    PSU dying? (Video)


    Hello,

    I believe my PSU is dying, it's almost 5 years old, I've been using it since December 2008, average 8h per day, no CPU OC. Please watch video, loud buzzing noises initially sounded like coming from MoBo, but I've removed PSU from case so I could listen in detail and it's definitely coming PSU. So far symptom sequence is:

    1 - From 1 year ago approx. I've start to hear some buzzing noises, apparently from the CPU/upper Mobo capacitors, I've searched on internet, and general opinion was that it was a normal noise, the noise was intermittent.

    2 - From 1 month ago, it started to shutdown suddenly, no warnings, no BSODs. It was mostly when I've resumed from hibernation, so at the time I assumed it was a Windows power management issue. After 3 weeks of normal activity, playing games etc. I had no problems whatsoever until last Friday, I was simply on internet and it suddenly shuts down. Restarts and shuts down again 5 seconds later. Now it keeps stable just with internet activity, if I test it with JAM's "heavyload" or if I play any games, it will shutdown 5 seconds later.

    3 - In the last few days, I've been noticing HDD spin off and water pump restarting.

    What I've done so far:

    1 - Removed PSU from case and connected it externally to MoBo.
    2 - Swapped power cables and SATA/PCI cables.
    3 - Have tried different mains sockets, all have the same result.
    4 - The PSU was heavily populated with dust, I've cleaned it all.

    System specs are:
    i7 920 @ 2.66
    1 x SSD
    1 x HDD 1TB 7200RPM
    1 x HDD Green 2TB 5400RPM
    1 x alphacool water pump 11W
    1 x MSI GTX750Ti (although I've used ATi 4600HD 512mb overclocked to 1000Mhz for 4.5 years).
    6 x Corsair XMS3 sticks (8 GB Ram)
    5 x 120mm fans
    1 x USB sound card
    PSU = NOX Pulsar 650W (I'm aware it's not a very popular PSU brand)
    Windows 8.1 X64

    I don't know if it makes any difference, but the PSU is top mounted, and the fan spins intake-wards.

    Did not need the video. Five years old. Most likely some bulging capacitors. Time to change it out. You could take it to a local mom & pop shop and they can use a Power Supply Voltage tester to check it out. Also the longer you operate a dying Power Supply. The more chance of killing hardware and the motherboard.

    You can get a tester for Power Supplies for under $5. Amazon.com: eForCity® 20 / 24-pin Power Supply Tester for ATX / SATA / HDD, Black: Computers & Accessories

    Hello there blz.
    Five years of average use with a non top notch PSU,should be considered more than enough,it paid out well.Your symptoms,do indicate that maybe its time to move along.Be "generous" to you and your machine and buy a good,reliable and a bit bigger power supply for future upgrades.
    You could measure its voltages,if feeling handy enough and performing the infamous paperclip trick with a multimeter,see if its rails do provide stated and stable outputs,but i wouldnt trust it,since it would be without any load and therefore not really stressed out like IN the machine.
    Do not attempt to open and fiddle with it by any means,them devices are pretty dangerous,even when unplugged or considered dead,they are still loaded with lethal power!

    I have just average skills with a computer, so please help me. When I delete a program, how can I make sure all data for that program is gone. I got Revo but at times a download might go to Windows 8 ( programs and features ). When I remove a program on Revo I can delete all the files. Not the case sometimes with Windows ( programs and features ) sometimes thay don't delete very easy. Thanks, Chuck

    Cheers, I think I'll skip the power tester anyway, I'm practically sure that something is wrong with the PSU, and it makes sense considering it has 5 years old, anyway it lasted very long as NOX is made by super flower and not so well rated as Corsair or Seasonic. Well, I've open the PSU case just for the clean, I haven't touched anything, as far as I know the capacitors all looked good, no leaks. Anyways, it's time to move on and change to a more efficient PSU, I am considering either Corsair CX600M or Zalman Goldrock ZM550-XG 550W, hopefully I won't have to worry too much for 3 years or so.

    Hello again. I've got bad news. OK my PSU was emitting weird noises, but the problem remains. After installing new PSU, the GPU was not working, then I re seated the GPU board and it worked fine, however just before logging on to windows it had another sudden shutdown. I hear buzzing noises coming from CPU area, I can´t say if is MoBo or CPU. One thing I´ve noticed and is concerning me. My water pump is the Alphacool AGB-Eheim 600 Station II 12V, it uses a PCB to power the pump. On that PCB on of the capacitors was detached and I've glued it again, it seems that there is no contact problems as the pump is working fine, but I wonder if that may eventually cause any problems, I cannot test stability with the pump off, as I got no CPU fan to replace. Another aspect is that I often hear electric buzzes (not like coil whine, something stronger) coming from the MoBo, definitely there is some sort of electric problem and I feel real frustrated because I cannot locate it. Is there any possibility of bad CPU? I mean, I wonder if my old PSU eventually ruined any of the components...

    Hey there,personally i have never heard a CPU failing with a bang!You sure the pump is fully operational?Can it be that by malfuctioning pump,you are getting temps that high,that it eventually auto shuts down your machine?Or was it a one time only?
    You have got to find out where noises come from.Take a straw and block your PSU fan if you have to,wont mind for a view seconds,unplug noisy HDDs,block your GPU fans aswell,check for "swollen" ,bulgy capacitors on your board.
