Hello, welcome to building your PC for the first time. I understand you're facing some confusion about your setup. Your Sonic Z790 PG seems to light up when you connect the PSU, but nothing else works. When you try to power it with a screwdriver on the power pins, it doesn't respond. Your case has a power button, and you're connecting the CPU as per the manual, but still nothing happens. You mentioned having two cables for the 4090 GPU and four for the CPU, which is puzzling since you thought it would be simpler. I see you've attached pictures of the PSU and the motherboard layout. Let me know if this matches what you expected. Any clarification would be helpful, and I'm here to assist!
Here are a few alternative phrasings of your message:
- I attempted some cable organization, but I wanted to double-check everything functions properly. You can see the front panel cable connected here, and the 24-pin connector for the motherboard is also plugged into the power supply. I was unsure about the blue cable but think it connects as described online. I also shared a photo of the setup after connecting the PSU, and the lights are working.
Begin by testing the parts. Disconnect non-essential items one by one and attempt to power them up each time.
I disconnected all components except the 24-pin M.ole cord and the PSU, yet it functioned the same. I also attempted to boot the PSU alone using the M.ole power adapter and had fans running, which helps confirm the problem isn<|pad|>’s not the PSU. As for what’s essential, it depends on whether you need basic operation or more advanced features.
The essential components needed to boot up a PC are the power supply unit, motherboard, processor, one RAM stick, cooling system for the CPU, and if your CPU lacks integrated graphics, a graphics card. If you're focusing on this list and the RAM doesn't fit in several slots, it's likely time to start sourcing replacement parts—especially the CPU and motherboard—for repairs. Others may suggest different approaches.
Also a big concern. Why does the PSU have five PCIe slots when I only use four? Should I be utilizing all five? Also, do the CPU cables connect directly to the PSU rather than going through it?
The extra sockets and cables for the PSU mainly offer choices. Different users prefer varying amounts. You don’t have to use everything. Just what you require.
