I have a question, the Computer doesn't start, there is only the power led on on the back of the power supply, can you assist in troubleshooting the issue


Replace your PSU then test all leads that are attached to your hard drive sounds like a faulty lead of some sorts then
try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty because a computer has to have an end to the circuit any fulty leads will lead to no boot up
good luck

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

Hipro HP-d3057f3r computer power supply broken?


I have the same problem. I found this:

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=bph06788&product=12455#bph06788_section_2

  • 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.

    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.
