Source EUROTECH FONTE ALIMENTACAO BRONZE FATX750 does not work on hp xeon board

[martin Gerik]

Hello community. Good day
I am contacting you because I need help, I bought this source EUROTECH FONTE ALIMENTACAO BRONZE FATX750 and it does not work on my HP PC with micro Xeon, when I connect it the red light on the button turns on and it makes 4 beeps. I already removed the static from the board and changed the battery, it still didn't work. What else could it be?

Your new PSU looks defective lacking  a pin...

2 things

 

Your psu is missing a pin and defective

 

This psu is NOT a 750w. Its basically another cheap as can be made psu rebranded. Its a terrible unit, will explode if even asked 750w and potentially killing your system

 

 

So the fix is get an actual good psu or at the very least decent

Preferably a or b tier worst case get a c tier.

 

Since this junk seems to cost 40 for 45 a older cx650 is available or even newer evga br 500w units for the same price

Missing pin is a -5v rail which has been missing on every single PSU since late 2000s. Issue is not due to that.
