I bought a fully modular gskill 750watt psu for my threadripper build it came with a lot of moles and pcie cables but only one 8pin cpu power cable when my motherboard (MSI Pro Carbon AC) has 2 8pin spots, it turns on runs and works but I was wondering what impacts not having that second cable does. From my experience my RAM runs at a slower speed than supposed to and any overclocking is unstable, it’s seems it doesn’t have enough power to even turbo up to 4ghz. (cooling isn’t an issue because I’m using an AIO cooler and 7 case fans so cool air isn’t an issue) I was wondering what other problems I could be having and where I could possibly buy a compatible 8 pin(comparable with the power supply and motherboard)?
