All parts are brand new.

Asrock GENOA2D24G-2L+
cpu : 2 x epyc9354
ram : Kingston KSM56R46BD4-64MD 64GB 2Rx4 8G x 80-Bit PC5-5600 CL46 Registered EC8 288-Pin DIMM
Some 3U cooler for cpu
psu : ATX Cooler Master MWE Gold 1050 - V2 Full Modular

I use modded cables for ATX from moddiy :
ASRock Server MicroFit 4 Pin to Cooler Master 10 Pin Adapter Cable ( Micro-Fit Power Connector (ATX4PIN1) )
and
ATX 12V Power Connector 8 Pin Power Cable for ASRock Rack and Cooler Master

When I connect the PSU to electric power, 2 green led diodes start flashing on mobo- one is for BMC and other is STB PWR ready.
When I push start button on mobo, fans start for second and stops .

Im wondering, if any body use this motherboard with ATX psu to share info with me, is this all cables that I need.
Is anything that I mising, I can't fugure what is the problem.
