I just took a volt meter to the plug that plugs into my motherboard to test the voltage and I seem to be getting about 5 volts out of two of the twenty pins.This power supply is only about 3 months old.It's a cooler master I bought at compusa.I opened it and didn't see any bad capaciters or anything burnt.

Re: is my power supply bad?
You should have 5V at any pin with a red cable, 3.3V at any pin with an orange cable, 12V at any pin with a yellow cable. All black cables should be 0V.
Is the PSU actually running or is it just plugged in? -
Re: is my power supply bad?
I pluged it in and turned turned the switch in the back of it on.And I used the black wire as a ground.What is the proper way to test it?And what would you use for the ground.
When I plug it into the motherboard it turns on and the fans spin.I forget if the fan spins when its not pluged into the motherboard and I cant test it now because I'm out of state working and I'll be back Friday.Comment

Re: is my power supply bad?
When it's not connected to the motherboard you can fool it into starting up by shorting the green wire (PS_ON) to any of the black wires using a bent paperclip or something - this should be perfectly safe to do but be careful and don't kill yourself or damage anything :p
This won't stress the PSU at all though so you may be better off connecting it to the motherboard and testing it while running
As for ground any of the black wires should work fineComment

Well, if is faulty in anyway... you just voided your warranty by opening itOriginally posted by brbpab94

Re: is my power supply bad?
I'm expecting it to post after I changed the three bad caps I found on the motherboard and it didn't seem to make a difference.D you think I should change the rest of the same size caps on the motherboard?
When I start the computer I looked in the back where the led code lights are and I cross refrence the to the manual and it tels me initializing ide drive controller and hangs there.The led's never change,it starts like that and stays.The similer thing happend before and I upgraded the power supply and it worked.Then I found this forum and I noticed bad caps .So I replaced the ones that went bad and tried that.Comment

Re: is my power supply bad?
The other similar caps on the motherboard are also likely to be on their way out, so it's normally recommended that you change all caps of every series that is known to be bad, not just the bulging ones. Do that first, and then test with a known good PSU.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles... -
I have a 15 - inch Retina MacBook Pro from the mid - 2014 model. Here is the link: https://www.badcaps.net/forum/showth...light=820-3662 . The battery broke some time ago. After I removed the battery and plugged in the original power adapter, the MBP could boot up normally. However, when I checked with IntelPowerGadget, I found that the CPU speed was limited to 0.8 GHz, and it ran very slowly. Later, I found a solution on GitHub. There is an open - source project called cputune that can set the CPU running speed. So I can now run the MBP at full speed. But another problem...
