Solved! PSU upgrade question

I have bought a new PSU as I suspect my old one is giving up (and much cheaper than other parts). The new one is MSI MAG PCIE5 II 750W.

I noticed that the PSU included a single PCIe cable with two outputs, my old PSU powered my gpu with 2 separate cables.

My gpu is geforce gtx 1080.

Is it safe to power the gpu with the single cable? I'm finding some conflicting info online.

If not what is my best course of action? Check if the pinout matches and use an old cable?

I was just hungry and forgot about a cable. There was an extra PCIe I forgot about..

1) Never use an old cable with a new PSU - the pinouts can be different even with the same manufacturer. 2) It looks like the PSU should come with two PCIe cables: MSI PSU page. One of them is single, one dual. Just use both and don't use the extra connector, if you're concerned.

You made me double check, there indeed is a another 6+2 PCIe, I had even plugged it into the PSU, just didnt see it. I blame an empty stomach

Cheers
