This pc im using(main pc) has a Seasonic core GM-650 PSU and works just fine. But, because my 2ª pc that i use for work has a old psu that is making a lot of noise i decided to buy a new psu for my main pc( the one im using) and use the seasonic on the old one.
I bought a Corsair RM750x but when i plugged it in, it doesnt boot. The front fans spin for a second and then nothing. But when i use the corsair on the old pc with a pentium g4560 and gtx 960 1 hhd and 1 ssd it works.
Plugged the seasonic back on the main pc and its working just fine. What do u think? faulty corsair psu?
My seasonic 650w can boot the sistem but the corsair 750w cant...

Were very lucky Corsair detected a short and hopefully prevented the component from frying. Wish modular cables were universal for convenience but sadly the industry is not. Pin diagram +/- are often located differently between brands and sometimes models. Rule of thumb, only use cables the psu comes with unless you can verify with multimeter.
