Not ruined at all. The newer M12-II evo have had some slight changes, even going full modular. My 7yr old M12-II is Semi-Modular and not an Evo. It also has 0 issues with my Minuteman Pro ups, which doesn't work at all for my Evga G2 for battery backup. Any group regulated works with any ups, but some DC-DC psus are quite picky and particular and I don't have that kind of cash for a pure sinewave ups.
