19.5V 6.15A 120W power supply

Gents, I just ordered 2 SCA kits. I have a spare 3 pin 19.5V 6.15V 120W power supply from Dell so I did not order the Meanwell 24v 5A.. I will be running a single ended stereo then balance monoblock at 8ohms. I read from SCA web site that the power supply is 19V for 8ohms.. Can I use my spare Dell power supply with the latest Rev kit? Answers or comments appreciated. Thank you
