I'm planning on buying an RX 470 to upgrade my current pc and so far so good according to PCPartpicker: https://pcpartpicker.com/list/2k4gpb

There is still one thing I would like to know before buying though. Basically, two years ago I wanted to upgrade this same PC to an R9 290 but for some reason the motherboard/pc did not detect the graphics card.. The graphics card also worked fine according to the manufacturer so it definitely was something on my end. What I'm thinking is that it either could have been the Nvidia drivers or me not plugging the card to the PSU properly. I ended up selling the 290 because I'm an idiot and ran out of patience.

So what I would like to know is what kind of cables would I need to connect the graphics card to the PSU? Would I need to remove all Nvidia drivers and install AMD ones before hand or is this not necessary? Does anyone maybe know why I had issues before?

I'm sorry if I sound like a complete idiot, but I'm really scared that I end up spending about 220EUR and it not working again. I currently have a 750Ti that is working fine.

Also the thread I posted from two years ago: http://www.tomshardware.co.uk/forum/id-2399376/dvi-power-saving-mode-d2500n-monitor.html

As you say that is your current part list. You should have everything you need to connect the Rx 470. The R9 290 should have worked as well. Perhaps there is something wrong with one of the PCIe 6+2 pin power leads. You can test them with a digital multimeter or PSU tester with PCIe power connector support.

Leaving the nVidia drivers installed shouldn't be much of an issue. Although people usually remove them. I suppose leaving them might slow things down a little. As the nVidia control panel and GeForce Experience will be running in the background. Otherwise a computer isn't going to try and use drivers it has no hardware for. Unless you manually update the driver and select the wrong driver.

But shouldn't the graphics still be detected even without the PSU? Sure, it would need extra power to play games and all but I'm pretty sure the system should still detect it as the fans were spinning I believe.

Could this have been a solution to the problem I was having?:h ere are the steps I tried to fix the issue on my computer.

1. Turn off the computer and unplug
2. Remove Graphic card
3. Plug the monitor to your video output
4. Turn on the computer
5. Click on start and type msconfig
6. Select the Boot tab and click on the box that says Safe boot with minimal selected.
7. Apply then click ok.
8. DO NOT RESTART.
9. Shut Down computer and unplug
10. Install Graphic card
11. Turn on the computer (should boot into safe mode)
12. Go into Device Manager
13. Expand Display Adapter
14. Disable the Intel(R) HD Graphics 4000 driver. (DO NOT UNINSTALL)
15. Click the start button and type msconfig
16. Unclick Safe boot
17. Restart

The computer will restart normally and will no longer get the black screen. See if that works for you. I didn't mess with any setting in the bios. I am assuming that having two graphic driver install don't like to play well with each other :)

-RAM Patriot Viper 16GB
-Video Card Asus Nvidia GeForce GTX 660 DirectCU OC 2GB
-Processor Core i5 3570k
