    What's that PCB between the secondary Heatsink and the small (3,3V) Coil??
    Primary cap seems reasonable enough -> 270µF/400V for 450W seems OK.

    Secondary Caps are Teapo SC -> could have been worse (Like ChengX, JunFu/AsiaX in an 80plus Gold PSU. Even if it's only the small 50V ones)...

    14pin Protection IC, so OCP on all rails possible (If implemented correctly)...
    And UVP on +12V also.


    Nothing unexpected...

    Is that Bridge Rectifier even heatsinked? Since i don't know what kind is it.

    I know 450 watts is not much but i wonder what kind of components they used on 12V,and 3.3V,5V side of the PSU.

    I wish I had the ability to wonder these types of things. But then everything is just some A38S928X820 chip or something and I have no idea what that even means and what the pros/cons are.

    No. It's not. That's what I said in my earlier post. It's a cost down of the Corsair new VS. No heatsink on the bridge rectifier and smaller transformer.

    I read the post of course jonny, but i asked that because since its a step "down" what kind of bridge rectifier is it a GBU404.

    What Bridge Rec. does the Corsair VS Series use GBU404, or GBU606?

    You mean GBU406?

    I need to double check. The old VS used GBU406. I'm in Taiwan and don't have the BV and VS in front of me and don't have the change list on my laptop.

    But I know they were the same and had a tendency to overheat at full load.. that is, if it was allowed to get that hot before the transformer saturated and shut down the PSU. Pick your poison.

    Thanks for clearing that up jonny, i got confused and thought it was a GBU404, still i would have prefered a beefier transformer and at least a non heatsinked GBU806.

    An 806 is quite overkill, though. 600V, 8A.

    That is true but i prefer overkill, especially safety wise.

    Wtf who am i kidding(safety pfft..) i'm still using an Ultra LSP 600 Watt PSU with Anodia caps...on an old PC i have.
