    Corsair 400W PSU w/one bad cap

    I've got a 400W Corsair that works fine. But upon blowing out bunnies I see one bad cap, bulged a bit, and I was thinking if I replace it I may save other caps and the unit itself.

    It's had a lot of use, maybe 6 years and been 'on the shelf' for 1.5 years now. All measurements are w/in spec.

    Think it's worth replacing the one cap or just use it again until it fails? As I understand it modern mobos have built in protection from bad PSU's.

    Read thru a third of 500 hits on a search and nothing quite like my situation so far. What do you think?


    Thanks,

    Mac

      replace any bulged caps asap.
      i'v never seen a motherboard that cant be slowly cooked or simply blown to shit by a bad voltage from the psu.
      specially as chances are the bad cap is for the 5v standby line that runs 24/7

          Here's what that one cap looks like, as well as the unit.

                  Yep, looks like the caps (at least what can be seen in the pics.) are OSTs (mediocre brand at best) as well, if you don't replace them all now chances are they will fail in the near future (since all the caps are the same age and brand if one failed the others are likely to as well).

                          Why was the first thought I had the Original CX400??
                          Well, maybe because its around 10 Years Old.

                          Anyway, that's an RLX one, right?
                          Ultra Low ESR one??

                              Random Shutdowns/Startup Failure with Corsair SFX 450
                              by h0m3w0rk
                              Hello everyone,




                              I'm encountering a frustrating issue with my Corsair SFX 450 power supply. After an undefined period of operation, my PC will either suddenly restart or, in some cases, it won't start at all until I disconnect the power cable and reconnect it. This erratic behavior occurs intermittently, making it difficult to pinpoint the exact conditions under which it happens.




                              For context, I have tested the PSU using an electronic load at 150W, and under those controlled conditions, it functions flawlessly. This leads me to...

                              got this tv from a friend who got a new one and didnt want to bother repairing this one.
                              he said it sometimes would just flash color patterns.
                              and sometimes it would just work
                              i figured it had some intermittent mainboard issue.
                              i stored it at home for a while before looking at it
                              when i plugged it in for the first time, i heard some popping noises
                              and then a big cloud of white smoke came out of the back of the tv!
                              i noticed the smoke didnt actually smell like anything. not like when an IC blows.
                              i unplugged it and took the back off and discovered...

                              Corsair HX1200 connected w EVGA molex cable, 12V pin back feeded to 5V. Anybody has experience in this damages repair?
                              by coinwizx
                              The power supply is 2020 Corsair HX1200 modular power supply.

                              Cause of damage: I connected EVGA molex cable to the Sata port and test it with a ATX tester. Since the pin out on the EVGA is wrong, result in the 12V pin shorted to the 5V pin, in the 12V back-feeded to the 5v port.

                              Damage: Power supply shorted out, shut off itself internally, damaged the 5v or 3v rail or the monitoring circuitry. The self protection circuit shut off the power supply when power up because it detected some abnormal/defect. I waited a few minutes, let it self reset then try to re power up....

                              Dead corsair VS450 with blown TNY chip (cwt)
                              by zunasthegreat
                              I have this Corsair VS450 PSU which lies dead and has an exploded TNY chip. Upon removing primary side parts like mosfets, the bulk cap and the bridge rectifier I've found that the primary cap is also a goner. (Photos)
                              The mosfets and the diode are fine and survived the collapse it seems. The TNY chip is shattered and from the online review/sources it was probably a TNY176~177....

                              Corsair RM1000e - Help identify 5VSB Zener diode
                              by hobostove
                              Hey there guys. I've got a Corsair power supply that's come across my bench dead. I usually don't mess with power supplies, but it's a slow week so I'm giving it a whirl.

                              Taking it apart I heard a screw rattling around inside, and when I got it apart I found a couple blown components near what I think is the 5VSB area.

                              There's a 22ohm resistor that's melted and open, but it still has the bands.

                              The other part is a zener diode and it's top went to jesus, so I can't read the marking.

                              It looks like the diode connects the source and drain of a TNY284...
