Pc no posting and usb not working

[Eb2000]

Today I went to Micro Center and bought a new

CPU, motherboard, fans and RAM. I installed them and all my pcs fans turned on like normal but there was no signal and my mouse nor my keyboard would turn on. The only ush that works is my Bluetooth adapter has its light turned on.

Anyways here are my specs. New cpu: AMD

Ryzen 5 7600x Old cpu: AMD Ryzen 5 3600

Cpu cooler: AMD wraith stealth

Gpu: r× 6600xt (I'm aware of the bottleneck the new gpu I wanted was out of stock)

New motherboard: asus 650-plus prime Old motherboard: msi b450 tomahawk max

New ram: g.skill flare ×5 ddr5 1×16 16gb 5600mhz (it came free with the cpu and it was the last one before they ran out of stock) Old ram: g.skill ripjaw ddr4 2×8 16gb Psu: 550w 80+ bronze Case:Lian li lancool 2 Storage: I have a sata Ssd as my boot drive and a m.2 as a second drive.

If anyone can help me tell my what I can get that would be amazing and if you need anymore info, just ask.

The 7600x has iGPU, do you get any signal/post when plugged directly into the board rather than the GPU?

Nope same thing is happening with the igpu @Skiiwee29

Try the RAM stick in each of the slots on the board and see if you have an issue with either the memory controller or the RAM stick itself.

After trying the ram in each slot nothing changed and even after running the pc without the ram nothing changed. Also every time I turn it on I can turn it off using the power button I have to use the switch on the psu. @Skiiwee29

PSU way under-powered for your new system. I had a 550W in my year 2004 PC.

Get a brand name modular 750W-850W PSU (gold or platinum preferred).

Alright I’ll try that asap
