Is it Safe to Purchase a New Modular PCIe Cable?

I would advise against it unless you get a replacement directly from the PSU manufacturer. Mixing and matching cables can be a fire risk and might damage your hardware.

You can definitely find replacements, but remember that they're specifically keyed for your PSU make and model. I've had good luck buying from Amazon and third-party sellers. Just make sure to double-check the specifications before purchasing!

It's important to note that not all PCIe cables are universal. Some manufacturers make specific replacements, so you need to ensure compatibility with your PSU. If you're not careful, you might end up with a cable that could lead to issues.
