My friend wants to get a r5 5600x and rtx 3070, and I told him that this unit, the Corsair CXM 650w semi-modular 80+ bronze would be a good choice to power the system, but he's thinking that he'll need more wattage to OC these parts, but I still personally think that this unit can handle the OCs. Should he get a better PSU, or would this one work?
