is the Motherboard 4 or 8 pin connector connected? Should be around the CPU

I was just doing some cable management and when I tried to turn it back on nothing happened. I mean it wont even turn on nothing. The 24 pin connector and the front panel are well connected. Idk what im missing.

Check the switch on the power supply and if it's plugged in. It may seem like something you wouldn't forget but I see people forget those all the time. Also make sure your power switch is still plugged in. It can get unplugged pretty easily when it gets yanked

If you burnt something you would smell it. I would try getting another PSU to test it out. You can also test gaving diffrent compents plugged in and test them.

I dont have another one, but why would it be that, thd whole pc is like a week old and so is ths PSU.

Well that simply means you can'tuse the PSU outside of the U.S. A voltage switch is to switch between our voltage in the US and voltage in places like Europe.

That's what it is. Make sure that's on. Also, if you are using a power strip, check that. Have only the computer plugged into it, make sure it's on and plugged in. I know I am giving some obvious ideas but you have no idea how many times I wonder why all my stuff turned off only to find out I Bumped the power strip.

Unplug everything from the motherboard and if your power supply if it's modular. Them plug them back in. Sometimes something isn't hooked up correctly and it is usually hard to trace so it will save you some work

So no one knows the problem? :/

No but I do recommend unplugging everything and plugging them back in. If a cable is in wrong, this would likely fix it.

Do you have an old desktop lying around? You could hook your PSU up to that and see if it works. You may have shorted out your mobo. If it works in another pc, it's likely your mobo if nothing is being powered.

Most modern psu are auto switching. Check the label, if it is auto switching it has something like 100V - 240V somewhere on it.

 

@Chaicho,

 

Make sure the switch on the back of the psu is on. Make sure the wall socket being used is live. Make sure the wall cable is securely plugged in at both ends. Make sure the 24-pin motherboard power is plugged in snugly. And the 4/8-pin additional power.

 

Most motherboards have a power LED somewhere. It should be lit. If the motherboard does not have any LED, make sure the case front panel cables are plugged into the correct pins on the motherboard. If they are, (turn off any sound sources so you can hear low volume noise), press the power button . At the very least you should hear the psu and perhaps other fans spin up briefly. If you don't, I would suspect a psu failure. 

80+ ratings certify electrical efficiency. Not quality.

It's really hard to diagnostic hardware problem via forum post like this. If it's burn you will smell the burn and see burn mark right away. Judging by no light on either the mobo is broken or the PSU is broken. If you have another PSU lying around you can try that, or just bring the PSU and mobo to an IT shop to test

In the PSU, bridge the green wire to any black one, and turn it on. If fan starts, it is working and issue might be somewhere else. If it's not green wire it's purple which you need to bridge to black to trick the PSU into thinking it's connected to a motherboard.

Follow this idea. I think it's the motherboard because most headers are connected to that. Also use the PSU fan headers instead of the motherboard headers for (what I think are but might not be) obvious reasons. I really hope that you can figure out what is going on with your computer. I have had to fix broken computers before and the rush you get when it works again is great. I remember that from when I fixed my laptop's dead bios last week.
