VHS Dreams, FM-84
Check out Power Glove, specifically their EP 2043: Volume 1. It's a bit different to your regular synthwave, it's darker and a bit more influenced by techno.
I'm a big fan of Starcadian.
Scandroid
Gunship, Perturbator, Capenter Brut, Gost, Makeup and Vanity
Powercyan (RIP), Alex & Toyko Rose, FOOL, Extra Terra, Lazerpunk, Scandroid, Isidor, NightStop, Arcade High.
As far as artists who primarily make synthwave:
Dance With The Dead, FM-84, Gunship, Lazerhawk, and Magic Sword
I'm also a big fan of Erang (he mostly makes Dungeon Synth music, but he's got a couple of synthwave albums, namely Anti Future and Songs of Scars
Zone85, gunship, Waveshaper
Pilotpriest, Lazerhawk, Kavinsky is great, too
If you like darksynth, Perturbator. His Dangerous Days album slaps.
Mr.Kitty’s Ephemeral album is one of my favorite electronic albums of all time.
Perturbator, VHS Glitch, and on the more chiptune/metal side but still synth: Master Boot Record.
