Solved Just finished building my first pc, won't power on properly.

Parts:
Cpu: Ryzen 2200G w/ stock cooler
Ram: Single UDIMM 8 GB @ 2666 Mhz
Mobo: Gigabyte B450 AORUS M
No GPU; using cpu's igpu
I don't think any other parts matter in this puzzle, though I will tell if asked.

When I press the power button, several things I'm sure shouldn't happen do.
-There is no output. No display, no power to my keyboard and mouse. Nothing.
-My motherboard has four separate warning lights that turn on whenever something's wrong and should remain off. When I power it on, the warning light for RAM is on from the start, and only ever turns off for the CPU light to flicker on and off, letting the RAM light on again. This happens in cycles that last roughly five seconds.
-The optical disk drive will open and close on the press of its button as normal. When taking a disk, I can hear it spin up and read the disk as normal for a few seconds before stopping completely.
-There is no reset switch on my case. Holding the power button for the usual 5-8 seconds to hard shut off just causes the power LED to flicker. There is no power switch on the back of my power supply. The only way I found to turn it off is to pull the power out of the wall, hence why I've only tried to power it on twice.
-After about five minutes, my PSU started to get much louder than I'd ever heard it before. This makes me suspect that a lack of wattage is to blame, though since I have no previous experience doing this it may be something completely different.

Yes, I've tried tightening all the cables, that was what the second attempt was for.
 
After writing this thread, I realized that I never included any specs for PSU, so I took a picture of the side label on its still-packaged twin.
4574

Thanks in advance!
 
my guess is that PSU is way under-powered.
plus it only has a 4pin CPU connector and your mobo wants a 8pin ATX CPU plug.

since you don't have an extra graphics card, i'd be looking at something at least with 550watts.
and don't get a micro-ATX unit like that Replace one, go full size ATX or do you have case constraints to consider.
 
Yes, my case is mATX. Also, the motherboard's manual gave me the impression that four pins was enough and the 8-pin connector was optional.
Thanks for the help! I'll be sure to look for a different power supply with that in mind.
 
I know I've had mobo's with that 8pin connector, and yes, a 4pin did the job, but the PSU's in question were higher than 420watts so I'm not sure if that's a consideration with your issue.

without casting dispersion on your PC building prowess (hell, with my first one, I actually dropped the socket475 CPU and bent the pins I was so nervous and the part, relatively, was so expensive) but I'd be dismantling the whole rig and starting again - second chance, fresh eyes and all that.

if it's not the PSU, other factors to consider are; wrongly assembled, incompatible parts, bad connections, maybe even faulty parts.

To add what Bruce has asked and to help him diagnose.

My motherboard has four separate warning lights that turn on whenever something's wrong and should remain off. When I power it on, the warning light for RAM is on from the start, and only ever turns off for the CPU light to flicker on and off, letting the RAM light on again. This happens in cycles that last roughly five seconds.
Which slot did you put the RAM into? Have you tried different ports?

-After about five minutes, my PSU started to get much louder than I'd ever heard it before. This makes me suspect that a lack of wattage is to blame, though since I have no previous experience doing this it may be something completely different.
Describe the sound. Could be a fan hitting something or off kilter.

Now for the dumb questions.

You did remember to remove the plastic from the CPU and or the Cooling system and apply thermal paste prior to assembly?

You used the proper size and fitting risers between the motherboard and case?
 
Back with a new psu - a Corsair CX750M. It turns out I did my math a bit wrong and that everything adds up to ~500W TDP. No dice, same symptoms as before, minus the noise thing.
I have tried the dimm in all four slots. Last time when using only four pins for cpu it would only fit in the right hand side. I did take both this and the previous psu out of their respective plastic coverings.
The risers might be part of it, or at least a lack thereof. The motherboard didn't come with them, and the old motherboard in the case before this one didn't have any either. The case had little 'hills' around the screw holes, so I thought it'd be fine.
I don't think I did a very good job putting it in the case to begin with. I bumped the motherboard's side up against the chassis a couple times trying to get it to line up correctly to fit, and while I didn't think much of it then, it might be an actual problem. I may have to use that waruntee to get a new board.
 
Testing in minimality proves inconclusive. All I found was that there's a blue-green LED strip on the motherboard that flashes brightly and briefly every time I turn on the PSU; originally misleading me to the conclusion that there was a badly broken power trace on the board.
 
Thanks for advice guys. I got it to work after enough tries. Apparantly I just suck at installing ram consistantly, though I'm sure I got it right at least once before. The documentation on the motherboard is either wrong or just really vague, because I only got it to work when the ram was is the fourth slot, not just any slot as stated by it.
My one problem/question that remains now is:
The fan on my psu sounds really cool to me now. It seems to waver/oscillate in a way that to me says "Your battle station is ready". Just wondering if it's normal or not. Reply if not and close this thread if it is.
 
well done on working through the issues.
those 'hills' are replacements to risers, so you're good on that front.
'banging' the motherboard against the case while installing wouldn't cause issues - unless you are The Hulk!

and the PSU fan will/should waver as it compensates for load, more load = more heat = faster fan speed.
