I recently got my hands on an old EVGA 650W G5 power supply from a friend who upgraded to an 850W GT. I've noticed that I have more cables than what came with the 650W G5 according to unboxing videos and Amazon listings. I'm curious if it's safe to mix and match the CPU, VGA, and SATA cables from these two models, especially since I've heard that EVGA allows some cable mixing. But honestly, I'm not sure how to interpret their compatibility charts for PSU cables.

Yeah, I've read that too! Plus, CableMod has confirmed that their E series cables work for both the G5 and GT, so that’s a good sign that they might be compatible.
It’s not worth the risk! The PSU cables have different pin configurations on the PSU end, which can vary even between revisions of the same model. So, it’s best to avoid mixing them to prevent any potential issues.
Actually, you can mix those specific models! According to the EVGA website, the G3 and G5 cables are interchangeable. Just look up the compatibility info. However, keep in mind this doesn't apply to most other brands or models, so be cautious!
