Aorus 1080 TI power requirements

[Hytham_1]

Hi , I bought two Aorus GTX 1080 TI VGAs , each VGA was shipped with a single cable which is "6+2 to two 6-ports" connectors .
while VGA have two 6+2 ports .
PS is Raidmax 1200W-Gold certified "Have six 6+2 connections originating from 3 cables" , Manufacture advise to power VGA that's more than 225w with 2 separate cables ..
So my questions is :
1- Since VGA came with single cable , should the other 6+2 port on VGA be left blank ?
2- As PSU cables have 6+2 already , i don't have to use the "6+2 to two 6-ports" cable that came with the VGA , right ?
3- How to operate the 2 VGA with two 6+2 connections each , and maintain PS manufacture advice to use two connections from separate cables for each VGA" ==> PSU have 3 cables with 6 connections

The cables that are included in the GPU are for the case that your PSU does not have the appropriate cables. Since yours have all the appropriate cables then you should connect those and leave the included in the box.

ALL the plugs should be connected with the power cables otherwise the GPU will not perform fully or even not function at all.

The manual says that you have 6 x 6+2 from 3 cables. That means that you will plug 1 cable with 2x 6+2 in the first GPU and 1 cable with the other 2x6+2 in your other GPU. You will be left with a 3rd cable having 2x 6+2 not connected.

Well , the problem is that although PSU is GOLD certified and SLI ready , but there's a recommendation on the PSU cover NOT to use two 6+2 connections from a single cable in case your GPU power consumption is more that 225W

I am sorry, I missread 225 to 275 and since the 1080ti uses around that, then I thought you were good to go.

I don't think there is a safe way (as suggested in the manual by the manufacturer) to connect both GPUs properly.
It's better if you change the PSU with another one that has the appropriate power, quality and connections.
If you can afford a 1080ti (you can afford 2!!!) then you can afford a new PSU.

This is my New PSU actually , it's 1200W Gold rated , that's the best model i found locally .. Any pages that shows Aorus 1080 Ti power consumption on difference modes ?

You don't need 1200W. You can even go for 850W and you will be fine if the PSU is good. You should return it if you can and buy another one that is more capable of handling 2x 1080 ti. Something like this:
http://www.corsair.com/en-gb/rmx-series-rm1000x-1000-watt-80-plus-gold-certified-fully-modular-psu-eu

I couldn't find power consumptions for different modes but I saw that while peaked it consumes around 282W.

That info is for the Aorus Extreme edition as you already mentioned. The OP has the simple version of Aorus

Hytham_1 To be perfectly honest, Raidmax PSUs have a horrible reputation for quality, despite your model having a gold efficiency rating. Did you purchase your power supply in the US? If other, please specify the country and two websites that you're comfortable ordering PC components from. Please answer my questions when you have a free moment. Also, what did you pay for the Raidmax? We can offer suggestions on your purchasing a high quality model. When you're dealing with the power requirements of two 1080 Ti's, you cannot afford to fool around with a subpar PSU.

Currently at UAE , leaving soon so i've no time to return it , for 1200W PSU , almost all websites are out of stock , i originally bought thermaltake toughpower , seller sent a different model "guess RX2" that's bronze rated so i returned it ,
I basically tend to use the 2 VGA for mining , so i needed 1200W that would supply 3 VGA "1080 ti" ... I tend to keep all GPUs on the slowest mode for stability/safety ..

Understood. No worries. I hope that you make lots of money from your mining. Good luck.

I had the following 2 ideas to maintain PSU recommendations , please evaluate if that can work out ,
The PSU have 4 modular 6 pin ports ,
The first idea is to use the cable below :
https://www.amazon.com/JacobsParts-Express-6-pin-Video-Power/dp/B00OSLGBIC
so that each two 6 pin ports on PSU go to a "two 6-pin to one 8-pin" converter ..
The second idea is to use peripheral cables came with PSU "6pin to molex" , use the following converter https://www.amazon.ca/StarTech-com-LP4PCIEX8ADP-6-Inch-Express-Adapter/dp/B006PHXLRG/ref=sr_1_1?s=electronics&ie=UTF8&qid=1500239766&sr=1-1&keywords=molex+to+8+pin
in the second idea , can i use a single cable from PSU "6 pin to 2 molex" to convert to the 8-pin ? or i have to take 2 molex from two separate cables ??

Thanks ,,
Pls refer to my last reply , Below is the back of the raidmax PSU
http://www.pureoverclock.com/wp-content/uploads/images/review/power_supplies/raidmax_rx1200ae/raidmax_rx1200ae_10.jpg
what i think of , is to use only one 8 pin connector from the 3 cables in the PSU .
So i need one more 8 pin connection ,,
i can buy three (6 pin to 6 pin) connectors in the image below , connect 2 of them to a "dual 6pin to 8pin cable" , use the remaining 6 pin connector to power my old 1060 GPU .

That will leave me with 1 6pin port on PSU which can be used for HDD .
Likewise i can avoid using molex converters , have single 6pin/8pin connection per cable ..
