    Who manufactured your PSU

    Niffy article on Toms hardware about the origins of different PSUs

    They talk about UL numbers which is given by some kind of testing company and points to
    who made the thing, which you dan enter here.

    Do these UL numbers appear on the ones sold in the UK though?

    Re: Who manufactured your PSU

    Well my Coolermaster PSU has a UL number on the side of it, so I guess so. Although looking at an FSP and a Bestec PSU they don't, im guessing this is because they are OEMs.
    Main - Intel Core i5 2300 @ 3.5GHz, 8GB DDR3 1333Mhz RAM, Asus P8P67 Pro, Coolermaster iGreen 600w, GTX 480, Antec One Case

    Also it only needs a UL number to be sold in the US, sometimes psu's are made for a specific market (or the labels on the side can be) so it has no need of UL testing and cert.

    Also a big issue is that many "brands" have gone to the next step and got there own UL number, so the UL goes back to the brand not the manufacture.
    They (brands) can do this by having a 3rd company make new casings and they then just transplant the internals to the new casing.
    By doing this the brand has taken part in the physical manufacturing of the product and so can be listed on the UL number.
    In these cases the only way to know is to open it up

    Which is why this is also a handy link
