    Default Psu oem question

    Hi , im new here so i hope im not breaking any forum rules...any way guys , a question for you gurus about this psu which i received , it seems to be xilence performance c 700 w. The problem , or rather the question is, who is the oem of this psu , or if in the very least anyone knows if it is at least a halfway decent power supply. I took a few photos , and will atach them. What i could make out was that at least , most of the caps are nichicon or chemicon , but also found some chengx capacitors...

    The OEM is Huizhou Sinhuiyuan Technology, despite the name its a 550w PSU and Im not sure Id trust it to do that for any length of time. Its a really bad unit and Id suggest replacing it ASAP.

    It does have some decent input filtering (could you take more pictures, including the PSU label?)

    Input Filtering
    4 Y caps
    3 X Caps
    2 Coils
    Hmm is that an MOV? hmm looks like an NTC thermistor?

    Main cap is a Nichicon, though i hope its not fake

    The secondary caps are a real grab bags of letdowns

    I see some ChengX and it looks like Chiisi... yeah and the (FULL) bridge rectifier is not even heatsinked.

    I would probably use it on a old system that requires a low load, and not worried if the PSU died.

    Ignore that. The Rating is bogus...

    Here a way better Review:
    https://www.computerbase.de/2015-10/...uper-flower/3/

    ...where the Xilence Performance C didn't fail...
    But Overload Protection is lacking.

    Still electrical Performance, though only 350W, is fine for the price and can compete with the "legendary" Seasonic S12II-Bronze...


    But I'd replace it anyway as it is a group regulated box without good protection.
    That's two big issues in the "nono" box...

    But you could do far worse than Performance C...
    Wich I'd expect to do exactly as the box/label says and not one bit more (and probably also rated for lower ambient temperatures like 25C, max 35C instead of higher like 40C or 50C)...

    Thank you Stefan for your reply , so it seems that , after all , it is not terrible , or to be more precise , it is not a ticking bomb , or something that will straight up explode. I can probably expect this psu to drive a 250-300w pc with ease as it is rated 550 w with peaks up to 700w ( not counting on that really). The system it is powering now is a ryzen 3 1300x and a rtx 2060 that is undervolted so that its power draw doesn't exceed 70-80 watts . The ups shows a max draw of 272 wats so i think it should be okay. Btw if it matters , the ups is an apc , full sine wave , 550w rated , for up to 40 minutes

    Well, its still a pretty low end PSU.
    Not as awful as it could be but due to lack of protection not something I'd trust too much.
