I have a gigabyte A320M-S2H motherboard with a 8 pin CPU power connector and my current power supply only has a 4 pin so I am wondering if my ryzen 5 1600x cpu wil have enough power?
What PSU do you have?
If your PSU only has a 4pin, it's extremely dated at this point. You can theoretically only populate the leftmost 4pins of an 8pin header and (in a lot of cases) have things just 'work', but when your PSU does not have the appropriate connectors for your hardware, that's a good sign you need a new PSU.
I have a thermaltake litepower 450 watt psu
While the litepower units are not great, it does have a 4+4pin EPS connector:
