FYI going from a GTX 970 to a GTX 1650 is a decrease in performance, not a upgrade.
Some GTX 1650 require a 6-pin connection so you may only need that single cable. There are some models that don't even require a 6-pin, usually the ITX versions.
I've tried running it without the cards and everything runs fine lights on fans on just no connection to the usb ports or display ,Sounds like a power issue more than a gpu issue. I'd remove both cards and run off the igpu and see if you get a display or not. If you don't, you've got even bigger problems...🙁
So does the system operate 100% fine without the cards? Or are there still issues? If there still are issues, it is the motherboard, and unless you know what you are doing, stop and take this to a shop or you're going to kill the whole thing dead if you don't know what you're doing.I've tried running it without the cards and everything runs fine lights on fans on just no connection to the usb ports or display ,
I've also got an asus pbz77 -V motherboard
Ive read on a few forums that other people have had this issue and it was their motherboard or "mobo"
I'm not sure what that is, others have said that it was a burnt out ram stick but ive tried that too
but i'm going to keep trying different things
Yea the system works completely fine without the cards, I did take the motherboard out and cleaned/dusted it and put it back together tried it with the new 1650 and now theres no issues.So does the system operate 100% fine without the cards?
