I’ll press the power button on my PC, all the lights inside from my motherboard, RGB strip, and fans will flash once and then nothing, it won’t turn on. I’ve unplugged it and plugged it back in multiple time and still nothing. The first time I unplugged it and plugged it back in it made a pop noise, the same kind of popping you here when you plug something into an outlet except this was louder. I think it could be my PSU, it is a (Corsair CX Series 550 Watt 80 Plus Bronze Certified Modular Power Supply (CP-9020102-NA), but that would be ridiculous because I’ve only been using it for like 4 months. Is it my PSU or something else, Please Help.

Hello

After you heard the popping sound,did you smell any burning/burnt or a smell from a short?

[kian2000]

Nope no burning smell, if I unplug my power supply and then plug it back in everything inside will turn on for a second and then nothing turns on after that but there has been no popping noise since the first time it happened

the pop may have been the not too unusual sound when an electrical circuit gets power for the first time.
but my money is on either the PSU dying and/or it letting through a surge and the mobo frying.

and while the age of the PSU may make you think it should be fine, that’s certainly not written in stone.
and why you have a warranty!

[kian2000]

Yah I do have a warranty I just wanted on my PSU, how would I make sure its my power supply and not my motherboard though?

[Bruce]

see if the PSU starts up when disconnected from everything - except mains power.
test described here.

Yah its my power supply, I unplugged everything and then tried to turn on my PSU by itself and it wouldn’t turn on. Is there anyway I can prevent this from happening again, should I increase my PSU from 550W to 600W?

My specs are:
CPU: AMD Ryzen 5 3600 6-Core
Motherboard:Gigabyte B450M DS3H
Graphics Card: GIGABYTE GeForce RTX 2060 Windforce OC 6G
RAM: Corsair Vengeance LPX 16GB
SSD:WD Blue 3D NAND 500GB
HDD:Seagate Bare Drives BarraCuda 1TB
and I’m using a 4k monitor

Yesterday before it broke I was playing Mount & Blade 2 and I had a couple of mods running and it did seem pretty stressful on my PC, I was lagging for the first time while playing a game on this PC and I felt the glass on my case and it was the hottest its been before, I’ve played before and its been hot but yesterday was by far the hottest its been. I don’t know if this has anything to do with my PSU breaking or not, idk.

so it’s at least the PSU, get that RMA’d.
from the looks of your specs, and from what you are saying, I’d be considering upgrading to at least a 650-750watt gold+ PSU.

sadly, you won’t know if it’s more than the dead PSU until you replace that one.
in my experience, it’s about 50/50, that when a PSU dies, other parts get effected as well.
it all depends on how it died - surge, age, dust, fault, water, creepy-crawly.
