    Ok.. So it's the secondary heatsink. Interesting how the AC inlet is on that side of the PSU, then the primary side is all the way on the other side of the PSU.

    Erm... That's what most power supplies are like. AC inlet on the right, goes through EMI filter to the primary side on the left.

    Except I don't see any EMI filter XD

    Also, after translating, I found the PSU is rated for 300W but it's peak wattage is 550w.
    Here's what seems to be the same platform, yet wildly different output ratings: http://www.tspk.hk/product/26.html

    I distinctly recall another old PSU with a BIG external heatsink right outside the vent holes. Any help?

    Zalman didn't have it on the outside of the grill, but pushed up against the grill with heatpipes coming off both the Primary and Secondary side to the heatsink.

    Yeah. "Erm" (???), that's true that they most are like that. I guess I've gotten so used to seeing fully modular units with well defined primary and secondary separation, I forgot that. I mean, even this Aerocool Integrator I have sitting here as a paper weight has a good 30mm between the socket and the PCB, there's EMI filtering, then a long as hot and neutral wire running to the other side of the board. Maybe it's just the angle of their photo.

    And yes, it has no filtering because filtering costs money.
