Thanks exper. Going to do some tweaking today so I can say I did my due diligence before reaching out to the PGH folks. Did a manual add up of the power specs in a spreadsheet as well rather than just going by the specs here on MG.
3 of the modules on the bottom rail have jumpers to offset some of the power to the +5 so going to try that since I wasn't currently using any +5 on the bottom... and double check all my connections while I am at it. Then see what happens. Thanks again.
