This is reaching the limit of my knowledge with computers
I have not opened the case of my computer and I do not want to try to because i don't want to mess anything up. Best buy assisted my dad and told him what to do. (Which makes it pretty sure that the connectors were fit for the graphics card).
The Brand of the Power supply is Thermal take and the model is TR2-600NL2NC.
I hope this is still helpful
edit: The connectors WERE
fit for the card.
