Yaz or Yazoo is a great band. Vince Clarke was one of the original members of Depeche Mode.
Here's a list of a few electronic bands/artists I really like in addition to the ones above. Not all 80's mind you.
Jean Michel Jarre
Skinny Puppy
Kraftwerk
Coil
The Human League (they became ultra poppy)
Suicide
Men Without Hats
Peter Schilling
Alphaville
Exploring their discography is part of the fun so I won't tell you which one's to look for.
