Does the amount of wattage matter for psu cables?

I found this cable set for the EVGA superNOVA g2, but it says g2 1600.

Does it mean only 1600 watt g2s can use these cables?

No, it does not matter. The difference between lets say a 750W G2 and 1600W G2 is the amount of wattage it offers and how many cables it has in total.

Not any PSU - that's a quick way to fry your parts. These ones are only compatible with G2/P2/T2, of any wattage.

The modular connectors on the PSUs aren't the same, manufacturers are free to design them however they want. So even if you could fit a cable from a different brand into your PSU, it will have completely different pinout and voltage on the wires.

For example, a slot for a PCIe cable on a Corsair PSU may have 8 pins, where the top four provide +12V and the bottom ones are ground. While an EVGA PSU may also have an 8pin slot for a cable, but they made it so the top four pins provide ground and the bottom ones are +12V. Even if you have a cable that happens to fit both holes, it isn't compatible just because it has the same shape.

That is how you end up with some toasty parts.
