Kitchen wall cabinets on triple plasterboard wall (circa 60mm)

Hi,

I appear to have a triple plasterboard wall in my kitchen, two 15mm and a thick middle centre. Doing some measurements the walls thickness is about 60-65mm (drilled through by accident. I have found one stud, which is next to where I plan on placing a new 2 gang socket. So there must be some in the wall, but i am not sure on its load bearing ability.

I already have two 1000 units and a boiler, but was hoping to put 3450mm worth of cupboards, two dec plates and cornice. This would box...
