The PSU passes all ATX v3.1 transient response tests, but the 12V and 3.3V rails drop low.

  1. Hi, Aris! I scrolled down Enermax’s website, and came up with Enermax Revolution III. It is said to be ATX 3.1, and i’m pretty sure it’s a replacement for Revolution DF judging from its price

    Would you be consider to review this unit? Thanks
