Hello,

I got a PSU that blows the housefuse(10A 230V/50Hz(I live in Denmark)). There is no warrenty on it, so I'll like to see if I can fix it.

 

PSU = Cooler master G650M

 

Results:

- PSU plugged in but switched off = No blowen fuse

- PSU switched on (and plugged in)= Fuse blows instantly (Not connected to a pc, and psu is NOT "shorted" (papirclip test)) So no load

- Can't test with load

 

I can measure 1K ohms between L1 (phase I think it would be called in english) and N (neutral). I would think that this should, atleast be 1M ohms.

I can also measure

~100 ohms between +12V and GND

~100 ohms between +5V and GND

~100 ohms between +3,3V and GND

However all these readings are the moment the multimeter touches the metal. If I hold them for longere the ohms keeps on going up.

I know that information is scarce so if you need more info just let me know.

 

FYI I think it's fun to play around with electronics. I don't NEED to get it working but would like to.
