I had a corsair cx500m for 8 months and it blew on me. I ordered a new evga g2 550 psu and connected everything, checked the cpu 4 pin was connected etc. When i power on the psu the mobo light is working fine, but if i press the case power button i get a blue flash for a split second and then nothing, fans dont start or anything. Ive tried just booting with 1 stick of ram snd just thr mobo, cpu and gpu but still nothing. Ive tried reseating everything too im really stuck here guys, any help?
