800gtx's the 4pin between the cards was blocked.

Flanno we both have the same Mobo and CPU, my cpu seemeds to be multiplier locked at 10 max is yours the same? I thought these chips were unlocked, or is this a Mobo restriction?

Really sorry it didn't work for you, are you sure you done it like in the HeavyH20 pics. Look at the 2nd to last pic and press on it so that the pic comes up in another window zoomed in. He has cut right in to the molex itself. I think may have even pulled them out to make sure. But I don't recommend you do that , without specialist tools and a lot of skills.

The grounding part won't cause you any damage since most 8800gtx sli certified psu's come with a grounding lead bult in. Another reason why this psu probably didn't get the certification. I think because the galaxy psu has a metal casing it needs to ground itslef when deling with such a whiny power port. Don't worry it can't cause damage.

Yep I've trimmed it right down...haven't yet tried grounding as I've sent a email to enermax support asking them for info.

Do you have the 4P molex plugged into your mobo?

ATM things seem to be running ok...I've O/C'd the CPU to 3.3. Still getting a whinning noise from graphics cards (i think), when I run the ATITool. Hasn't crashed for a while

The QX6700 is multy unlocked well over 14 x so somit`s holding it back m8.

No 4 pin molex needed unless you run SLI.

Must be the Abit IN9 bios then, another thread just popped up on same subject at top of board here, and also another report over at xtremesystems here.

Just to confirm what the guys are saying, on the IN9 with 8800GTX SLI you CANNOT plug in the additional molex on the mobo. U cant get the bottom GTX to sit properly in the PCI-E slot if u do. I too have an Enermax Galaxy 1kw. Will do plenty of testing shortly, so I'll let u know about stability.
I cant believe they would have made such a bad mistake on the placement of this connector if it was 100% required for 8800GTX SLI.

Yes, but the point of this thread is whether the Enermax works properly with the PWR3 4Pin Molex connection.

If you don't use your machine for SLI its kind of irrelevant, however for people with SLI or want to use SLI its important.

clone · 21 Jan 2007 at 14:09

Yes you use the molex with any psu if you intend to run SLI

Okay guys I have two psu's with me at the moment a Tagan 1100watt and an eneramx galaxy psu. I am waiting on something so all my stuff was packed away, hence why I was not able to give anyone a straight anwser in this. I got out my 680i board and proceeded to test this. I first tried my Tagan, and it came on for a second but then switched everything off as expected .I then tried the Galaxy, it came on and kept going, it didn't switch anything off, which I assumed meant it didn't have the same kind of circuit as a Tagan. So I then try the Auxiliary (PWR3) plug with the Galaxy and just like topic creator I got two short beeps, a red light and power off. It tried all the molex's and all modular ones. The thing doesn't work. I didn't try the cutting technique but I did try the grounding one. that didn't work either. We need help on this or otherwise it's going back and i am gonna get a certified psu (the tagan is damaged so that was going back anyway). Note I didn't have any components in the board I just wanted to do a quick test. But the TC did have all his components in and so did the 2nd guy so I am not gonna assume that my systems is any different if I am already getting beeps and I haven't even plugged any component in yet.

The manual very clearly says it's needed to provide additional power for pci-e cards. You don't need this connector if you are running G80's as the 2 pci-e cables already provide enough voltage. Was the same on the last Abit board I had, couldn't use the 4pin aux connector as one of the cards was blocking it. Don't know why people are fussing.

Baxtor - yeah, the Quad is unlocked but for some reason on this mobo I cannot increase the multiplier !! This IS bad as the quads have an issue going over 300fsb. Has this been addressed yet on the Abit support forums.

Also - can't get memory to post at 900mhz 4,4,4,12,1T. 850+ is best I can do. Will try 5,5,5,15,1T at 900.

<edit> Sorry to go off thread...I was talking about the IN9 </edit>

Actually all the manual says is "The PWR3 connector is an auxiliary power connection for graphics cards. Exclusive power for the graphics card provides better graphics performance."

The reason "I'm fussing"

is that I had issues running the game rainbow six vegas (had assumed it was the game), and got exactly the same issues when I tried the ATITool. (3Dmark06 caused no issues).

Since I can't use the PWR3 slot as my PSU refuses to connect to it, I was asking the question was this to blame, or did I have some other driver/system issue. Also I was asking if other enermax users were getting similar issues.

Flanno · 21 Jan 2007 at 15:32

Sorry mate...I was confused and thought this thread was about the IN9 which does not seem to have issues without this being plugged in (which you can't do with 2 g80's over the connetor being blocked)

No prob

Maybe PWR3 isn't a problem on mine either, the manual is a bit on the vague side.

Can you try something please. Plug your gpu's exactly like how HeavyH20 has (the pic I showed you). He has one modulat and one loom power connector for each gpu. Is that how you done it? If not try it liek that and then plug in the auxillary.

Its fact ive had sli before,the cards need the extra power.

BigRon · 22 Jan 2007 at 08:51

Well when i 1st built mine system,I had mine plugged in,run fine,after a week had a few issues and run it with out and i found an increase in nearly 1000 in 3dmark06. So i would not know either to have it plugged in or not.

I also think the evga maual sucks,Always been an asus man,thought i'd have a change,will be going back to asus in few months.

No they don't! The sli spec very clearly says your cards need a psu that is able to provide 60amps on the 12v rail which is overkill. My Etasis provides 70amps on this rail, and the 12volt rails can muster a peak of 840watts on these rails alone. Enough power to run a small reactor

The molex connector is a legacy device that was designed to support cards which do not have dedicated pci-e connectors but may need extra power for stability. Low to mid end 7 series. If you need it when running G80's on the EVGA then that is a problem with the nvidia reference design or a psu issue. I have never read anywhere that says you need it for sli...all I have ever seen a mobo manufacturer state was that is was required to either provide additional power for pci-e devices or to provide power to pci-e devices which have no dedicated power source.

I've been getting beeps from my Galaxy 850 for a while now, usually during Oblivion, it doesn't crash though and I'm not running SLI (yet), I've been given an RMA number for it but haven't got round to sending it back.

Flanno · 22 Jan 2007 at 18:07

Sounds like an issue on the 12v rail (damaged psu) or possible 1 or more faulty pci-e connectors.

Try this - unplug the pci-e connectors from the card and instead plug in both of the pci to dual molex adaptors that came with your G80. This will mean you will need to use 2 molex connectors from your psu for each card. If you don't get the beeping it means the pci-e cable is damaged. If you do get the beeping, then there is not enough power coming from the 12v rail. Either way your psu needs rma'ing by the sounds of it.
