I'd like to recommend the American soundtrack to Dragon Ball Z.
Now, bear with me. I know you don't like anime, least of all this kind of stuff, but some of this music is really good. When they first brought the show over to the states they felt the need to rescore the whole thing, with the composer they chose being a dude named Bruce Faulconer, whose mustache is only rivaled by his mullet.
The soundtrack has a heavy synth/rock/industrial/metal/techno vibe to it, and it's all MIDI, so some of it sounds really video gamey. Here's a few I picked out that I think you might like based on what I know about your music preferences, as well as some of my personal favorites.

Just about all of the DBZ American Soundtrack has been released on CD over nine volumes. The rights to the music is actually held by the composer, and not the owners of DBZ, or even the localization company that commissioned the music. You can find them on Amazon, or eBay, or wherever by searching his name, Bruce Faulconer.
Every album has also been uploaded to YouTube in their entirety in the form of hour long videos for each, complete with timestamps in the description with names of each song. I'd recommend starting with these and deciding which albums might be worth picking up—that is if you're interested at all. Not every track is amazing. Some are really corny, and others feel kind of phoned in, but the ones that are good really stick out. I just cherry pick the ones I like most.
I hope this was helpful though. Happy Birfmas.
