PC build showing no signs of life

K1NG_

Hello all,
Today I began building the pc I've been buying parts for for the last while. I finished building it and tried turn it on. Both power from the wall and on the psu were on but the PC seemed to not acknowledge that any power was going to it. No fans spun, no lights turned on, all buttons seemed unresponsive. I checked all wiring were done correctly but no luck. If anyone Knows anything or has experienced something similar please help.

These are my build parts:
-Intel i3 6100
-RX 480
-CoolerMaster G550M
-msi H110 Pro-VD mobo
-Aerocool aero1000
-An SSD and 8gb RAM

PLEASE HELP!

Did the PSU fan turn on? If nothing is going then you've either wired it wrong or the PSU is bust. That's what it sounds like anyway.

The only thing to do is try another PSU or try that one in another PC. you've got an entire build and to rectify the issue you need to find out what part(s) are having problems.

Try shorting the jumper where the power switch plugs into on the board with a screwdriver, just to rule out that

The PSU fan didn't turn on but I'm almost certain that the wires are done correctly. In what way could the PSU be wired wrong ?

Could this harm the PSU at all?

kingtiger

Nope it's just bypassing the power switch on your case, it might be as simple as the switch is fecked

It's the jumpers where you plug in your HD lights / reset button / etc

Hi,

I used to build them myself. If all hardware is ok then its more than likely a jumper setting on the motherboard and/or the trigger for starting up the supply, usually on the motherboard if you have your connections done ok. Best thing to do is start with the minimum configuration , psu, ram , motherboard .
Look up the spec etc on your motherboard too if you are unsure...
If RAM IS INSERTED incorrectly , it will not boot. I'm assuming also your psu is ok.

I will have a look through the specs and make sure everything is wired in the right place. Was unaware that incorrectly placed RAM could stop the pc from starting. Still no luck but thanks

It won't boot but you're a step back from that. You're not even getting power.

Ah I see

kingtiger

If it wasn't the power switch, you may need to breadboard it, take the board out of the case and plug in the bare minimum and see does she fire up

I'm going to recheck all the wires and check again if it is still unsuccessful I will try short the PSU and check for a sign of life.

K1NG_

I may try that also, thanks.

Hardly just the PSU is turned off? What loose cables are coming from the PSU

Have you a voltmeter you. could check the power supply voltage you would want to understand what your doing shorting a connection I would not recommend this just from a safety point of view.

There is a spare wire coming off the gpu wire which I think is just for dual graphics cards. Apart from that there are no loose cables off the psu.

Ye I could check around the house but I'm almost sure we don't. Cheers

Hi, make sure and disconnect any USB headers to the case and try again.

I've seen people get the cables confused and if they are wrongly connected it will stop the PC starting (and damage the M/B USB's).

I would always advise to disconnect ALL equipment that isn't required to start the PC. So disconnect anything you can do without for the moment like DVD drives / Hard drives, any speaker connections etc.

Remove any add in cards like sound cards etc.

If PC starts then, turn it off, plug in one item and try again. Keep going till you find out which item is the problem one.

Don't have any add on's as this was only a budget PC. I just tried starting without the usb 3 wire in the mobo but still refused to give me any sort of life

do you have the right amount of motherboard standoffs installed... it's always the motherboard standoffs

I saw that somewhere and checked the back of my case I have exactly the right amount of standoffs for my mobo

Have you got the power switch wires connect to the right header?

K1NG_

yes all have been redone numerous times as is on the manual. I will try again though just to make sure

wotzgoingon

Well if the wires for the power switch are on the correct header. Next step is short the power switch just so you know if the switch is faulty.

K1NG_

Just want to make certain that theres no other reason behind this before shorting the PSU

wotzgoingon

It won't do any damage.

Just so you know where to short and not short the PSU.

What you do is short the two connections on the inside of the case on the power switch.

How do I get in to short the wires?

Good question. As all cases and switches are different, I do not know how you be able to do it on your case.

wotzgoingon

Where are you based anyway, maybe someone could help you out.

Find JFP1 and short pins 6 & 8

K1NG_

Oh my god, the wires were plugged into a similar area but as JCOM1 will try with rewired cables and be right back

Mission success thank you all you were a great help. I was to dim to realize what a simple problem it was! Might have more questions during boot. Thanks

wotzgoingon

I knew it had to be the switch was connected to the wrong headers, said it back on the last page. Never realised every motherboard power headers were always called JFP1.


Good job you got it fixed.

It's kind of a convention, JFP = Jumper Front Panel

Glad you got it sorted.
