No Power at all

[McRazzle]

Hi guys,

 

My computer isn't receiving any power at all. I tried plugging just the psu into the motherboard via the power cable and the cpu power cable. I'm getting no lights, no fan, nothing. I brought it to a repair shop and they said the only non-functioning piece is the motherboard. But upon buying a new motherboard and trying a build with that and once again getting no power I can't see that being the problem (unless this motherboard was faulty from the get-go).

 

Can anyone think of why I wouldn't be getting any power? The wall socket works, and I've tried with 2 different PSU's and motherboards. Could a faulty CPU be preventing me from turning on the mobo?

If this is your first build. Make sure all the cpu cables are plugged in. For some cpu's it required two plugs. If that dosent fix it, since you are getting no power, make sure ur psu cables are all properly plugged in, also it could be that your psu is turned off xD.

It is my first build, however I have had it up and running for over a month, and then I shut it down and it would never turn back on again. The PSU is being switched on, and the cables are firmly in place.

Do you have a amd or intel build.

intel. specs:

i5-7600k

MSI z270 tomahawk arctic

Corsair RM650X psu

Corsair Vengeance RAM (8GB)

Hyper 212 evo cooler

 

But I am only plugging in the psu, mobo, cooler, and I have the cpu in as well.

Did you press the power button on the back of the PSU?

yes

Make sure your 24pin is plugged in all the way. And all your fan cabels are in properly. What I would also do, is take off your cpu cooler, turn on your pc and see if the cpu actually heats up. If the cpu heats up that means that your psu is functioning properly. if it dosent heat up, than either your mobo is fried or ur psu is fried,

Just switch off your pc the second u feel some heat, your cpu will be fine. Its just basic troubleshooting.

If the PSU is working but the mobo is faulty would the psu fan still turn on?

If the mobo isnt working then the psu fan wouldnt even turn on because of the power button on your case. Also make sure your case cables are properly plugged in.

I have taken it out of the case because I want to test it with as few parts as possible. Just the cpu, mobo, cooler, and the psu. It didnt work in case and its not working out of case

You need a power switch to turn on the pc, so it shouldn't work out of the case. Also when you had it in the case you probably had the case cables in the wrong spots on not secured.

my psu has a power switch on it, why would I have to plug it into my case to test the motherboard? when my pc was working I would turn it off by the button on the case and there would still be lights on the motherboard that stayed on.
