PSU3300-3 PLUS red light

[matrixpt]

Hello comunity,

I bought brand new psu from china, placed it on one of my 1166, and worked like a charm during 2 hours.

When i picked the machine to place it on the farm, i plugged all, started the psu, and the psu turn on, blinking green led, miner booted, started, but in the moment the minner tried to activate the power for the hashboards, the led turned to be solid red.
The miner remains on, accessible throught web browser, and each, lets say 2 minutes tries to reboot, but the solid PSU red led remains.

 Any sugestions?

If you could access the miner through a browser would you mind sharing the API logs here it can give us more insight into your miner's problem just put them inside the insert code tag so that it is easy to read?

What I see is that the PSU is not connecting properly or maybe it didn't give enough power when the hashboard starting to hash.

hi,

even using the jumper with power supply outside, it should have output from 13v main circuit, and measuring with multimiter, there´s a short beetween +13v and GND,

eventough, follows the LOG

hi,

even using the jumper with power supply outside, it should have output from 13v main circuit, and measuring with multimiter, there´s a short beetween +13v and GND,

According to your logs under PS yes there is a 16 error which is pointing to a short circuit.
Is the short circuit came from PSU? Disconnect the PSU to check it for short circuit and mostly capacitors or some burnt parts are common issue of PSUs.

yes, it came from psu.

no visible burns... witch caps you are refering? the high voltage ones? or the ones near output terminals?

thanks

hi

many thanks, as mather of fact was one 5C430L MOSFET.

I'm talking about caps near output DC or some parts near DC output that might have some corrosions and rust that need to be cleaned with contact cleaner or any electronics cleaner.

Does it seem you found the culprit? MOSFET? Is the output gone or voltage drop after checking the MOSFET? You can desolder that part and check the MOSFET if it is short.
You can follow this guide here how to check short MOSFET.

I'm glad you found the culprit, that's great. If you need 5C430L MOSFET parts, feel free to contact ZEUS MINING.
