    Identify component Fractal Design fd-psu-in2b-750w

    Hello, I have a Fractal Design fd-psu-in2b-750w PSU.
    There is burned resistor. Unknown value.

    Can you identify it?
    CHIP IS TNY280

    Looks like 2R00 to me. It can’t be a large value resistor with that large diode in front of it.

      I tried 2Ohm resistor and PSU started, and all voltages are OK.

        Easy fix!

          Sure, but why datasheet specifies 1K? 1K burns in flames like on other PSU with same chip.

            I think they limit the current and at the same time it acts as a fuse.
