    Re: Yet another Deer....wait,IT WORKS?!

    Even for a low powered computer, those are really low rated rectifiers. Good job adding input filtering! But honestly, those little caps are so old I wouldn't trust them. They're probably dried out. I would at least replace the two for the main switchers. And if you can handle listening to the fan at full speed, that will help it out

      Actually,those are the rectifiers now:

      5v - SBL3045PT
      12v - SBL2045PT - still works,even if it's 45v VRRM
      3.3v - some 10A part from MOSPEC

      Also,the caps are fine if you mean those around the 5vsb/PWM chip area.

      As for the Delta fan...it's no problem. I have an AVC fan WAY louder than a Delta. In fact,a Delta is barely audible to that helicopter grade fan.

        Good to know. Maybe Deer designed the main transformer so that it has lower output voltages. To compensate, that means the PWM pulses are likely longer. The trade-off with that, of course, is that the power output of the PSU will be much more limited.

        In my opinion, though (stating it just one last time, I promise ), that 45V rectifier on the 12V cuts the safety margin just a tiny bit too close for my comfort. But I guess just wait till next thunderstorm comes while the PC is on. Or plug in a hammer drill in the same outlet next to the PC and give the drill some revs while the PC is benchmarking or something.

        *edit*
        By the way, are you sure that SBL2045PT on the 12V rail is not actually for the 3.3V rail? And the 10A MOSPEC rectifier for the 12V rail? That would seem a lot more logical to me. 10A on the 3.3V rail is only 33W max power - that's very low. Even the crappiest PSUs I've seen usually have at least a 15A part.

          Nope. I carefully checked and 3.3 has a 10A rectifier and 12v has a 20A rectifier.

            Oh good. Those new rectifiers will help it out and increase efficiency. I guess if it works with the 45V reverse voltage rectifier on the 12V, I would leave it but I would leave the power cycles to a minimum. Just put it in a computer and let it run!

                ^ That S16C40C ain't the original +12V rectifier, it was swapped at some time (notice it is much cleaner than the other two rectifiers). As Momaka says 40RRV for +12V rail sounds hairy, better 60 or higher.

                I run a Schottky 20A 150RRV there in my Oh Deer! and it hasn't exploded yet .

                    Also it's been replaced by a 20A rectifier anyways.

                                  Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

                                    Got a case of something new weird at work. There is an old 2nd gen Intel i3 in an old “Pizza box” shell that has a small form factor power supply. Unfortunately I forgot to take pictures and model number off it.

                                    Anyway, I get to work and get to look at this computer. Standby LED on the PSU is on, but the computer won't start. Hmm o.k. take the battery out of the main board try again, nothing. O.k. then… unplug the power supply from the main board and put in a full size ATX PSU (yeeeesss! Exact that blown Powerman IP that I fixed a while back), plug it in and the old...

                                    MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)

                                    Hi everyone,

                                    I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

                                    🛠 Original Issue
                                    The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
                                    Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

                                    I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

                                    ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

                                    Hello mates,

                                    I bought this subwoofer a few days ago used and blind and it works erratically, as far as I could see, it has been tampered with, the speaker is not the original one and of 8 Ohm when it should be of 4, and there are some welds like reworked by the boards.

                                    It doesn't have much power (expected more from it) and it distorts if you increase the volume over the middle, maybe it's because of the high impedance of the speaker. The problem is that it has sound when it wants, the led panels all work correctly, you can hear the power relay on power on, but right now...

                                    by eurowill
                                    Hey ya'll this is my first post on here. I recently aquired a used/broken 2019 mbp 16 a2141 with the 820-01700 board. Seller told me that the laptop needed a new lcd. However upon doing some troubleshooting i found out the lcd is fine.

                                    Laptop boots like a normal, plays chime, touchbar lights up however there is no image on the internal lcd. If i connect and external monitor while its already on, nothing happens and no image is displayed on external. However if i restart or boot the machine while its plugged in, the external then works and a backlight is now visible on the laptop....

                                    EIZO CX270 - No signal but Backlight and Panel works, logo works, admin menu works. OSD doesn't. What?!

                                    Hi, so i guess I´ll have to make a new topic here, as i browsed through hundreds of other threads but couldn't find a solution to my problem yet.

                                    I got a EIZO CX270 from a friend. He said it doesn't work anymore and wont display any signal or take any OSD inputs. Well, as an aspiring photographer I couldn't say no, could I? Thought it was an easy game, replace a bad cap and have a working monitor. But nooope, it wasn't supposed to be this easy.

                                    So let me start with the problem description. I'll try my best not to skip anything so this might get rather long.
