Help finding correct power cable for GTX 1060 SC in Mac Pro 5, 1

I recently purchased an old 2012 Mac Pro 5, 1.

I have upgrade several parts including installing an Nvidia GTX 1060 SC 3GB.

I am a video editor by profession, so I quickly installed Premiere Pro. After a few hours the computer shut off suddenly, then rebooted on its own.

This has happened ~15 times now. Generally when I have multiple video applications (e.g. After Effects, Media Encoder) open.

My first thought was drivers, due to the system report that noted the graphics card was the issue.

But I’m now predicting the graphics card is drawing too much power and causing the reboot.

Looking at this guide, it notes that I need to use both mini PCIe power ports to power the card. However my GTX 1060 SC 3GB has a 6 Pin connector, not an 8.

I can only find dual mini 6 pin to single 8 pin cables.

Can someone help me find the correct cable for this?

Or am I crazy, and putting more power to the card would fry the system or just not be the issue?

Other Note: I installed these other things in the Mac Pro:

  • SSD in a PCIe slot
  • 4 HHDs in the hard drive bays to make a RAID
  • 4 port USB 3.0 hub in a PCIe slot
  • BluRay Drive

NVIDIA Driver Installation Issue (Not able to Install latest version) GTX 1060 Zotac

So, whenever i tried to install NVIDIA driver through software and updates application, I used to get blank screen while booting through normal mode.

latest driver for NVIDIA is 418 so far, but in the update menu it just shows up driver version 390.

My questions:

How do i get rid of blank screen while booting?.

Is there any other reliable source to install NVIDIA driver with latest updates?.

Is that okay to run GPU without native it`s driver configuration?.

Second monitor is gone after reboot in GTX 1060 Nvidia

I have MSI GTX 1060 graphic cart on my Ryzan 2700x pc.

GTX1060 has HDMI and DVI output.

One of my monitors (LG BRAND) has HDMI input and it is connected to GTX1060 via HDMI cable as primary and works well with no problem.

I have an old monitor (SAMSUNG SYNCMASTER) that has only RGB in input port. so I purchased a DVI TO RGB convertor (UGREEN brand) in order to connect the second monitor to GTX1060 graphic cart.

here is convertor image…

every thing work well and I have extended dual monitor. But when I reboot the PC, the second monitor (DVI) is not detected !!

And when I unplug DVI from graphic card and plug it again, then second monitor detects and it works with no problem.

I check NVIDIA control panel, Bios and etc but I couldn’t find what is the reason? why DVI port is not working after system boot !!?

I tested another scenario, I removed HDMI cable from graphic and did reboot the system and pc booted via monitor connected to dvi correctly.

it seems when both hdmi and dvi monitors are connected to graphic card, only hdmi monitor detected and dvi is not.

it is very hard to unplug and plug cables physically each time after rebooting and also it may damages for ports for a long time.

Please help me. sorry for my poor English.

Display artifacts on fresh install with GTX 1060

Just installed 18.04.1 LTS, updated, upgraded, added in the Nvidia repo, and using the 396 driver. With all of this done, I’m getting random black line artifacts coming across the screen if I’m on a bright screen on my main monitor.

I’m using a GTX 1060, with two monitors, one connected via DVI, the other connected via HDMI. The DVI monitor is fine, it’s also an older monitor, but haven’t had any artifacts or anything on it. It only happens on my main display.

I have Windows installed on the same system (gaming), and the problem isn’t there, so I’m assuming it has something to do with software/firmware. I’m not sure where I should progress at this point. Anyone have any ideas?
