There are also some power consuming cards on the computer, which need external small 4P power supply (that is, floppy drive power interface) to work more stably.
Or when the power cord is not long enough, it can be used to transfer.

If the computer power supply only one small 4P power interface, which is not enough, so you can try this conversion line.

Large 4pin to small 4pin power cord, small 4pin head (floppy drive interface) is a standard component with an anti fooling buckle in the middle.
After inserting it into the seat, there is a buckle in the middle that hooks onto the seat, making it less likely to fall off, when inserting and unplugging the cable, be careful not to use force to pull it out. If force is used to pull out the cable end or the plastic of the seat, we can first pull the cable up a bit, that is, first detach the buckle from the seat, and then pull it out
