Question about Okia 420w UL Approved ATX Computer Power supply (OKIA420ATX) Power Supply

1 Answer

Friends custom-build PC has no power

Working on a fiends custom-build PC that doesn't have any power. No fans,no lights,no noise...nothing.

I tried the Okia 420W PSU in another PC and works fine. Bypassed the on/off switch still no power. Is the Asrock k7vm3 mobo the problem or something I'm missing here?

Thanks in advance...

    Bingo! Took mobo out of case and it came to life. Put it back in case and started adding hardware one by one then testing to see if still had power and problem occurred once front USBs were added. Thanks again...

Seems reasonable. Take the motherboard out of the case,  first to see if it will work outside of the case. Sometimes boards short to the ground due to a screw or other metal getting between them and the case. Try to run it with as little hardware hooked up as possible. You don't even need a hard drive to post the BIOS.

Power Supply Dry Run Problem


You need to have the case's power switch plugged into the jumper pin header of the motherboard. Plug in the PSU into the 120 volt mains, enable the PSU via the switch (the one you turned on in the video) and then press the power switch on the computer CASE.
That should do it!

PC won't start: Jedi solution


Many times when a customer's PC will not start, though it seems like power is getting to the components (fans are running, etc), I have simply turned off all power, including the power supply off switch if it is so equipped, disconnected all cables to all peripherals and surge protectors and waited a few minutes. Then, I connect everything back up and nine times out of ten she fires right back up and all is well. An electronics technician friend of mine suggested that static charges can build up and somehow keep the pc from starting, and disconnecting everything releases the charge and it works again. I'm not sure if that is exactly why, but I can tell you that it works!

When I put my PSU on the ON position, it makes no noise, but when I turn it off, it makes a hissing noise and does the same if I unplug it. It was bought two weeks ago and made noise when I first used it,...


if its only 2 weeks old should and its brand new be under warranty

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

hope this helps and good luck building your first computer

Gateway 500s power box when hitting test button powers both fans, but no power to hardrive, dvd, or monitor. I have replaced power supply, motherboard, and harddrive, I have nothing, but green power button...


Does the fan on the power supply run? As you say the power on switch lights up and so does the motherboard, means that the power supply is working. Monitor gets power from the socket on the power supply. Try plugging it in the wall socket. Try to unplug the main power cord from power supply to the motherboard. The one that has a broad plug at the motherboard end. Replug it and they power on the PC.

Alienware aurora desktop with 525 Watt Power Supply was working fine then all of sudden started making a loud noise like it was going into overdrive or something then emitted a horrible like burning...


The switch mode power supply in the desktop computer has failed. Most likely the capacitors in the power has exploded.
You need to open the desktop computer and remove the old power supply and replace it with a new one. Take the old power supply with you to your friendly computer shop and get a replacement power supply with the same wattage or greater wattage.

My computer is making a buzzing noise the fan is working and friend told me it was probably the power supply


I would first try cleaning the computer and removing as much dust as possible from your computer. Also clean the fans, this could be the reason why your fan is working so hard. Just make sure your computer isn't turned on and not plugged in.

THE FANS WORK BUT NOTHING SHOWS ON THE MONITOR AND ITS QUIETER THAN USUAL


1.Cooling fans work?
2.No Signal shown on monitor?
3.Harddrive doesn't make any noise? (To explain. Harddrive is inactive. Not spinning, and the arms aren't moving back, and forth across the platters)

Suggest it's a bad power supply. A common occurrence.

Why?
1.Owner fails to keep the inside of the computer clean, and the power supply.

Dust/Dirt/Spider Webs/Lint, you name it, builds up inside. This foreign material clogs up cooling components. Specifically the Processor fan, and Heatsink, plus the power supply fan, and heatsink's inside the power supply.

Result?
Processor heats up. Takes more power to run, until eventually it turns off. (Processor's have a thermal limit. Once this thermal limit is exceeded, BIOS turns the processor off)

Power supply heats up. Fan blades and center hub collects Dust/Dirt, as well as heatsink's inside the power supply. Cooling capacity drops tremendously.

Heat = Wasted Energy. The power supply puts out more, and more power to keep up. Eventually components inside the power supply fail. They burn up. (More on this to follow)

2.Cheap power supply. Cheap construction, and cheap materials used. Pre-built computer manufacturers generally use cheaply made power supply's. Saves them money.

A.Gauge of wiring used inside is too small.
B.Electrolytic Capacitors used are of an inferior design, and of cheap quality.
C.Circuit design is below par.
D.Other components used are of low quality.

So how does a bad power supply still light-lights, and spin fans?

Bad power rail.
Personal computer power supply's put out three main voltages.
A.12 Volts
B.5 Volts
C.3.3 Volts

Electrolytic Capacitors used in a power supply are Filters. They filter the incoming AC electricity, and the rectified DC. When one or more capacitors fail, or are failing, a bad power rail results.

1.ALL the lights uses less than 1 Watt.
2.EACH fan uses 2 to 3 Watts.

A typical Processor uses 55 to 125 Watts. Depends on which processor it is.

So you see, you can have enough power to light those lights, spin fans, and even spin the harddrive motor, but not enough to turn the processor on. (Or if it does turn on, not enough to keep it running)

You can easily prove it's the power supply at fault, if you have a known, good, power supply to use for a test.
Another 300 Watt unit that has the same power cables. (Should be stated as has at LEAST the same power cables. It can have more power cables, and these just won't be used)

No processor running you get no signal to the monitor. Computer isn't working to give a signal to the monitor.

Computer is quieter than normal, because you don't hear any harddrive noise. No processor running to access the Operating System on the harddrive. (Or programs and applications)

(Windows XP is an example of an Operating System. O/S)

Just for information, this link gives details of the components inside a harddrive. Gives you more info about the Arms, and Platters I referred to above.
Just thought I would include it. It is not advertising for this website, but is included for reference.

Very soft ticking noise from the power supply fan


There may be some build up on the fan blades that the compressed air could not free. try using a Q-tip to clean anything stuck on the blades.
