can a bad psu make your cpu vcore jump around?

[MiExStacY]

or does it relate to the motherboard also

 

[Soulkeeper]

yes it can
bad motherboard components and regulators can also cause it

if yur other voltage rails are highly stressed then the vcore can bounce around a lot

Yes both that why Quality over Quantity is the rule for PSU and watts while Major Named MoBo's take the cake.
