    Bestec FH-ZD221MGR

    This is one of those SLIM units. The caps all LOOK OK but all the outputs have about 1.2V ripple. (no load). I have the GRN/BLK shorted to run. When in the PC it will not stay turned on. Anyone have familiarity with this one ? It has 2 riser boards. One with FAN control and the other a bunch of Aluminum SMT caps. I compared to another known good ATX (no load) and the ripple is 600mv so that is half the Bestec unit. Is the best thing to put a load on it to be sure ? I've read that the ripple might be less under load. In circuit all the caps show ESR of zero.
