    Default please what this power supply and how watt

    Welcome
    I always browse the site but this is the first reference in it
    I bought a computer from a person. I found this power supply. There is nothing written on it and I do not know how much energy.

    sorry my lang

    Feels like a "just ok" 350-450w power supply ... the three fan thing makes me think of PC Power and Cooling power supplies but i guess in the past there were multiple manufacturers using two fans.

    Big capacitors on input which is good, but it's probably fake value because they seem kinda small for 1200uF, small bridge rectifier probably rated for 4-6A so that would make it good for around 4-500w, the heatsinks look decent...
    Fan doesn't tell me anything, not familiar with who used those fans in the past.. Any writings on the circuit boards, codes, numbers, logos, any hint of manufacturer?

    The text on the ICs on the heatsink near the top (secondary side) where those big coils with some red paint on the cream/yellow paper can give you a hint about the maximum power available on various voltages.
    For example if it says MBR2045, it could mean it's a diode rated for maximum 20A and 45v (here's an example datasheet: https://www.diodes.com/assets/Datasheets/ds23016.pdf ), so one of your voltages (3.3v, 5v, 12v) may be good for up to 20A

    You can google the text on those parts and see what that part actually is.

    The number of fans could be a hint that it's a somewhat inefficient design (old) which is pushed to its maximum of what it could do and the addition of fans is to keep everything within reasonable temperature at the maximum power it was advertised.

    The three fans are fake. You can see they don't even match. The one on top has a baffle, which means it was made to be the only fan in a PSU, not one of three.. The caps are too small for what they say they're rated for. This is something someone slapped together as a joke.

    I bought it with i7 3770 and a 1060 3g Thank you very much. I will try to search the components to see the origin.

    Don't bother.

    Throw it away and buy a PSU that isn't a Frankenstein.

    i dont know.but its working great..i have antec neo power 500 watt i feel this power work better.i mean Unknown
    I searched some pieces and found it works very efficiently 98%
    the power supply included 2*8 pin pci e and 2*6 pin pci e thats mean it can install 4 video card.right now i need to know its how watt.

    That PSU is nowhere near 98% efficient. That PSU is an old Topower that someone Frankensteined together and recapped with some fake bulk caps (an actual 200V, 1200uF capacitor is 35mm x 40mm). More like 70% efficient.

    And how do you mean that this PSU is "working better" than your Antec?

    Are you trolling us?

    A 98% efficient supply would not need any fans, let alone 3

    Urgh, that looks awful.

    There is 0905 on the Transformer, so 9th Week 2005?? That thing is almost 15 Years old! Must not be used with modern components!
    That alone is reason enough to NOT use it.

    As for the Efficiency:
    PSU at the time were usually at 70% - if they were good. But Topower was not, they were around 65% in some cases.
    Really not a good unit...
