It's the famous review where the OCP FAILED or wasn't working?
There is no OCP. That's how they turned the M12D into a single-rail unit. They removed the OCP that divides the single +12V source into two separate rails. However, since they weren't too bright, they didn't bother implementing any OCP on that single rail, which is why the PSU exploded. Twice. It's a design flaw, albeit one that you are EXTREMELY unlikely to encounter.

No. They did a good thing in performing that overload test. It's important to know that there is in fact no OCP, even though the average person will never have to worry about it.

No. It's still a very good PSU, and unless you'll be overloading it by 100W (in which case it would be silly to get an 850W PSU in the first place), you have nothing to worry about.

No. The M12D has OCP as I explained above.
