Hello, I just got a ga-ep45-ud3p mobo from a friend, not sure what processor is on it yet, 8 of ram, a gtx 750 ti gpu,amd a 650w crossfire ready psu, and a brand new luxo m30 chassis. Up until I did thst my old computer and everything worked fine until I broke my graphics card. Now I hooked everything up into my new chassis and the power shuts off shortly after I turn it on. I never had any problems until after I hooked it up to all this new stuff. I tried hooking it back up to my old computer. Now it's doing the same for both. Does that mean my psu is faulty or shorting out? Ideas please and thank you!!
