Hi The Asus WS Z390 Pro mobo I am building has one extra Eatx 12 volt 8 pin header and one extra EATX 12 volt 6 pin header. Asus tech told me I only need to connect to EATX_1 and the other two headers are for bigger power supplies. He also gave me the impression that I could use them to use power to the gpu's if needed..??? I was supposed to get a email pushing me to level two tech but I never got the email... I have a new EVGA Supernova 650 G5 and it doesn't have enough rails to supply 4 gpu's...and two extra motherboard headers (1 8 pin cpu out 2 VGA out ), I think...lol. Each EVGA 2060 gpu has one 8 pin connector and the ROG Strix 2060 oc has 2 connectors one 6 pin and one 8 pin...you are supposed to use both. I have extra psu rails, from other installs, and I am curious if I am supposed to use the extra motherboard psu headers for to supply power to the gpu's, because the psu doesn't have enough outs. So recapping My power supplies have two 8 pin out puts for PCI use. Rails have eight or six pin outlets for the gpu...I think I have one eight pin with dual outlets of eight pins each, which came with the EVGA 650. My problem is I only have two eight pin outlets from the psu to supply possibly 5 (4X8 pin and 1X6 Pin) gpu connections. At the moment I have 2 gpu's that I could install (1 evga 2060 and 1 ROG 2060) If I wanted to combine all of my current gpu's in one machine I would have.. 3xEVGA 2060(one 8 pin each) and 1 ROG Strix 2060( one 6 pin and one 8 pin) HELP!!!!....lol

You want to power a system with 4 GPUs with 1 650watt PSU? Not so sure that will work so well. I did a power calculation with EVGA's power meter 1000w Seems to me I would want to go bigger than that with 4 GPUs and CPU and MB Normally the 2nd ATX 12v is for high overclocks where the CPU needs and can get more 12v power. They are not there to feed a GPU. What kind of cable would you use? I don't think so. And you want to power a GPU from the mohterboard using the 2nd 12v CPU power plug? Never heard of such a thing.

Why not get a PSU to dedicate to those GPUs? And use the 650W to power what it can. Just make sure to power on GPU PSU first and turn it off last, so the system POSTs properly.

' bill1024 You want to power a system with 4 GPUs with 1 650watt PSU?
Nooo, Nooo I want to install a couple of cards that I currently have EVGA 2060 XC and ROG 2060 OC(which might be going back if it doesn't play nice) The 650 should be more than enough. After that I will upgrade the PSU but when I was looking at the specs on the EVGA 1000 series I didn't see any extra power outlets on it.... Eventually I will be trying to max out the boards capabilities with more gpu's bill1024 Not so sure that will work so well. I did a power calculation with EVGA's power meter 1000w Seems to me I would want to go bigger than that with 4 GPUs and CPU and MB Normally the 2nd ATX 12v is for high overclocks where the CPU needs and can get more 12v power. They are not there to feed a GPU. What kind of cable would you use? I don't think so. And you want to power a GPU from the mohterboard using the 2nd 12v CPU power plug? Never heard of such a thing.
So now you understand where I am at, I too did a calculation using EVGA Power Metter but I didn't see any more power outlets on the 1000w models. (Just saw the second cpu out..on 1000w) I hadn't heard of such a thing as two extra Eatx 12 volt power inputs on the motherboard or two power inputs on one GPU card (the Rog Strix has a 6 pin and 8 pin to be both used) I am on a voyage of discovery...lol Just need some help making it work with what I have and growing from there guys and gals..

Seems beyond my cases dimensions and my capabilities..lol Building it in a Coolermaster Haf EVO workbench case...don't want to hack it though.. Good suggestion , food for thought whiskywarrior89

Asus usually makes a fairly good manual - should answer what those power points are for - my last WS was a Z97 & its still running as a Folding rig The additional Power to the MB for PCIe = extra power for better stability when using 2 or more GPU on that MB Most (all current ?) EVGA PSU are Single Rail In the past - you the user - had to divide your load across many independent power rails - inside of the PSU --> by how you connected your hardware to those outside power ports on the PSU. Current standard is a Single rail - so users do not have to manually balance the load some nice basic explanations are found: lifewire

For 2 gpus you shouldn't need to plug an extra 6 pin cable into the board. You just need the ones attached to the Gpus. The extra 8pin for cou power isn't needed if you aren't on liquid nitrogen cooling. Only extreme overclocking will use the extra juice.

Hi Cool GTX Obviously I am in over my head at the moment..lol I read the manual and looked online...just matter of fact info on the EATX 12 volt headers. This one is here and that one is there etc...I called Asus customer support and was supposed to get a level 2 upgrade email...never got it. Just finished rummaging around in the EVGA PSU product line and started top down with a look at the 1600w and it has enough power outs. The 1000w had the same as the 650w(Sorry can't remember why I thought that) I have a OCZ 700w, I was using, and it has the same number of outputs, as the Evga 650W. I am under a time crunch at the moment and want to test the ROG 2060 OC in a new working computer so I have a need to make this work with what I have currently. (I have a time limit on returning the ROG cards, I have one I was trying to use and they sent me a replacement. I must return one in the 30 day window or possibly both depending on results, that window is closing. I also have Muscle control issues and things can take me too long to accomplish.) I have a EVGA 550w PSU running a prime Z270 with 2 EVGA 2060's purring along and I don't want to pull it apart and jinx it...lol It has lots of fans running(7 case and cpu + 4 gpu fans in 2 gpu's) and absolutely no power issues Want to use the WS Z390 Pro to test out the ROG card. I will be installing the cpu today, with a Coolermaster 212 EVO, this may take awhile for me. I will also be looking at trying to figure out something that works with the psu rails. Don't want to use two separate psu because I am concerned the power might not be cycled or balanced properly. I will check back before I power it up. Thx

When in a rush, I just place / replace one of the GPU in a working PC I get your need to decide if your keeping a new part The PSU is the Single most important part of your build, yet usually the last thing people put in their budget process Without stable power the rest of your PC will never be stable Multi GPU Rigs & new builds are a different story ... as you see planning is the first step PSU - what to buy ? 1) Make sure the PSU has enough power connections for the Build you have in mind 2) I go by the rule of thumb that 100% of the calculated load does not exceed 80% of the PSU output for Rigs that will run 24/7 My EVGA 1200W & EVGA 1600W have work very well on my Folding Rigs 24/7 .... plenty of power with enough cables to get the job done GL on your adventure

Thanks I tried the ROG Strix 2060 in the Z270 and I got the same error and I tried the working EVGA 2060 in the earlier B450-F I sent back. It scared me and I was relieved when the EVGA 2060 worked again in the Z270. Part of the problems I may have been experiencing is not using both 6 pin and 8 pin on the Strix 2060. I have discovered you are supposed to use both. From my perspective...PSU's have limited outlets on their case and they are marked clearly for usage. The connectors are dummy proofed to help the challenged configure it correctly. Since the outlets are limited... do I need to use wiring harnesses with multiple connections to supply power to multiple headers...for gpu and motherboard? ie...my EVGA 550 came with a rail or harness with two eight pin outlets leaving a second outlet on the psu...never saw that before.. Obviously I will be shopping for a larger psu down the road but... Do I need to get or use a couple of harness's like that to supply the two connectors on the 1 ROG gpu and possibly 1 EVGA 2060? ...

Nvidia cards will detect if both power leads are detected. So you have to use converters if you don't have enough proper connectors. Try to make sure if possible to use different cables per converter to be safe. Certainly this is not a preferred long term solution as molex really isn't designed with that use case in mind.
To troubleshoot an defective GPU requires running it solo with no overclocking of either GPU or CPU. I have never had any problem with EVGA or MSI tech support with regards to RMAing a card. You just have to do the grunt work of isolating the GPU.

Converters...? ahh Molex ..Adapters...I think I get you. Your talking about using the other power outs on the PSU and converting the ends. Since this is bypassing the dummy proofing ....LOL Where should I rummage around to figure out the best converters for use?and which power outs to use? Last thing I want is create a 10Tid error...lol My current collection of GPU's are 3 EVGA 2060's with each having one 8 pin and 1 ROG Strix 2060 having 2 power inputs...1X6 and 1X8 I just found out I have to connect both, on the ROG(I thought it was either or...oops), so I wish to retest the one Amazon has sent a replacement for. That way I can send back it unopened, for resale. ipkha To troubleshoot an defective GPU requires running it solo with no overclocking of either GPU or CPU.

The PSU you have now should have 4 GPU wires, that will be enough for 2 GPUs you said you are going to use. You do not have to connect the GPU extra power plug on the board for what you are doing. Are you over thinking this? If when you add more GPUs you will need a bigger PSU, get one with enough leads at that time, no?

If I read the first post correctly, each vga header from the psu has a single end 6/8pin not a dual 6 and 8 pin. So he only has 2 gpu cords for 3 gpu inlets or 4 if you count the motherboard.

bill1024 you are both wrong and right at the same time...lol Which is good. 2 vga outlets BUT the wire rails will service both gpu cards. 1 has a combo end with 6/8 pins and 8 pins and the other has one 8 pin. One eight pin for cpu etc.. So you are close enough in my book Thanks ipkha If I read the first post correctly, each vga header from the psu has a single end 6/8pin not a dual 6 and 8 pin.

I answered above ipkha, I was mistaken about the need for adapters I was panicking unnecessarily... My bad. Thanks to both of you, for talkin me off the ledge...lol Joe
