So I'm getting ready to do a PC build and need a good DC-DC regulator. The M2 seems to do what I want (except maybe support sleep vs. hibernation).

But I'm a bit put off by all the problems people seem to be having. For most people, is it working as expected? This really needs to be as "bulletproof" as the car ignition and/or PC itself. It can really make or break the whole build.

Are there alternatives or is this the only game in town right now?
