I had this problem a few weeks ago when fitting a kitchen in a new
house. It included 4 shelves going round 2 plasterboard walls.

These walls were the flimsiest walls I have come across since doing
this for a job.
I knew they were plasterboard walls, so bought a selection of fittings
from Screwfix in case of any problems. Of 4 or 5 types tried, only 1
fixing actually worked well - very similar to this one he

Anchor-5-x-72mm-16-32mm-Pack-of-10

I use the 5 x 52mm ones all the time. Agreed very strong fixing. The
setting tool is well worth £6.50 if you are using them regularly

I got them from the local hardware store - the longest available,
probably 80mm long, maybe 100mm. They do not have a minimum wall
thickness, which I think some of the Screwfix ones do.
Once fitted, they were rock solid when tightened - fit them first
without shelf brackets, make sure they are tight, then just unscrew,
and refit - can be used many times, as they are a set screw, not a
wood type screw.

I could not recommend any for thin plasterboard walls. I tried most of
them, and all failed miserably.
Also, ITYF that the spacing between the stud fixings is nowhere near
the spacing you want to secure the cupboard, so at least one end will
be secured into the cavity.
