I bought a RPI 4b a while back and it finally came in. Well I go to plug it in, and I get nada, nothing, nope, light never blinks or anything. I re-wipe the SD and try again, no such luck, I plug in a fan that came with the waveshore case just to see and it spins up immediately. Ethernet doesn't blink or anything either.
Power supply is https://www.amazon.com/dp/B08C594VNP?psc=1&ref=ppx_yo2ov_dt_b_product_details which should work, my first pi though so maybe not.
Any suggestions on how to test if it's just dead or what I need to do?
Something like this?

Check the polarity of your mount and make sure it is similar to the adapter I linked.
