I own the EVGA SuperNOVA 1600w PSU and I am at a loss as to which power cable I can use to connect to this connector on my Asus Sage X299 motherboard. This is a 6-pin EATX12 connector. A good picture is: It is labelled EATX12V3 in this schematic: Any advice is warmly appreciated!

You'll need to use a 6-pin pci-e cable.

I use the word triangle here loosely to denote a pin that isn't square.
With the clip oriented up: the motherboard is accepting "pins" in EATX12V3 with the Square, Square, Triangle Triangle, Triangle, Square Question: Is it acceptable to connect a PCI-E which is pins: Square, Triangle, Triangle Triangle, Triangle, Square
The primary difference being the middle "pin" in the top row is a triangle on the PCI-E cable and not a Square. Accordingly, I know it will fit, because a triangle with go into a square (but not vice versa).

I have that same layout Asus x299 Sage and Evga Supernova 1600 T2 watt power supply. That connector on that motherboard is for the power of the pci express x16 slots and also remember that the board has two PLX switches to run pci-express slots on all 7 will run at x8 and if you use 1,3,5,7 will run at x16. You need to connect one cable from the VGA connector on the power supply to that of the motherboard a 6 pin connector.

Thanks for the responses everyone. Pozzallo, to be specific, do to you do the following: Use the 6-pin part of the 6+2-pin VGA cable? Specifically, you plug this 6-pin into the EATX12V3 on the mobo and you connect the other end of the cable to one of the VGA outputs on the EVGA T2 1600? bcavnaugh, I have already connected successfully the A, B and C connectors as you have outlined from the manual (which I have read cover to cover, but find useless). I understand I should not plug in the 6-pin cable if I don't plug in the others. However, as per my sentences above, I am curious as to which PSU cable will safely accommodate the 6-pin connector on the Asus X299 motherboard. To reiterate, will the standard PCIe VGA 6+2 pin suffice (using only the 6-pin part) ?

Yes I think that is that is the only way because of the cables from the power supply does not have a 6 pin by its self it is with a 6+2 pin and the other end to the VGA connector on the power supply. So the 6+2 pin part of the cable is not connected to anything. Glad to help

Thanks everyone. @bcavnaugh I am currently plugged in with A, B and C. I am keen to try plugging in D as well (the 6-pin) since I am having problems seeing all four of my GPUs in bios and get a B2 post error 4 out of 5 times. Once I saw two GPUs, but that didn't last long (and only happened once in dozens of reboots). It "feels" like a power issue, so I'm really just asking whether I can use the 6 part of the 6+2-pin VGA cable in the connector labelled D on the motherboard diagram. The question arises because of the slight keying difference. Sajin has answered positively... so I'll give it a go.

@Pozzallo, do you plug into EATX12V2 as well as EATX12V1 ? I was hoping that by plugging into EATX12V3 I would resolve my post issues where b2 error code often shows up and also only 1 GPU appears in Bios/Windows. I tried removing the 8-pin into EATX12V2, but didn't help.

Yes jtromans have to plug into EATX12V2 and EATXV1 that is for your cpu. The cable marked CPU with 8 pin or 4+4 pin on the power supply to the motherboard you have to do both cables as there are only 2 cables in the in the cable kit supplied by the power supply and there are only two connectors on the power supply marked CPU 8 pin. Also EATXPWR has to be connected to the cable 1600T2/2000 MB 24 pin to the MB connector on the power supply to the motherboard connector EATXPWR

Did you go with 2 Separate PCIe Power Cables to Each Graphics Card or only One Cable to each? I would recommend 2 Separate PCIe Power Cables anytime a Graphics Card has two Connectors.

You do not need to connect this unless using multiple high power graphics cards.

@pozzallo: makes sense to me; this is exactly how I have connected mine. @bcavnaugh: Yes I am now using ALL 9 VGA power outputs from the PSU, two for each of the GPUs (to make up the 2x 8-pin required for each card) and one for the motherboard EATX12v3 6-pin connector. @TheMadDutchDude: Appreciate you are trying to help. My specification is as follows: - Asus WS X299 SAGE w/ BIOS 0905 (90SW0070-M0EAY0)
- i9 9900X (BX80673I99900X)
- 4x Palit GeForce RTX™ 2080 Ti GamingPro
- GSkill 128GB DDR4 2800MHz (F4-2800C15Q2-128GRKD)
- Samsung 970 EVO 1 TB
- Windows 10 Pro
- EVGA SuperNOVA 1600 T2 80+ TITANIUM

I once used a 4-Pin Molex X2 to 1 6-Pin VGA Connector for the Motherboard to free my PSU PCIe Cable. Easy to for a 6-Pin but not for a 8-In as it uses 2 6-Pin to create on 8-Pin. Both uses to come with your Graphics Card but now I only see the 2 6-Pin to create the one 8-Pin.

Well I've connected all the cables just fine, using the ones I had. It seems as though my 6+2-pin VGA cable is sufficient for the EATX12V3 6-pin mobo connector. However, it hasn't help me with the underlying issue, which I described above as b2 error 4 out of 5 boots, plus only 1 GPU showing in Windows (or Bios)... sometimes I see 2, but that has only happened twice out of 30 reboots or more.

Have you Pulled the Battery from the MB to Or maybe needs a Bios Update. On EVGA MB some have Dip Switches that allow us to turn off PCIe Slots. B2 and seeing that it refers to "Legacy Option ROM Initialization" >>>> Disable CSM in your Bios maybe. But I would also Disable any feature in the Bios that that you are Not Going to be using, like the Raid Controller. Check the Pins in all your connectors Both Side, one or more may have been pushed out or not all the way in.

Issue: Intermittent (90% of the time) B2 post error (with Boot led on motherboard) and only 1 of 4 GPUs showing in Bios and Window 10. - GPUs were tested individually one at a time in PCIe Slot 1 while on Air Cooling and all worked. Never tested in multi-GPU config until now.
- I can sometimes rarely get to Windows, without a pattern on why. Regardless, only ever see 1 GPU (not 4).
- Seems to always boot to Windows after CMOS button reset.
- Turning off "fast boot" in Bios seems to help with getting into Windows, but unsure.
- Only one of four GPUs showing up in Bios or Windows 10. Specifically, first slot GPU is showing in BIOS and Windows. GPUs in other slots do not appear in Bios or Windows.
- Windows 10 installed with UEFI and Secure Boot on. Have tried booting without Secure Boot. No difference.
- Have flashed Bios with latest version 0905.
- Have flashed visible GPU bios to latest Palit version (90.02.17.00.35) which seemed up-to-date anyway. Can't flash other GPUs since they don't register in Windows or even in Bios
- Have updated to latest GeForce Windows 10 drivers, not that I expect this to make a difference.
- Have reinstalled Windows 10 without impact.
- Have tested supplying power to just one GPU at a time, in each slot respectively. Only when power is supplied to top slot GPU will Windows boot at all. Power supplied to GPUs in any other slot gives b2 error with white "VGA" led on Motherboard (as opposed to "Boot" led on motherboard as described above).

Are all the Cards Locked in the PCIe Slots? Let's hope that it is not being caused by Bent CPU Socket Pins.

Not seeing this info in this Thread but do you have a 44 Lane CPU? The Windows Install of the NVIDIA Graphics Drivers are missing all the Features of the Driver Mostly OpenCL "Have updated to latest GeForce Windows 10 drivers, not that I expect this to make a difference." But if you do not see the Graphics Cards in the Bios then Windows will not see them as well. Test a Graphics Card in Each PCIe Slot........ Bent CPU Socket Pins??????

Yes the i9 9900X (BX80673I99900X) has 44 lanes. I've already tested each GPU in slot 1, and they all worked.

Would the setting 'Above 4G Encoding' be relevant here? Has anyone else successfully booted 4x 2080 Ti GPUs ?

Yes sorry I miss-typed - I meant Decoding. I don't know what constitutes a Grid card, but I tried enabling it and it didn't help my issue so I have disabled it again.

It Must be Disabled for GTX and RTX Graphics Cards. The RTX Graphics Cards are not Tesla Cards.
