New build shows no signs of life...

[CagedWolf]

So I thought it would be a good idea to try to build my own pc, I went from an i5 6600k and a gtx 960 to a Ryzen 7 3700x and a gtx 1660 and it won’t show any signs of life

 

full specs 

ryzen 3700x 

gtx 1660

evga supernova g3 750 w

msi x 570 a pro motherboard 

32gb 3000mz Corsair vengeance 

corsair h100 cpu cooler 

 

I was wondering if anyone had ideas on where I could start to trouble shoot why it’s just not powering on at all, I’ve boiled it down to either cpu, motherboard or psu. I used the ram n gpu in my old build while I waited for the cpu ect that arrived today, any help would be greatly appreciated

Make sure all the cables are plugged in correctly and all the way. (24pin, 8pin CPU, power switch cable)

Is the power supply on?

Yeah I’ve checked everything, I’m starting to think it’s a dead psu, I have my old one but idk if it would be a good idea to plug a 400w power supply into this system? Obv not as a permanent think just too see if I get any signs of life 

 

also so thanks for getting back to me

I think you should be fine for testing purposes, you're not running any sort of load on it. Wouldn't want to use it for more than a couple minutes though.
