Upgrading ramps to supply > 5A to motors

I’m using 5 DRV8825 Drivers on my ramps 1.4 to drive 5 Nema 17 motors.
My motors are capable of drawing up to 1.5A and my drivers are set to accommodate
Assuming I had all 5 steppers running at full power, this is a total draw of 7.5A

Is there a way to upgrade my ramps board to allow for this?
I’m thinking of upgrading the 5A pollyfuse & maybe one of the mosfets.

Any suggestions?
