Hey everyone! So I'm pretty new to building PCs and I have a couple of questions about my power supply and some compatibility issues. I originally bought a modular PSU but ended up losing all the cables (yeah, I know - not my proudest moment). I then got a different PSU, which is non-modular, hoping that I'd avoid losing cables this time. But now I'm stuck because the PCIe cables from the new PSU don't seem to fit my GPU (a GeForce RTX 4070) properly. The GPU needs a specific connector that my current PSU doesn't provide. I'm wondering if the new PSU is incompatible, about the wattage ratings, and if it would be better to just buy the right cables for my original PSU instead. Here are my specific questions:
1. Is my new PSU incompatible with my graphics card? It doesn't seem to fit at all.
2. Is 650W enough power for my setup considering the estimated wattage is 530W?
3. Should I return the modular PSU and just buy the cables I need? Are the cables universal, or what should I search for in this case? Any help you can provide would be appreciated! Thanks!

Your GPU needs a 12VHPWR connector, which typically comes with an adapter. If you lost that, you might find it in the box your GPU came in. If not, you can grab one online. Just make sure you get the right adapter!
Oh, I didn't even think to check in the GPU box. I’ll look there first. Thanks a lot!
