PSU's put out several different voltages if the 12Vs isn't working it won't power the motherboard. Some outputs may still be functioning therefore you may see some lights on and even some fans running. Replace the PSU.

HP P4SD, its running good with 4 gb RAM, P4 3.0ghz, and a couple sata hd. The problem is the fan output voltage, i havent been able to read the output chassis and cpu cooler pins voltage cause i can find...


"i can find my dmm?" did you mean CAN'T?
"its clearly off", what is off?
the fans are 3 pins,2 are power, one is RPM tachometer.
"it all works fine", so you can boot and run any OS, ?

"the voltage reads +12vdc", where, at fan or PSU?
the fans run off 12vdc, they are DC motors (from outside fan)
if the fan runs slow at 12vdc the the fan is bad or is a low RPM
fan, as some are, bigger fans run slow, for less noise.!

first is the CPU fan it must run full speed, if not the CPU will overheat in seconds and ALL CPU shut them selves (by there selves) this way. so CPU fan is first. what does it do... there....?

then BIOS screens. GOT BIOS UP? and running? with, ESC key pressed>.
let me guess your symptoms
1: PC dead. will not boot.
2: BIOS dead.
3: all fans DEAD,.
4: power switch works and all PSU voltages read right, (seems not)/?
5: if the PSU power wire reads right(DMM), matching the side sticker voltages, and the CPU is dead, the MOBO is dead, or CPU is toasted.


here is a modern PSU, sticker.
see 5 to 10 power lines, see them. all must read correctly
if a fan is dead, then its dead if 12vdc is present on the fan power pins.

Go to this link. Click HERE. Unplug from the motherboard FIRST. (all other leads too) You can test by using a paper clip to short pin 14 (green) to 13,15,16, or 17. This will power on a working power supply.

Ultra 350 Power supply very loud fan


Hi,
It's not normal for the fan to be loud, what makes them loud is either a build up of dust on the fan blades or the bearings are going on the fan itself.
If the PSU is working fine then you can replace the fan itself from an identical PSU. It does mean taking the PSU out of the computer and fitting the fan yourself.
Alternatively you can purchase another PSU.



Regards.

Power supply won't turn on


You may have a failing motherboard or power supply unit (PSU) then. Just because a mobo has a light on it does not mean that it is getting enough power, just enough to turn that light on. Failure of motherboards and PSU's are usually due to breaking capacitors. A few years ago a capacitor company stole the "recipe" for making capacitors from another company and tried to make their own, unfortunately they did not get the ingredients right and the capacitors started breaking after 2-3 years of use. They sold these capacitors at very cheap prices and a lot of computer companies and power supply makers bought them. This is easy to diagnose. Look for capacitors (caps) (they look like little tiny soda cans) on your motherboard (mobo). They should be perfectly flat on top and not bulged or swelling or leaking anything. There is something in the computer that is not getting enough power and causing it not to start. There are a few companies that will repair broken capacitor issues, if you find that you have that problem. Also if you add a bunch of extra components without upgrading the power supply you can suffer underpowered situations and that can cause internal parts to fail. Have you added any big video cards or extra drives?
And remember a bad PSU does not mean no power, just not enough to run the computer. If you replace the PSU make sure that you replace it with one of the same or greater output watts. Output Watts should be listed on the outside of the PSU itself.
I would try another PSU first if the mobo caps looked good.

Look for capacitors (caps) (they look like little tiny soda cans) on your motherboard (mobo). They should be perfectly flat on top and not bulged or swelling or leaking anything. There is something in the computer that is overheating or not getting enough power and causing it to continually reboot and now just shutdown. There are a few companies that will repair broken capacitor issues, if you find that you have that problem. Also if you add a bunch of extra components without upgrading the power supply you can suffer underpowered situations and that can cause internal parts to fail. Have you added any big video cards or extra drives?

Since you have tried another PSU I would suspect the motherboard or even the processor (slight possibility). What is happening is that the computer cannot even perform the POST (Power on self test) so that is why you get the blinking light.

How to install it.. It just won't fit


Specification::
PSU | Standard ATX PSII

That is what is listed on NCIXUSA.Com. If this PSU you are talking about is a "Standard ATX PSII" PSU, then it will mount the same way many other mower supplies mount. If not, it should still fit, but its not supported. You should always do research before your purchase, and Im sure Thermaltake could have provided the answer and still can tell you how to mount it.

is there a problem you are encountering? does your pc shutting down? what is your present power supply wattage? if that is 300watts then you can change even 450watts.
