[SOLVED] New System won't POST, but it does give beep code when RAM is removed ?

Intel Core i7-13700KF
ASUS TUF Gaming Z790-Plus WiFi D4
G.Skill Ripjaws V Series 32GB

• The system powers on fine.
• Nothing happens though. No video etc.
• If I remove RAM to see if the motherboard at least gives beep codes, it does give the beep code for RAM error. So at least that portion of the board works.
• I have tried a single stick of RAM in every possible combination between the two stick and slots on the motherboard.
• The CPU fan also does not initialize, which is a concerning thing.
• The CPU connectors from the power supply are connected fine to MB

I have reseated the CPU, there doesn't appear to be any pin damage.
I have cleared CMOS

CPU fan never spins even when I am getting beep codes for NO RAM, or when the RAM is back in and the PC is silent.

what is your gpu?
brand and model of the psu?

Thermaltake Toughpower Grand RGB 850W
I have multiple GPUs and I have tried a few of them. 1080ti, 980ti etc..
I have also booted without the GPUs in to see if I got video card beep codes, but nothing. The GPUs function fine in another system.

Just wanted to update this in case someone else has the issue. It ended up being the Power Supply.

Hi,

Just following up on this as I am having a similar issue with the same motherboard and an i5 13400F install. My PSU is an EVGA G2 850W with an RTX 3080 GPU. Same failure mode - no beep, no video but GPU, motherboard and cooling fan all fire up just fine. The PSU is 7+ years old. Was that your conclusion that the PSU just could not keep up even though it has the necessary wattage?

Thanks for any insight!
