    2x inductors (L) and a capacitor (C), parts of resonance network. No idea why it's called like that but it basically means that PSU uses a resonant converter design on primary side, improving efficiency and eliminating hard switching (much less transformer whine and ripple to filter out).

    Yeah. When I tried to market it way back then, we called it "frequency conversion" because that made an easier launch pad to explain to people what was different. But then BFG went out of business and people that didn't know the difference took over at other PSU companies so the message got lost.

    Seems there are two variants: zero voltage switching (ZVS) and zero current switching (ZCS)

    The Corsair PSUs that are LLC are CX, TX-M, RM, RMx, RMi, HS, HXi, AX and AXi.

    The only DF ones are VS, CV and CX-M.
    CX-m is like 5 years old now (how time flies), when are we gonna get a refresh? Or has Covid shut down any possibility of a semi-modular LLC bronze platform...

    Who knows. Not on my radar. As long as LLC costs more than double forward, there's no path of upgrade for Corsair.

    When CX was upgrade to LLC, DF was still almost as expensive. Now DF is even cheaper that it was before making it more desirable for low cost products.

    It's going to take a mass movement to LLC to bring the price of LLC down lower. Sort of how the price of using DC to DC for the non-primary rails has made it almost as cheap as group regulation.
