Ok, so I took apart my pc for dusting, just used a small can of compressed air, out of curiosity I tried the paper clip test, green cable and a black ground cable, it works, so I continue doing my thing, blow some air to clear some dust, after that my psu is dead, failed the paper clip test, and wont power up, no signs of life, how strange is that, its a cooler master gx 650 bronze, still working fine before I used the compressed air
EDIT: TOOK APART MY PC! Not psu, sorry for the confusion
