Hipro HP-d3057f3r computer power supply broken?

I have a Hipro HP-d3057f3r power supply in my computer and I think it's broken but I'd like to know for sure before I buy a replacement.

There is a green LED on the back of the power supply that turns on when i plug the computer into an outlet. But when I push the power button on the computer the LED turns off. The power light turns on and the power supply fan turns on but the other cooling fans don't and the computer shows no signs of trying to boot up. If I let it sit for about an hour it will finally start up. It will work fine for a few days then it will suddenly quit and I have to let it sit for a few days unplugged and repeat the process.

    Theres no problem with the fans they all work fine, i was just providing that as an example because NOTHING except the power supply cooling fan starts when I press the power button to turn the computer on. the laser on the mouse and thelights on the keyboard briefly turn on as if the computer is trying to boot up but then they turn back off. the hard drive never starts spinning and the computer doesnt seem to make any attempt to boot up. but if i let it sit for an hour or 2 it will eventually boot up and run like normal

I have the same problem. I found this:

  • Replace the side panel, plug in the power cord, and examine the light on the back of the power supply:
  • If the LED is on solid and is not flashing, the power supply is probably good and the problem is most likely caused by a defective component (processor, memory, PCI card) or a defective motherboard. Have the computer serviced, or remove the components and replace them, one at a time, to find and replace the defective component.

    Check the cooling fan on top of the CPU heatsink. OK you have to remove the side of the PC but it is a common problem, easily checked.

    Cover off blow hard on fan and it should turn freely if not replace. It is the ONLY fan that has to work for the PC to start. That does NOT mean that it is the only fan you need or should have.

    Hipro hp d3057f3r up to how much can my pc have ram?


    The very best thing to do is to go to crucial.com. They will take a look at your motherboard, and tell you how much more you can add, if any, and will sell you RAM which is compatible with what you already have.

    I am looking for a schematic for a Dell Optiplex GX280 power supply. The supply is model HP-U2106F3.


    I just replaced my GX280 power supply (mini-tower) with the following 400W for $30.

    The only place I can think you will find an actual schematic for the PSU is from the manufacturer.

    The LED on my HIPRO D3057F3R power supply is illuminated but the fan does not run. Does this mean that the power supply is bad?


    Yes, it does.
    More than likely Electrolytic Capacitors, have gone bad in the power supply.

    Electrolytic Capacitors are used in the Input, and Output stage of the HiPro power supply, as Filters.

    In the Input stage they filter the incoming AC voltage.
    In the Output stage they filter the rectified AC.

    (AC is rectified into DC. The capacitors are filtering DC at this point.
    AC = Alternating Current
    DC = Direct Current
    A flashlight battery is an example of stored DC)

    The HiPro power supply you have produces three main voltages. Three voltage Rails.
    A.3.3 Volts
    B.5 Volts
    C.12 Volts

    When Electrolytic Capacitors go bad, or are failing, there is a weak voltage rail.

    HiPro power supply's are cheaply mad.
    1.The wiring is too small. (The gauge of the wire is below standards)

    2.The Electrolytic Capacitors are of low quality.

    3.The rectifier bridge has cheap diodes, and too small of a heatsink.

    I could go on, and on.

    When you have a power supply with a weak voltage rail, there is not enough power for the Processor.

    1.ALL the lights use less than 1 Watt.
    2.EACH fan uses 2 to 3 Watts.
    3.A typical Processor can use 55 to 125 Watts!
    [Depends on what processor it is.

    This is why lights - light, and sometimes fan's will spin, but the computer won't run.
    Not enough power for the Processor.

    Solution?
    Replace the power supply.

    Viewing this link,

    http://www.pcmarketusa.com/product_view.aspx?product_ID=18498

    ,you can see the HiPro D3057FR3 power supply has just the usual ATX shape, and size.
    The ATX 'Form Factor' power supply, is used in approximately 90 percent of computer towers.

    [Form Factor usually denotes towards a motherboard. An ATX form factor motherboard is 9.6 inches by 12 inches. Form Factor means the size, and shape.
    The Form Factor designation, has been used towards certain hardware parts in a computer, as well as the computer case, but this is erroneously used. It does make it easier to identify with, though. That's why I used it here]

    Point I'm getting to?
    1.See if you have another Known, GOOD, ATX power supply to use for a test. Test my statements above before you go out, and buy another power supply.

    Do you have another computer that has a good power supply, but may have other issues, that you can borrow the power supply out of, to use for a test?

    Another thing. This manufacturer overstates the actual rated Wattage. The actual wattage is more like 70 percent of what is stated.
    They state 300 Watts - Maximum, but in reality it is more like 210 Watts.

    It is for this reason, and the reason that components used in the above power supply are cheap, that I would recommend buying a different power supply, than buying another HiPro.

    (Therefore,.NO, I do not recommend the one in the link above, as a direct replacement)

    What power supply that fits your needs would I recommend, that is a decent quality power supply, and won't break the bank?

    This one,

    http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4675269&CatId=106

    OCZ StealthXStream 400 Watt.
    Why?
    Because it has 80 percent of the true rated wattage.
    320 Watts actual.
    Because it is reliable.
    Because it has all the power cables you need.
    Because it is $28 USD after the rebate.

    I'm sticking my neck out recommending a particular power supply here, as this goes against our TOS, but if you have no background in this area, how are you going to know what to look for?

    I am not recommending the website. But I have used them repeatedly, and always to my satifaction.

    Any questions?

    HAVE A HIPRO PSU PART NO. HP5187-4875


    A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacement from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic

    Won't turn on - PS light on but no PS fan


    Surely sounds like the power supply is in need or replacement, or fuse replacement at absolute least.  the fuse that you will be in search of will be located inside of the power supply unit.  Use caution when working inside the power supply.  If you don't see a fuse in the power supply, OR you come to find that the fuse is not damagaed then you will likely need to replace the power supply.

    When is the Hipro HP-A2007AE power supply cooling fan to be on?


    The fan should run constantly. It needs to be replaced. Otherwise the power supply will shut down when it gets hot. It can usually be replaced, but if the supply is cheap, just go out and get a new one.
