    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.

      Testing ATX PSUs under load - Does loading the ATX 24 pin also load EPS & PCIE?
      by AJ847.63e
      Hi Folks,

      Just wanted to clear up a misunderstanding of mine (or what I expect is one). Isn't the 12V rail from the 24 pin, EPS and PCIE separated? IE if I put a power resistor on the ATX 12V pin that is not going to load, thus tell me if the EPS or PCIE rails are fine?

      I was recently watching ArIs from Hardware Busters video on how to properly test ATX PSUs without using 5 figure Croma substations.

      The PCB adapter he used breaks out the 12, 5 and 3.3V pins from the 24 pin and gives you banana plugs to connect to. That is a bit useless is it not? Aren't...
