I know this is old, but thought I'd post an answer just in case.

I think I understand that you want to turn on the PSU to check the voltages, but are afraid of cooking it?

The PSU ON pin needs to be grounded to turn on the PSU.  This means that you should take a paper clip or other wire and connect the PSU ON pin to ground (plug an end into each of the PSU ON and GND pins) and then plug in the PSU to the mains power.

I'm sure you know that you can test all of the voltages by putting one multimeter probe on one pin and the other on a nearby ground pin (with the PSU on of course).

Hope that helps.

Hi all,

I have the above mentioned power supply and have found to be about my only reference after searching.

I would be very appreciative if anyone can join a few dots for me regarding what the "PSU ON" pin needs and and if they also could explain the function of the switch to the terminals it connects to i would see that as taking the inch, and the mile. I Know the bones of DC power supplies and basics in SMPS Power supplies, I've made a few before into suppliers of 12 for non PC applications, but not with the all black wiring plus i know what mac want to do to me overtime i bend over having owned many. (the balance comes from siri giving me the answer to 8x8 for the verification and keeping me dumb)

The problem of where the + and - wires sit can be solved with diagrams, and has been but for the potential possibility of me breaking something trying to get it to switch it on has been put off.

Thanks, any information would help

Всем доброго вечера.
Суть вопроса такова:
Есть синтезатор Korg Triton Rack. В нем есть семплерная функция.
Для загрузки и хранения семплов установлена SCSI опция EXB-SCSI, с разъемом DB25.
Для хранен данных, непосредственно в приборе, хочу установить CF - IDE карт ридер.
Для сопряжения CF - IDE карт ридера с SCSI интерфейсом есть IDE - SCSI конвертор AEC-7722IR
Проблема в том, что в SCSI интерфейсе Korg-а используется разъем DB25, а у IDE SCSI конвертора разъем HD68. Хотел припаять провода напрямую, от платы к плате,
но не знаю какие контакты DB25 соответствуют контактам HD68.
Знаю на 100% что это возможно, но не могу понять что и куда припаивать. В интернете есть примеры, но нет таблицы соответствия этих разъемов.
Для меня было бы очень понятно в таком формате:
DB25 контакт 1 - HD68 контакт 6.

Вот примеры из интернета как это должно быть, там правда клавишная версия, но вся "начинка" одинаковая
Пример 1
Пример 2



Это внешний кабель, а мне нужно спаять внутри.
Заранее всем благодарен за помощь.

P.S.Я не сильно разбираюсь в электронике, но опыт пайки и сборки есть достаточный.

Dear all,

What is the actual power rating for the 24 pin PC PSU Molex connector, for 12 volts?
There are only two pins for +12v, so how many amps is that?

Many thanks!

Hello everyone

I'm looking for the pinout for the Huawei E5220 router battery. I want to build a battery eliminator circuit so that the router can work without the battery connected.

I tried removing the battery and then connecting the E5220 to its charger via a USB cable, but it does not want to turn on.

Thank you
