    Artic Power 950w - Not 100%

    Problem: PSU does not allow pc to start

    Testing: Fuse checked fine, primary startup cap fine, ~330v on the primary cap, psu tester does not register anything at all. Apart from the primary voltage I am getting 5.05v at the PS-ON (green lead) and the same at the 5VSB (dark blue lead). None of the other 3.3v or 12v rails have any voltage.

    Question: I can't see anything that appears burnt, cracked or smells bad, the caps (teapo) which I know are poor are not bulged and test good on esr meter. Can you suggest where I can test next? ...also can anyone identify the manufacturer of this unit so I can check for a schematic.

    since it has 5VSB and 5.05V PS_ON, you have much more chance to repair it. the culprits maybe on the secondary side of the psu. try to look carefully that has any burned or stinky smell..

      I hope you do not think you can get 950W out of this supply, you would be lucky if it could do half of that continuously.

      You will be hard pressed to find a schematic for this power supply or any ATX power supply, but you can repair these without one with some effort.

      When you attempt to turn on this supply, do you get any voltage out of the 3.3, 5 or 12 volt rails for even a fraction of a second? If you do then your problem is most likely on the secondary side due to a bad input to the supervisor IC. If not then then the primary side is not getting the signal to turn on or the primary side is damaged.

        if you don't even get anything for a fraction of a second, then check primary switchers, resistors and diodes around them

          LDSisHere I think you have hit the nail on the head there, this was my initial thought when I picked the unit up - it didn't feel that heavy, and when I opened it up I saw the tiny 330uF Capxon primary.

          When you attempt to turn on this supply, do you get any voltage out of the 3.3, 5 or 12 volt rails for even a fraction of a second? If you do then your problem is most likely on the secondary side due to a bad input to the supervisor IC.

          Thank you for this advice - I'll test it and report back

              Peak min/max on something like a Fluke 87V helps find the overload.

              I have an, unsolved problem, ATX power supply and all rails (5 and 12V) grossly overshoot the specified voltages. "Normal" min/max was not fast enough to catch the problem. I had to use peak min/max and two multimeters to see this.

              As a result, the supervisor IC shuts down the secondary voltage, but I have yet to find the culprit.

                  This. I'd check rectifiers as the first thing - if somebody believed that sticker and pushed it too far, rectifiers would probably be the first to blow.

                    I've got a couple of multimeters, but they're nowhere near the same league as a fluke. However, I'll give this a go this evening.

                    So I asked the guy how much he had connected and it was a lot.... 5 hard drives, x2 USB hubs, lots of case fans a decent processor, x2 DVD drives and a meaty graphics card. I believe he definitely maxed it out and was sold on the 950w rating,

                      This looks like HEC, or a HEC knock-off. May be the rectifiers like behemot suggested. When you try to power it on do the fans twitch for a second?

                      And define "meaty" graphics card

                        No twitching can be seen on the fans, and when I hooked up the multimeter's I am only seeing up to 100mv. I am going to take a closer look at those rectifiers.

                        The guy didn't mention the spec of the card, and now he's away for a bit, but I'll try and find out.

                          Now, now...

                          That rating is correct. It'll draw 950 when the PFC inductor shorts and fuse is bypassed...

                              I think you have switching problem . check those switching transistors and Opt-couplers shown in the image . If the switching transistors and optocouplers are OK, then give a voltage check . Measure the voltage of Optocoupler Pin 1 & 2 at normal state (I mean without connecting "Green + Black" condition) . Now connect "Green + Black" and measure the voltage of optocouplers pin 1 & 2 again . This time optocoupler's pin voltage will go higher than the voltage was at normal state . If it happens like that, then your controller section is working properly otherwise not .

                              If the secondary side is OK, then you have the problem in the Primary section and you have to search in the primary side .

                              I hope it will help you find out the problem side ...........

                                  quattro, did you test passive components as I mentioned in answer #4? switchers?
                                  They can be tested onboard, typical failures will result in opens or shorts.

                                  I had identical issue with another p/s - the resistors were cooked to fuck. they changed their rating from 1ohm to something like 1Mohm There wasn't any clearly visible damage to them though. I am not familiar with octocouplers, never had problem with them, but I have swapped them with known good ones as a precaution As it didn't help, i've put the original one back


                                  //unrelated: is there any possibility that by any chance your forum name refers to quattro as and audi all wheel drive system and I have seen you somewhere else on the interwebs? Most likely car related forums. It rings some bell for me.

                                    Is it 0.02V DC in both Off_State and On_state ? At On_State it should go upto 1.5V . That means your controller IC is not working properly .

                                      They can be tested onboard, typical failures will result in opens or shorts.

                                      I had identical issue with another p/s - the resistors were cooked to fuck. they changed their rating from 1ohm to something like 1Mohm There wasn't any clearly visible damage to them though. I am not familiar with octocouplers, never had problem with them, but I have swapped them with known good ones as a precaution As it didn't help, i've put the original one back


                                      //unrelated: is there any possibility that by any chance your forum name refers to quattro as and audi all wheel drive system and I have seen you somewhere else on the interwebs? Most likely car related forums. It rings some bell for me.
                                      I've just tested the diodes and found D5 (UF1007) to be shorted ( I get a reading in both directions). Should I replace with the same or go up a notch?

                                      Also can you confirm what you mean by switchers please?

                                      I managed to get around 330v at Q6 but not Q5 does this help at all?

                                      Yes I am very much a fan of AWD and I am on some of the car forums. But if you want to make the most of that system you need the right rubber... Dunlop wintersport 3D's when it gets cold enough

                                        have a look if there is some small-value resistor nearby, sometimes there is and it makes the reading seem the diode is bad.

                                          Don't hesitate to tell me what i do wrong and if you have any tips and tricks, because i want to learn and improve.

                                          I have a 60w iron that can go up to 450c, cone tip, i usually set it at 400. I applied flux on solder, tinning the tip then applying new lead solder to the joint so that it can mix with the lead free and lower the melting point, then i tried to suck up the melted solder with the solder sucker. But that didn't work since the lead solder doesn't seems to mix with the lead free one. I also tried applying flux to a wick and the board, then tinning the tip of the iron and...

                                          BEST 505 Vs Mechanic Brand Reballing Balls with Lead
                                          by Stanley1843
                                          Hello,
                                          has anyone use these Brands of solder balls? The brand BEST writes on the label of the jar the specs of the solder balls instead of the Mechanic brand. I beleive that BEST brand must be more professional (in labeling at least) but I have never try one of them so I would like your opinion. By the way I hardly can I find the Mechanic brand in aliexpress (the only where I found was lead free solder balls) and on ebay these that I found are approximately15USD per jar. If you know any other trusted brand of solder balls please tell me.

                                          WARNING: Live heatsinks & single pole on/off switches in switching power supplies
                                          by Per Hansson
                                          This is a warning to inexperienced and experienced techs alike:
                                          The De-facto standard is to have the primary side heatsink live in switching power supplies.
                                          That is the primary side heatsink is referenced to the negative of the bulk filtering capacitor.
                                          Therefore never ever touch the heatsink if the device is plugged in.
                                          And even if it is unplugged let the capacitor discharge first!

                                          Another really serious concern is that the power switch also by De-facto standard is single pole.
                                          This means it only cuts power to the phase or neutral (not both) depending...
