hello guys! I'm from Brazil, I have already burned my HX1000 a long time, and now I want to revive it. I just want this "conversor DC-DC"

I believe that any converter from any psu HX series from CORSAIR will work in my HX 1000, what you guys think guys?

I tried to contact CORSAIR forum but they blocked me, I tried to find someone with a hx psu that has the drive that could sell
support also reported that they do not sell parts or make repairs
I thought about doing the same without the RMA warranty seal, what do you think?

Hello. I had that same problem with my Corsair HX1000. I bought one as burned one for repairing it.
All you have to do is to replace the mosfet transistors Q24...Q27, the control IC U11 and maybe the 1n4148 smd diode. The IC is the APW7073. After checking the datasheet of the APW7073 and the corsair board i think that you have to replace the resistors R178, R217 and R182 to 2.2 Ohm resistors. I can`t get original mosfets in my country and i replaced them with IRFR4104. Doing that i had to recalculate the OverCurrent and ShortCircuit system (just replace the R173 with 1k resistor).
I checked the board for shortcircut and it worked fine.

If you want to get this PSU working well i also recommend to replace the resistors R178, R217 and R182 in the other board as well.

oh man, i am so happy with your answer!
but unfortunately i do not understand anything about electronics :(
you said "recommend to replace the resistors R178, R217 and R182 in the other board" what other board? the other conversor ?
My PSU works fine, but there was an accident and a wire touched the converter and the converter burned, I think the other converter is good
You do not recommend a person to do the repairs?
I'm sad to see my dead hx :(
sorry for my english

Like i said i bought this psu on internet auction as burned one. In my case the 5v converter failed. I did all the things described and my HX came alive. The psu was working but i checked the 3.3v converter. I noticed that the transistors on the 3.3v converter were very hot even with no load on it. I replaced this transistors as well. The converter is controlled by the APW7073 as i mentioned before. The converter is very similar to the one in the APW7073 datasheet except the three resistors. I trust the APW7073 desiners more that the corsair ones so i replaced the R178, R217 and R182 on both 5v and 3.3v converters to be sure it won`t burn again. In your case, you can only replace the transistors, APW7073 and the diode D4 (it was burned in my case). Depending on what transistors you will choose you have to replace the R173 with the correct value aswell (the OC limit).
If you have some skills in soldering smd`s i can guide you how to repair your psu, if not i recommend you to give it to person who have the skills and some knowledge in electronics.

tanks for answer man!
but I live in the middle of the Amazon rainforest, my city is small, and I know not a good professional :(
and I do not venture to make repairs in my PSU

Every service could do the repair. Good professional is not needed, only a person with soldering skills. If you have a electronics shop go there and ask about some electronics service nearby. Otherwise you wont repair this psu. I doubt that Corsair will sell you the dc converter.
