I recently swapped out my EVGA Bronze 850W power supply for a Corsair 850W Gold. However, when I try to power it on, the fans briefly spin but don't stay on, and the system isn't posting at all. I've connected all my cables, including PCIe, motherboard, CPU connections, and SATA for both my C: and D: drives. I'm not sure what's causing this issue.

Just for reference, what are your specs? Knowing the components can help others offer more tailored advice.
Did you perhaps re-use the cables from the old PSU? It's important to make sure you use the correct cables with your new power supply to avoid any issues.
It sounds like your RGB fans not lighting up might also indicate a power issue. If the fans spin for a second and stop, it could be a sign that the PSU isn't providing steady power. Double-check every connection and try reseating your RAM as well.
Make sure all your connectors are firmly plugged in on both ends. Sometimes a loose connection can cause the system to power cycle like that.
I figured it out! I missed a connector on the motherboard, but once I connected it, the system booted up perfectly. Thanks for your help!
Nope, I made sure to use all the new cables and kept them separate before installation.
