I just purchased new set of parts, in particular:
Asus Prime Z790-P WiFi
Intel i5-13400F CPU (+ TUF Gaming LC 120 ARGB Liquid Cooler)
Corsair CMK32GX5M2B5600C36, 16GB*2, DDR5 memory
After assembling Motherboard, CPU (+cooler) and RAM, I turned the power on but nothing had happen. The screen is blank and it even can't make it to the BIOS. The only thing I can see - rapidly blinking power led.
Following ASUS FAQ, I checked memory placement - initially placed DIMMs into A2 and B2 as recommended. However, trying to place only one DIMM (tried in all slots) or another DIMM, nothing helped. The result is the same - rapidly flashing power led.
I am building my own PC systems for last 30 years, this is first time I encounter such an issue.
Any help will be greatly appreciated!
Odd - you do have the 24 pin and CPU power cables plugged in?
What I really meant was make sure they are fully seated. The 24 pin connectors can be really hard to push in fully sometimes. I'm sure you know that anyway, but worth checking. Also the PSU plugs if modular, If none of that works, try different cables and PSU connections. Otherwise, I'd be suspecting a faulty PSU at this stage.
