Re: Power Supply Problem
Test the motherboard on another power supply, there might be a problem on the motherboard.Muh-soggy-knee -

Re: Power Supply Problem
When you jump start it, check The voltage of the grey wire on pin 8 (PW_GOOD.sigpic

Re: Power Supply Problem
Often in the beginning of a capacitor problem in the PSU, it can turn on and run with no load but can't stay stable with a load (motherboard, etc, connected) so it shuts off within milliseconds after turned on. Take the lid off the PSU and look for bad (vented) caps.Comment

Re: Power Supply Problem
@ben7 I tested it on another motherboard but it still not give power.
@selldoor the motherboard i used is P4M900-T and MSI 7525. well the power supply i bought is the generic type. it says on the sticker "RISE"
@ratdude747 I will try that. but what voltage do i need for the result?
@999999999 okay i will check that. and provide a pictures.Comment

Re: Power Supply Problem
Hi I see RISE is a common make/label in the Philippines. Did you just buy it new
is it still under guarantee. Picture of its label and the connectors might helpPlease upload pictures using attachment function when ask for help on the repair

Re: Power Supply Problem
I found a old power supply. It has the same problem. and I saw this. Is this causing the problem? and what part is that? I dont know what it is called.Attached FilesComment

Re: Power Supply Problem
"I opened it and i see this. is this the problem? sorry i dont have a HD Camera".
I dont see anything wrong in the picture- try one less close up
"I found a old power supply. It has the same problem. and I saw this. Is this causing the problem? and what part is that? I dont know what it is called."
The coil part is a Toroid Inductor or Choke. They are usually very stable and
do not cause problems. My guess it has been damaged by association with other components possible the ones on the heatsink. Or it has had liquid spilt on it when working.Last edited by selldoor; 06-02-2012, 02:54 AM.Please upload pictures using attachment function when ask for help on the repair

Re: Power Supply Problem
Yes the PSU is damaged, try a different one.Comment

Re: Power Supply Problem
That would be an iron powder toroid. They can be used for power filtering and in boost and buck converters depending on exactly what material they are made of and how the wires are wound around the core. Similar in operation to a transformer but yet at the same time quite different.
When a power supply dies as in manner of the picture you have shown, its pretty much ready for the garbage because even if you could find a suitable replacement the power supply is likely to have many more serious problems.Comment

Re: Power Supply Problem
About the other PSU you pictured. It's a generic brand (Rise) claiming 600W that seems very low quality. Look at the bridge rectifier diodes, they are 3 amp rated at most. <> 600W
Even if the unit is operating within its intended design capability, it may simply not be able to supply sufficient inrush current to get the system rails stable in time on power-on.
Your best bet is to abandon both PSU and find something that's better quality.Comment

If you still want to look at a repair on the Rise please provide more pictures.Please upload pictures using attachment function when ask for help on the repair

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... -
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.
Assuming... -
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... -
hello
i have a power supply adjustment like image
i want turn on asus vivobook with type c charger
i want a connect type c cable to power supply adjustment but type c cable have 3 wire and i don,t know how to connect the cable type c to power supply adjustment
