    Antec Earthwatts 650W

    Dead after exactly 3 months of service. Not even 5VSB. It was in my Mom's machine the whole time which isnt a screamer.
    Just for reference:
    AMD Athlon 64X2 6400+ 3.2GHz (Windsor)
    Gigabyte MA770-UD3
    4x 1GB GEIL Dragon DDR2-1066 (Running DDR2-800)
    Diamond ATi HD3870 512MB
    Pioneer DVD-/+(R)W[DL] SATA
    WD Caviar Black 750GB
    I installed my spare Cooler Master UCP 700W and its running again.

    Warranty time. This is a delta, so even with lower grade Ltecs or taicon's I still wouldn't expect a failure to be cap related as I have lots of delta's with solid 10 years of constant service in poorly ventilated computers with ltecs and taicons that run great.

      IIRC Earthwatts are Seasonic OEM, full of OST.
      I love putting bad caps and flat batteries in fire and watching them explode!!

      No wonder it doesn't work! You installed the jumper wires backwards

        No its a delta, like the JG review sample. Samxon primarys with a grab bag for the rest. I know its wild mass guessing but what would make it fail like this. Its like the fuse is blown.

          Earthwatts started off as Seasonic but later the OEM was changed to Delta.

            I wouldn't crack it open, I would just put through an RMA. Sounds like an unusual failure, replacement should be fine.

              Not sure about the newer Earthwatts, but the EA-380 are full of OST (sometimes a few Teapo) and usually the reason for total failure.

              I opened my 3 yr old Seasonic S12 500w the other week, the internal layout is identical to the EA-380s I've been repairing, but it's using much better caps, there's even a poly cap in there.

                Delta, and that review was over a year ago.

                  Fair enough, they look well built.

                    Re: Antec Earthwatts 650W

                    Wow I've been using mine since December cracked it open to check the caps they used Chemicons on the stressed rails and Ltecs on the others.

                    I also replaced the noisy Adda fan with a low speed Yate loon. Unfortunately the fan isn't speed controlled by temperature (doesn't use 3rd wire) so its running full speed all the time. Luckily for me the YL fan is quiet at full speed.

                    I'd RMA it sounds like infant mortality (manufacturing defect) to me either that or you got hit by a power surge.

                      Re: Antec Earthwatts 650W

                      There's a temperature sensor, the fan speed is controlled directly by temp. Most power supplies use this.

                        Re: Antec Earthwatts 650W

                        So it's controlled by PWM and they don't use the 3rd RPM wire?

                        Guess the temperature is the only feedback.

                          No PWM, one of the monitoring IC's also monitors temperature and adjusts fan voltage accordingly.

                            Ah linear regulation got it.

                              Heads up, Antec has been playing with their OEMs. The EA-380 PSUs don't look like Seasonic builds any more.

                              Looking through the grill, primary cap is a single Samxon, cables are shorter and fewer, with different connectors all placed onto one cable, rather than having one for SATA, one for molex etc. Board isn't stamped ATX 400W rev 5, there's usually a 2200uf 16v cap visible through the back, it's not there. They're rated bronze in the 80+ certification - the old ones may be too, the boxes don't specify.

                              Also, the casing is now army green, they're coming pre-installed in Antec NSK3480 - which we've been buying for years.

                              I'll see if I can get any more details off of the labels tomorrow.

                                Probably delta. Antec seems to slowly be moving their low-medium range to delta now.

                                  370 - Confirmed by Antec Europe.

                                    Antec Earthwatts EA-380 smd element type/value
                                    by sirpsychol
                                    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?

                                    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:...

                                    Hello,

                                    I'm currentlly in the process of trying my first power supply repair (really my first soldering project) and have some questions with regard to which capacitors to replace the bad ones.

                                    The power supply is an Antec Smart Power SL300S ATX12V 300 watt.

                                    I have successfully desoldered every capacitor from the board without destroying anything (I think) and I am currently in the process of choosing which caps to order. This is where I'd like a little community wisdom.

                                    Now the capacitors inside are mostly Fuhjyyus (a forum favorite) with 1...

                                    My dad has been wanting me to build him a gaming rig... nothing too crazy, just something that can run Sufferfest and Zwift (both are electronic bike trainer games) well while streaming (he's on a few teams... at age 64 no less!). A back burner project due to all the other stuff I have going on.

                                    Anyway, a coworker approached me with their teenage son's dead gaming rig... no POST, wanted me to troubleshoot it. Took it on (out of morbid curiousity more than anything)... oh boy, what a POS. This thing is clearly a bargain basement build......
