New build here, 9700k, Asus maximus HERO XI, rtx 2070 super, 2x16 3600mhz corsair ddr4, be quiet dark rock 4, Samsung 970 evo, 2TB Seagate barracuda and a Silverstone st65f-gs 650w psu. Installed all the components, on the mobo box to test and it all powers up, cpu fan, lights and all; no post, no beeps. I do have this hooked up to my tv (I dont have a monitor yet [trying to find a decent 1440p 144hz monitor]). I tried using system builder to see if they weren't compatible, but they dont show my psu. I can post pictures if needed or if someone wants to face time please let me know.
