SSD power supply question.

Hello Folks,
Is anyone using an adjustable power supply on an SSD system ? I have seen cables available for this set up.
If so,how much voltage/amps can you run through the system before there are issues?
The standard system is 15V and 4A I believe, and I run two standard wall mount type SSD power supplies as per the book instruction.
When a car is deslotted there is an increase in performance in the other cars when running 6 cars at a time.
Has anyone played with this?
Electricity is not my thing.
If I could run an aftermarket power supply with 6 or 7 amps available I believe this would fix my problem.
Am I on the right path?
Is this OK without frying my power base?
Help please.
