Hello, My 1070 FTW has 2 8pin power connectors. I would like to know if I can connect only 1 of them without damaging the card. I'm ok if it doesn't get the full power/performance.

The card won’t boot without two connectors plugged in.
If you use a dual 8 pin cable, it will cause lower performance than having two separate cables connected.

I doubt the pc would let you power up without both power connections.

Time for new psu with proper 2-4 8pin pci-e connections. 600-750watt model would work fine.

+1  won't boot There is a reason there are Two 8-pin connectors EDIT: (Hope this makes it CLEAR) The EVGA GPUs at this time -- [to the Best of My knowledge] -- are Not designed to "WORK" if All power plugs are not Connected They are Not Designed to feed all parts of the circuits from one port. [The second 8-pin (in this case) is NOT for OC the GPU, but basic circuit feeds dedicated to that set of 8-pin]

I'm not a kid :) For a card which can be under/over volted through software, it just as easily could've have capped at 150w if only one pci-e connector is present.

Have you read the posts, especially #6? No, it will not run without the required power plugs plugged in. You will get an error message telling you to turn off your computer and to plug in the required power adapters. And you people wonder why I made the snarky comment above.

Refer to reply number 1. The answer was no before, and stays no now. Use a dual 8 pin connector, as I suggested the first time. It is a single cable with two 8 pin plugs on the gpu side.

Why do people have to be so rude when answering a question. For the record it is possible (even though I would not recommend it) to power some graphics cards without the power connectors attached but you need a very heavy duty overclocking motherboard drawing a lot of power to do it.

Because I for one am sick and tired of sugar coating things, especially when it comes to things that are common sense. And if you thought I was being rude, well you'll have your eyes opened up once you reach the real world and start asking these exact same questions in a corporate environment. You won't be getting my type of responses, you'll be getting security to empty your desk and escort you off the premises. If you need the truth sugar coated and covered in pillows, I'm sorry you were raised in such a shallow environment. The real world doesn't work that way, especially when it comes to repeating the same ignorant question, when it's already been answered.

I have worked in a very brutal environment for the last 40 years and I can really dish it out if I want to as well. I am grateful to my old boss who was an absolute animal to work for (he would make Donald Trump look very limp wristed) as he showed the very worst and also the very best in people. One thing my old boss showed me is it was not necessary it be rude when it was not needed, on the other hand if you are going to dish it out make sure they know you mean it. You get far more done by being nice than you do by being an "£$%

My pc gifted friend would always tell me to “look at the connections on the part” before i bought it and to answer all my silly questions. I now look at all connections and know what to expect when a part shows up so that i am prepared to support it.

please don't brick your card by trying to hook it up any other way than the directions say.. I am sure your upset that you have a double 8 pin card and single 8 pin wire from your PSU. Buy a new modular PSU and enjoy the awesome card you have.

You think that is rude? You can’t undervolt something that won’t boot. Why would you get upset that you are being treated like an adult? It’s simple, you had your answer, and it doesn’t change. You are required to have both plugs connected, as stated in reply number 1. To undervolt, you have to boot into windows. Without both plugs installed, you can not. See the vicious cycle of repeating steps here? It is extremely frustrating to repeat the exact same thing over and over. Especially when people are clearly misguiding you and saying it can be power off of the pci lane, which is a lie. https://m.aliexpress.com/...1Dt41ZtZhoCEiQQAvD_BwEThis will allow you to use 1 8 pin to make to act as a dual. It’s $2 usd.

They sometimes come with a dual 6 pin to single 8 pin. That doesn’t change the requirement of needing two 8 pins if they are required, it just means you have a single 8 pin and stil need another.
