I'm about to install a new 4070 SUPER graphics card in my PC, but I just noticed that I only have a 6+2 cable and a 6 cable available. Ideally, I need two 6+2 PCIe cables for this card. Can I use what I have, or do I absolutely need to buy new cables or a different PSU? I currently have a 650W power supply.

You can't mix cables for your PSU; you have to use the ones that came with it. Typically, your PSU should have two 6+2 PCIe connectors: one is likely hardwired, and the other is a modular cable. Just check around in the box for your PSU; you might find it there!
You really need two 6+2 pin cables for the 4070 SUPER to work properly. Most 650W power supplies come with at least two PCIe cables or one daisy-chained version. What’s the brand of your PSU?

I actually found it in the box, thanks a ton!
