ASUS B350-F Strix's RGB and orange LED light up but nothing else works?

Parts list:

What I've done to try and fix it: I've tried rewiring everything, I've tried using another power supply, using different ram slots, and using different pcIE slots for the GPU. However, I still cannot get anything to post. The RGB on the motherboard as well as the little orange light at the bottom right lights up, but the GPU lights don't light up, the GPU fans don't spin, and neither does the CPU fan. One note of importance might be that the pins on my PSU's 2x4 pin CPU connector don't match the ones on my motherboard, but they plugged in fairly smoothly with a little bit of force anyways. The pins on my PSU look like this while my motherboard's connector looks like this: . I searched that up online and it turns out that the PSU maker (EVGA) decided to key only one side to save money, but I figured i might as well include it just incase it has anything to do with my issue. Any help is appreciated. Thanks!

I looked at the manual for your motherboard, and also at your PSU.

The pic you provided for how your motherboard looks doesn't match with the manual, or the pictures Asus provides (or even retailers like Newegg). The pic you provide shows a motherboard that uses not only the 2 x 4 pin CPU connector, but an additonal 4 pin connector for heavy overclocking, and that is not something that put on their entry-level boards like the ROG STRIX B350-F Gaming.

Your PSU connector has a standard split 2 x4 pin CPU connector that should only go in one way, and it shouldn't need forced in there. Maybe you jammed in a wrong connector, like a PCIe one which would be very bad.
