I have a power supply with only a 20 pin motherboard connector, but my motherboard has a 24 pin. Can I just use it as is? Do I need to get a new one? Or will this adapter work? https://www.amazon.com/StarTech-com-6-Inch-Motherboard-Adapter-ATX2024MF/dp/B0002GRTZQ/ref=pd_sim_147_3?_encoding=UTF8&psc=1&refRID=MVQPCVZTBPTGRKSWFXZV&dpID=41J88wNEOzL&preST=_SY300_QL70_&dpSrc=detail
