Swapped out my 8 year old OCZ 1000w Gold with a new Seasonic 850w Prime Titanium. MOBO lights come on But does not power on. Checked all cables they are seated correctly. MOBO uses and 24pin and a 8 pin for main power Checked connectors from power button and reseated them. Still nothing. Plugged in my old power supply and its working like normal. Anything else i could try? Thanks.
