I am a electronics tech always working on a crazy project

I am electronics technician and I do this as a hobby. I was looking for info on a possible grounding issue I thought I was having. I take 6 dell 180W laptop bricks and combine them together to get a 58V 18Apower source to a dps5020 I recently purchased.
This is a crazy project. I gotten good info from this site on other projects and decided to join.
