Just got an MSI 915P Neo2 Platinum mootherboard. It has a 24pin PSU connector. In the manual it says:
"You may use the 20-pin ATX power supply as you like. If
you’d like to use the 20-pin ATX power supply, please plug your
power supply along with pin 1 & pin 13"
What are the disadvantages of useing this 20pin PSU on this board?
Should I use a 20 to 24 pin converter, or just leave it be?
