You need to list everything used but in general you need a decent power supplyI have the ASRock b450m-hdv motherboard
What CPU are you trying to power? Many Ryzen APU's and CPU's don't really need the power delivery of an 8 pin and will get along just fine with a 4 pin connector.I have the ASRock b450m-hdv motherboard
I'd have no worries running a 5600G on a 4 pin connector. Now, as to the PSU...I'd have to say 450W, especially a Bronze unit, is quite substandard in modern systems. If not running a discrete GPU it will probably be OK but if ever upgrading to one be sure to factor in the cost of a new PSU along with it. I'll leave others to critique brand and model...if it's needed.I have a Asus tuf gaming 450W bronze psu and it doesn't have replaceable cords. Also I have an amd 5 5600G if that changes anything
