Hi guys, a noob here in PC building. My PC gave me display when I used the PSU outside the cabinet just to test. Now, I'm not getting display. My GPU and CPU fans are working. I can't see an orange LED on the mobo which comes only when display is working. I have tried 20-30 times, I got display only 3 times, what could possibly go wrong? Need help.

My system is :

Ryzen 5 3600

Samsung 980 Pro M.2 PCIe 4.0 NVMe SSD

Aorus X570 Pro Wifi mobo

Deep Cool 850W SMPS

Zotac RTX 3090

GSkill RipJaws 32 GB 3200 MHz DDR4 Memory (1x32 GB)

Antec NX200 cabinet

Which psu exactly? You use two pcie cables -> one connector each? (first one) If not do so.

Check the 8pin EPS connector as well, is to power the cpu.

Yes, I'm using 2 PCIe cables and connecting them via adapters that came along with the Zotac Box. CPU is being powered via the 8-pin connector and connected to the part of the PSU where CPU is written and GPU to the parts where VGA/CPU is written
