The white plug is the weird small power one, compared to the new PSU plug
Even the screw holes on the back of the Pc case were out of place for the new PSU.
Blimmin ACER!! what are they playing at?
That's the joy of prebuilt PCs from big manufacturers. That and a ton and a half of bloatware pre installed usually.
You're not wrong!
It's surprising how easy it was to plug the bits together and then just install Win8 with no other rubbish on there.
Now I know how this one has gone together, I need never buy a pre-built PC again
