I have a MSI X470 Gaming Plus MoBo with an 8 pin and 4 pin power connector. The 4 pin is labeled "CPU_PWR2" and nothing on the 8 pin. I built this PC in 2018 and have used an EVGA 550 G3 power supply with only one 4+4 pin "CPU_PWR2" cable plugged in and it has worked fine. I recently ordered an EVGA SuperNova 850 G5 (arriving today) and noticed the cpu cables in the picture (and the one on the 550 G3 which I am currently using) are 4+4 pin connectors. Now forgive me if this sounds stupid, but do I use the 4+4 cable for the 8 pin connector (just put both in side by side) and then another 4 pin cpu cable for the "CPU_PWR2" connector (I realize it's for OC)?
Recently I have been getting random reboots (no BSOD) and I'm not sure if the CPU is getting enough power as it is a Ryzen 5 2600x and is running at a clock speed of 4150 MHz at idle and has capped out at 7374 MHz. I thought maybe my 500 G3 wasn't performing as it should but maybe I just need more power? I have the bios set to default and as far as I know, I have not done any overclocking.
