    Antec TruePower 430w

    Hi, i have a problem with my antec tp 430w.
    5 years ago I replaced all Fuhjyyu badcaps with new samxon cap thanks to BigPope and my psu works fine so far.
    Yesterday I push power on button on my pc but it will not start. PSU don't start but the 5v SB line is OK. I opened the psu and all the capacitors look normal. What could be the problem?
    Thank you very much and sorry for my english.

      Does the psu fan move for a sec?

          No, no signs of life :-(

              It's possible (though not the likeliest culprit) that the primary side 400v capacitor has failed
              You would need to do some tests with a multimeter with the PSU live, in all I don't recommend this of course due to measuring at live circuits, very very dangerous unless you have the proper training...

                  ^ if that's also Fuhjyyu, it's more likely than usual.
                  i've seen bulging primary Fuhjyyus in Antecs before (Truepower 550 EPS)

                      I replaced now the primary cap,but nothing.

                          I've seen PSUs refuse to start because the fan is jammed. Must be current monitoring, because most only have two-wire fans.

                              Or something failed because of extreme heat due to its very silent design.

                                  Disconnect the power supply from the computer, then plug the PSU in the wall. Measure the voltage with a multimeter between a ground (black color) wire and PS-ON (pin 16, usually green) wire on the ATX connector. Let me know what you get. If you get no voltage, verify that 5vsb (pin 9, usually violet) is at 5v or within 5% of 5v.

                                  See this article if you need help with the pinouts on the ATX connector:

                                      Antec TruePower 380p failed after intermittent supply, suspect MOV
                                      by rabbituk
                                      Hello,

                                      I have an Antec TruePower 380p PSU that I had repurposed from a Sonata case. It had been working fine on a server in the loft using the Wake-on-LAN feature regularly until a couple of recent power outages where the power became very unstable - going on/off very quickly. There is now no output whatsoever from the PSU & fan isn't working. There was a pop when I attempted to turn it on.

                                      Upon examination, it appears that voltage isn't getting very far so I believe the immediate issue is within the first stage. There is a green component that I am not familiar...

                                      EVGA 430W PSU Correct voltages but computer won't turn on
                                      by objecttothis
                                      I had a desktop form factor mini-server die on me a few weeks ago. Through my initial diagnostics, I was convinced it was the motherboard because when I shorted the Green wire on the ATX connecter, the multimeter gave me all the correct voltages on the various pins of the ATX connector and 5VSTB was also correct. To my surprise the replacement motherboard wouldn't turn on with the case power button either. I threw in another PSU and it turned on right away. This is an 80 Plus EVGA 430W PSU with PN:100-W1-0430. I pulled the cover off and don't see any immediately obvious blown caps or scorch...

                                      Yes, I know I don't post this stuff much anymore....the only reason I'm posting this one is because of a NVMe adapter incompatibility; seems rather planned by Supermicro.....or I'm atleast a bit suspicious. It's plenty new enough to have a UEFI bios but a short 'happy list' of NVMe controllers that will work with this board, as if by some 'miracle', all Intel....so lets start at the beginning; we'll get back to this later.

                                      Of course the motherboard is as the thread title states; X10dai....but we'lre going to have some fun shoehorning this into a modern 'gamer case' that can actually...

                                      Antec Earthwatts EA-380 smd element type/value

                                      While recaping Antec Earthwatts EA-380 I've broke one side of unknown smd element, it have no print, it's flatter and darker than smd capacitors on this board, shaped more like resistor but it's not resistor ofc. Unfortunetly the printed description was under it and element was glued to the board so I cant read/tell the letter before element number too. Have anyone any idea what it is? Maybe is there any diagram of this PSU?

                                      Picking caps for Antec SU-380
                                      by ajdrenter
                                      In my search for a proper 5v heavy ATX power supply, I selected an old Antec SU-380 that I've had in storage for a long time. Opening the power supply reveals a couple bulged capacitors. I removed all the caps and made a map for myself. I found the datasheet for the PCE TUR series in this thread:
                                      https://www.badcaps.net/forum/showthread.php?t=14159
                                      It says these are general purpose, so I assume I can replace them with any general purpose capacitors, but I don't really know anything about power supply circuits or reading capacitor datasheets. Despite this, I've been shopping for replacements:...
